The implementation of the GNUstep GUI Library is designed in two parts. The first part is the front-end component which is independent of platform and display system. This front-end is combined with a back-end component which handles all of the display system dependent such as specific calls to the X Window System. This design allows the GNUstep applications to have the "look and feel" of the underlying display system without any changes to the application, and the library can be easily ported to other display systems. The GNUstep GUI Backend is for platforms using the X-Window System or Window's Systems. It works via a DPS emulation engine to emulate the DPS functions required by the front-end system. 1.2 Noteworthy changes in version `0.25.0' ========================================== Implement per gstate methods for antialias, patternPhase and compositingOperation in Cairo backend. Work on antialiasing in Cairo backend. Variety of bugfixes, especially in Win32 and Cairo backends. 1.3 Where can you get it? How can you compile it? ================================================== The gnustep-back-0.25.0.tar.gz distribution file has been placed at `ftp://ftp.gnustep.org/pub/gnustep/core'. It is accompanied by gnustep-back-0.25.0.tar.gz.sig, a PGP signature which you can validate by putting both files in the same directory and using: `gpg --verify gnustep-back-0.25.0.tar.gz.sig' Signature has been created using the key with the following fingerprint: `83AA E47C E829 A414 6EF8 3420 CA86 8D4C 9914 9679' Read the INSTALL file or the GNUstep-HOWTO for installation Instructions. 1.4 Where do I send bug reports? ================================ Bug reports can be sent to the GNUstep bug list 1.5 Obtaining GNU Software ========================== Check out the GNUstep web site.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read . gnustep-back-0.25.0/COPYING.LIB000066400000000000000000000635061273700670400156410ustar00rootroot00000000000000 GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

Evaluate CGCTX only once per method. 2013-09-29 Fred Kiefer * Headers/opal/OpalGState.h: Clean up to reduce warnings. * Source/opal/OpalGState.m: Add missing path and matrix methods. Remove warnings. Remove unneeded code. Reorder code to allow for easier comparison with GSGState. * Source/opal/OpalContext.m: Add missing includes to get shm completion working. Adjust to changes in OpalGState. 2013-09-23 Eric Wasylishen * Source/opal/OpalGState.m: move variable declaration outside of for loop 2013-09-23 Ivan Vucica * Source/opal/OpalGState.m: Fixed a compile error (extra #endif). Added -DPSsetdash:::. Added stub -DPSsetstrokeadjust:. 2013-09-23 Ivan Vucica * Source/opal/OpalGState.m: * Source/opal/OpalSurface.m: Cutting down on junk code and unneeded output. 2013-09-23 Ivan Vucica * Source/opal/OpalContext.m: Once again pretending we're not drawing on screen. This is a temporary fix for -DPSimage:. -DPSgsave is now passed on to current gstate before GSContext is given chance to replace it. Changes relating to rename of OpalSurface and OpalGState methods -cgContext to -CGContext. * Source/opal/OpalGState.m: Apparently mostly functional -compositeGState:. Includes disabled modification of code from CairoGState. Apparently functional -drawGState. -DPSsetlinecap: stub (need to match linecap constants.) -DPSsetmiterlimit:. Extended -copyWithZone: to assign a 'default' OpalGStateRef to the newly copied gstate in case we currently have no context. This is done by creating a context and copying whatever's in that context onto the new OpalGState. Improved -DPSinitgraphics by setting the device offset that was set here and calling CGContextSaveGState() as many times as it was supposed to be called while CGContext did not exist. Noted that we should, instead of recreating contexts, just reset the internal GState of Opal. Added -GSSetCTM:. -flushGraphics no longer 'flushes' rect 0,0,1024,1024. Now it instead queries surface for its size. In case surface exists but not the CGContext, -DPSgsave creates it. Otherwise, it records that gsave should be run upon context creation. Added -DPSsetlinewidth:. Changes relating to rename of OpalSurface and OpalGState methods -cgContext to -CGContext. * Source/opal/OpalSurface.m: Added reminder of how we should handle recreation of CGContexts. Disabled non-doublebuffered windows. (We always need a backing CGBitmapContext so we can implement -compositeGState: and -drawGState:. Added accessors -x11CGContext and -backingCGContext. Fixed bug where sometimes we'd get incorrect expose values and would try to incorrectly copy the backing image, stretching the resulting on-screen image. Added -size accessor. * Headers/opal/OpalGState.h: Some accessors. _CGContextSaveGStatesOnContextCreation ivar. * Headers/opal/OpalSurface.h: New and renamed accessors. 2013-09-19 Ivan Vucica * Source/opal/OpalContext.m: Added GState switcher -DPSsetgstate:. See description of _opGState in OpalGState.h. * Headers/opal/OpalGState.h: Added _opGState i-var and relevant accessors. * Source/opal/OpalGState.m: Instead of yellow rectangle, -compositeGState:... method *should* now be painting doublebuffered content from the 'other' GState, but sadly does not. This needs debugging. Implemented -copyWithZone:. See description of _opGState in OpalGState.h to see how and why is _opGState used in this class, how it is being copied and why it's alright to keep it nil during -init and even after -DPSinitgraphics, but needs to be set in -copyWithZone:. Added -setOPGState: and -OPGState accessors for the _opGState field. 2013-09-18 Ivan Vucica * Source/opal/OpalSurface.m: Enabled doublebuffering. Fixed some debug code, disabled some other debug code. 2013-09-17 Eric Wasylishen * Source/opal/OpalFontInfo.m: Use new OPFontGetGlyphWithCharacter to properly look up the glyph for a character. 2013-09-17 Ivan Vucica * Source/opal/OpalFontInfo.m: Removed some dead code. * Source/opal/OpalGState.m: Fixed erroneous offset of glyphs by taking -defaultLineHeightForFont, multiplying by 0.66, and adding that to pt.y. No idea why 0.66 is the right number. 2013-09-17 Ivan Vucica * Source/opal/OpalContext.m: Added note that -supportsDrawGState should be implemented. * Source/opal/OpalGState.m: Fixed temporary code for painting colored rectangles in place of text. Partially fixed -GSShowGlyphsWithAdvances::: by removing temporary code for painting colored rectangles, and by setting text matrix in GSSetFont:. 2013-09-17 Eric Wasylishen * Source/opal/OpalFontInfo.m: Move font space to user space conversion to a separate method. Implement -glyphIsEncoded:, -advancementForGlyph:, -glyphForCharacter:, -glyphWithName:. For -boundingRectForGlyph:, and -widthOfString:, return fake, fixed values. * Source/opal/OpalContext.m: Fix -isDrawingToScreen implementation; it now returns YES. This has the unfortunate side effect of breaking image drawing... but, on the positive side, causes NSLayoutManager to make calls to GSShowGlyphsWithAdvances in batches of up to 16 glyphs, instead of one at a time...! * Source/opal/OpalGState.m: Implement -GSSetFont:, and make -GSShowGlyphsWithAdvances: call CGContextShowGlyphsWithAdvances Overall state is glyphs are drawn.. they appear upside down, and the glyph runs only seem to draw at (0, 0). 2013-09-17 Ivan Vucica * Source/opal/OpalFontInfo.m: Fixed scale of metrics by using unitsPerEm and pointSize. 2013-09-17 Ivan Vucica * configure: * configure.ac: Added fontconfig and freetype as dependencies for Opal. configure script is not actually regenerated from configure.ac and contains a simplified piece of code which just appends relevant options to CPPFLAGS and LIBS. * Source/opal/GNUmakefile: Added fontconfig/ implementation files, like it was done in cairo backend. * Headers/opal/OpalFaceInfo.h: * Source/opal/OpalFaceInfo.m: Now copied from CairoFaceInfo and modified to use Core Graphics. * Headers/opal/OpalFontInfo.h: * Source/opal/OpalFontInfo.m: Now copied from CairoFontInfo. Starting modifying to use the Core Graphics. Currently font metrics are not correctly scaled. * Source/opal/OpalFontEnumerator.m: * Headers/opal/OpalFontEnumerator.h: Now copied from CairoFaceInfo. Modified to use the classes in the Opal backend. * Source/opal/OpalGState.m: Added DPSrlineto:: and DPSrmoveto::. * Source/fontconfig/FCFontInfo.m: * Headers/fontconfig/FCFontInfo.h: Removed a cairo-backend-specific method. 2013-09-10 Ivan Vucica * Source/fontconfig/FCFontInfo.m: * Source/fontconfig/FCFontEnumerator.m: * Source/fontconfig/FCFaceInfo.m: * Headers/fontconfig/FCFontInfo.h: * Headers/fontconfig/FCFontEnumerator.h: * Headers/fontconfig/FCFaceInfo.h: * Source/cairo/CairoFontEnumerator.m: * Source/cairo/CairoFaceInfo.m: * Source/cairo/CairoFontInfo.m: * Headers/cairo/CairoFontInfo.h: * Headers/cairo/CairoFontEnumerator.h: * Headers/cairo/CairoFaceInfo.h: In preparation for reusing this code in the Opal backend, moved fontconfig code to a dedicated set of classes that are now superclasses of Cairo backend's font classes. * Source/cairo/GNUmakefile: Added fontconfig font classes directly to GNUmakefile for Cairo backend. It would be better if these had something like their own distinct GNUmakefile that produces a static library which would then be linked into Cairo. But the only backends that will use this are, for now, Cairo and Opal. So the ugliness and extra maintenance in case more classes are added should be, for now, acceptable. * Source/cairo/CairoGState.m: Fixed a mistake in a NSDebugMLLog() call's format. A percentage symbol was placed before word "self", resulting in compiler's interpretation as "%s". 2013-09-10 Eric Wasylishen * Source/x11/XIMInputServer.m: If the requested XIM style (the GSXIMInputMethodStyle user default) is not available, fall back to using a stlye that both the X server and GNUstep support, if any. Also, add support for NoneStyle, which is for simple input methods that don't have any visualization. Problem reported and tested by Riccardo. 2013-09-09 Ivan Vucica * Source/opal/OpalFontInfo.m: Implemented -defaultLineHeightForFont, the key to getting GNUstep layouting system to use information provided in -advancementForGlyph:. Without that, the textcontainer->linefrags does not get created. 2013-09-08 Fred Kiefer * Source/x11/XGGLContext.m, * Source/x11/XGGLFormat.m: Better error reporting by converting glGetError() to a string. 2013-08-21 Eric Wasylishen * Source/x11/XIMInputServer.m: Add the setlocale(LC_CTYPE, "") call back that I removed last year (r35152). I tested the fcitx input method, and without the setlocale call, XOpenIM would fail. I'm not sure what the best plan is in the long term, I wanted to avoid calling setlocale from the core frameworks but in this case xlib seems to require it. 2013-08-02 Ivan Vucica * Source/opal/OpalContext.m: Implementation of -graphicsPort that returns a CGContext * Source/opal/OpalGState.m: -Stubs for -DPSsetlinejoin:, -DPSsetlinecap:, -DPSsetmiterlimit: -Implementation of -DPSimage::::::::::: for 32-bit RGB colorspaces 2013-07-29 Fred Kiefer * Source/gsc/GSContext.m: Replace isa with object_getClass(). 2013-07-25 Ivan Vucica * Source/opal/OpalContext.m: Pushing -DPSgsave: and -DPSgrestore: to OpalGState. * Source/opal/OpalSurface.m: -Disabled doublebuffering temporarily. -Work on fixing doublebuffering, including creating subimage properly. -Richer debug image output code, plus saving as PNGs. * Source/opal/OpalGState.m: -DPSfill -Setting color now also sets stroke color. -Corrected name for -DPSgsave and -DPSgrestore. -Implemented -saveClip, -restoreClip. -Implemented -DPSeoclip and -DPSeofill. -Added dummy DPSshow:, GSShowText:: etc. -Implemented -DPScurrentpoint:: so that superclass's DPSrlineto:: works. * Headers/opal/OpalSurface.h: Added -createCGContexts to header to fix a warning. 2013-07-24 Fred Kiefer * Source/win32/w32_movesize.m (-decodeWM_EXITSIZEMOVEParams:::): Remove code that caused missing windows content. * Source/cairo/CairoContext.m (-flushGraphics): Add experimental flush code for Windows. * Source/cairo/Win32CairoSurface.m (-initWithDevice:, -dealloc): Clean up HDC handling. Based on patch by Marcian Lytwyn 2013-07-24 Ivan Vucica * configure.ac: * configure: Opal backend depends on both Opal and CoreBase. Added CoreBase to list of libraries we link with. * Source/opal/OpalFontInfo.m: * Source/opal/OpalFontEnumerator.m: Switched to NSDebugLLog(). * Source/opal/OpalGState.m: -Switched to NSDebugLLog(). -Fixed DPSimage method's conversion of NSAffineTransform to CGAffineTransform -Implemented GSCurrentCTM -Implemented flushGraphics -Implemented DPSsavegstate and DPSrestoregstate * Source/opal/OpalSurface.m: -Switched to NSDebugLLog(). -Fixed section that is supposed to write out the debug image. 2013-07-21 Ivan Vucica * Source/opal/OpalFontInfo.m: * Source/opal/OpalFontEnumerator.m: Some hacks to figure out how NSMenuItem's width is determined, and how the supported glyphs are determined. * Source/opal/OpalGState.m: Various method implementations and fixes. * Source/opal/OpalSurface.m: Enabled doublebuffered code path, now that Opal's endianess problem is fixed. Creation of CGContext factored out of initializer into a method that can be called whenever needed to recreate the context. 2013-07-15 Ivan Vucica * Source/opal/OpalFontEnumerator.m: * Source/opal/OpalFontInfo.m: More dummy font code, trying to get wider menu items et al. * Source/opal/OpalSurface.m: * Source/opal/OpalContext.m: * Headers/opal/OpalSurface.h: Work on getting backing store support to work. * Source/opal/OpalGState.m: * Headers/opal/OpalGState.h: Implementation of a lot of drawing and matrix methods. 2013-07-11 Ivan Vucica * Source/opal/OpalContext.m: Once the surface is created in context, it's also set as the active surface of the GState. * Source/opal/OpalGState.m: Blocked some superclass methods from running. Added debug output. Added call to dummy paint method in OpalSurface. * Source/opal/OpalSurface.m: * Headers/opal/OpalSurface.h: * Headers/opal/OpalGState.h: Opal context is now created in the surface. Added a dummy draw method. * configure.ac: * configure: Ensured linking with the Opal library. 2013-07-08 Fred Kiefer * Source/x11/XGServerWindow.m (-setIgnoreMouse::): Completely rewrite this method to use Xfixes. * Source/win32/WIN32Server.m (-setIgnoreMouse::): Implement a Windows version of this method. 2013-07-08 Fred Kiefer * Source/x11/XGServerWindow.m (-setIgnoreMouse::): New method that allows to ignore mouse events for a window. 2013-07-04 Richard Frith-Macdonald * Tools/GNUmakefile.preamble: * Source/GNUmakefile.preamble: Fix order of use of library and header directories. 2013-07-03 Ivan Vucica * Source/x11/XGGLFormat.m: * Headers/x11/XGOpenGL.h: ARGB visual is only picked if NSOpenGLPFAAlphaSize is specified in the pixel format. 2013-07-03 Ivan Vucica * Source/x11/XGGLContext.m: * Source/x11/XGGLFormat.m: * Headers/x11/XGOpenGL.h: OpenGL context under X11 now picks up the best possible framebuffer that includes an alpha mask in the X visual info. The code is currently disabled as it needs more debugging. 2013-06-27 German A. Arias * Source/x11/XGServerEvent.m (-processEvent:): Don't add events WindowResized and WindowMoved in event_queue, to don't delay its sent. Instead, send these directly to the window. If not, the programa can move/resize the window while we send these events, causing a confusion. 2013-06-25 Ivan Vucica * Source/opal/OpalFontInfo.m: * Source/opal/OpalContext.m: * Source/opal/OpalGState.m: * Source/opal/OpalFontEnumerator.m: * Source/opal/OpalSurface.m: * Headers/opal/OpalFontInfo.h: * Headers/opal/OpalContext.h: * Headers/opal/OpalGState.h: * Headers/opal/OpalFontEnumerator.h: * Headers/opal/OpalSurface.h: Minimal code for dummy graphics backend now implemented for Opal backend. 2013-06-23 Ivan Vucica * config.h.in: * configure.ac: * configure: * Source/GSBackend.m: Added Opal backend to appropriate places (avoiding rebuild of configure and config.h.in). * Source/opal/OpalPSSurface.m: * Source/opal/GNUmakefile: * Source/opal/OpalFontInfo.m: * Source/opal/OpalPDFSurface.m: * Source/opal/OpalContext.m: * Source/opal/OpalGState.m: * Source/opal/OpalFontEnumerator.m: * Source/opal/OpalSurface.m: * Source/opal/OpalFaceInfo.m: Added dummy files for the Opal backend. 2013-05-11 Fred Kiefer * Source/cairo/Win32CairoSurface.m (-initWithDevice:): Make safer against the surface being deallocated during this method. * Source/cairo/Win32CairoSurface.m (WIN32Server-contentsOfScreen:inRect:): Screen grabbing code. * Headers/win32/WIN32Server.h, * Source/win32/WIN32Server.m (-monitorHandleForScreen:, -createHdcForScreen:, deleteScreenHdc:): Add helper methods for screen grabbing. Patch by Marcian Lytwyn 2013-04-24 23:10-EDT Gregory John Casamento * Source/cairo/CairoGState.m: Added code in -drawGradient: fromPoint:toPoint:options: to handle gradients for colorspaces other than NSCalibratedRGBColorSpace, NSDeviceRGBColorSpace, NSCalibratedWhiteColorSpace, NSDeviceWhiteColorSpace, NSCalibratedBlackColorSpace, NSDeviceBlackColorSpace. The previous implementation assumed RGB based colorspaces only. 2012-03-01 Richard Frith-Macdonald * Version ... bump subminor number in preparation for next release. 2012-03-01 Richard Frith-Macdonald Make release * Version 0.23.0 * Update release notes 2013-02-18 Fred Kiefer * Source/x11/XGServerWindow.m Fix compiler warnings reported by Sebastian Reitenbach 2013-02-16 Fred Kiefer * Source/gsc/GSContext.m * Source/x11/XGServerWindow.m Adopt to changes in gui. 2013-02-10 Fred Kiefer * Headers/cairo/CairoGState.h * Source/cairo/CairoGState.m * Source/cairo/XGCairoXImageSurface.m * Source/gsc/GSContext.m * Source/gsc/GSStreamContext.m * Source/gsc/GSStreamGState.m * Source/x11/XGServerWindow.m * Source/x11/XGDragView.m: Silence warnings from clang. 2013-02-01 Fred Kiefer * Source/winlib/WIN32Context.m(-isCompatibleBitmap): Add missing varible. 2013-02-01 Fred Kiefer * Headers/gsc/GSGState.h * Headers/gsc/GSGStateOps.h * Headers/gsc/GSStreamGState.h * Source/art/ARTGState.m * Source/art/composite.m * Source/art/ftfont-old.m * Source/art/ftfont.h * Source/art/ftfont.m * Source/art/path.m * Source/cairo/CairoGState.m * Source/gsc/GSContext.m * Source/gsc/GSGState.m * Source/gsc/GSStreamContext.m * Source/winlib/WIN32GState.m * Source/xlib/XGGState.m: Adopt to CGFloat changes in DPS/PS functions of gui. 2013-02-01 Fred Kiefer * Source/cairo/CairoGState.m * Source/gsc/GSGState.m * Source/gsc/GSStreamContext.m * Source/winlib/WIN32GState.m: Adopt to CGFloat changes on NSBezierPath. 2013-01-27 Fred Kiefer * Source/gsc/GSContext.m * Source/cairo/CairoContext.m * Source/art/ARTContext.m * Source/xlib/XGContext.m * Source/winlib/WIN32Context.m: Move the bitmap conversion code from cairo to the gsc class. Add a new method to detect incompatible image formats and implement that for all backends. * Source/winlib/WIN32GState.m (GSCreateBitmap): Improve the handling of device black/white colour space. 2013-01-11 Fred Kiefer * Source/win32/w32_general.m (-decodeWM_CLOSEParams:::): Post the close event instead of sending it directly to the window. Patch by Doug Simons 2013-01-05 00:54-EST Gregory John Casamento Merging changes made by Marcian Lytwyn * Tools/win32pbs.m: (+ownerByOsPb:) compare against name instead of pasteboard object to prevent condition where paste works only once as observed on Windows. (MainWindowProc) Add code to handle WM_RENDERALLFORMATS as documented on MSDN here: http://msdn.microsoft.com/en-us/library/windows/desktop/ms649029(v=vs.85).aspx 2012-12-31 Fred Kiefer * Source/cairo/CairoFntInfo.m (-drawGlyphs:..., -setupAttributes): Invert the value of matrix[2].

As a result, this eliminates a gtable memory leak (e.g. +initialize sent to both GSContext and CairoContext at backend initialization time), and prevents the gstate stack to be reset while still in use (e.g. the program enumerates classes at runtime and sends messages to them... +initialize might be sent to GSStreamContext in such a case). 2012-05-12 Eric Wasylishen * Source/x11/XIMInputServer.m: Remove the locale setting code. Use the correct #ifdef check for Xutf8LookupString, and use that function if available; otherwise use XLookupString. Interpret the return value of XLookupString as Latin-1. 2012-03-22 Eric Wasylishen * Source/x11/XGServerEvent.m: Make the GSModifiersAreKeys default to YES, by renaming the default to GSModifiersAreNotKeys. This should fix bug 25659; for example, in Ink you can now open the color panel with ++c or ++c. * Documentation/Back/DefaultsSummary.gsdoc: Update docs for GSModifiersAreNotKeys. 2012-02-20 Fred Kiefer * Source/cairo/CairoGState.m: Set the filter to BILINEAR for all patterns we use. 2012-02-19 Wolfgang Lux * Source/gsc/GSGState.m (-GSSetFillColor:, -GSSetStrokeColor:): Fix potentially uninitialized color space element when setting fill and stroke colors. 2012-02-19 Fred Kiefer * Source/cairo/CairoGState.m (-compositerect:op:): Use difference operator only for cairo version >= 1.9.4. 2012-02-18 Fred Kiefer * Source/winlib/WIN32GState.m * Source/art/composite.m * Source/xlib/XGGState.m * Source/xdps/NSDPSContextOps.m: Replace NSCompositeHighlight with GSCompositeHighlight and map NSCompositeHighlight onto NSCompositeSourceOver. * Source/cairo/CairoGState.m (-compositerect:op:): Implement GSCompositeHighlight with the difference operator. 2012-02-09 Richard Frith-Macdonald * Tools/gbps.m: Add lots of debug information (have objects describe themselves and where they are in the data sturcture). Simplify code by removing cached information about which owners respond to which selectors (probably not needed on modern systems, and we could re-add this more simply if it turns out I'm wrong). 2012-02-03 Adam Fedor * Bump version 2012-02-03 Adam Fedor * Version 0.22.0 * Update release notes 2012-01-23 Eric Wasylishen * Source/cairo/CairoFntInfo.m (-setupAttributes): use CAIRO_HINT_METRICS_ON instead of CAIRO_HINT_METRICS_OFF, otherwise some text is cut of (e.g. quit Ink with unsaved changes, the "t" in "Quit" in the dialog is cut off) 2012-01-23 Eric Wasylishen * Source/cairo/CairoFontInfo.m (-setupAttributes): We must not leave the hinting settings as their defaults, because if we did, that would mean using the surface defaults which might or might not use hinting (xlib does by default.) Since we make measurements outside of the context of a surface (-advancementForGlyph:), we need to ensure that the same hinting settings are used there as when we draw. For now, just force hinting to be off. 2012-01-19 Wolfgang Lux * Source/x11/XGServerWindow.m (-orderwindow:::): Introduce new user defaults to respectively make app icons and mini windows sticky (aka omnipresent). 2012-01-11 Fred Kiefer * Source/winlib/WIN32FontEnumerator.m: Add missing include. 2012-01-11 Fred Kiefer * Source/winlib/WIN32FontEnumerator.m, * Source/cairo/CairoFontEnumerator.m, * Source/xlib/GSXftFontInfo.m, * Source/xlib/XGFont.m: Use NSDebugLLog instead of NSDebugLog to reduce amount of default output. 2012-01-02 Eric Wasylishen * Source/cairo/CairoGState.m (-GSShowGlyphsWithAdvances:): Update the current point after drawing text. Should not affect anything in gui right now, but will be useful later. 2011-12-24 Eric Wasylishen * Source/cairo/CairoContext.m (-beginPrologueBBox:...): Add a hack to get landscape printing working. Comment in the source reproduced here: FIXME: This is confusing... When an 8.5x11 page is set to landscape, NSPrintInfo also swaps the paperSize to be 11x8.5, but gui also adds a 90 degree rotation as if it will be drawing on a 8.5x11 page. So, swap 11x8.5 back to 8.5x11 here. 2011-12-23 Eric Wasylishen * Source/cairo/CairoContext.m (-beginPrologueBBox:...): Use paper size from print info to set the cairo page size, instead of using the bounding box (which is usually smaller than the paper size, and was causing cairo print output to be wrong compared to GNUstep's built-in PostScript writer.) 2011-11-28 Fred Kiefer * Source/x11/XGServerEvent.m (initialize_keyboard): Don't use XK_ISO_Level3_Shift as second alternate key. * Documentation/Back/DefaultsSummary.gsdoc: Document this mapping. 2011-11-07 Fred Kiefer * Source/x11/XGGLFormat.m (-assembleGLXAttributes:): Use GLX_BUFFER_SIZE for NSOpenGLPFAColorSize instead of setting all the single colour sizes, which was wrong. 2011-11-07 Fred Kiefer * Source/x11/XGServerEvent.m (initialize_keyboard): Use XK_ISO_Level3_Shift as second alternate key. * Documentation/Back/DefaultsSummary.gsdoc: Document this mapping. 2011-11-04 Eric Wasylishen * Source/x11/context.c: check for NULL from XRenderFindVisualFormat 2011-10-25 Eric Wasylishen * Source/gsc/GSStreamContext.m: * Source/gsc/GSContext.m: * Source/gsc/GSGState.m: * Headers/gsc/GSGStateOps.h: Change type for -GSSetFillColor: and -GSSetStrokeColor: from float to CGFloat 2011-10-20 Fred Kiefer * Source/cairo/CairoFontEnumerator.m: Define FC_WEIGHT_ULTRABLACK for old versions of fontconfig. Patch by Richard Frith-Macdonald 2011-10-20 Fred Kiefer * Headers/x11/XWindowBuffer.h: Bracket even more usage of shm in conditional compilation. 2011-10-18 Fred Kiefer * Headers/x11/XWindowBuffer.h: Protect the usage of shm. 2011-10-17 Fred Kiefer * configure.ac: Test for X shape extension * configure: Regenerate * config.h.in: Regenerate * Source/x11/XGServerWindow.m (-restrictWindow:toImage:), * Source/x11/XWindowBuffer.m (-_exposeRect:): Protect usage of shape extension. Should fix bug #34552. 2011-10-13 Eric Wasylishen * Source/cairo/GNUmakefile: * Source/cairo/CairoContext.m: * Source/cairo/CairoSurface.m: * Source/cairo/XGCairoModernSurface.m: * Headers/cairo/XGCairoModernSurface.h: * Headers/cairo/CairoSurface.h: New cairo surface which uses cairo_surface_create_similar to create a back buffer which has an alpha channel, even if the X server doesn't support surfaces with alpha. This new surface is also made the default since this seems to be the recommended way to double buffer with cairo. 2011-09-18 Eric Wasylishen * Source/cairo/CairoContext.m: revert the last change for now 2011-09-16 Eric Wasylishen * Source/cairo/CairoContext.m: Switch to XGCairoSurface by default, because it fixes the corrupted display problem reported by Riccardo on 16-bit displays. 2011-09-12 Fred Kiefer * Source/cairo/CairoGState.m (-saveClip, -restoreClip:, -drawGradient:...): Check that the _ct isnt NULL. * Source/cairo/CairoGState.m (doubleFromUserSpace, floatToUserSpace): Use correct types in these helper functions. 2011-09-12 Fred Kiefer * Source/x11/XGDragView.m (GSActionForDragOperation, GSDragOperationForAction): Corrected drag type conversion. Patch by Andreas Schick 2011-09-11 Eric Wasylishen * Source/cairo/CairoGState.m (-drawGState:...): Check that the source context is non-NULL before calling cairo_get_target on it. Log a warning when either the source context or target context is NULL. 2011-08-16 Eric Wasylishen * Source/cairo/CairoGState.m (-drawGState:...): Use CAIRO_EXTEND_PAD on the pattern to prevent blurred edges when scaling up. 2011-08-15 Eric Wasylishen * Source/cairo/CairoGState.m (-DPSstroke:): If the line width is 0, temporarily set it to 1 unit wide (in device space.) This is an attempt at matching the behaviour of the setlinewidth PostScript operator, which is supposed to interpret 0 as meaning the thinnest line that the output device can draw. Note that Quartz (and cairo) draw nothing with a line width of 0. 2011-08-07 Eric Wasylishen * Tools/xpbs.m: Add some more comments 2011-08-07 Eric Wasylishen * configure.ac: Test for Xfixes * configure: Regenerate * config.h.in: Regenerate * Tools/xpbs.m: If Xfixes is available, use it to receive notifications when the owner of an X11 selection changes. In the future we should invalidate the list of cached pasteboard types when this happens, so, e.g. copying text from gnome-terminal, the general pasteboard will only have the text type, but subsequently copying text from OpenOffice.org, the general pasteboard will have plain text and RTF types (currently we don't do this, so you can't paste RTF contents unless it is in the clipboard when gpbs starts.) The above problem is also why DND from X to GNUstep doesn't work - the dragging pasteboard types are never updated. 2011-08-04 Eric Wasylishen * Tools/xpbs.m: Get copy and paste of rich text from OpenOffice.org to Ink working. - OOo uses the MIME type "text/richtext", so make that another alias for RTF - Fix an obscure bug in measuring the size of the return buffer of XGetWindowProperty. When an array of Atom's is returned xlib will claim that they are 32-bit when in fact they may be 64-bit. This was causing xpbs to miss half of the available types for a clipboard on 64-bit systems. - Don't use 'True' for the delete paramater of XGetWindowProperty. I'm not sure why we were deleting window properties before. gtk doesn't do that. 2011-08-01 Eric Wasylishen * configure.ac: Add a configure test for Xcursor * configure: regenerate * config.h.in: regernate 2011-07-30 Eric Wasylishen * Source/win32/WIN32Server.m (-resolutionForScreen:): Scale the result by 0.75 so the Windows default of 96 DPI is mapped to the GNUstep default of 72 DPI. While this sounds wrong, 72 and 96 are just "virtual" DPI's; both mean 1 point = 1 pixel, so it's actually the right thing to do. * Source/x11/XGServerWindow.m (-resolutionForScreen:): Comment out the implementation and just return 72 for now, because I'm not sure if we can trust the value the X server gives us. NOTE: Currently -gui ignores these methods and only looks at the GSScaleFactor user default. I'm going to make -gui use the server values now, because it's safe to do so on Windows (the system DPI is set by the user, and affects all applications.) NOTE: We might consider refactoring these methods to be called scaleFactorForScreen: to make it clearer what they do. 2011-07-18 Eric Wasylishen * Source/winlib/WIN32GState.m (GSCreateBitmap): Add support for (8 bit-greyscale, 8-bit alpha) format. This fixes various default images not showing (menu arrows, scroller arrows, etc.) 2011-07-15 Eric Wasylishen * Source/x11/XGServerWindow.m: Add Xcursor support (for RGBA imagecursor support.) configure test is still TODO, so it isn't compiled in at the moment. 2011-07-13 Eric Wasylishen * Headers/x11/XGGeneric.h * Source/x11/XGServerWindow.m: Add new netwm window state atoms 2011-07-14 Fred Kiefer * Tools/win32pbs.m: Add include needed for Cygwin. 2011-07-08 Eric Wasylishen * Headers/cairo/CairoGState.h: * Source/cairo/CairoGState.m: Remove most of the rounding code and implementation of DPSstrokeadjust. 2011-07-03 Eric Wasylishen * Source/cairo/XGCairoSurface.m (-contentsOfScreen:inRect:): Use the passed rect properly. 2011-07-03 Eric Wasylishen * Source/cairo/XGCairoSurface.m: Implementation of -[GSDisplayServer contentsOfScreen:inRect:] for x11/cairo 2011-06-22 Fred Kiefer * Headers/x11/XGServer.h: Add #include of config.h. 2011-06-15 Fred Kiefer * Source/cairo/CairoContext.m (-supportsDrawGState), * Headers/cairo/CairoGState.h (-supportsDrawGState) * Source/cairo/CairoGState.m (-supportsDrawGState): Revert last change as gui is fixed now. 2011-06-13 Fred Kiefer * Source/cairo/CairoContext.m (-supportsDrawGState): Delegate to gstate. * Headers/cairo/CairoGState.h (-supportsDrawGState): Declare this method. * Source/cairo/CairoGState.m (-supportsDrawGState): Only allow the faster drawing operation when the clip can be represented as a list of rectangles. * Source/cairo/CairoGState.m (-copyWithZone:): Always free the clip rectangle list. 2011-06-01 Wolfgang Lux * Headers/x11/XGServerWindow.h (GSMaxWMProtocols, _gswindow_device_t): Enlarge protocol array to make space for the _NET_WM_SYNC_REQUEST protocol atom. * Source/x11/XGServerWindow.m (_setSupportedWMProtocols:): Add assertion to catch out of bounds errors in the future. 2011-05-27 13:53 David Chisnall * libs/back/trunk/Source/x11/XGServerWindow.m: Call NSZoneFree() on pointer allocated with NSAllocateCollectable(), not free(). This is a no-op in GC mode, and will free the memory in non-GC mode. 2011-05-25 Eric Wasylishen * Source/winlib/WIN32GState.m: * Source/art/ARTGState.m: * Source/cairo/CairoGState.m: * Source/xlib/XGGState.m: * Source/gsc/GSContext.m: * Source/gsc/GSGState.m: * Headers/gsc/GSGStateOps.h: Add a new interface, GSShowGlyphsWithAdvances, which replaces GSShowGlyphs as the primitive text drawing method. None of the backends implement it properly yet; I simply renamed the existing -GSShowGlyphs:: methods to -GSShowGlyphsWithAdvances:::, so they currently ignore the glyph advances. 2011-05-19 Fred Kiefer * Headers/cairo/CairoFontEnumerator.h, * Headers/cairo/CairoFaceInfo.h: Protect the name id. * Source/cairo/CairoGState.m: Reorder variable declarations before GS_BEGINITEMBUF as some compilers may complain. Patch by Sebastian Reitenbach 2011-05-15 Eric Wasylishen * Source/x11/XGServerWindow.m: * Source/x11/XGServer.m: * Source/x11/XGServerEvent.m: * Headers/x11/XGGeneric.h: * Headers/x11/XGServerWindow.h: * Headers/x11/XGServer.h: Implement the _NET_WM_SYNC_REQUEST protocol described here: http://standards.freedesktop.org/wm-spec/1.3/ar01s06.html This is supposed to make window resizing smoother when dragging a resize handle provided by the window manager, by waiting to change the window manager's frame until the GNUstep window is finished repainting. 2011-05-05 Eric Wasylishen * Undo the previous change and try a different approach.. just cache the character set in CairoFaceInfo, but load them as needed as we were doing before. 2011-05-05 Eric Wasylishen * Source/cairo/CairoFontEnumerator.m: * Source/cairo/CairoFaceInfo (-characterSet): Remove the call to FcFontMatch in -characterSet which was a big performace bottleneck. Instead load the character set data when enumerating all fonts in CairoFontEnumerator. 2011-04-17 Eric Wasylishen * Source/cairo/CairoFontEnumerator.m: Remove declarations after statements for c89 compatability 2011-04-17 Eric Wasylishen * Source/cairo/CairoFontEnumerator.m: Replace -handleKey:selector:valueClass: and -handleKey:selector: methods with macros. 2011-04-17 Eric Wasylishen * configure.ac: Copy the -Wdeclaration-after-statement test from base. Also adds -Wall. 2011-04-14 Eric Wasylishen * Source/cairo/CairoFontEnumerator.m: * Headers/cairo/CairoFontEnumerator.h: Override -matchingFontDescriptorsFor: to delegate the matching to Fontconfig This uses two utility classes which map Fontconfig patterns to and from NSFontDescriptor attributes dictionaries, preserving as much detail as possible. 2011-04-14 Adam Fedor * Version: Bump version 2011-04-14 Adam Fedor * Version 0.20.0 2011-04-09 Fred Kiefer * Source/gsc/GSFunction.m (-initWith:): Correct printf format. * Source/x11/XGServerEvent.m (-XGErrorHandler::, -_XPointToOSPoint:for:, -processEvent:, -_handleTakeFocusAtom:forContext:, process_key_event): Correct printf format. * Source/x11/XGServerWindow.m (setNormalHints, -_OSFrameToXFrame:for:, -_OSFrameToXHints:for:, -_XFrameToOSFrame:for:, -_checkStyle:, -nativeWindow:...:, -styleoffsets:...:, -placewindow::, -setinputfocus:, -_DPSsetcursor::): Correct printf format. * Source/x11/XGServerWindow.m (-orderwindow): Remove misplaced semicolon. * Source/x11/XGDragView.m (-_resetDragTypesForWindow:): Correct printf format. * Source/x11/XIMInputServer.m (-ximStyleInit, -ximFocusICWindow:): Correct printf format. * Source/x11/XWindowBuffer.m: Correct printf format. * Source/GSBackend.m: Replace objc_get_class with NSClassFromString. * Tools/xpbs.m (-xSelectionNotify:): Correct printf format. Fixes warnings reported by clang. 2011-03-27 Eric Wasylishen * Source/cairo/CairoFontEnumerator.m: * Source/cairo/CairoFaceInfo.m: * Source/cairo/CairoFontInfo.m: * Headers/cairo/CairoFontEnumerator.h: * Headers/cairo/CairoFaceInfo.h: Set the coveredCharacterSet ivar of CairoFontInfo. The character set is obtained from Fontconfig. There is an NSCharacterSet subclass which wraps the FcCharSet structure from fontconfig, so there is no need for a slow conversion from one character set format to another. This has the effect of enabling glyph substitution when using the cairo backend. 2011-03-23 Fred Kiefer * Tools/xpbs.m (-pasteboard:provideDataForType:, -availableTypes) (-xSelectionNotify:): Better handling of plain text data types. 2011-03-18 Fred Kiefer * Source/x11/XGServerWindow.m: Extract the bitmap conversion into a local function and use it througout the file. 2011-03-13 Eric Wasylishen * configure.ac: Check for the X extention libraries (Xext, Xt, Xmu) using pkg-config if they aren't found with the default test 2011-03-07 Fred Kiefer * Source/win32/WIN32Server.m, * Source/x11/XGServerWindow.m: Change the way the image for the cursor gets passed on to the backend. The old way could only work for 8 bit data. 2011-03-05 Wolfgang Lux * Tools/xpbs.m (+xEvent:, +receivedEvent:type:extra:, -requestData:, -xTimeByAppending): Fix race condition where gpbs could time out waiting for a property change notification from the X server, which is already present in the X event queue. 2011-02-15 Fred Kiefer * Source/win32/WIN32Server.m, * Source/x11/XGServerWindow.m: New methods for cursor handling. Requires corresponding gui change. 2011-02-14 Wolfgang Lux * Source/x11/XGServerWindow.m (-orderwindow:::): Omit app icons and mini windows from the pager and task bar even when they are displayed at normal window level. 2010-12-11 Fred Kiefer * Source/winlib/WIN32GState.m: Remove a few compiler warnings. 2010-12-11 Fred Kiefer * Source/winlib/WIN32GState.m (GSCreateBitmap, -DPSImage:::...:): Better error detection. 2010-12-08 Jonathan Gillaspie * Source/win32/WIN32Server.m: Added better logging on Window create and destroy errors. Added a secondary call to get current mouse position if the first call fails. * Source/win32/w32_text_focus.m: Cast parameter to appropriate (HWND) type. 2010-11-18 Eric Wasylishen * Source/winlib/WIN32FontInfo.m: * Source/winlib/WIN32GState.m: * Source/cairo/CairoFontInfo.m: * Source/cairo/CairoGState.m: * Source/win32/w32_general.m: * Source/win32/w32_create.m: * Source/x11/XGServerWindow.m: * Source/gsc/GSGState.m: Replace objc_malloc with malloc and objc_free with free 2010-09-11 Fred Kiefer * Source/x11/convert.c (image2StandardPseudoColor): Small change to keep static code analyser happy. * Source/x11/XGServerEvent.m (process_key_event): Don't process the event if we don't have a key window. * Source/x11/XGServerWindow.m (_computeDepth): Test for unknown visual class. * Tools/gpbs.m: Rename newDataWithVersion: into dataWithVersion to follwo the Objective_c naming convention. 2010-09-10 Eric Wasylishen * Source/win32/w32_activate.m: Revert the change to call -[NSApp deactivate].. more investigation needed 2010-08-30 Eric Wasylishen * Source/win32/WIN32Server.m: Only show taskbar buttons for windows which satisfy both: - style mask isn't NSBorderlessWindowMask - style mask don't have NSUtilityWindowMask set Should fix bug 30911 2010-08-29 Eric Wasylishen * Source/win32/w32_activate.m: Call -[NSApp deactivate] in response to a WM_ACTIVEAPPP message reporting that the app lost focus. This delivers NSApplicationWillResignActiveNotification and NSApplicationDidResignActiveNotification, hides panels, etc. 2010-08-24 Eric Wasylishen * Source/win32/WIN32Server.m: Handle Page Down and Page Up keys, as well as adding a few others. 2010-08-24 Eric Wasylishen * Headers/win32/WIN32Server.h: * Source/win32/WIN32Server.m: * Source/win32/w32_movesize.m: Fix a rather serious error where the extra window data was allocated in two places (allocated with objc_malloc in the WM_CREATE handler, and also allocated by Windows using the cbWndExtra field of the window class structure). Sometimes the window level was accessed from one memory area and sometimes from the other. This is a quick fix that leaves the level and ordered properties in the cbWndExtra area, and the rest is left in the WIN_INTERN structure. This fixes the problem where window ordering was broken when running apps in gdb. 2010-08-24 Eric Wasylishen * Source/win32/WIN32Server.m (-setmaxsize::): Remove the maximize box when a maximum size is set on a window. 2010-08-10 Fred Kiefer * Source/cairo/CairoFontEnumerator.m, * Source/xlib/GSXftFontInfo.m: Also request spacing information. Patch by Derek Fawcus . 2010-08-03 Eric Wasylishen * Source/win32/WIN32Server.m: Only look at NSUtilityWindowMask to decide whether to use a thin- style title bar (WS_EX_TOOLWINDOW). 2010-07-28 Fred Kiefer * Source/gsc/GSGState.m (-fillRect:withPattern:): Don't use an autoreleased bezier path. * Source/art/path.m (-DPSrectfill::::), * Source/xlib/XGGState.m (-DPSrectfill::::): Use -fillPath:withPattern: not -fillRect:withPattern: as the rect needs to be converted first. 2010-07-26 Fred Kiefer * Source/win32/WIN32Server.m, * Source/x11/XGServerEvent.m: Use NSDeleteCharacter instead of NSBackSpaceCharacter for the backspace key. This is what Cocoa and OpenStep have been doing all the time. Also use NSBackTabCharacter on X11 when XK_ISO_Left_Tab is pressed, but don't convert shift-tab into NSBackTabCharacter. Patch by Derek Fawcus . 2010-07-25 Eric Wasylishen * Source/win32/WIN32Server.m: Fix accidental integer division intended to be float division when setting the timestamp on events. This was causing all timestamps to be rounded to the nearest second. 2010-07-25 Eric Wasylishen * Source/win32/w32_GLContext.m: * Source/x11/XGGLContext.m: Apply fix for bug 29705: OpenGL subwindow positioning error (OpenGL subwindow position was incorrectly calculated when the window content view was flipped) 2010-07-25 Fred Kiefer * Source/x11/XGServerEvent.m: Treat Shift modifiers in the same manner as other modifiers. This fixes the value of the shift bit (NSShiftKeyMask) in the modifierFlags passed to a -flagsChanged: method call. Without it the shift bit is inverted, as explained in the source comments, as X reports the modifier bits in force before the key was pressed/released. Patch by Derek Fawcus . 2010-07-25 Eric Wasylishen * Source/win32/WIN32Server.m: When ordering out a window, use the SWP_NOACTIVATE flag on SetWindowPos so Windows doesn't activate/deactivate any windows when hiding a window. This fixes the bug where when a tooltip disappeared, it would deactivate the window the tooltip was over. 2010-07-07 Eric Wasylishen * Source/win32/WIN32Server.m: * Source/win32/w32_movesize.m: Fix for bug #29709: Windows: Maximize button in a window title bar is always grayed out 2010-07-06 Eric Wasylishen * Source/win32/WIN32Server.m: Tweak the conditions for incrementing the clickCount when handling mouse clicks: (i.e. double click detection) - Require a click to be within a distance (retrieved from Windows) of the last click to count (previously there was no proximity check) - Allow clicks separated by the Windows double click time interval to count (e.g. if the Windows double click time interval is n, clicking at times 0, n, 2n, 3n would produce events with click counts 1, 2, 3, and 4. This matches OS X behaviour. Previously, all clicks had to be within the windows double click time interval to count as one group.) 2010-06-23 Quentin Mathe Fixed Windows backend issues introduced with r30523 where images are drawn at the wrong location by -[NSImage drawXXX] methods. See bug report #30069 Images are also now drawn correctly with these methods in a rotated/scaled context unlike previously (but alpha blending still doesn't work properly). * Source/winlib/WIN32Context.m (-supportsDrawGState): Added. * Headers/winlib/WIN32GState.m: Added oldWorldTransform ivar. * Source/winlib/WIN32GState.m: (-setUpAppKitBaseCoordinatesForHDC:, -restoreGDIBaseCoordinatesForHDC:, drawGState:fromRect:toPoint:op:fraction:): Added. 2010-06-06 Fred Kiefer * Source/cairo/CairoGState.m (-compositeGState:fromRect:toPoint:op:fraction:): Move the usage of _ct and source->_ct after the check whether they are set. 2010-06-01 Quentin Mathe Fixed composite operator to behave correctly and added a new draw operator to get -[NSImage drawXXX] methods work exactly as Cocoa and improve the drawing performance in some cases. Eliminated all flipping checks in the backend to ensure the flipping remains an high-level AppKit concept. * Source/gsc/GSContext.m: (-GSdraw:toPoint:fromRect:operation:fraction:): Added. This method calls -drawGState:fromRect:toPoint:op:fraction:. * Headers/gsc/GSGState.h (-drawGState:fromRect:toPoint:op:): Added as an informal protocol which can be implemented by subclasses * Source/cairo/CairoContext.m (-supportsDrawGState): Added overriden implementation that enables -drawGState:fromRect:toPoint:op:fraction:. * Source/cairo/CairoGState.m: (-drawOrientationMarkersIn:): Added. (-DPSimage::::::): Removed flipping check. (-compositeGState:fromRect:toPoint:op:fraction:): Fixed to precisely implement the PostScript behavior which is to ignore rotation and scaling effect for the content but not for the destination point. Also documented in details since this code is complex. (-drawGState:fromRect:toPoint:op:fraction:): Added. 2010-05-25 Riccardo Mottola * Source/x11/XGDragView.m * Source/gsc/GSGState.m Added missing imports. 2010-05-16 17:39-EDT Gregory John Casamento * Headers/win32/WIN32Server.h * Source/win32/w32_general.m * Source/win32/WIN32Server.m: Added code to re-activate the theme when the theme changes on Windows. 2010-05-11 Fred Kiefer * configure.ac: Make cairo the default backend. Fall back to art and xlib gracefully. * configure: Regenerate. 2010-05-10 Adam Fedor * Fix release documentation 2010-05-09 Adam Fedor * Version 0.19.0 Unstable release 2010-05-09 Adam Fedor * Version 0.18.0 2010-04-20 Doug Simons * Source/winlib/WIN32GState.m: Fix problem with display location for some composited images. 2010-04-20 Doug Simons * Source/win32/WIN32Server.m: Fix problem with key events going to window other than the key window. Block callbacks while setting the foreground window to prevent key/main window changes from cascading in a feedback loop. 2010-04-18 Eric Wasylishen * Source/winlib/WIN32FontInfo.m: Use DEFAULT_QUALITY for fonts instead of ANTIALISED_QUALITY. ANTIALISED_QUALITY forces small text to be non-antialised, which looks out of place compared with most Windows apps. 2010-04-15 Eric Wasylishen * Source/win32/w32_create.m: Use the default icon size when loading the app ico file Otherwise, the first icon in the file would be used. 2010-04-14 Jonathan Gillaspie * Source/win32/WIN32Server.m: Have non-key, non-main windows that order front not become active. Also don't bring windows that are ordering out to the foreground first. 2010-03-25 Fred Kiefer * Source/art/ftfont.m, * Source/art/ftfont-old.m, * Source/xlib/XGGState.m: Add more missing imports. 2010-03-25 Riccardo Mottola * Source/gsc/GSGState.m: import NSValue, include -> import * Source/xlib/XGGState.m: added missing imports 2010-03-24 Doug Simons * Source/winlib/WIN32FontInfo.m: Include NSDebug.h for definition of NSDebugLLog(). 2010-03-24 Doug Simons * Source/win32/WIN32Server.m: Ignore duplicate mouse down events generated by first click in a window. 2010-03-19 Eric Wasylishen * Headers/win32/w32_movesize.h: * Source/win32/w32_movesize.m: * Source/win32/WIN32Server.m: Call displayIfNeeded on the window when WM_SIZING is recieved so windows redraw while being resized. 2010-03-19 Eric Wasylishen * Source/win32/WIN32Server.m: Report deltaX and deltaY for mouse move events, like OS X does. 2010-03-19 Eric Wasylishen * Source/win32/WIN32Server.m: Process WM_SYSKEYDOWN and WM_SYSKEYUP messages - these are delivered instead of normal WM_KEYDOWN and WM_KEYUP messages when the ALT key is presesd. (and also F10). This fixes NSAlternateKeyMask not being set. 2010-03-13 Eric Wasylishen * Source/win32/w32_GLcontext.m: Set the WS_DISABLED flag on the OpenGL subwindow so mouse/keyboard events get redirected to the parent window. Previously mouse/keyboard events were being eaten by the OpenGL subwindow - now they work as expected. 2010-03-13 Eric Wasylishen * Source/win32/w32_GLcontext.m: Make more than one NSOpenGLView in an application work.

Defaults Summary

This document contains a summary of available user default values that one can set to control the operation of the GNUstep backend.

Backend Defaults

Below is a list of defaults used to control the x11-based backend. These defaults generally control system specific display and user interaction options which may not be available on all systems.

NSDefaultVisual

An integer that specifies the X-Windows visual class to use in the application. For instance one could display the application using the PsuedoColor visual class by setting the value to the id of this class. The default is the X-Windows default visual class.

NSColorsPerChannel

An integer which limits the maximum number of colors to display, per channel. For a psuedo-color display, this would limit the total number of colors that the application could use (normally 256). For a true-color display, this would limit the range of red, green, and blue values that could be used.

GSAppOwnsMiniwindow

GSAppOwnsMiniwindow is for miniwindows (not app icons). If it's YES or absent, GNUstep handles miniaturization itself and doesn't let the window manager do it. If it's NO, the window manager is allowed to do its own iconification. This does not affect app icons at all.

GSFontAntiAlias

With the xlib backend, this is a boolean value which defaults to YES. If set to YES and X Windows system has the XFT extension, then the application will use anti-aliased fonts as provided by XFT. If set to NO anti-aliased fonts will not be used even when available.

With the art backend, A boolean value which defaults to YES. If YES, text is anti-aliased at small sizes (9-16 pixels). The value is advisory (specific fonts can override this setting).

GSFontMask

[Xlib backend only] A string value which defaults to "*". It defines the pattern used to get the installed fonts from the X-Server. A value of "*-iso8859-1" would only include fonts available with ISO Western encoding. This feature might be helpfull if the font_cacher program is having problem with the X-Server.

GSBackHandlesWindowDecorations

A boolean value, which indicates if the backend should let the window-manager/native-window-system handle window decorations. When set to NO, GNUstep-GUI will handle the window decorations, which is particularly useful if you aren't running any window manager.

GSUseWMTaskBar

[W32 backend only] A string value which defaults to YES. If enabled, the backend assumes that miniwindows are displayed in a task bar. In this case, the app icon is not shown and the main menu behavior is changed so it is not ordered out, but minimized, so clicking on the minimized menu will activate the application.

GSXEnableFontSet

A string value which defaults to NO. If set to YES, then the backend font classes will support full multi-byte/unicode characters. This is useful for using many East Asian languages. However, the respose of the GUI is somwhat slower when this is enabled.

GSXIMInputMethodStyle

A string value used to specify the XIM input method for entering characters. Valid values are RootWindow, OffTheSpot, or OverTheSpot.

GraphicCompositing

[Xlib backend only] A boolean value which defaults to YES. If set to YES, then the application uses various tricks to get alpha colors to work when compositing images. This may slow down drawing of images, but it is generally recommended anyway, particularly on fast systems.

Fast Drawing on 8-bit Displays

[X11-based backends only] This is not a user default, but if you are using an 8-bit display and you define the standard X11 BEST colormap (via xstdcmap -best), then GNUstep will use this colormap and enable faster drawing onto 8-bit displays.

Keyboard Modifiers

The OPENstep specification requires three main different keyboard modifiers: CONTROL, COMMAND and ALTERNATE as well as the HELP modifier for context help. Some systems may not have these set up correctly. You can changed the defaults with the default keys.

GSFirstControlKey GSSecondControlKey GSFirstCommandKey GSSecondCommandKey GSFirstAlternateKey GSSecondAlternateKey GSFirstHelpKey GSSecondHelpKey

Default values are respectively:

Control_L Control_R Alt_L NoSymbol Alt_R NoSymbol Help Super_L

These strings correspond to "keysyms" on X11 systems. On X11, physical keys on the keyboard are equivalent to keycodes. A single keysym may be associated to more than one keycode, and can even be associated to a shifted key.

This is described more completely in the GUI documentation on keyboard setup.

GSModifiersAreNotKeys

On some keyboards, the default X11 mapping includes keycodes that are mapped to one or another modifier keysym depending on whether 'shift' (or in some cases, another key) is pressed. This is the case on some Apple USB keyboards for example: one key to the left of the spacebar maps to "Option" without shift pressed, and "Alt" with shift pressed. Such keyboard mappings are often useful in non-English contexts to access accents or non-Roman characters. However if such a key is used as a modifier in GNUstep problems can occur when trying to use the modifier in conjunction with a shifted character. In particular, you will need to hit and release the modifier and the shift key in a particular order, or else things will not work as expected, and the modifier may become "stuck".

Previously this default was called GSModifiersAreKeys, and Shift+Alt key equivalents only worked if Shift and Alt were pressed in the right order, unless the default was set to YES. That is now the default; to get back the previous default behaviour, set GSModifiersAreNotKeys to YES.

UseWindowMakerIcons

UseWindowMakerIcons is for app icons, and has no effect when the window manager isn't Window Maker. It displays the application's icon window in the window Window Maker provides instead of creating one controlled by the app. This allows the icon to be docked. It is a boolean value which defaults to YES.

XGPS-Shm

A boolean value which defaults to YES (as long as shared memory is available). If set to NO, shared memory is not used for various display specific operations.

GSOldClipboard

[X backends only] A boolean value which defaults to NO. If set to YES the old GNUstep way of X clipboard interaction will be used. That is PRIMARY as the general pasteboard and CLIPBOARD for the selection. Whereas the new X standard is the other way around. This setting may be needed for interaction in an old X enviornment.

Window Focus

This document describes how various events and user actions affect window focus of GNUstep applications. This document for the most part describes focus changes that occur outside of application control, since application window focus changes are well described in the class documentation.

Application Focus

The application can get focus in several ways:

Launch from the command line or another app Another app looses focus (e.g. by terminating) The user switches screens to the one the app is displayed on Double-click on the application icon

The first case does not directly affect window focus (because there are no windows at startup). However, as the application begins to create and order front windows (including the main menu) there will likely be a cascade of focus events generated by the window manager for each window ordered in.

In the second and third case, the window manager will likely try to give focus to the window that previously had it or perhaps to some random window based on some internal window manager code. GNUstep may ignore this request and try to give focus to another window, typically the application's idea of the current key window.

The last case is handled in the GUI front-end.

KeyboardFocus

The Key window is the window that has keyboard focus and has keyboard events sent to it. When an application receives focus, the window manager will typically ask one window to take keyboard focus (see above, Application Focus).

When an application is launched, in many cases, only the application icon and main menu may be displayed. In the OpenStep interface, neither of these is really supposed to be a key window, and in fact, many window managers control the application icon so this cannot be made key anyway. In X-Windows, however, there is no other way for an application to receive keyboard events unless a visible window has been made key. This leaves the main menu.

When an application receives focus, or if all the windows in an application are closed (see the private method [NSWindow-_lossOfKeyOrMainWindow]), then the main menu will request keyboard focus (see below).

The GUI front-end may function differently to accomadate different window manager behavior. Below is a list of the changes the front-end makes for different managers and windowing systems:

WindowMaker

WindowMaker controls the application icon so it cannot receive keyboard events. The main menu is made key if there is no other window capable of becoming key.

Requesting Keyboard Focus

A window may request to get keyboard focus in serveral instances. The window requests keyboard focus through the server method -setinputfocus::

If the window asks or is asked to become key, through the [NSWindow-becomeKeyWindow] method If the window is ordered front and the window is the key window. If during _lossOfKeyOrMainWindow, only the main menu is able to become key (for window systems where this is required).
Window Focus In/Out

The GUI front-end receives two types of focus events from the back-end (through an NSEvent object). Both of these are subsets of the NSAppKitDefined event: GSAppKitWindowFocusIn and GSAppKitWindowFocusOut. A FocusIn event can be received for several reasons:

The window manager deminiaturized the window. The WM should really tell the application to do this itself, but many WMs don't. In this case the window just posts a notification that it happened. The application is in the process of hidding. As each window is ordered out, the WM may send a focus message (spuriously) to the next window in line. In this case the message is just ignored. If the previous cases do not apply, the window checks if it can become key or main and activates the application if it is not active. If this window is the main menu, it looks for another window to become the key window, if possible, through the _lossOfKeyOrMainWindow mechanism

The back-end should keep track of the last window that requested to become key. This can be important in determining whether the back-end should send a FocusIn event to a window when it receives a signal from the window manager or windowing system. Sending a FocusIn event to a window that already requested it, may cause focus confusion in the GUI.

The front-end does nothing for FocusOut messages.

X-Windows messages

This section describes messages that X-Windows servers and the WM generally send to the application. Other window servers may send similar messages.

Take Focus

A message from the WM telling a window it should take keyboard focus. If the app is not active, the back-end should send a FocusIn event. Otherwise, the back-end should only send a FocusIn event to the front end if the message is due to a user action, such as a click on the title bar (i.e. the target window is not the current key window or the last window that requested key status). The back-end may also send an event if the window has just been mapped, although this is not typically necessary, unless it's due to a screen change.

In other cases, the back-end should do what is necessary to make sure that the last window to request key status receives it instead of the one the WM thinks should receive it.

Focus In

A message from the server telling the application that keyboard focus has been set for a window. The back-end should not send an event to the front-end in this case. However, the back-end should use this information to determine when to send a message in other cases (e.g. from a Take Focus message).

Focus Out

A message from the server telling the application that focus has left a window. If the focus has gone to a window that is not part of the application, the back-end should tell the NSApp to deactivate. Otherwise it should do nothing.

It is a back-end component for the GNUstep GUI Library. The implementation of the GNUstep GUI Library is designed in two parts. The first part is the front-end component which is independent of platform and display system. This front-end is combined with a back-end component which handles all of the display system dependent such as specific calls to the X Window System. This design allows the GNUstep applications to have the "look and feel" of the underlying display system without any changes to the application, and the library can be easily ported to other display systems. The GNUstep GUI Backend is for platforms using the X-Window System or Window's Systems. It works via a DPS emulation engine to emulate the DPS functions required by the front-end system. @set ANNOUNCE-ONLY @include news.texi @clear ANNOUNCE-ONLY @section Where can you get it?

If you are installing this package as part of the GNUstep core package, read the file GNUstep-HOWTO for more complete instructions on how to install the entire GNUstep package (including this library). GNUstep-HOWTO is located at @url{http://www.gnustep.org} You must have installed gnustep-gui before installing this library. @node Configuration, Compilation, Introduction, Top @section Configuration Configuration is performed by running the @file{configure} program at a shell prompt. You may want to use some of the optional arguments to the @file{configure} program. Type @code{configure --help} for a list. GNUstep specific options are at the end of this list (if any). The backend comes with several different window server and graphics drawing implementations. If you do nothing, the default ones will be chosen. You can can change this using configure. For instance, to choose the art graphical drawing implementation, run @example configure --enable-graphics=art @end example Type @code{configure --help} for a list of graphical drawing implementations. You can also change the name of the backend when configuring it. This is convienient if you want to have a different backend with different configurations. For instance, to create an xlib and and art backend, you could do this: @example configure --enable-graphics=xlib --with-name=xlib make install make distclean configure --enable-graphics=art --with-name=art make install @end example Before running an application, choose one backend using the defaults program: @example defaults write NSGlobalDomain GSBackend libgnustep-xlib @end example @node Compilation, Installing, Configuration, Top @section Compilation To compile this library, type make. After this is complete, type make install (make sure you are the root user). Some additional options you can use with make are @samp{debug=yes} to make a debugging version of the library and @samp{shared=no} to make a static version of the library.

Hence, when gstate is switched, it's OpalContext's duty to apply the stored copy of a gstate from _opGState.

If you are installing this package as part of the GNUstep core package, read the file GNUstep-HOWTO for more complete instructions on how to install the entire GNUstep package (including this library). GNUstep-HOWTO is located at `http://www.gnustep.org' You must have installed gnustep-gui before installing this library. 1.2 Configuration ================= Configuration is performed by running the `configure' program at a shell prompt. You may want to use some of the optional arguments to the `configure' program. Type `configure --help' for a list. GNUstep specific options are at the end of this list (if any). The backend comes with several different window server and graphics drawing implementations. If you do nothing, the default ones will be chosen. You can can change this using configure. For instance, to choose the art graphical drawing implementation, run configure --enable-graphics=art Type `configure --help' for a list of graphical drawing implementations. You can also change the name of the backend when configuring it. This is convienient if you want to have a different backend with different configurations. For instance, to create an xlib and and art backend, you could do this: configure --enable-graphics=xlib --with-name=xlib make install make distclean configure --enable-graphics=art --with-name=art make install Before running an application, choose one backend using the defaults program: defaults write NSGlobalDomain GSBackend libgnustep-xlib 1.3 Compilation =============== To compile this library, type make. After this is complete, type make install (make sure you are the root user). Some additional options you can use with make are `debug=yes' to make a debugging version of the library and `shared=no' to make a static version of the library. See the gstep-make package for more information on these options. 1.4 Installing ============== To install, type make install gnustep-back-0.25.0/NEWS000066400000000000000000000220401273700670400146640ustar00rootroot000000000000001 NEWS ****** 1.1 Noteworthy changes in version `0.25.0' ========================================== Implement per gstate methods for antialias, patternPhase and compositingOperation in Cairo backend. Work on antialiasing in Cairo backend.

Fixed drawing and flipping (goes along with gui change). More Windows improvements. 1.7 Noteworthy changes in version `0.19.0' ========================================== This is an (unstable) copy of the 0.18.0 release 1.8 Noteworthy changes in version `0.18.0' ========================================== Many Windows improvements Implement pattern colours for all backends. 1.9 Noteworthy changes in version `0.17.1' ========================================== Use DejaVu as another fallback font. 1.10 Noteworthy changes in version `0.17.0' ========================================== Key repeat support implemented in X11. OpenGL fixes and improvements. 1.11 Noteworthy changes in version `0.16.0' =========================================== Transparent windows implemented in WIN32 backend, better position and scaling of images. General cleanup of code. 1.12 Noteworthy changes in version `0.14.0' =========================================== Added code to automatically make any window which uses the NSDesktopWindowLevel also be omnipresent. Many glyph drawing improvements. 1.13 Noteworthy changes in version `0.13.2' =========================================== Added basic implementation of window levels on Windows. In general a bunch of improvements in the Windows backend. Experimental patch for using cairo on Windows. More support for RTF, TIFF and selctions in the pasteboard server. There has been change in the interaction of devices with the gui frontend. This version or greater of the backend needs to be used with gui 0.13.2 1.14 Noteworthy changes in version `0.13.1' =========================================== Minor improvements. 1.15 Noteworthy changes in version `0.13.0' =========================================== Many improvements to the cairo backend. Add DPSshfill for all backends. Better handling of X event times. 1.16 Noteworthy changes in version `0.12.0' =========================================== Big improvements to the cairo graphics and Window backend. Also better support for OpenGL. 1.17 Noteworthy changes in version `0.11.0' =========================================== Bugfixes to art and xlib. There was some work on the Windows backend for the GDI interface by Christopher Armstrong. 1.18 Noteworthy changes in version `0.10.3' =========================================== Fixes. A lot of Cairo backend work. 1.19 Noteworthy changes in version `0.10.2' =========================================== The Backend can set UTF8 window titles where this is allowed. 1.20 Noteworthy changes in version `0.10.1' =========================================== The art graphics module is the default now. As was previously the case, if the proper libraries are not found, the configuration will automatically switch to xlib on winlib (whichever is appropriate). There was a great deal of work by Tom MacSween on the windows module to get windows and taskbars working together, closing, opening, hiding, and just general good window management. The Cairo module has been significantly updated and now works with Cariro version 1.0, although you need to make some minor changes to the Cairo library before it will work with GNUstep. Due to this, this module is still considered beta. Ask on the mailing lists for help with this. 1.21 Noteworthy changes in version `0.10.0' =========================================== The installed name of the backend now includes an interface version number. This avoids the potential version mismatch between the frontend (GUI) library and the backend. * Alpha blending was implemented for Windows, although it does not seem to work on some machines. 1.22 Noteworthy changes in version `0.9.5' ========================================== * Added support for window alpha on X servers. * Add support for old and new freetype libs. * Some improvements to the Windows backend. 1.23 Noteworthy changes in version `0.9.4' ========================================== * Fast drawing on 8 bit displays was added (although it might only speed things up on old X11 servers and/or remote servers). * GNUstep modifier keys are mapped to KeySyms instead of KeyCodes * Added a Cairo backend, although it is probably non-functional. Anyone is invited to contribute to making it work. * art backend supports reading from a window. * Add internal window decoration handling. 1.24 Noteworthy changes in version `0.9.3' ========================================== * A number of W32 window event enhancements * art backend glyph drawing with alpha enhancements. * libwraster is no longer checked for - image functions now in frontend 1.25 Noteworthy changes in version `0.9.2' ========================================== * Art backend added support for grayscale, one-isblack colorspaces. * Windows pasteboard interaction handling added. * Better focus handling on Windows. * Better font and draw handling on Windows. 1.26 Noteworthy changes in version `0.9.1' ========================================== Color on 8 bit displays works correctly now.

Add -with-library-flags and -with-include-flags for adding additonal flags. Set name with -with-name 1.39 Noteworthy changes in version `0.7.7' ========================================== First release. Most components extracted from xgps. The old backends, xgps and xdps were depreciated in favor of this new backend, simply named back, which can be configured for a variety of window server and graphics implementations, and also allow for improved code sharing. In addition there is now a window server backend for Windows computers, although it is in a very alpha state. gnustep-back-0.25.0/README000066400000000000000000000011661273700670400150530ustar00rootroot000000000000001 README ******** This is version 0.25.0 of the GNUstep GUI Backend (`gnustep-back').

It is possible to do the transform _after_ step 5 (although it's less efficient), but we want to do any curve approximation (3, and 5 if there are round line ends or joins) in device space. The best way to solve this is probably to keep doing the transform first, and to add transform-aware dashing and stroking functions to libart.

This class is a reasonable attempt at providing PostScript-like drawing operations. Don't even begin to think that this is a full PostScript implementation, however. Only operations that do not require stack handling are implemented. Some other functions that would require stack handling and are needed for drawing are implemented in a different way (e.g. colorspace and images). These functions should also allow for a reasonable simulation of Quartz functionality.

The program can be used as is by making a procedure call to ** parse an AFM file and have the data stored, or an application developer ** may wish to customize the code. ** ** This header file defines the data structures used as well as the key ** strings that are currently recognized by this version of the AFM parser. ** This program is based on the document "Adobe Font Metrics Files, ** Specification Version 2.0". ** ** AFM files are separated into distinct sections of different data. Because ** of this, the parseAFM program can parse a specified file to only save ** certain sections of information based on the application's needs. A record ** containing the requested information will be returned to the application. ** ** AFM files are divided into five sections of data: ** 1) The Global Font Information ** 2) The Character Metrics Information ** 3) The Track Kerning Data ** 4) The Pair-Wise Kerning Data ** 5) The Composite Character Data ** ** Basically, the application can request any of these sections independent ** of what other sections are requested. In addition, in recognizing that ** many applications will want ONLY the x-width of characters and not all ** of the other character metrics information, there is a way to receive ** only the width information so as not to pay the storage cost for the ** unwanted data. An application should never request both the ** "quick and dirty" char metrics (widths only) and the Character Metrics ** Information since the Character Metrics Information will contain all ** of the character widths as well. ** ** There is a procedure in parseAFM.c, called parseFile, that can be ** called from any application wishing to get information from the AFM File. ** This procedure expects 3 parameters: a vaild file descriptor, a pointer ** to a (AFMFontInfo *) variable (for which space will be allocated and then ** will be filled in with the data requested), and a mask specifying ** which data from the AFM File should be saved in the AFMFontInfo structure. ** ** The flags that can be used to set the appropriate mask are defined below. ** In addition, several commonly used masks have already been defined. ** ** History: ** original: DSM Thu Oct 20 17:39:59 PDT 1988 ** modified: DSM Mon Jul 3 14:17:50 PDT 1989 ** - added 'storageProblem' return code ** - fixed typos ** **************************************************************/ #include /* ** Flags that can be AND'ed together to specify exactly what ** information from the AFM file should be saved. */ #define AFM_G 0x01 /* 0000 0001 */ /* Global Font Info */ #define AFM_W 0x02 /* 0000 0010 */ /* Character Widths ONLY */ #define AFM_M 0x06 /* 0000 0110 */ /* All Char Metric Info */ #define AFM_P 0x08 /* 0000 1000 */ /* Pair Kerning Info */ #define AFM_T 0x10 /* 0001 0000 */ /* Track Kerning Info */ #define AFM_C 0x20 /* 0010 0000 */ /* Composite Char Info */ /* ** Commonly used flags */ #define AFM_GW (AFM_G | AFM_W) #define AFM_GM (AFM_G | AFM_M) #define AFM_GMP (AFM_G | AFM_M | AFM_P) #define AFM_GMK (AFM_G | AFM_M | AFM_P | AFM_T) #define AFM_ALL (AFM_G | AFM_M | AFM_P | AFM_T | AFM_C) /* ** Possible return codes from the AFMParseFile procedure. ** ** afm_ok means there were no problems parsing the file. ** ** afm_parseError means that there was some kind of parsing error, but the ** parser went on.

While .B gpbs will be started automatically as soon as it is needed, it is recommend to start .B gpbs in a personal login script like ~/.bashrc or ~/.cshrc. Alternatively you can launch gpbs when your windowing system or the window manager is started. For example, on systems with X11 you can launch .B gpbs from your .xinitrc script or alternatively - if you are running Window Maker - put it in Window Maker's autostart script. See the .I GNUstep Build Guide for a sample startup script. .P .SH OPTIONS .TP \fB\-NSHost\fR \fB\fR attaches \fBgpbs\fR to a remote session. .TP \fB\--GSStartupNotification\fR sends a notification through the NSDistributedNotificationCenter (i.e. gdnc) so that apps know that it has started up. This is only relevant if the application itself tries to startup \fBgpbs\fR (which means \fBgpbs\fR was not started at session login). .TP \fB\--daemon\fR starts \fBgpbs\fR as a daemon - mostly this means that all output gets sent to syslog rather than the terminal. .TP \fB\--no-fork\fR does not fork a separate process .TP \fB\--verbose\fR makes \fB\gpbs\fR his logging more verbose .SH DIAGNOSTICS .B gdomap -L GNUstepGSPasteboardServer will lookup instances of .B gpbs. .P Alternatively, .B gdomap -N will list all registered names on the local host. .P .SH BUGS Versions of .B gpbs up to (including) 1.7.2 have problems with copy and paste of mulit-lingual text, as it used the atom XA_STRING alone to exchange string data between X clients (and thus GNUstep clients). This means .B gpbs is inherently unable to do cut-and-paste with characters other than ISO Latin1 ones, TAB, and NEWLINE. .P .SH SEE ALSO gdnc(1), gdomap(8), GNUstep(7) xinit(1) wmaker(1) .P .I The GNUstep Build Guide example startup script: .P .SH HISTORY Work on .B gdnc started August 1997. .PP This manual page first appeared in gnustep-back 0.8.8 (July 2003). .P .SH AUTHORS gpbs was written by Richard Frith-McDonald .P This man page was written by Martin Brecher with contributions from Kazunobu Kuriyama . .P This man page was updated September 2006 by Dennis Leeuw (dleeuw@made-it.com) with notes by Adam Fedor (fedor@doc.com). gnustep-back-0.25.0/Tools/gpbs.m000066400000000000000000000705041273700670400164060ustar00rootroot00000000000000/* gpbs.m GNUstep pasteboard server Copyright (C) 1997,1999 Free Software Foundation, Inc.
