b/ABOUT-NLS @@ -0,0 +1,1410 @@ +1 Notes on the Free Translation Project +*************************************** + +Free software is going international! The Free Translation Project is +a way to get maintainers of free software, translators, and users all +together, so that free software will gradually become able to speak many +languages. A few packages already provide translations for their +messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work on translations can contact the appropriate team. + +1.1 INSTALL Matters +=================== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU `gettext'. Other packages have their own ways to +internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. Installers may use special +options at configuration time for changing the default behaviour. The +command: + + ./configure --disable-nls + +will _totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl' library +and will decide to use it. If not, you may have to to use the +`--with-libintl-prefix' option to tell `configure' where to look for it. + + Internationalized packages usually have many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +1.2 Using This Package +====================== + +As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. If you happen to have the `LC_ALL' or some other +`LC_xxx' environment variables set, you should unset them before +setting `LANG', otherwise the setting of `LANG' will not have the +desired effect. Here `LL' is an ISO 639 two-letter language code, and +`CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your language by running the +command `locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from `no' to `nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under `nb' and some older ones under `no', it's recommended +for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and +older translations are used. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +1.3 Translating Teams +===================== + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://translationproject.org/', in the "Teams" area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `coordinator@translationproject.org' to +reach the coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skills are praised more than +programming skills, here. + +1.4 Available Packages +====================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of June +2010. The matrix shows, in regard of each package, for which languages +PO files have been submitted to translation coordination, with a +translation percentage of at least 50%. + + Ready PO files af am an

Of course you have to respect the GNU Library General Public +License which covers the use of the GNU `gettext' library. This means +in particular that even non-free programs can use `libintl' as a shared +library, whereas only free software can use `libintl' as a static +library or use modified versions of `libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of `gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project. Contact +`coordinator@translationproject.org' to make the `.pot' files available +to the translation teams. + diff --git a/COPYING b/COPYING new file mode 100644 index 0000000..d159169 --- /dev/null +++ b/COPYING @@ -0,0 +1,339 @@ + GNU GENERAL PUBLIC LICENSE + Version 2, June 1991 + + Copyright (C) 1989, 1991 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. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) 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 +this service 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 make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. 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. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +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 Program or any portion +of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +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 Program, 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 Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) 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; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, 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 executable. However, as a +special exception, the source code 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. + +If distribution of executable or 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 counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program 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. + + 5. 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 Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program 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 to +this License. + + 7. 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 Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program 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 Program. + +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. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program 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. + + 9. The Free Software Foundation may publish revised and/or new versions +of the 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 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 Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, 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 + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

Basically any actor can be focused using + * clutter_stage_set_key_focus. So, we will use this approach: all actors are + * focusable, and we get the currently focused using clutter_stage_get_key_focus + * This affects focus related stateset and some atk_componenet focus methods (like + * grab focus). + * + * In the same way, we will manage the focus state change management + * on the cally-stage object. The reason is avoid missing a focus + * state change event if the object is focused just before the + * accessibility object being created. + * + * #AtkAction implementation: on previous releases ClutterActor added + * the actions "press", "release" and "click", as at that time some + * general-purpose actors like textures were directly used as buttons. + * + * But now, new toolkits appeared, providing high-level widgets, like + * buttons. So in this environment, it doesn't make sense to keep + * adding them as default. + * + * Anyway, current implementation of AtkAction is done at CallyActor + * providing methods to add and remove actions. This is based on the + * one used at gailcell, and proposed as a change on #AtkAction + * interface: + * + * https://bugzilla.gnome.org/show_bug.cgi?id=649804 + * + */ + +#ifdef HAVE_CONFIG_H +#include "clutter-build-config.h" +#endif + +#include +#include + +#ifdef CLUTTER_WINDOWING_X11 +#include +#endif + +#include + +#include "cally-actor.h" +#include "cally-actor-private.h" + +typedef struct _CallyActorActionInfo CallyActorActionInfo;

The order in which the transformations are + * applied is decided by Clutter and it is the following: + * + * 1. translation by the origin of the #ClutterActor:allocation property + * 2. translation by the actor's #ClutterActor:z-position property + * 3. translation by the actor's #ClutterActor:pivot-point property + * 4. scaling by the #ClutterActor:scale-x and #ClutterActor:scale-y factors + * 5. rotation around the #ClutterActor:rotation-angle-x and #ClutterActor:rotation-center-x + * 6. rotation around the #ClutterActor:rotation-angle-y and #ClutterActor:rotation-center-y + * 7. rotation around the #ClutterActor:rotation-angle-z and #ClutterActor:rotation-center-z + * 8. negative translation by the #ClutterActor:anchor-x and #ClutterActor:anchor-y point. + * 9. negative translation by the actor's #ClutterActor:pivot-point + * + * ## Modifying an actor's geometry ## {#clutter-actor-geometry} + * + * Each actor has a bounding box, called #ClutterActor:allocation + * which is either set by its parent or explicitly through the + * clutter_actor_set_position() and clutter_actor_set_size() methods. + * Each actor also has an implicit preferred size. + * + * An actor’s preferred size can be defined by any subclass by + * overriding the #ClutterActorClass.get_preferred_width() and the + * #ClutterActorClass.get_preferred_height() virtual functions, or it can + * be explicitly set by using clutter_actor_set_width() and + * clutter_actor_set_height(). + * + * An actor’s position can be set explicitly by using + * clutter_actor_set_x() and clutter_actor_set_y(); the coordinates are + * relative to the origin of the actor’s parent. + * + * ## Managing actor children ## {#clutter-actor-children} + * + * Each actor can have multiple children, by calling + * clutter_actor_add_child() to add a new child actor, and + * clutter_actor_remove_child() to remove an existing child. #ClutterActor + * will hold a reference on each child actor, which will be released when + * the child is removed from its parent, or destroyed using + * clutter_actor_destroy(). + * + * |[ + * ClutterActor *actor = clutter_actor_new (); + * + * // set the bounding box of the actor + * clutter_actor_set_position (actor, 0, 0); + * clutter_actor_set_size (actor, 480, 640); + * + * // set the background color of the actor + * clutter_actor_set_background_color (actor, CLUTTER_COLOR_Orange); + * + * // set the bounding box of the child, relative to the parent + * ClutterActor *child = clutter_actor_new (); + * clutter_actor_set_position (child, 20, 20); + * clutter_actor_set_size (child, 80, 240); + * + * // set the background color of the child + * clutter_actor_set_background_color (child, CLUTTER_COLOR_Blue); + * + * // add the child to the actor + * clutter_actor_add_child (actor, child); + * ]| + * + * Children can be inserted at a given index, or above and below + * another child actor. The order of insertion determines the order of the + * children when iterating over them. Iterating over children is performed + * by using clutter_actor_get_first_child(), clutter_actor_get_previous_sibling(), + * clutter_actor_get_next_sibling(), and clutter_actor_get_last_child(). It is + * also possible to retrieve a list of children by using + * clutter_actor_get_children(), as well as retrieving a specific child at a + * given index by using clutter_actor_get_child_at_index(). + * + * If you need to track additions of children to a #ClutterActor, use + * the #ClutterContainer::actor-added signal; similarly, to track removals + * of children from a ClutterActor, use the #ClutterContainer::actor-removed + * signal. + * + * See [basic-actor.c](https://git.gnome.org/browse/clutter/tree/examples/basic-actor.c?h=clutter-1.18). + * + * ## Painting an actor ## {#clutter-actor-painting} + * + * There are three ways to paint an actor: + * + * - set a delegate #ClutterContent as the value for the #ClutterActor:content property of the actor + * - subclass #ClutterActor and override the #ClutterActorClass.paint_node() virtual function + * - subclass #ClutterActor and override the #ClutterActorClass.paint() virtual function. + * + * A #ClutterContent is a delegate object that takes over the painting + * operations of one, or more actors. The #ClutterContent painting will + * be performed on top of the #ClutterActor:background-color of the actor, + * and before calling the actor's own implementation of the + * #ClutterActorClass.paint_node() virtual function. + * + * |[ + * ClutterActor *actor = clutter_actor_new (); + * + * // set the bounding box + * clutter_actor_set_position (actor, 50, 50); + * clutter_actor_set_size (actor, 100, 100); + * + * // set the content; the image_content variable is set elsewhere + * clutter_actor_set_content (actor, image_content); + * ]| + * + * The #ClutterActorClass.paint_node() virtual function is invoked whenever + * an actor needs to be painted. The implementation of the virtual function + * must only paint the contents of the actor itself, and not the contents of + * its children, if the actor has any. + * + * The #ClutterPaintNode passed to the virtual function is the local root of + * the render tree; any node added to it will be rendered at the correct + * position, as defined by the actor's #ClutterActor:allocation. + * + * |[ + * static void + * my_actor_paint_node (ClutterActor *actor, + * ClutterPaintNode *root) + * { + * ClutterPaintNode *node; + * ClutterActorBox box; + * + * // where the content of the actor should be painted + * clutter_actor_get_allocation_box (actor, &box); + * + * // the cogl_texture variable is set elsewhere + * node = clutter_texture_node_new (cogl_texture, CLUTTER_COLOR_White, + * CLUTTER_SCALING_FILTER_TRILINEAR, + * CLUTTER_SCALING_FILTER_LINEAR); + * + * // paint the content of the node using the allocation + * clutter_paint_node_add_rectangle (node, &box); + * + * // add the node, and transfer ownership + * clutter_paint_node_add_child (root, node); + * clutter_paint_node_unref (node); + * } + * + * The #ClutterActorClass.paint() virtual function is invoked when the + * #ClutterActor::paint signal is emitted, and after the other signal + * handlers have been invoked. Overriding the paint virtual function + * gives total control to the paint sequence of the actor itself, + * including the children of the actor, if any. + * + * It is strongly discouraged to override the #ClutterActorClass.paint() + * virtual function, as well as connecting to the #ClutterActor::paint + * signal. These hooks into the paint sequence are considered legacy, and + * will be removed when the Clutter API changes. + * + * ## Handling events on an actor ## {#clutter-actor-event-handling} + * + * A #ClutterActor can receive and handle input device events, for + * instance pointer events and key events, as long as its + * #ClutterActor:reactive property is set to %TRUE. + * + * Once an actor has been determined to be the source of an event, + * Clutter will traverse the scene graph from the top-level actor towards the + * event source, emitting the #ClutterActor::captured-event signal on each + * ancestor until it reaches the source; this phase is also called + * the "capture" phase. If the event propagation was not stopped, the graph + * is walked backwards, from the source actor to the top-level, and the + * #ClutterActor::event signal is emitted, alongside eventual event-specific + * signals like #ClutterActor::button-press-event or #ClutterActor::motion-event; + * this phase is also called the "bubble" phase. + * + * At any point of the signal emission, signal handlers can stop the propagation + * through the scene graph by returning %CLUTTER_EVENT_STOP; otherwise, they can + * continue the propagation by returning %CLUTTER_EVENT_PROPAGATE. + * + * ## Animation ## {#clutter-actor-animation} + * + * Animation is a core concept of modern user interfaces; Clutter provides a + * complete and powerful animation framework that automatically tweens the + * actor's state without requiring direct, frame by frame manipulation from + * your application code. You have two models at your disposal: + * + * - an implicit animation model + * - an explicit animation model + * + * The implicit animation model of Clutter assumes that all the + * changes in an actor state should be gradual and asynchronous; Clutter + * will automatically transition an actor's property change between the + * current state and the desired one without manual intervention, if the + * property is defined to be animatable in its documentation. + * + * By default, in the 1.0 API series, the transition happens with a duration + * of zero milliseconds, and the implicit animation is an opt in feature to + * retain backwards compatibility. + * + * Implicit animations depend on the current easing state; in order to use + * the default easing state for an actor you should call the + * clutter_actor_save_easing_state() function: + * + * |[ + * // assume that the actor is currently positioned at (100, 100) + * + * // store the current easing state and reset the new easing state to + * // its default values + * clutter_actor_save_easing_state (actor); + * + * // change the actor's position + * clutter_actor_set_position (actor, 500, 500); + * + * // restore the previously saved easing state + * clutter_actor_restore_easing_state (actor); + * ]| + * + * The example above will trigger an implicit animation of the + * actor between its current position to a new position. + * + * Implicit animations use a default duration of 250 milliseconds, + * and a default easing mode of %CLUTTER_EASE_OUT_CUBIC, unless you call + * clutter_actor_set_easing_mode() and clutter_actor_set_easing_duration() + * after changing the easing state of the actor. + * + * It is possible to animate multiple properties of an actor + * at the same time, and you can animate multiple actors at the same + * time as well, for instance: + * + * |[ + * clutter_actor_save_easing_state (actor); + * + * // animate the actor's opacity and depth + * clutter_actor_set_opacity (actor, 0); + * clutter_actor_set_depth (actor, -100); + * + * clutter_actor_restore_easing_state (actor); + * + * clutter_actor_save_easing_state (another_actor); + * + * // animate another actor's opacity + * clutter_actor_set_opacity (another_actor, 255); + * clutter_actor_set_depth (another_actor, 100); + * + * clutter_actor_restore_easing_state (another_actor); + * ]| + * + * Changing the easing state will affect all the following property + * transitions, but will not affect existing transitions. + * + * It is important to note that if you modify the state on an + * animatable property while a transition is in flight, the transition's + * final value will be updated, as well as its duration and progress + * mode by using the current easing state; for instance, in the following + * example: + * + * |[ + * clutter_actor_save_easing_state (actor); + * clutter_actor_set_easing_duration (actor, 1000); + * clutter_actor_set_x (actor, 200); + * clutter_actor_restore_easing_state (actor); + * + * clutter_actor_save_easing_state (actor); + * clutter_actor_set_easing_duration (actor, 500); + * clutter_actor_set_x (actor, 100); + * clutter_actor_restore_easing_state (actor); + * ]| + * + * the first call to clutter_actor_set_x() will begin a transition + * of the #ClutterActor:x property from the current value to the value of + * 200 over a duration of one second; the second call to clutter_actor_set_x() + * will change the transition's final value to 100 and the duration to 500 + * milliseconds. + * + * It is possible to receive a notification of the completion of an + * implicit transition by using the #ClutterActor::transition-stopped + * signal, decorated with the name of the property. In case you want to + * know when all the currently in flight transitions are complete, use + * the #ClutterActor::transitions-completed signal instead. + * + * It is possible to retrieve the #ClutterTransition used by the + * animatable properties by using clutter_actor_get_transition() and using + * the property name as the transition name. + * + * The explicit animation model supported by Clutter requires that + * you create a #ClutterTransition object, and optionally set the initial + * and final values. The transition will not start unless you add it to the + * #ClutterActor. + * + * |[ + * ClutterTransition *transition; + * + * transition = clutter_property_transition_new ("opacity"); + * clutter_timeline_set_duration (CLUTTER_TIMELINE (transition), 3000); + * clutter_timeline_set_repeat_count (CLUTTER_TIMELINE (transition), 2); + * clutter_timeline_set_auto_reverse (CLUTTER_TIMELINE (transition), TRUE); + * clutter_transition_set_from (transition, G_TYPE_UINT, 255); + * clutter_transition_set_to (transition, G_TYPE_UINT, 0); + * + * clutter_actor_add_transition (actor, "animate-opacity", transition); + * ]| + * + * The example above will animate the #ClutterActor:opacity property + * of an actor between fully opaque and fully transparent, and back, over + * a span of 3 seconds. The animation does not begin until it is added to + * the actor. + * + * The explicit animation API applies to all #GObject properties, + * as well as the custom properties defined through the #ClutterAnimatable + * interface, regardless of whether they are defined as implicitly + * animatable or not. + * + * The explicit animation API should also be used when using custom + * animatable properties for #ClutterAction, #ClutterConstraint, and + * #ClutterEffect instances associated to an actor; see the section on + * custom animatable properties below for an example. + * + * Finally, explicit animations are useful for creating animations + * that run continuously, for instance: + * + * |[ + * // this animation will pulse the actor's opacity continuously + * ClutterTransition *transition; + * ClutterInterval *interval; + * + * transition = clutter_property_transition_new ("opacity"); + * + * // we want to animate the opacity between 0 and 255 + * clutter_transition_set_from (transition, G_TYPE_UINT, 0); + * clutter_transition_set_to (transition, G_TYPE_UINT, 255); + * + * // over a one second duration, running an infinite amount of times + * clutter_timeline_set_duration (CLUTTER_TIMELINE (transition), 1000); + * clutter_timeline_set_repeat_count (CLUTTER_TIMELINE (transition), -1); + * + * // we want to fade in and out, so we need to auto-reverse the transition + * clutter_timeline_set_auto_reverse (CLUTTER_TIMELINE (transition), TRUE); + * + * // and we want to use an easing function that eases both in and out + * clutter_timeline_set_progress_mode (CLUTTER_TIMELINE (transition), + * CLUTTER_EASE_IN_OUT_CUBIC); + * + * // add the transition to the desired actor to start it + * clutter_actor_add_transition (actor, "opacityAnimation", transition); + * ]| + * + * ## Implementing an actor ## {#clutter-actor-implementing} + * + * Careful consideration should be given when deciding to implement + * a #ClutterActor sub-class. It is generally recommended to implement a + * sub-class of #ClutterActor only for actors that should be used as leaf + * nodes of a scene graph. + * + * If your actor should be painted in a custom way, you should + * override the #ClutterActor::paint signal class handler. You can either + * opt to chain up to the parent class implementation or decide to fully + * override the default paint implementation; Clutter will set up the + * transformations and clip regions prior to emitting the #ClutterActor::paint + * signal. + * + * By overriding the #ClutterActorClass.get_preferred_width() and + * #ClutterActorClass.get_preferred_height() virtual functions it is + * possible to change or provide the preferred size of an actor; similarly, + * by overriding the #ClutterActorClass.allocate() virtual function it is + * possible to control the layout of the children of an actor. Make sure to + * always chain up to the parent implementation of the + * #ClutterActorClass.allocate() virtual function. + * + * In general, it is strongly encouraged to use delegation and composition + * instead of direct subclassing. + * + * ## ClutterActor custom properties for ClutterScript ## {#clutter-actor-custom-script} + * + * #ClutterActor defines a custom "rotation" property which allows a short-hand + * description of the rotations to be applied to an actor. + * + * The syntax of the "rotation" property is the following: + * + * |[ + * "rotation" : [ { "" : [ , [ ] ] } ] + * ]| + * + * where: + * + * - axis is the name of an enumeration value of type #ClutterRotateAxis + * - angle is a floating point value representing the rotation angle on the given axis in degrees + * - center-point is an optional array, and if present it must contain the center of rotation as described by two coordinates: + * - Y and Z for "x-axis" + * - X and Z for "y-axis" + * - X and Y for "z-axis". + * + * #ClutterActor also defines a scriptable "margin" property which follows the CSS "margin" shorthand. + * + * |[ + * // 4 values + * "margin" : [ top, right, bottom, left ] + * // 3 values + * "margin" : [ top, left/right, bottom ] + * // 2 values + * "margin" : [ top/bottom, left/right ] + * // 1 value + * "margin" : [ top/right/bottom/left ] + * ]| + * + * #ClutterActor will also parse every positional and dimensional + * property defined as a string through clutter_units_from_string(); you + * should read the documentation for the #ClutterUnits parser format for + * the valid units and syntax. + * + * ## Custom animatable properties + * + * #ClutterActor allows accessing properties of #ClutterAction, + * #ClutterEffect, and #ClutterConstraint instances associated to an actor + * instance for animation purposes. + * + * In order to access a specific #ClutterAction or a #ClutterConstraint + * property it is necessary to set the #ClutterActorMeta:name property on the + * given action or constraint. + * + * The property can be accessed using the following syntax: + * + * |[ + * @
.. + * ]| + * + * - the initial `@` is mandatory + * - the `section` fragment can be one between "actions", "constraints" and "effects" + * - the `meta-name` fragment is the name of the action, effect, or constraint, as + * specified by the #ClutterActorMeta:name property of #ClutterActorMeta + * - the `property-name` fragment is the name of the action, effect, or constraint + * property to be animated. + * + * The example below animates a #ClutterBindConstraint applied to an actor + * using an explicit transition. The `rect` actor has a binding constraint + * on the `origin` actor, and in its initial state is overlapping the actor + * to which is bound to. + * + * |[ + * constraint = clutter_bind_constraint_new (origin, CLUTTER_BIND_X, 0.0); + * clutter_actor_meta_set_name (CLUTTER_ACTOR_META (constraint), "bind-x"); + * clutter_actor_add_constraint (rect, constraint); + * + * constraint = clutter_bind_constraint_new (origin, CLUTTER_BIND_Y, 0.0); + * clutter_actor_meta_set_name (CLUTTER_ACTOR_META (constraint), "bind-y"); + * clutter_actor_add_constraint (rect, constraint); + * + * clutter_actor_set_reactive (origin, TRUE); + * + * g_signal_connect (origin, "button-press-event", + * G_CALLBACK (on_button_press), + * rect); + * ]| + * + * On button press, the rectangle "slides" from behind the actor to + * which is bound to, using the #ClutterBindConstraint:offset property to + * achieve the effect: + * + * |[ + * gboolean + * on_button_press (ClutterActor *origin, + * ClutterEvent *event, + * ClutterActor *rect) + * { + * ClutterTransition *transition; + * + * // the offset that we want to apply; this will make the actor + * // slide in from behind the origin and rest at the right of + * // the origin, plus a padding value + * float new_offset = clutter_actor_get_width (origin) + h_padding; + * + * // the property we wish to animate; the "@constraints" section + * // tells Clutter to check inside the constraints associated + * // with the actor; the "bind-x" section is the name of the + * // constraint; and the "offset" is the name of the property + * // on the constraint + * const char *prop = "@constraints.bind-x.offset"; + * + * // create a new transition for the given property + * transition = clutter_property_transition_new (prop); + * + * // set the easing mode and duration + * clutter_timeline_set_progress_mode (CLUTTER_TIMELINE (transition), + * CLUTTER_EASE_OUT_CUBIC); + * clutter_timeline_set_duration (CLUTTER_TIMELINE (transition), 500); + * + * // create the interval with the initial and final values + * clutter_transition_set_from (transition, G_TYPE_FLOAT, 0.f); + * clutter_transition_set_to (transition, G_TYPE_FLOAT, new_offset); + * + * // add the transition to the actor; this causes the animation + * // to start. the name "offsetAnimation" can be used to retrieve + * // the transition later + * clutter_actor_add_transition (rect, "offsetAnimation", transition); + * + * // we handled the event + * return CLUTTER_EVENT_STOP; + * } + * ]| + */ + +/** + * CLUTTER_ACTOR_IS_MAPPED: + * @a: a #ClutterActor + * + * Evaluates to %TRUE if the %CLUTTER_ACTOR_MAPPED flag is set. + * + * The mapped state is set when the actor is visible and all its parents up + * to a top-level (e.g. a #ClutterStage) are visible, realized, and mapped. + * + * This check can be used to see if an actor is going to be painted, as only + * actors with the %CLUTTER_ACTOR_MAPPED flag set are going to be painted. + * + * The %CLUTTER_ACTOR_MAPPED flag is managed by Clutter itself, and it should + * not be checked directly; instead, the recommended usage is to connect a + * handler on the #GObject::notify signal for the #ClutterActor:mapped + * property of #ClutterActor, and check the presence of + * the %CLUTTER_ACTOR_MAPPED flag on state changes. + * + * It is also important to note that Clutter may delay the changes of + * the %CLUTTER_ACTOR_MAPPED flag on top-levels due to backend-specific + * limitations, or during the reparenting of an actor, to optimize + * unnecessary (and potentially expensive) state changes. + * + * Since: 0.2 + * + * Deprecated: 1.24: Use clutter_actor_is_mapped() or the #ClutterActor:mapped + * property instead of this macro. + */ + +/** + * CLUTTER_ACTOR_IS_REALIZED: + * @a: a #ClutterActor + * + * Evaluates to %TRUE if the %CLUTTER_ACTOR_REALIZED flag is set. + * + * The realized state has an actor-dependant interpretation.

The offscreen image is used to flatten the + * actor into a single image while painting for two main reasons. + * Firstly, when the actor is painted a second time without any of its + * contents changing it can simply repaint the cached image without + * descending further down the actor hierarchy. Secondly, it will make + * the opacity look correct even if there are overlapping primitives + * in the actor. + * + * Caching the actor could in some cases be a performance win and in + * some cases be a performance lose so it is important to determine + * which value is right for an actor before modifying this value. For + * example, there is never any reason to flatten an actor that is just + * a single texture (such as a #ClutterTexture) because it is + * effectively already cached in an image so the offscreen would be + * redundant. Also if the actor contains primitives that are far apart + * with a large transparent area in the middle (such as a large + * CluterGroup with a small actor in the top left and a small actor in + * the bottom right) then the cached image will contain the entire + * image of the large area and the paint will waste time blending all + * of the transparent pixels in the middle. + * + * The default method of implementing opacity on a container simply + * forwards on the opacity to all of the children. If the children are + * overlapping then it will appear as if they are two separate glassy + * objects and there will be a break in the color where they + * overlap. By redirecting to an offscreen buffer it will be as if the + * two opaque objects are combined into one and then made transparent + * which is usually what is expected. + * + * The image below demonstrates the difference between redirecting and + * not. The image shows two Clutter groups, each containing a red and + * a green rectangle which overlap. The opacity on the group is set to + * 128 (which is 50%). When the offscreen redirect is not used, the + * red rectangle can be seen through the blue rectangle as if the two + * rectangles were separately transparent. When the redirect is used + * the group as a whole is transparent instead so the red rectangle is + * not visible where they overlap. + * + *
+ * Sample of using an offscreen redirect for transparency + * + *
+ * + * The default value for this property is 0, so we effectively will + * never redirect an actor offscreen by default.

The implementation of the function should look + * something like this: + * + * |[ + * void effect_paint (ClutterEffect *effect, ClutterEffectPaintFlags flags) + * { + * // Set up initialisation of the paint such as binding a + * // CoglOffscreen or other operations + * + * // Chain to the next item in the paint sequence. This will either call + * // ‘paint’ on the next effect or just paint the actor if this is + * // the last effect. + * ClutterActor *actor = + * clutter_actor_meta_get_actor (CLUTTER_ACTOR_META (effect)); + * + * clutter_actor_continue_paint (actor); + * + * // perform any cleanup of state, such as popping the CoglOffscreen + * } + * ]| + * + * The effect can optionally avoid calling clutter_actor_continue_paint() to skip any + * further stages of the paint sequence. This is useful for example if the effect + * contains a cached image of the actor.

This state + * signals the start of a gesture recognizing process. From the "begin" state + * the gesture recognition process can successfully end, by going to the + * "end" state; it can continue in the "progress" state, in case of a + * continuous gesture; or it can be terminated, by moving to the "cancel" + * state. + * + * In case of continuous gestures, the #ClutterGestureAction will use + * the "progress" state, calling the #ClutterGestureActionClass.gesture_progress() + * virtual function;

A + * layout manager implements the layouting policy for a composite or a + * container actor: it controls the preferred size of the actor to which + * it has been paired, and it controls the allocation of its children. + * + * Any composite or container #ClutterActor subclass can delegate the + * layouting of its children to a #ClutterLayoutManager. Clutter provides + * a generic container using #ClutterLayoutManager called #ClutterBox. + * + * Clutter provides some simple #ClutterLayoutManager sub-classes, like + * #ClutterFlowLayout and #ClutterBinLayout. + * + * ## Implementing a ClutterLayoutManager + * The implementation of a layout manager does not differ from the + * implementation of the size requisition and allocation bits of + * #ClutterActor, so you should read the relative documentation + * forr subclassing #ClutterActor. + * + * The layout manager implementation can hold a back pointer to the + * #ClutterContainer by implementing the #ClutterLayoutManagerClass.set_container() + * virtual function. The layout manager should not hold a real reference (i.e. + * call g_object_ref()) on the container actor, to avoid reference cycles. + * + * If a layout manager has properties affecting the layout policies then it should + * emit the #ClutterLayoutManager::layout-changed signal on itself by using the + * clutter_layout_manager_layout_changed() function whenever one of these properties + * changes. + * + * ## Layout Properties + * + * If a layout manager has layout properties, that is properties that + * should exist only as the result of the presence of a specific (layout + * manager, container actor, child actor) combination, and it wishes to store + * those properties inside a #ClutterLayoutMeta, then it should override the + * #ClutterLayoutManagerClass.get_child_meta_type() virtual function to return + * the #GType of the #ClutterLayoutMeta sub-class used to store the layout + * properties; optionally, the #ClutterLayoutManager sub-class might also + * override the #ClutterLayoutManagerClass.create_child_meta() virtual function + * to control how the #ClutterLayoutMeta instance is created, otherwise the + * default implementation will be equivalent to: + * + * |[ + * ClutterLayoutManagerClass *klass; + * GType meta_type; + * + * klass = CLUTTER_LAYOUT_MANAGER_GET_CLASS (manager); + * meta_type = klass->get_child_meta_type (manager); + * + * return g_object_new (meta_type, + * "manager", manager, + * "container", container, + * "actor", actor, + * NULL); + * ]| + * + * Where `manager` is the #ClutterLayoutManager, `container` is the + * #ClutterContainer using the #ClutterLayoutManager, and `actor` is + * the #ClutterActor child of the #ClutterContainer. + * + * ## Using ClutterLayoutManager with ClutterScript + * + * #ClutterLayoutManager instances can be created in the same way + * as other objects in #ClutterScript; properties can be set using the + * common syntax. + * + * Layout properties can be set on children of a container with + * a #ClutterLayoutManager using the `layout::` modifier on the property + * name, for instance: + * + * |[ + * { + * "type" : "ClutterBox", + * "layout-manager" : { "type" : "ClutterTableLayout" }, + * "children" : [ + * { + * "type" : "ClutterTexture", + * "filename" : "image-00.png", + * + * "layout::row" : 0, + * "layout::column" : 0, + * "layout::x-align" : "left", + * "layout::y-align" : "center", + * "layout::x-expand" : true, + * "layout::y-expand" : true + * }, + * { + * "type" : "ClutterTexture", + * "filename" : "image-01.png", + * + * "layout::row" : 0, + * "layout::column" : 1, + * "layout::x-align" : "right", + * "layout::y-align" : "center", + * "layout::x-expand" : true, + * "layout::y-expand" : true + * } + * ] + * } + * ]| + * + * #ClutterLayoutManager is available since Clutter 1.2 + */ + +#ifdef HAVE_CONFIG_H +#include "clutter-build-config.h" +#endif + +#include +#include + +#define CLUTTER_DISABLE_DEPRECATION_WARNINGS +#include "deprecated/clutter-container.h" +#include "deprecated/clutter-alpha.h" + +#include "clutter-debug.h" +#include "clutter-layout-manager.h" +#include "clutter-layout-meta.h" +#include "clutter-marshal.h" +#include "clutter-private.h" +#include "clutter-timeline.h" + +#define LAYOUT_MANAGER_WARN_NOT_IMPLEMENTED(m,method) G_STMT_START { \ + GObject *_obj = G_OBJECT (m);

This can be used in a + * #ClutterBehaviourPath to animate an actor moving along the path. + * + * The path consists of a series of nodes. Each node is one of the + * following four types: + * + * - %CLUTTER_PATH_MOVE_TO, changes the position of the path to the + * given pair of coordinates. This is usually used as the first node + * of a path to mark the start position. If it is used in the middle + * of a path then the path will be disjoint and the actor will appear + * to jump to the new position when animated. + * - %CLUTTER_PATH_LINE_TO, creates a straight line from the previous + * point to the given point. + * - %CLUTTER_PATH_CURVE_TO, creates a bezier curve. The end of the + * last node is used as the first control point and the three + * subsequent coordinates given in the node as used as the other three. + * -%CLUTTER_PATH_CLOSE, creates a straight line from the last node to + * the last %CLUTTER_PATH_MOVE_TO node. This can be used to close a + * path so that it will appear as a loop when animated. + * + * The first three types have the corresponding relative versions + * %CLUTTER_PATH_REL_MOVE_TO, %CLUTTER_PATH_REL_LINE_TO and + * %CLUTTER_PATH_REL_CURVE_TO. These are exactly the same except the + * coordinates are given relative to the previous node instead of as + * direct screen positions. + * + * You can build a path using the node adding functions such as + * clutter_path_add_line_to().

It is also convenient + * to implement the #ClutterShaderEffectClass.get_static_shader_source() + * virtual function in case you are planning to create more than one + * instance of the effect. + * + * The #ClutterShaderEffectClass.get_static_shader_source() + * function should return a copy of the shader source to use. This + * function is only called once per subclass of #ClutterShaderEffect + * regardless of how many instances of the effect are created. The + * source for the shader is typically stored in a static const + * string which is returned from this function via + * g_strdup(). + * + * The #ClutterOffscreenEffectClass.paint_target() should set the + * shader's uniforms if any. This is done by calling + * clutter_shader_effect_set_uniform_value() or + * clutter_shader_effect_set_uniform(). The sub-class should then + * chain up to the #ClutterShaderEffect implementation. + * + * ## Setting uniforms on a ClutterShaderEffect + * + * The example below shows a typical implementation of the + * #ClutterShaderEffectClass.get_static_shader_source() and + * #ClutterOffscreenEffectClass.paint_target() virtual functions + * for a #ClutterShaderEffect subclass. + * + * |[ + * static gchar * + * my_effect_get_static_shader_source (ClutterShaderEffect *effect) + * { + * // shader_source is set elsewhere + * return g_strdup (shader_source); + * } + * + * static gboolean + * my_effect_paint_target (ClutterOffscreenEffect *effect) + * { + * MyEffect *self = MY_EFFECT (effect); + * ClutterShaderEffect *shader = CLUTTER_SHADER_EFFECT (effect); + * ClutterEffectClass *parent_class; + * gfloat component_r, component_g, component_b; + * + * // the "tex" uniform is declared in the shader as: + * // + * // uniform int tex; + * // + * // and it is passed a constant value of 0 + * clutter_shader_effect_set_uniform (shader, "tex", G_TYPE_INT, 1, 0); + * + * // the "component" uniform is declared in the shader as: + * // + * // uniform vec3 component; + * // + * // and it's defined to contain the normalized components + * // of a #ClutterColor + * component_r = self->color.red / 255.0f; + * component_g = self->color.green / 255.0f; + * component_b = self->color.blue / 255.0f; + * clutter_shader_effect_set_uniform (shader, "component", + * G_TYPE_FLOAT, 3, + * component_r, + * component_g, + * component_b); + * + * // chain up to the parent's implementation + * parent_class = CLUTTER_OFFSCREEN_EFFECT_CLASS (my_effect_parent_class); + * return parent_class->paint_target (effect); + * } + * ]| + */ + +#ifdef HAVE_CONFIG_H +#include "clutter-build-config.h" +#endif + +#include "cogl/cogl.h" + +#include "clutter-shader-effect.h" + +#include "clutter-debug.h" +#include "clutter-enum-types.h" +#include "clutter-feature.h" +#include "clutter-private.h" +#include "clutter-shader-types.h" + +typedef struct _ShaderUniform +{ + gchar *name; + GType type; + GValue value; + int location; +} ShaderUniform; + +struct _ClutterShaderEffectPrivate +{ + ClutterActor *actor; + + ClutterShaderType shader_type; + + CoglHandle program; + CoglHandle shader; + + GHashTable *uniforms; +}; + +typedef struct _ClutterShaderEffectClassPrivate +{ + /* These are the per-class pre-compiled shader and program which is + used when the class implements get_static_shader_source without + calling set_shader_source.

If you need to schedule a closure + * after an interval, see clutter_threads_add_timeout() instead. + * + * Users of #ClutterTimeline should connect to the #ClutterTimeline::new-frame + * signal, which is emitted each time a timeline is advanced during the maste + * clock iteration. The #ClutterTimeline::new-frame signal provides the time + * elapsed since the beginning of the timeline, in milliseconds. A normalized + * progress value can be obtained by calling clutter_timeline_get_progress(). + * By using clutter_timeline_get_delta() it is possible to obtain the wallclock + * time elapsed since the last emission of the #ClutterTimeline::new-frame + * signal. + * + * Initial state can be set up by using the #ClutterTimeline::started signal, + * while final state can be set up by using the #ClutterTimeline::stopped + * signal. The #ClutterTimeline guarantees the emission of at least a single + * #ClutterTimeline::new-frame signal, as well as the emission of the + * #ClutterTimeline::completed signal every time the #ClutterTimeline reaches + * its #ClutterTimeline:duration. + * + * It is possible to connect to specific points in the timeline progress by + * adding markers using clutter_timeline_add_marker_at_time() and connecting + * to the #ClutterTimeline::marker-reached signal. + * + * Timelines can be made to loop once they reach the end of their duration, by + * using clutter_timeline_set_repeat_count(); a looping timeline will still + * emit the #ClutterTimeline::completed signal once it reaches the end of its + * duration at each repeat. If you want to be notified of the end of the last + * repeat, use the #ClutterTimeline::stopped signal. + * + * Timelines have a #ClutterTimeline:direction: the default direction is + * %CLUTTER_TIMELINE_FORWARD, and goes from 0 to the duration; it is possible + * to change the direction to %CLUTTER_TIMELINE_BACKWARD, and have the timeline + * go from the duration to 0. The direction can be automatically reversed + * when reaching completion by using the #ClutterTimeline:auto-reverse property. + * + * Timelines are used in the Clutter animation framework by classes like + * #ClutterAnimation, #ClutterAnimator, and #ClutterState. + * + * ## Defining Timelines in ClutterScript + * + * A #ClutterTimeline can be described in #ClutterScript like any + * other object.

The factor can + * then be used to drive a #ClutterBehaviour, which will translate the + * alpha value into something meaningful for a #ClutterActor. + * + * You should provide a #ClutterTimeline and bind it to the #ClutterAlpha + * instance using clutter_alpha_set_timeline(). You should also set an + * "animation mode", either by using the #ClutterAnimationMode values that + * Clutter itself provides or by registering custom functions using + * clutter_alpha_register_func(). + * + * Instead of a #ClutterAnimationMode you may provide a function returning + * the alpha value depending on the progress of the timeline, using + * clutter_alpha_set_func() or clutter_alpha_set_closure(). The alpha + * function will be executed each time a new frame in the #ClutterTimeline + * is reached. + * + * Since the alpha function is controlled by the timeline instance, you can + * pause, stop or resume the #ClutterAlpha from calling the alpha function by + * using the appropriate functions of the #ClutterTimeline object. + * + * #ClutterAlpha is used to "drive" a #ClutterBehaviour instance, and it + * is internally used by the #ClutterAnimation API. + * + * #ClutterAlpha is available since Clutter 0.2. + * + * #ClutterAlpha is deprecated since Clutter 1.12. #ClutterTimeline and + * the #ClutterTimeline:progress-mode property replace this whole class. + * + * ## ClutterAlpha custom properties for #ClutterScript + * + * #ClutterAlpha defines a custom `function` property for + * #ClutterScript which allows to reference a custom alpha function + * available in the source code. Setting the `function` property + * is equivalent to calling clutter_alpha_set_func() with the + * specified function name.

For each #GObject property + * there can be multiple key frames, each one defined by the end + * value for the property to be computed starting from the current + * value to a specific point in time, using a given easing + * mode. + * + * The point in time is defined using a value representing + * the progress in the normalized interval of [ 0, 1 ]. This maps + * the value returned by clutter_timeline_get_duration(). + * + * ## ClutterAnimator description for ClutterScript + * + * #ClutterAnimator defines a custom "properties" key + * which allows describing the key frames for objects as + * an array of key frames. + * + * The `properties` array has the following syntax: + * + * |[ + * { + * "properties" : [ + * { + * "object" : object_id + * "name" : property_name + * "ease-in" : true_or_false + * "interpolation" : interpolation_value + * "keys" : [ + * [ progress, easing_mode, final_value ] + * ] + * ] + * } + * ]| + * + * The following JSON fragment defines a #ClutterAnimator + * with the duration of 1 second and operating on the x and y + * properties of a #ClutterActor named "rect-01", with two frames + * for each property.

A + * behaviour is a controller object for #ClutterActors; you can + * use a behaviour to control one or more properties of an actor (such + * as its opacity, or its position).

The alpha function + * computes a value which is then applied to the properties of the + * actors driven by a behaviour. + * + * Clutter provides some pre-defined behaviours, like #ClutterBehaviourPath, + * which controls the position of a set of actors making them "walk" along + * a set of nodes; #ClutterBehaviourOpacity, which controls the opacity + * of a set of actors; #ClutterBehaviourScale, which controls the width + * and height of a set of actors. + * + * To visualize the effects of different alpha functions on a + * #ClutterBehaviour implementation it is possible to take the + * #ClutterBehaviourPath as an example: + * + * ![](path-alpha-func.png) + * + * The actors position between the path's end points directly correlates + * to the #ClutterAlpha's current alpha value driving the behaviour. With + * the #ClutterAlpha's function set to a linear ramp the actor + * will follow the path at a constant velocity, but when changing to + * a sine wave the actor initially accelerates before quickly + * decelerating. + * + * In order to implement a new behaviour you should subclass #ClutterBehaviour + * and override the "alpha_notify" virtual function; inside the overridden + * function you should obtain the alpha value from the #ClutterAlpha + * instance bound to the behaviour and apply it to the desiderd property + * (or properties) of every actor controlled by the behaviour. + * + * #ClutterBehaviour is available since Clutter 0.2. + * + * #ClutterBehaviour and its sub-classes have been discouraged sing Clutter + * 1.0, and formally deprecated since Clutter 1.6.

This can lead to + * performance degradation if the contents of the texture change + * frequently. + * + * In order to use a #ClutterCairoTexture you should connect to the + * #ClutterCairoTexture::draw signal; the signal is emitted each time + * the #ClutterCairoTexture has been told to invalidate its contents, + * by using clutter_cairo_texture_invalidate_rectangle() or its + * sister function, clutter_cairo_texture_invalidate(). + * + * Each callback to the #ClutterCairoTexture::draw signal will receive + * a #cairo_t context which can be used for drawing; the Cairo context + * is owned by the #ClutterCairoTexture and should not be destroyed + * explicitly. + * + * #ClutterCairoTexture is available since Clutter 1.0. + * + * #ClutterCairoTexture is deprecated since Clutter 1.12.

+ * - a child can also set a span, and this way, take + * more than one cell both horizontally and vertically; + * - each child will be allocated to its natural + * size or, if set to expand, the available size; + * - if a child is set to fill on either (or both) + * axis, its allocation will match all the available size; the + * fill layout property only makes sense if the expand property is + * also set; + * - if a child is set to expand but not to fill then + * it is possible to control the alignment using the horizontal and + * vertical alignment layout properties. + * + * It is possible to control the spacing between children of a + * #ClutterTableLayout by using clutter_table_layout_set_row_spacing() + * and clutter_table_layout_set_column_spacing(). + * + * In order to set the layout properties when packing an actor inside a + * #ClutterTableLayout you should use the clutter_table_layout_pack() + * function. + * + * A #ClutterTableLayout can use animations to transition between different + * values of the layout management properties; the easing mode and duration + * used for the animations are controlled by the + * #ClutterTableLayout:easing-mode and #ClutterTableLayout:easing-duration + * properties and their accessor functions. + * + * #ClutterTableLayout is available since Clutter 1.4 + * + * Since Clutter 1.18 it's recommended to use #ClutterGridLayout instead + * of #ClutterTableLayout; the former supports right-to-left text direction, + * as well as using the alignment and expansion flags on #ClutterActor. + */ + +#ifdef HAVE_CONFIG_H +#include "clutter-build-config.h" +#endif + +#include + +#define CLUTTER_DISABLE_DEPRECATION_WARNINGS +#include "deprecated/clutter-container.h" +#include "deprecated/clutter-alpha.h" + +#include "clutter-table-layout.h" + +#include "clutter-debug.h" +#include "clutter-enum-types.h" +#include "clutter-layout-meta.h" +#include "clutter-private.h" +#include "clutter-types.h" + +#define CLUTTER_TYPE_TABLE_CHILD (clutter_table_child_get_type ()) +#define CLUTTER_TABLE_CHILD(obj) (G_TYPE_CHECK_INSTANCE_CAST ((obj), CLUTTER_TYPE_TABLE_CHILD, ClutterTableChild)) +#define CLUTTER_IS_TABLE_CHILD(obj) (G_TYPE_CHECK_INSTANCE_TYPE ((obj), CLUTTER_TYPE_TABLE_CHILD)) + +typedef struct _ClutterTableChild ClutterTableChild;

It requires that + * the %CLUTTER_FEATURE_OFFSCREEN feature is supported by the current backend + * and the target system. + * + * Some tips on usage: + * + * - The source actor must be visible + * - The source actor must have a parent in order for it to be + * allocated a size from the layouting mechanism. If the source + * actor does not have a parent when this function is called then + * the ClutterTexture will adopt it and allocate it at its + * preferred size. Using this you can clone an actor that is + * otherwise not displayed. Because of this feature if you do + * intend to display the source actor then you must make sure that + * the actor is parented before calling + * clutter_texture_new_from_actor() or that you unparent it before + * adding it to a container. + * - When getting the image for the clone texture, Clutter + * will attempt to render the source actor exactly as it would + * appear if it was rendered on screen. The source actor's parent + * transformations are taken into account. Therefore if your + * source actor is rotated along the X or Y axes so that it has + * some depth, the texture will appear differently depending on + * the on-screen location of the source actor. While painting the + * source actor, Clutter will set up a temporary asymmetric + * perspective matrix as the projection matrix so that the source + * actor will be projected as if a small section of the screen was + * being viewed.

+Outline of test categories: + +The conform/ tests should be non-interactive unit-tests that verify a single +feature is behaving as documented. Use the GLib and Clutter test API and macros +to write the test units. The conformance test suites are meant to be used with +continuous integration builds. + +The performance/ tests are performance tests, both focused tests testing single +metrics and larger tests. These tests are used to report one or more +performance markers for the build of Clutter. Each performance marker is picked +up from the standard output of running the tests from strings having the form +"\n@ marker-name: 42.23" where 'marker-name' and '42.23' are the key/value pairs +of a single metric. Each test can provide multiple key/value pairs. Note that +if framerate is the feedback metric the test should forcibly enable FPS +debugging itself. The file test-common.h contains utility function helping to +do fps reporting. + +The interactive/ tests are any tests whose status can not be determined without +a user looking at some visual output, or providing some manual input etc. This +covers most of the original Clutter tests. Ideally some of these tests will be +migrated into the conform/ directory. + +The accessibility/ tests are tests created to test the accessibility support of +clutter, testing some of the atk interfaces. + +Other notes: + +• All tests should ideally include a detailed description in the source +explaining exactly what the test is for, how the test was designed to work, +and possibly a rationale for the approach taken for testing. Tests for specific +bugs should reference the bug report URL or number. + +• When running tests under Valgrind, you should follow the instructions +available here: + + https://wiki.gnome.org/Valgrind + +and also use the suppression file available in the Git repository. diff --git a/clutter/tests/accessibility/Makefile.am b/clutter/tests/accessibility/Makefile.am new file mode 100644 index 0000000..f3531db --- /dev/null +++ b/clutter/tests/accessibility/Makefile.am @@ -0,0 +1,36 @@ +common_ldadd = \ + $(top_builddir)/clutter/libmutter-clutter-@CLUTTER_API_VERSION@.la + +common_sources = \ + cally-examples-util.c \ + cally-examples-util.h + +AM_CPPFLAGS = \ + -DPREFIXDIR=\"$(libdir)\" \ + -DCLUTTER_DISABLE_DEPRECATION_WARNINGS \ + -DGLIB_DISABLE_DEPRECATION_WARNINGS \ + -I$(top_srcdir)/../cogl \ + -I$(top_builddir)/../cogl \ + -I$(top_srcdir) \ + -I$(top_builddir) \ + -I$(top_srcdir)/clutter \ + -I$(top_builddir)/clutter \ + -I$(top_srcdir)/tests/accessibility + +AM_CFLAGS = $(CLUTTER_CFLAGS) $(MAINTAINER_CFLAGS) +LDADD = $(common_ldadd) $(CLUTTER_LIBS) + +check_PROGRAMS = \ + cally-atkcomponent-example \ + cally-atkeditabletext-example \ + cally-atkevents-example \ + cally-atktext-example \ + cally-clone-example + +cally_atkcomponent_example_SOURCES = $(common_sources) cally-atkcomponent-example.c +cally_atktext_example_SOURCES = $(common_sources) cally-atktext-example.c +cally_atkevents_example_SOURCES = $(common_sources) cally-atkevents-example.c +cally_atkeditabletext_example_SOURCES = $(common_sources) cally-atkeditabletext-example.c +cally_clone_example_SOURCES = $(common_sources) cally-clone-example.c + +DISTCLEANFILES = diff --git a/clutter/tests/accessibility/Makefile.in b/clutter/tests/accessibility/Makefile.in new file mode 100644 index 0000000..ec1fe9e --- /dev/null +++ b/clutter/tests/accessibility/Makefile.in @@ -0,0 +1,750 @@ +# Makefile.in generated by automake 1.15 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994-2014 Free Software Foundation, Inc. + +# This Makefile.in is free software;

It is backward-compatible with the current + OpenGL Utilities tesselator, and is intended to replace it. Here is + a summary of the major differences: + + - input contours can be intersecting, self-intersecting, or degenerate. + + - supports a choice of several winding rules for determining which parts + of the polygon are on the "interior". This makes it possible to do + CSG operations on polygons. + + - boundary extraction: instead of tesselating the polygon, returns a + set of closed contours which separate the interior from the exterior. + + - returns the output as a small number of triangle fans and strips, + rather than a list of independent triangles (when possible). + + - output is available as an explicit mesh (a quad-edge structure), + in addition to the normal callback interface. + + - the algorithm used is extremely robust. + + +The interface +------------- + + The tesselator state is maintained in a "tesselator object". + These are allocated and destroyed using + + GLUtesselator *gluNewTess( void ); + void gluDeleteTess( GLUtesselator *tess ); + + Several tesselator objects may be used simultaneously. + + Inputs + ------ + + The input contours are specified with the following routines: + + void gluTessBeginPolygon( GLUtesselator *tess ); + void gluTessBeginContour( GLUtesselator *tess ); + void gluTessVertex( GLUtesselator *tess, GLUcoord coords[3], void *data ); + void gluTessEndContour( GLUtesselator *tess ); + void gluTessEndPolygon( GLUtesselator *tess ); + + Within each BeginPolygon/EndPolygon pair, there can be zero or more + calls to BeginContour/EndContour. Within each contour, there are zero + or more calls to gluTessVertex(). The vertices specify a closed + contour (the last vertex of each contour is automatically linked to + the first). + + "coords" give the coordinates of the vertex in 3-space. For useful + results, all vertices should lie in some plane, since the vertices + are projected onto a plane before tesselation. "data" is a pointer + to a user-defined vertex structure, which typically contains other + information such as color, texture coordinates, normal, etc. It is + used to refer to the vertex during rendering. + + The library can be compiled in single- or double-precision; the type + GLUcoord represents either "float" or "double" accordingly. The GLU + version will be available in double-precision only. Compile with + GLU_TESS_API_FLOAT defined to get the single-precision version. + + When EndPolygon is called, the tesselation algorithm determines + which regions are interior to the given contours, according to one + of several "winding rules" described below. The interior regions + are then tesselated, and the output is provided as callbacks. + + + Rendering Callbacks + ------------------- + + Callbacks are specified by the client using + + void gluTessCallback( GLUtesselator *tess, GLenum which, void (*fn)()); + + If "fn" is NULL, any previously defined callback is discarded. + + The callbacks used to provide output are: /* which == */ + + void begin( GLenum type ); /* GLU_TESS_BEGIN */ + void edgeFlag( GLboolean flag ); /* GLU_TESS_EDGE_FLAG */ + void vertex( void *data ); /* GLU_TESS_VERTEX */ + void end( void ); /* GLU_TESS_END */ + + Any of the callbacks may be left undefined; if so, the corresponding + information will not be supplied during rendering. + + The "begin" callback indicates the start of a primitive; type is one + of GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, or GL_TRIANGLES (but see the + notes on "boundary extraction" below). + + It is followed by any number of "vertex" callbacks, which supply the + vertices in the same order as expected by the corresponding glBegin() + call. After the last vertex of a given primitive, there is a callback + to "end". + + If the "edgeFlag" callback is provided, no triangle fans or strips + will be used. When edgeFlag is called, if "flag" is GL_TRUE then each + vertex which follows begins an edge which lies on the polygon boundary + (ie. an edge which separates an interior region from an exterior one). + If "flag" is GL_FALSE, each vertex which follows begins an edge which lies + in the polygon interior. "edgeFlag" will be called before the first + call to "vertex". + + Other Callbacks + --------------- + + void mesh( GLUmesh *mesh ); /* GLU_TESS_MESH */ + + - Returns an explicit mesh, represented using the quad-edge structure + (Guibas/Stolfi '85). Other implementations of this interface might + use a different mesh structure, so this is available only only as an + SGI extension. When the mesh is no longer needed, it should be freed + using + + void gluDeleteMesh( GLUmesh *mesh ); + + There is a brief description of this data structure in the include + file "mesh.h". For the full details, see L. Guibas and J. Stolfi, + Primitives for the manipulation of general subdivisions and the + computation of Voronoi diagrams, ACM Transactions on Graphics, + 4(2):74-123, April 1985. For an introduction, see the course notes + for CS348a, "Mathematical Foundations of Computer Graphics", + available at the Stanford bookstore (and taught during the fall + quarter). + + void error( GLenum errno ); /* GLU_TESS_ERROR */ + + - errno is one of GLU_TESS_MISSING_BEGIN_POLYGON, + GLU_TESS_MISSING_END_POLYGON, + GLU_TESS_MISSING_BEGIN_CONTOUR, + GLU_TESS_MISSING_END_CONTOUR, + GLU_TESS_COORD_TOO_LARGE, + GLU_TESS_NEED_COMBINE_CALLBACK + + The first four are obvious. The interface recovers from these + errors by inserting the missing call(s). + + GLU_TESS_COORD_TOO_LARGE says that some vertex coordinate exceeded + the predefined constant GLU_TESS_MAX_COORD in absolute value, and + that the value has been clamped. (Coordinate values must be small + enough so that two can be multiplied together without overflow.) + + GLU_TESS_NEED_COMBINE_CALLBACK says that the algorithm detected an + intersection between two edges in the input data, and the "combine" + callback (below) was not provided. No output will be generated. + + + void combine( GLUcoord coords[3], void *data[4], /* GLU_TESS_COMBINE */ + GLUcoord weight[4], void **outData ); + + - When the algorithm detects an intersection, or wishes to merge + features, it needs to create a new vertex. The vertex is defined + as a linear combination of up to 4 existing vertices, referenced + by data[0..3]. The coefficients of the linear combination are + given by weight[0..3]; these weights always sum to 1.0. All vertex + pointers are valid even when some of the weights are zero. + "coords" gives the location of the new vertex. + + The user must allocate another vertex, interpolate parameters + using "data" and "weights", and return the new vertex pointer in + "outData". This handle is supplied during rendering callbacks. + For example, if the polygon lies in an arbitrary plane in 3-space, + and we associate a color with each vertex, the combine callback might + look like this: + + void myCombine( GLUcoord coords[3], VERTEX *d[4], + GLUcoord w[4], VERTEX **dataOut ) + { + VERTEX *new = new_vertex(); + + new->x = coords[0]; + new->y = coords[1]; + new->z = coords[2]; + new->r = w[0]*d[0]->r + w[1]*d[1]->r + w[2]*d[2]->r + w[3]*d[3]->r; + new->g = w[0]*d[0]->g + w[1]*d[1]->g + w[2]*d[2]->g + w[3]*d[3]->g; + new->b = w[0]*d[0]->b + w[1]*d[1]->b + w[2]*d[2]->b + w[3]*d[3]->b; + new->a = w[0]*d[0]->a + w[1]*d[1]->a + w[2]*d[2]->a + w[3]*d[3]->a; + *dataOut = new; + } + + If the algorithm detects an intersection, then the "combine" callback + must be defined, and must write a non-NULL pointer into "dataOut". + Otherwise the GLU_TESS_NEED_COMBINE_CALLBACK error occurs, and no + output is generated. This is the only error that can occur during + tesselation and rendering. + + + Control over Tesselation + ------------------------ + + void gluTessProperty( GLUtesselator *tess, GLenum which, GLUcoord value ); + + Properties defined: + + - GLU_TESS_WINDING_RULE. Possible values: + + GLU_TESS_WINDING_ODD + GLU_TESS_WINDING_NONZERO + GLU_TESS_WINDING_POSITIVE + GLU_TESS_WINDING_NEGATIVE + GLU_TESS_WINDING_ABS_GEQ_TWO + + The input contours parition the plane into regions. A winding + rule determines which of these regions are inside the polygon. + + For a single contour C, the winding number of a point x is simply + the signed number of revolutions we make around x as we travel + once around C (where CCW is positive). When there are several + contours, the individual winding numbers are summed. This + procedure associates a signed integer value with each point x in + the plane. Note that the winding number is the same for all + points in a single region. + + The winding rule classifies a region as "inside" if its winding + number belongs to the chosen category (odd, nonzero, positive, + negative, or absolute value of at least two). The current GLU + tesselator implements the "odd" rule. The "nonzero" rule is another + common way to define the interior. The other three rules are + useful for polygon CSG operations (see below). + + - GLU_TESS_BOUNDARY_ONLY. Values: TRUE (non-zero) or FALSE (zero). + + If TRUE, returns a set of closed contours which separate the + polygon interior and exterior (rather than a tesselation). + Exterior contours are oriented CCW with respect to the normal, + interior contours are oriented CW. The GLU_TESS_BEGIN callback + uses the type GL_LINE_LOOP for each contour. + + - GLU_TESS_TOLERANCE. Value: a real number between 0.0 and 1.0. + + This specifies a tolerance for merging features to reduce the size + of the output. For example, two vertices which are very close to + each other might be replaced by a single vertex. The tolerance + is multiplied by the largest coordinate magnitude of any input vertex; + this specifies the maximum distance that any feature can move as the + result of a single merge operation. If a single feature takes part + in several merge operations, the total distance moved could be larger. + + Feature merging is completely optional; the tolerance is only a hint. + The implementation is free to merge in some cases and not in others, + or to never merge features at all. The default tolerance is zero. + + The current implementation merges vertices only if they are exactly + coincident, regardless of the current tolerance. A vertex is + spliced into an edge only if the implementation is unable to + distinguish which side of the edge the vertex lies on. + Two edges are merged only when both endpoints are identical. + + + void gluTessNormal( GLUtesselator *tess, + GLUcoord x, GLUcoord y, GLUcoord z ) + + - Lets the user supply the polygon normal, if known. All input data + is projected into a plane perpendicular to the normal before + tesselation. All output triangles are oriented CCW with + respect to the normal (CW orientation can be obtained by + reversing the sign of the supplied normal). For example, if + you know that all polygons lie in the x-y plane, call + "gluTessNormal(tess, 0.0, 0.0, 1.0)" before rendering any polygons. + + - If the supplied normal is (0,0,0) (the default value), the + normal is determined as follows. The direction of the normal, + up to its sign, is found by fitting a plane to the vertices, + without regard to how the vertices are connected. It is + expected that the input data lies approximately in plane; + otherwise projection perpendicular to the computed normal may + substantially change the geometry. The sign of the normal is + chosen so that the sum of the signed areas of all input contours + is non-negative (where a CCW contour has positive area). + + - The supplied normal persists until it is changed by another + call to gluTessNormal. + + + Backward compatibility with the GLU tesselator + ---------------------------------------------- + + The preferred interface is the one described above. The following + routines are obsolete, and are provided only for backward compatibility: + + typedef GLUtesselator GLUtriangulatorObj; /* obsolete name */ + + void gluBeginPolygon( GLUtesselator *tess ); + void gluNextContour( GLUtesselator *tess, GLenum type ); + void gluEndPolygon( GLUtesselator *tess ); + + "type" is one of GLU_EXTERIOR, GLU_INTERIOR, GLU_CCW, GLU_CW, or + GLU_UNKNOWN. It is ignored by the current GLU tesselator. + + GLU_BEGIN, GLU_VERTEX, GLU_END, GLU_ERROR, and GLU_EDGE_FLAG are defined + as synonyms for GLU_TESS_BEGIN, GLU_TESS_VERTEX, GLU_TESS_END, + GLU_TESS_ERROR, and GLU_TESS_EDGE_FLAG. + + +Polygon CSG operations +---------------------- + + The features of the tesselator make it easy to find the union, difference, + or intersection of several polygons. + + First, assume that each polygon is defined so that the winding number + is 0 for each exterior region, and 1 for each interior region. Under + this model, CCW contours define the outer boundary of the polygon, and + CW contours define holes. Contours may be nested, but a nested + contour must be oriented oppositely from the contour that contains it. + + If the original polygons do not satisfy this description, they can be + converted to this form by first running the tesselator with the + GLU_TESS_BOUNDARY_ONLY property turned on. This returns a list of + contours satisfying the restriction above. By allocating two + tesselator objects, the callbacks from one tesselator can be fed + directly to the input of another. + + Given two or more polygons of the form above, CSG operations can be + implemented as follows: + + Union + Draw all the input contours as a single polygon. The winding number + of each resulting region is the number of original polygons + which cover it. The union can be extracted using the + GLU_TESS_WINDING_NONZERO or GLU_TESS_WINDING_POSITIVE winding rules. + Note that with the nonzero rule, we would get the same result if + all contour orientations were reversed. + + Intersection (two polygons at a time only) + Draw a single polygon using the contours from both input polygons. + Extract the result using GLU_TESS_WINDING_ABS_GEQ_TWO. (Since this + winding rule looks at the absolute value, reversing all contour + orientations does not change the result.) + + Difference + + Suppose we want to compute A \ (B union C union D). Draw a single + polygon consisting of the unmodified contours from A, followed by + the contours of B,C,D with the vertex order reversed (this changes + the winding number of the interior regions to -1). To extract the + result, use the GLU_TESS_WINDING_POSITIVE rule. + + If B,C,D are the result of a GLU_TESS_BOUNDARY_ONLY call, an + alternative to reversing the vertex order is to reverse the sign of + the supplied normal. For example in the x-y plane, call + gluTessNormal( tess, 0.0, 0.0, -1.0 ). + + +Performance +----------- + + The tesselator is not intended for immediate-mode rendering; when + possible the output should be cached in a user structure or display + list. General polygon tesselation is an inherently difficult problem, + especially given the goal of extreme robustness. + + The implementation makes an effort to output a small number of fans + and strips; this should improve the rendering performance when the + output is used in a display list. + + Single-contour input polygons are first tested to see whether they can + be rendered as a triangle fan with respect to the first vertex (to + avoid running the full decomposition algorithm on convex polygons). + Non-convex polygons may be rendered by this "fast path" as well, if + the algorithm gets lucky in its choice of a starting vertex. + + For best performance follow these guidelines: + + - supply the polygon normal, if available, using gluTessNormal(). + This represents about 10% of the computation time. For example, + if all polygons lie in the x-y plane, use gluTessNormal(tess,0,0,1). + + - render many polygons using the same tesselator object, rather than + allocating a new tesselator for each one. (In a multi-threaded, + multi-processor environment you may get better performance using + several tesselators.) + + +Comparison with the GLU tesselator +---------------------------------- + + On polygons which make it through the "fast path", the tesselator is + 3 to 5 times faster than the GLU tesselator. + + On polygons which don't make it through the fast path (but which don't + have self-intersections or degeneracies), it is about 2 times slower. + + On polygons with self-intersections or degeneraces, there is nothing + to compare against. + + The new tesselator generates many more fans and strips, reducing the + number of vertices that need to be sent to the hardware. + + Key to the statistics: + + vert number of input vertices on all contours + cntr number of input contours + tri number of triangles in all output primitives + strip number of triangle strips + fan number of triangle fans + ind number of independent triangles + ms number of milliseconds for tesselation + (on a 150MHz R4400 Indy) + + Convex polygon examples: + +New: 3 vert, 1 cntr, 1 tri, 0 strip, 0 fan, 1 ind, 0.0459 ms +Old: 3 vert, 1 cntr, 1 tri, 0 strip, 0 fan, 1 ind, 0.149 ms +New: 4 vert, 1 cntr, 2 tri, 0 strip, 1 fan, 0 ind, 0.0459 ms +Old: 4 vert, 1 cntr, 2 tri, 0 strip, 0 fan, 2 ind, 0.161 ms +New: 36 vert, 1 cntr, 34 tri, 0 strip, 1 fan, 0 ind, 0.153 ms +Old: 36 vert, 1 cntr, 34 tri, 0 strip, 0 fan, 34 ind, 0.621 ms + + Concave single-contour polygons: + +New: 5 vert, 1 cntr, 3 tri, 0 strip, 1 fan, 0 ind, 0.052 ms +Old: 5 vert, 1 cntr, 3 tri, 0 strip, 0 fan, 3 ind, 0.252 ms +New: 19 vert, 1 cntr, 17 tri, 2 strip, 2 fan, 1 ind, 0.911 ms +Old: 19 vert, 1 cntr, 17 tri, 0 strip, 0 fan, 17 ind, 0.529 ms +New: 151 vert, 1 cntr, 149 tri, 13 strip, 18 fan, 3 ind, 6.82 ms +Old: 151 vert, 1 cntr, 149 tri, 0 strip, 3 fan, 143 ind, 2.7 ms +New: 574 vert, 1 cntr, 572 tri, 59 strip, 54 fan, 11 ind, 26.6 ms +Old: 574 vert, 1 cntr, 572 tri, 0 strip, 31 fan, 499 ind, 12.4 ms + + Multiple contours, but no intersections: + +New: 7 vert, 2 cntr, 7 tri, 1 strip, 0 fan, 0 ind, 0.527 ms +Old: 7 vert, 2 cntr, 7 tri, 0 strip, 0 fan, 7 ind, 0.274 ms +New: 81 vert, 6 cntr, 89 tri, 9 strip, 7 fan, 6 ind, 3.88 ms +Old: 81 vert, 6 cntr, 89 tri, 0 strip, 13 fan, 61 ind, 2.2 ms +New: 391 vert, 19 cntr, 413 tri, 37 strip, 32 fan, 26 ind, 20.2 ms +Old: 391 vert, 19 cntr, 413 tri, 0 strip, 25 fan, 363 ind, 8.68 ms + + Self-intersecting and degenerate examples: + +Bowtie: 4 vert, 1 cntr, 2 tri, 0 strip, 0 fan, 2 ind, 0.483 ms +Star: 5 vert, 1 cntr, 5 tri, 0 strip, 0 fan, 5 ind, 0.91 ms +Random: 24 vert, 7 cntr, 46 tri, 2 strip, 12 fan, 7 ind, 5.32 ms +Font: 333 vert, 2 cntr, 331 tri, 32 strip, 16 fan, 3 ind, 14.1 ms +: 167 vert, 35 cntr, 254 tri, 8 strip, 56 fan, 52 ind, 46.3 ms +: 78 vert, 1 cntr, 2675 tri, 148 strip, 207 fan, 180 ind, 243 ms +: 12480 vert, 2 cntr, 12478 tri, 736 strip,1275 fan, 5 ind, 1010 ms diff --git a/cogl/cogl-path/tesselator/dict-list.h b/cogl/cogl-path/tesselator/dict-list.h new file mode 100644 index 0000000..11331a7 --- /dev/null +++ b/cogl/cogl-path/tesselator/dict-list.h @@ -0,0 +1,100 @@ +/* + * SGI FREE SOFTWARE LICENSE B (Version 2.0, Sept. 18, 2008) + * Copyright (C) 1991-2000 Silicon Graphics, Inc.

Mantyla, An Introduction + * to Sold Modeling, Computer Science Press, Rockville, Maryland, 1988). + * + * The fundamental data structure is the "half-edge". Two half-edges + * go together to make an edge, but they point in opposite directions. + * Each half-edge has a pointer to its mate (the "symmetric" half-edge Sym), + * its origin vertex (Org), the face on its left side (Lface), and the + * adjacent half-edges in the CCW direction around the origin vertex + * (Onext) and around the left face (Lnext). There is also a "next" + * pointer for the global edge list (see below). + * + * The notation used for mesh navigation: + * Sym = the mate of a half-edge (same edge, but opposite direction) + * Onext = edge CCW around origin vertex (keep same origin) + * Dnext = edge CCW around destination vertex (keep same dest) + * Lnext = edge CCW around left face (dest becomes new origin) + * Rnext = edge CCW around right face (origin becomes new dest) + * + * "prev" means to substitute CW for CCW in the definitions above. + * + * The mesh keeps global lists of all vertices, faces, and edges, + * stored as doubly-linked circular lists with a dummy header node. + * The mesh stores pointers to these dummy headers (vHead, fHead, eHead). + * + * The circular edge list is special; since half-edges always occur + * in pairs (e and e->Sym), each half-edge stores a pointer in only + * one direction. Starting at eHead and following the e->next pointers + * will visit each *edge* once (ie. e or e->Sym, but not both). + * e->Sym stores a pointer in the opposite direction, thus it is + * always true that e->Sym->next->Sym->next == e. + * + * Each vertex has a pointer to next and previous vertices in the + * circular list, and a pointer to a half-edge with this vertex as + * the origin (NULL if this is the dummy header).

There is also + * a field "data" for client data. + * + * Note that what we call a "face" is really a loop; faces may consist + * of more than one loop (ie. not simply connected), but there is no + * record of this in the data structure. The mesh may consist of + * several disconnected regions, so it may not be possible to visit + * the entire mesh by starting at a half-edge and traversing the edge + * structure. + * + * The mesh does NOT support isolated vertices; a vertex is deleted along + * with its last edge. Similarly when two faces are merged, one of the + * faces is deleted (see __gl_meshDelete below). For mesh operations, + * all face (loop) and vertex pointers must not be NULL.

There are several cases: + * if (eDel->Lface != eDel->Rface), we join two loops into one; the loop + * eDel->Lface is deleted. Otherwise, we are splitting one loop into two; + * the newly created loop will contain eDel->Dst. If the deletion of eDel + * would create isolated vertices, those are deleted as well. + * + * ********************** Other Edge Operations ************************** + * + * __gl_meshAddEdgeVertex( eOrg ) creates a new edge eNew such that + * eNew == eOrg->Lnext, and eNew->Dst is a newly created vertex. + * eOrg and eNew will have the same left face. + * + * __gl_meshSplitEdge( eOrg ) splits eOrg into two edges eOrg and eNew, + * such that eNew == eOrg->Lnext. The new vertex is eOrg->Dst == eNew->Org. + * eOrg and eNew will have the same left face. + * + * __gl_meshConnect( eOrg, eDst ) creates a new edge from eOrg->Dst + * to eDst->Org, and returns the corresponding half-edge eNew. + * If eOrg->Lface == eDst->Lface, this splits one loop into two, + * and the newly created loop is eNew->Lface. Otherwise, two disjoint + * loops are merged into one, and the loop eDst->Lface is destroyed. + * + * ************************ Other Operations ***************************** + * + * __gl_meshNewMesh() creates a new mesh with no edges, no vertices, + * and no loops (what we usually call a "face"). + * + * __gl_meshUnion( mesh1, mesh2 ) forms the union of all structures in + * both meshes, and returns the new mesh (the old meshes are destroyed). + * + * __gl_meshDeleteMesh( mesh ) will free all storage for any valid mesh. + * + * __gl_meshZapFace( fZap ) destroys a face and removes it from the + * global face list.

Its main purpose is to act as a sandbox + * for the memory management of state objects. Normally an application + * will only create a single context since there is no way to share + * resources between contexts. + * + * For those familiar with OpenGL or perhaps Cairo it should be + * understood that unlike these APIs a Cogl context isn't a rendering + * context as such. In other words Cogl doesn't aim to provide a state + * machine style model for configuring rendering parameters. Most + * rendering state in Cogl is directly associated with user managed + * objects called pipelines and geometry is drawn with a specific + * pipeline object to a framebuffer object and those 3 things fully + * define the state for drawing. This is an important part of Cogl's + * design since it helps you write orthogonal rendering components + * that can all access the same GPU without having to worry about + * what state other components have left you with. + * + * Cogl does not maintain internal references to the context for + * resources that depend on the context so applications.

The values could be passed to Cogl only when + * manipulation is necessary. + * + * + * + * Disadvantages: + * + * + * Aliasing: it's possible to represent some rotations with multiple + * different heading, pitch and roll rotations. + * + * + * They can suffer from a problem called Gimbal Lock. A good + * explanation of this can be seen on wikipedia here: + * http://en.wikipedia.org/wiki/Gimbal_lock but basically two + * of the axis of rotation may become aligned and so you loose a + * degree of freedom. For example a pitch of +-90° would mean that + * heading and bank rotate around the same axis. + * + * + * If you use euler angles to orient something in 3D space and try to + * transition between orientations by interpolating the component + * angles you probably wont get the transitions you expect as they may + * not follow the shortest path between the two orientations. + * + * + * There's no standard to what order the component axis rotations are + * applied. The most common convention seems to be what we do in Cogl + * with heading (y-axis), pitch (x-axis) and then roll (z-axis), but + * other software might apply x-axis, y-axis then z-axis or any other + * order so you need to consider this if you are accepting euler + * rotations from some other software.

Other + * configuration parameters are associated with framebuffers too such + * as whether the framebuffer supports multi-sampling (an anti-aliasing + * technique) or dithering. + * + * There are two kinds of framebuffer in Cogl, #CoglOnscreen + * framebuffers and #CoglOffscreen framebuffers. As the names imply + * offscreen framebuffers are for rendering something offscreen + * (perhaps to a texture which is bound as one of the color buffers). + * The exact semantics of onscreen framebuffers depends on the window + * system backend that you are using, but typically you can expect + * rendering to a #CoglOnscreen framebuffer will be immediately + * visible to the user. + * + * If you want to create a new framebuffer then you should start by + * looking at the #CoglOnscreen and #CoglOffscreen constructor + * functions, such as cogl_offscreen_new_with_texture() or + * cogl_onscreen_new().

Reducing the size of + * your models can make it cheaper to map them into the GPU by + * reducing the demand on memory bandwidth and may help to make better + * use of your GPUs internal vertex caching. + * + * For example, to describe a quadrilateral as 2 triangles for the GPU + * you could either provide data with 6 vertices or instead with + * indices you can provide vertex data for just 4 vertices and an + * index buffer that specfies the 6 vertices by indexing the shared + * vertices multiple times. + * + * |[ + * CoglVertex2f quad_vertices[] = { + * {x0, y0}, //0 = top left + * {x1, y1}, //1 = bottom left + * {x2, y2}, //2 = bottom right + * {x3, y3}, //3 = top right + * }; + * //tell the gpu how to interpret the quad as 2 triangles... + * unsigned char indices[] = {0, 1, 2, 0, 2, 3}; + * ]| + * + * Even in the above illustration we see a saving of 10bytes for one + * quad compared to having data for 6 vertices and no indices but if + * you need to draw 100s or 1000s of quads then its really quite + * significant. + * + * Something else to consider is that often indices can be defined + * once and remain static while the vertex data may change for + * animations perhaps. That means you may be able to ignore the + * negligable cost of mapping your indices into the GPU if they don't + * ever change. + * + * The above illustration is actually a good example of static indices + * because it's really common that developers have quad mesh data that + * they need to display and we know exactly what that indices array + * needs to look like depending on the number of quads that need to be + * drawn.

The reason this works is + * because cogl_rectangle() internally understands the #CoglMetaTexture + * interface and is able to manually resolve the low-level textures + * using this interface and by making multiple draw calls it can + * emulate the texture repeat modes. + * + * Cogl doesn't aim to pretend that meta-textures are just like real + * textures because it would get extremely complex to try and emulate + * low-level GPU semantics transparently for these textures. The low + * level drawing APIs of Cogl, such as cogl_primitive_draw() don't + * actually know anything about the #CoglMetaTexture interface and its + * the developer's responsibility to resolve all textures referenced + * by a #CoglPipeline to low-level textures before drawing. + * + * If you want to develop custom primitive APIs like + * cogl_framebuffer_draw_rectangle() and you want to support drawing + * with #CoglAtlasTextures or #CoglSubTextures for + * example, then you will need to use this #CoglMetaTexture interface + * to be able to resolve high-level textures into low-level textures + * before drawing with Cogl's low-level drawing APIs such as + * cogl_primitive_draw(). + * + * Most developers won't need to use this interface directly + * but still it is worth understanding the distinction between + * low-level and meta textures because you may find other references + * in the documentation that detail limitations of using + * meta-textures. + */ + +#if defined(__COGL_H_INSIDE__) && !defined(COGL_ENABLE_MUTTER_API) && \ + !defined(COGL_GIR_SCANNING) +/* For the public C api we typedef interface types as void to avoid needing + * lots of casting in code and instead we will rely on runtime type checking + * for these objects. */ +typedef void CoglMetaTexture; +#else +typedef struct _CoglMetaTexture CoglMetaTexture; +#define COGL_META_TEXTURE(X) ((CoglMetaTexture *)X) +#endif + +/** + * CoglMetaTextureCallback: + * @sub_texture: A low-level #CoglTexture making up part of a + * #CoglMetaTexture. + * @sub_texture_coords: A float 4-tuple ordered like + * (tx1,ty1,tx2,ty2) defining what region of the + * current @sub_texture maps to a sub-region of a + * #CoglMetaTexture.

Because a node depends on its ancestors it normally + * owns a reference to its parent to stop it from being freed. Also if + * you try to modify a pipeline with children we internally use a + * copy-on-write mechanism to ensure that you don't indirectly change + * the properties those children. + * + * Weak pipelines avoid the use of copy-on-write to preserve the + * integrity of weak dependants and instead weak dependants are + * simply destroyed allowing the parent to be modified directly.

To handle this you + * implement a validation stage that given an arbitrary pipeline as + * input will create a derived pipeline that is suitable for drawing + * your primitive. + * + * Because you don't want to have to repeat this validation every time + * the same incompatible pipeline is given as input you want to cache + * the result as a private property of the original pipeline. If the + * derived pipeline were created using cogl_pipeline_copy that would + * create a circular dependency so the original pipeline can never be + * freed. + * + * If you instead create a weak copy you won't stop the original pipeline + * from being freed if it's no longer needed, and you will instead simply + * be notified that your weak pipeline has been destroyed. + * + * This is the recommended coding pattern for validating an input + * pipeline and caching a derived result: + * |[ + * static CoglUserDataKey _cogl_my_cache_key; + * + * typedef struct { + * CoglPipeline *validated_source; + * } MyValidatedMaterialCache; + * + * static void + * destroy_cache_cb (CoglObject *object, void *user_data) + * { + * g_slice_free (MyValidatedMaterialCache, user_data); + * } + * + * static void + * invalidate_cache_cb (CoglPipeline *destroyed, void *user_data) + * { + * MyValidatedMaterialCache *cache = user_data; + * cogl_object_unref (cache->validated_source); + * cache->validated_source = NULL; + * } + * + * static CoglPipeline * + * get_validated_pipeline (CoglPipeline *source) + * { + * MyValidatedMaterialCache *cache = + * cogl_object_get_user_data (COGL_OBJECT (source), + * &_cogl_my_cache_key); + * if (G_UNLIKELY (cache == NULL)) + * { + * cache = g_slice_new (MyValidatedMaterialCache); + * cogl_object_set_user_data (COGL_OBJECT (source), + * &_cogl_my_cache_key, + * cache, destroy_cache_cb); + * cache->validated_source = source; + * } + * + * if (G_UNLIKELY (cache->validated_source == NULL)) + * { + * cache->validated_source = source; + * + * / * Start validating source... * / + * + * / * If you find you need to change something... * / + * if (cache->validated_source == source) + * cache->validated_source = + * cogl_pipeline_weak_copy (source, + * invalidate_cache_cb, + * cache); + * + * / * Modify cache->validated_source * / + * } + * + * return cache->validated_source; + * } + * ]| + */ +CoglPipeline * +_cogl_pipeline_weak_copy (CoglPipeline *pipeline, + CoglPipelineDestroyCallback callback, + void *user_data); + +void +_cogl_pipeline_set_progend (CoglPipeline *pipeline, int progend); + +CoglPipeline * +_cogl_pipeline_get_parent (CoglPipeline *pipeline); + +void +_cogl_pipeline_get_colorubv (CoglPipeline *pipeline, + uint8_t *color); + +/* XXX: At some point it could be good for this to accept a mask of + * the state groups we are interested in comparing since we can + * probably use that information in a number situations to reduce + * the work we do. */ +unsigned long +_cogl_pipeline_compare_differences (CoglPipeline *pipeline0, + CoglPipeline *pipeline1); + +CoglBool +_cogl_pipeline_equal (CoglPipeline *pipeline0, + CoglPipeline *pipeline1, + unsigned int differences, + unsigned long layer_differences, + CoglPipelineEvalFlags flags); + +unsigned int +_cogl_pipeline_hash (CoglPipeline *pipeline, + unsigned int differences, + unsigned long layer_differences, + CoglPipelineEvalFlags flags); + +/* Makes a copy of the given pipeline that is a child of the root + * pipeline rather than a child of the source pipeline.

GLSL is a programming language supported + * by OpenGL on programmable hardware to provide a more flexible + * description of what should be rendered. A description of GLSL + * itself is outside the scope of this documentation but any good + * OpenGL book should help to describe it. + * + * Unlike in OpenGL, when using GLSL with Cogl it is possible to write + * short snippets to replace small sections of the pipeline instead of + * having to replace the whole of either the vertex or fragment + * pipelines. Of course it is also possible to replace the whole of + * the pipeline if needed. + * + * Each snippet is a standalone chunk of code which would attach to + * the pipeline at a particular point. The code is split into four + * separate strings (all of which are optional): + * + * + * + * declarations + * + * The code in this string will be inserted outside of any function in + * the global scope of the shader. This can be used to declare + * uniforms, attributes, varyings and functions to be used by the + * snippet. + * + * + * + * pre + * + * The code in this string will be inserted before the hook point. + * + * + * + * post + * + * The code in this string will be inserted after the hook point. This + * can be used to modify the results of the builtin generated code for + * that hook point. + * + * + * + * replace + * + * If present the code in this string will replace the generated code + * for the hook point. + * + * + * + * + * All of the strings apart from the declarations string of a pipeline + * are generated in a single function so they can share variables + * declared from one string in another. The scope of the code is + * limited to each snippet so local variables declared in the snippet + * will not collide with variables declared in another + * snippet. However, code in the 'declarations' string is global to + * the shader so it is the application's responsibility to ensure that + * variables declared here will not collide with those from other + * snippets. + * + * The snippets can be added to a pipeline with + * cogl_pipeline_add_snippet() or + * cogl_pipeline_add_layer_snippet(). Which function to use depends on + * which hook the snippet is targetting. The snippets are all + * generated in the order they are added to the pipeline. That is, the + * post strings are executed in the order they are added to the + * pipeline and the pre strings are executed in reverse order. If any + * replace strings are given for a snippet then any other snippets + * with the same hook added before that snippet will be ignored. The + * different hooks are documented under #CoglSnippetHook. + * + * For portability with GLES2, it is recommended not to use the GLSL + * builtin names such as gl_FragColor. Instead there are replacement + * names under the cogl_* namespace which can be used instead. These + * are: + * + * + * + * uniform mat4 + * cogl_modelview_matrix + * + * The current modelview matrix. This is equivalent to + * #gl_ModelViewMatrix. + * + * + * + * uniform mat4 + * cogl_projection_matrix + * + * The current projection matrix. This is equivalent to + * #gl_ProjectionMatrix. + * + * + * + * uniform mat4 + * cogl_modelview_projection_matrix + * + * The combined modelview and projection matrix. A vertex shader + * would typically use this to transform the incoming vertex + * position. The separate modelview and projection matrices are + * usually only needed for lighting calculations. This is + * equivalent to #gl_ModelViewProjectionMatrix. + * + * + * + * uniform mat4 + * cogl_texture_matrix[] + * + * An array of matrices for transforming the texture + * coordinates. This is equivalent to #gl_TextureMatrix. + * + * + * + * + * In a vertex shader, the following are also available: + * + * + * + * attribute vec4 + * cogl_position_in + * + * The incoming vertex position. This is equivalent to #gl_Vertex. + * + * + * + * attribute vec4 + * cogl_color_in + * + * The incoming vertex color. This is equivalent to #gl_Color. + * + * + * + * attribute vec4 + * cogl_tex_coord_in + * + * The texture coordinate for layer 0. This is an alternative name + * for #cogl_tex_coord0_in. + * + * + * + * attribute vec4 + * cogl_tex_coord0_in + * + * The texture coordinate for the layer 0. This is equivalent to + * #gl_MultiTexCoord0. There will also be #cogl_tex_coord1_in and + * so on if more layers are added to the pipeline. + * + * + * + * attribute vec3 + * cogl_normal_in + * + * The normal of the vertex. This is equivalent to #gl_Normal. + * + * + * + * vec4 + * cogl_position_out + * + * The calculated position of the vertex. This must be written to + * in all vertex shaders. This is equivalent to #gl_Position. + * + * + * + * float + * cogl_point_size_in + * + * The incoming point size from the cogl_point_size_in attribute. + * This is only available if + * cogl_pipeline_set_per_vertex_point_size() is set on the + * pipeline. + * + * + * + * float + * cogl_point_size_out + * + * The calculated size of a point. This is equivalent to #gl_PointSize. + * + * + * + * varying vec4 + * cogl_color_out + * + * The calculated color of a vertex. This is equivalent to #gl_FrontColor. + * + * + * + * varying vec4 + * cogl_tex_coord0_out + * + * The calculated texture coordinate for layer 0 of the pipeline. + * This is equivalent to #gl_TexCoord[0]. There will also be + * #cogl_tex_coord1_out and so on if more layers are added to the + * pipeline. In the fragment shader, this varying is called + * #cogl_tex_coord0_in. + * + * + * + * + * In a fragment shader, the following are also available: + * + * + * + * varying vec4 cogl_color_in + * + * The calculated color of a vertex. This is equivalent to #gl_FrontColor. + * + * + * + * varying vec4 + * cogl_tex_coord0_in + * + * The texture coordinate for layer 0. This is equivalent to + * #gl_TexCoord[0]. There will also be #cogl_tex_coord1_in and so + * on if more layers are added to the pipeline. + * + * + * + * vec4 cogl_color_out + * + * The final calculated color of the fragment. All fragment shaders + * must write to this variable. This is equivalent to + * #gl_FrontColor. + * + * + * + * float cogl_depth_out + * + * An optional output variable specifying the depth value to use + * for this fragment. This is equivalent to #gl_FragDepth. + * + * + * + * bool cogl_front_facing + * + * A readonly variable that will be true if the current primitive + * is front facing. This can be used to implement two-sided + * coloring algorithms. This is equivalent to #gl_FrontFacing. + * + * + * + * vec2 cogl_point_coord + * + * When rendering points, this will contain a vec2 which represents + * the position within the point of the current fragment. + * vec2(0.0,0.0) will be the topleft of the point and vec2(1.0,1.0) + * will be the bottom right. Note that there is currently a bug in + * Cogl where when rendering to an offscreen buffer these + * coordinates will be upside-down. The value is undefined when not + * rendering points.

This can be used to modify + * cogl_point_size_out in addition to the default processing. + * + * + * + * + * %COGL_SNIPPET_HOOK_FRAGMENT + * + * + * Adds a shader snippet that will hook on to the fragment processing + * stage of the pipeline. This gives a chance for the application to + * modify the fragment color generated by the shader. Typically the + * snippet will modify cogl_color_out. + * + * + * The ‘declarations’ string in @snippet will be inserted in the + * global scope of the shader. Use this to declare any uniforms, + * attributes or functions that the snippet requires. + * + * + * The ‘pre’ string in @snippet will be inserted at the top of the + * main() function before any fragment processing is done. + * + * + * The ‘replace’ string in @snippet will be used instead of the + * generated fragment processing if it is present. This can be used if + * the application wants to provide a complete fragment shader and + * doesn't need the generated output from Cogl. + * + * + * The ‘post’ string in @snippet will be inserted after all of the + * standard fragment processing is done. At this point the generated + * value for the rest of the pipeline state will already be in + * cogl_color_out so the application can modify the result by altering + * this variable. + * + * + * + * + * %COGL_SNIPPET_HOOK_TEXTURE_COORD_TRANSFORM + * + * + * Adds a shader snippet that will hook on to the texture coordinate + * transformation of a particular layer. This can be used to replace + * the processing for a layer or to modify the results. + * + * + * Within the snippet code for this hook there are two extra + * variables. The first is a mat4 called cogl_matrix which represents + * the user matrix for this layer. The second is called cogl_tex_coord + * and represents the incoming and outgoing texture coordinate. On + * entry to the hook, cogl_tex_coord contains the value of the + * corresponding texture coordinate attribute for this layer. The hook + * is expected to modify this variable. The output will be passed as a + * varying to the fragment processing stage. The default code will + * just multiply cogl_matrix by cogl_tex_coord and store the result in + * cogl_tex_coord. + * + * + * The ‘declarations’ string in @snippet will be inserted in the + * global scope of the shader. Use this to declare any uniforms, + * attributes or functions that the snippet requires. + * + * + * The ‘pre’ string in @snippet will be inserted just before the + * fragment processing for this layer. At this point cogl_tex_coord + * still contains the value of the texture coordinate attribute. + * + * + * If a ‘replace’ string is given then this will be used instead of + * the default fragment processing for this layer. The snippet can + * modify cogl_tex_coord or leave it as is to apply no transformation. + * + * + * The ‘post’ string in @snippet will be inserted just after the + * transformation. At this point cogl_tex_coord will contain the + * results of the transformation but it can be further modified by the + * snippet. + * + * + * + * + * %COGL_SNIPPET_HOOK_LAYER_FRAGMENT + * + * + * Adds a shader snippet that will hook on to the fragment processing + * of a particular layer. This can be used to replace the processing + * for a layer or to modify the results. + * + * + * Within the snippet code for this hook there is an extra vec4 + * variable called ‘cogl_layer’. This contains the resulting color + * that will be used for the layer. This can be modified in the ‘post’ + * section or it the default processing can be replaced entirely using + * the ‘replace’ section. + * + * + * The ‘declarations’ string in @snippet will be inserted in the + * global scope of the shader. Use this to declare any uniforms, + * attributes or functions that the snippet requires. + * + * + * The ‘pre’ string in @snippet will be inserted just before the + * fragment processing for this layer. + * + * + * If a ‘replace’ string is given then this will be used instead of + * the default fragment processing for this layer. The snippet must write to + * the ‘cogl_layer’ variable in that case. + * + * + * The ‘post’ string in @snippet will be inserted just after the + * fragment processing for the layer. The results can be modified by changing + * the value of the ‘cogl_layer’ variable. + * + * + * + * + * %COGL_SNIPPET_HOOK_TEXTURE_LOOKUP + * + * + * Adds a shader snippet that will hook on to the texture lookup part + * of a given layer. This gives a chance for the application to modify + * the coordinates that will be used for the texture lookup or to + * alter the returned texel. + * + * + * Within the snippet code for this hook there are three extra + * variables available. ‘cogl_sampler’ is a sampler object + * representing the sampler for the layer where the snippet is + * attached. ‘cogl_tex_coord’ is a vec4 which contains the texture + * coordinates that will be used for the texture lookup. This can be + * modified. ‘cogl_texel’ will contain the result of the texture + * lookup. This can also be modified. + * + * + * The ‘declarations’ string in @snippet will be inserted in the + * global scope of the shader. Use this to declare any uniforms, + * attributes or functions that the snippet requires. + * + * + * The ‘pre’ string in @snippet will be inserted at the top of the + * main() function before any fragment processing is done. This is a + * good place to modify the cogl_tex_coord variable. + * + * + * If a ‘replace’ string is given then this will be used instead of a + * the default texture lookup. The snippet would typically use its own + * sampler in this case. + * + * + * The ‘post’ string in @snippet will be inserted after texture lookup + * has been preformed. Here the snippet can modify the cogl_texel + * variable to alter the returned texel. + * + * + * + * + * + * Since: 1.10 + * Stability: Unstable + */ +typedef enum { + /* Per pipeline vertex hooks */ + COGL_SNIPPET_HOOK_VERTEX = 0, + COGL_SNIPPET_HOOK_VERTEX_TRANSFORM, + COGL_SNIPPET_HOOK_VERTEX_GLOBALS, + COGL_SNIPPET_HOOK_POINT_SIZE, + + /* Per pipeline fragment hooks */ + COGL_SNIPPET_HOOK_FRAGMENT = 2048, + COGL_SNIPPET_HOOK_FRAGMENT_GLOBALS, + + /* Per layer vertex hooks */ + COGL_SNIPPET_HOOK_TEXTURE_COORD_TRANSFORM = 4096, + + /* Per layer fragment hooks */ + COGL_SNIPPET_HOOK_LAYER_FRAGMENT = 6144, + COGL_SNIPPET_HOOK_TEXTURE_LOOKUP +} CoglSnippetHook; + +/** + * cogl_snippet_new: + * @hook: The point in the pipeline that this snippet will wrap around + * or replace. + * @declarations: The source code for the declarations for this + * snippet or %NULL.

For example if you have a + * virtual texture that's 259 texels wide, the next pot size = 512 and + * the amount of waste would be 253 texels.

+------------------- +These tests should be non-interactive unit-tests that verify a single +feature is behaving as documented. See conform/ADDING_NEW_TESTS for more +details. + +Although it may seem a bit awkward; all the tests are built into a +single binary because it makes building the tests *much* faster by avoiding +lots of linking. + +Each test has a wrapper script generated though so running the individual tests +should be convenient enough. Running the wrapper script will also print out for +convenience how you could run the test under gdb or valgrind like this for +example: + + NOTE: For debugging purposes, you can run this single test as follows: + $ libtool --mode=execute \ + gdb --eval-command="b test_cogl_depth_test" \ + --args ./test-conformance -p /conform/cogl/test_cogl_depth_test + or: + $ env G_SLICE=always-malloc \ + libtool --mode=execute \ + valgrind ./test-conformance -p /conform/cogl/test_cogl_depth_test + +By default the conformance tests are run offscreen. This makes the tests run +much faster and they also don't interfere with other work you may want to do by +constantly stealing focus. CoglOnscreen framebuffers obviously don't get tested +this way so it's important that the tests also get run onscreen every once in a +while, especially if changes are being made to CoglFramebuffer related code. +Onscreen testing can be enabled by setting COGL_TEST_ONSCREEN=1 in your +environment. + +The micro-bench/ tests: +----------------------- +These should be focused performance tests, ideally testing a +single metric. Please never forget that these tests are synthetic and if you +are using them then you understand what metric is being tested.

It also has + the side effect of avoiding conflicts with common names that X already + uses such as Display, Screen, Window, etc. Note that when I refer to a + display below, I'm meaning a MetaDisplay and not a Display. + + Don't confuse displays and screens. While Metacity can run with multiple + displays, it is kind of useless since you might as well just run two + copies of Metacity. However, having multiple screens per display is + useful and increasingly common (known as "multiscreen" and "xinerama" + setups, where users make use of more than one monitor). You should + basically think of a display as a combination of one or more monitors + with a single keyboard (...and usually only one mouse). + + There is also a significant difference between multiscreen and xinerama + as well. Basically, each MetaScreen is a root window (root node in the + tree of windows). With Xinerama, a single root window appears to span + multiple monitors, whereas with multiscreen a root window is confined to + a single monitor. To re-emphasize the distinction between a display and + a screen, the pointer and keyboard are shared between all root windows + for a given display. + + The display keeps track of a lot of various global quantities, but in + particular has a compositor and a list (GList) of screens. + + A compositor is an opaque structure (only defined in compositor.c), + meaning that you'll only reference the API for it. It handles (or will + handle) cool stuff with the new X extensions, such as smooth resizing and + alpha transparency. + + A screen keeps track of a number of quantities as well, in particular a + stack and a list of workspaces. + + A stack is basically a list of windows, and the depth order they have + relative to each other (which thus determines which windows are on top + and which are obscured). + + A workspace mostly contains a list of windows for the workspace, but also + has a few other quantities as well (a list of struts which are areas + where windows should not be placed and an mru_list or "most recently used + window list"). + + A window has a huge list of quantities for keeping track of things about + a window on the screen. (We want to avoid making this list larger + because the memory for all these quantities is per window.) One item in + particular that a window has, though, is a frame. + + A frame is the decorations that surround the window (i.e. the titlebar and + the minimize and close buttons and the part that you can use to resize), + and contains a handful of variables related to that, but no other major + structures. + +Getting started -- where to look + Getting started on developing free software projects can often be like + being dropped off in a town that is unknown to you and being told to make + a map, when various road and building signs are missing or fading.

Some examples are when +a focused window is closed or minimized, or when the user changes +workspaces. In these cases, there needs to be a rule consistent with +the above about the new window to choose. + +Focus method Behavior + click Focus the window on top + sloppy Focus the window containing the pointer if there is such + a window, otherwise focus the most recently used window. + mouse Focus the non-DESKTOP window containing the pointer if + there is one, otherwise focus the designated + "no_focus_window". + +Note that "most recently used window", as used here, has a slightly +different connotation than "most recent to have keyboard focus". This +is because when a user activates a window that is a transient, its +ancestor(s) should be considered to be more recently used than other +windows that have had the keyboard focus more recently. (See bug +157360; this may mean that the alt-tab order should also change +simultaneously, although the current implementation does not do that.) + +Also, sometimes a new window will be mapped (e.g. unminimizing a +window or launching a new application). Most users want to interact +with new windows right away, so these should typically be focused. +This does conflict with the invariants for sloppy and mouse focus +modes, so this wouldn't be true for a strict-pointer-focus mode. For +all other modes (non-strict-pointer-focus modes), there are only two +cases in which a new window shouldn't be focused: + + 1) If the window takes a while to launch and the user starts + interacting with a different application, the new window should + not take focus. + 2) If the window that will appear was not launched by the user + (error dialogs, instant messaging windows, etc.), then the window + should not take focus when it appears. + +To handle these cases, Metacity compares timestamps of the event that +caused the launch and the timestamp of the last interaction with the +focused window. (Case 2 is handled by the application providing a +special timestamp of 0 for the launch time, which ensures that the +window that appears doesn't get focus) + +If the newly launched window isn't focused, some things should be done +to alert the user that there is a window to work with: + 1) The _NET_WM_DEMANDS_ATTENTION hint should be set + 2) If the new window isn't modal for the focused window, it should + appear below the focused window so that it doesn't obscure the + focused window that the user is interacting with. + 3) If the new window is modal to the focused window, the currently + focused window should lose focus but the modal window should + appear on top. + +Additionally, the user may decide to use the keyboard instead of the mouse +to navigate between windows (referred to as "keynav"). This poses no +problems for click-to-focus (because the same invariant can be +maintained), but for sloppy and mouse focus it requires extra work to +attempt to handle the INHERENTLY CONFLICTING CONSTRAINTS. Metacity does +this by having a mouse_mode boolean used to determine which of the two +sets of invariants holds. This mode is set according to which method was +most recently used to choose a focus window: + 1) When receiving EnterNotify events from mouse movement, set + mouse_mode to TRUE. + 2) When using keynav to choose a focus window (e.g. alt-tab, alt-esc, + alt-f2, move-window-to-workspace keybindings), set mouse_mode to FALSE. + 3) When handling events that don't choose a focus window but rather need + a focus_window chosen for them (e.g. switch-to-workspace keybindings), + don't change the mouse_mode and just use the current value. +Note that grabs present a special case since they can generate EnterNotify +and LeaveNotify events without using the mouse, thus these events should be +ignored when the crossing mode is NotifyGrab or NotifyUngrab. THIS +MOUSENAV/KEYNAV MODERATION METHOD IS NOT PERFECT--there are corner cases +when trying to mix-and-match between mousenav and keynav simultaneously +that cause problems; but it appears to be the most reasonable tradeoff and +works well in most cases, especially if the user sticks to just mousenav +for a long time or just keynav for a long time. + +Finally, windows of type WM_DOCK or WM_DESKTOP (e.g. the desktop and +the panel) present a special case, at least partially due to the lack +of decorations. For WM_DESKTOP windows, we only focus them if the +user explicitly requests it (e.g. clicks on the window, uses +Ctrl-Alt-Tab to navigate to it, uses a keybinding to show the desktop, +etc.).

This is what they mean by that: + + 1) Keynav doesn't maintain the same invariants as mouse navigation + for these focus modes; switching back and forth between + navigation methods, therefore, may have or appear to have + inconsistencies. Examples: + a) If the user uses Alt-Tab to change the window with focus, then + starts to move the mouse, at that moment the window where the + mouse is does not have focus. + b) Users expect that a workspace they previously used will not + change when the return to it. This means things like window + position and stacking order, but also the focus window. + Unfortunately, using the original focus window (which would be + the most recently used window on that workspace) will + sometimes conflict with the invariants for mouse and sloppy + focus modes. Users are much more surprised by the invariant + being broken than by having the focus window changed (see bug + 94545 and probably others), so we maintain the invariant. + This only matters when using Ctrl-Alt-Arrow to switch + workspaces instead of clicking in the workspace switcher, so + this really is a keynav vs mouse issue. Either that, or a + windows-are-being-mapped exception. ;-) + c) Opening a menu, then moving the mouse to a different window, + and then pressing escape to dismiss the menu will result in + the window containing the mouse not being focused. This is + actually correct behavior (because pressing escape shows that + the user is using key navigation to interact with the window + containing the menu) but is one of those hard-to-get-right + keynav and mouse focus mixture cases. (See bug 101190 for + more details) + d) Similar to (c), moving the mouse off the menu doesn't immediately + focus the window that the mouse goes over, due to an application + grab (we couldn't change this and wouldn't want to, but + technically it does break the invariant). + e) If mouse_mode is off and the user does something to cause focus to + change (e.g. switch workspaces, close or minimize a window, etc.) + and simultaneously tries to move the mouse, the choice of which + window to focus is inherently race-y. (You probably can't satisfy + both keynav and mousenav invariants simultaneously...) + 2) The sloppy/mouse invariants are often not strictly maintained; + for example, we provide an exception to the invariant for newly + mapped windows. (Most find that not allowing this exception is + confusing) + 3) There are an awful lot of little cases to handle to get any focus + mode right, even for click-to-focus. Since mouse and sloppy + focus have sometimes been hard to even determine what correct + behavior is, it is much harder to get them completely right. + Plus mouse and sloppy focus users are a minority, decreasing the + motivation of window manager implementors to get those focus + modes right. + 4) Because of -1-, -2-, and -3-, implementations are often buggy or + inconsistent and people form their opinions from usage of these + implementations. + 5) Sloppy focus suffers from a bit of a discoverability problem (for + example, I have seen a scientist sit down to a computer for which + sloppy focus was in use and take a few minutes before figuring + out how window activation worked; granted the layout of the + windows in that situation was a bit unusual but it still + illustrates that sloppy focus is harder than it should be to + figure out). Mouse focus solves this problem; however, people + that have experience with other computing environments are + accustomed to being able to move their mouse outside the window + they are working with and still continue interacting with that + window, which conflicts with mouse focus. diff --git a/doc/man/Makefile.am b/doc/man/Makefile.am new file mode 100644 index 0000000..088967f --- /dev/null

[\-\-sm\-disable] [\-\-sm\-save\-file=\fIFILENAME\fP] [\-\-version] [\-\-help] +.SH DESCRIPTION +This manual page documents briefly +.B mutter\fP. +.PP +.\" TeX users may be more comfortable with the \fB\fP and +.\" \fI\fP escape sequences to invode bold face and italics, +.\" respectively. +\fBmutter\fP is a minimal X window manager aimed at nontechnical users and is designed to integrate well with the GNOME desktop. \fBmutter\fP lacks some features that may be expected by traditional UNIX or other technical users; these users may want to investigate other available window managers for use with GNOME or standalone. +.SH OPTIONS +.TP +.B \-\-display=DISPLAY +Connect to X display \fIDISPLAY\fP. +.TP +.B \-\-replace +a window manager which is running is replaced by \fBmutter\fP.
