We'll use * CoolEffect as the class name, cooleffect as internal name and * "Cool Effect" as user-visible name of the effect. * * This example doesn't demonstrate how to write the effect's code. For that, * see the documentation of the Effect class. * * @subsection creating-class CoolEffect class * First you need to create CoolEffect class which has to be a subclass of * @ref KWin::Effect. In that class you can reimplement various virtual * methods to control how and where the windows are drawn. * * @subsection creating-macro KWIN_EFFECT_FACTORY macro * This library provides a specialized KPluginFactory subclass and macros to * create a sub class. This subclass of KPluginFactory has to be used, otherwise * KWin won't load the plugin. Use the @ref KWIN_EFFECT_FACTORY macro to create the * plugin factory. * * @subsection creating-buildsystem Buildsystem * To build the effect, you can use the KWIN_ADD_EFFECT() cmake macro which * can be found in effects/CMakeLists.txt file in KWin's source. First * argument of the macro is the name of the library that will contain * your effect. Although not strictly required, it is usually a good idea to * use the same name as your effect's internal name there. Following arguments * to the macro are the files containing your effect's source. If our effect's * source is in cooleffect.cpp, we'd use following: * @code * KWIN_ADD_EFFECT(cooleffect cooleffect.cpp) * @endcode * * This macro takes care of compiling your effect. You'll also need to install * your effect's .desktop file, so the example CMakeLists.txt file would be * as follows: * @code * KWIN_ADD_EFFECT(cooleffect cooleffect.cpp) * install( FILES cooleffect.desktop DESTINATION ${SERVICES_INSTALL_DIR}/kwin ) * @endcode * * @subsection creating-desktop Effect's .desktop file * You will also need to create .desktop file to set name, description, icon * and other properties of your effect. Important fields of the .desktop file * are: * @li Name User-visible name of your effect * @li Icon Name of the icon of the effect * @li Comment Short description of the effect * @li Type must be "Service" * @li X-KDE-ServiceTypes must be "KWin/Effect" * @li X-KDE-PluginInfo-Name effect's internal name as passed to the KWIN_EFFECT macro plus "kwin4_effect_" prefix * @li X-KDE-PluginInfo-Category effect's category. Should be one of Appearance, Accessibility, Window Management, Demos, Tests, Misc * @li X-KDE-PluginInfo-EnabledByDefault whether the effect should be enabled by default (use sparingly). Default is false * @li X-KDE-Library name of the library containing the effect. This is the first argument passed to the KWIN_ADD_EFFECT macro in cmake file plus "kwin4_effect_" prefix. * * Example cooleffect.desktop file follows: * @code [Desktop Entry] Name=Cool Effect Comment=The coolest effect you've ever seen Icon=preferences-system-windows-effect-cooleffect Type=Service X-KDE-ServiceTypes=KWin/Effect X-KDE-PluginInfo-Author=My Name X-KDE-PluginInfo-Email=my@email.here X-KDE-PluginInfo-Name=kwin4_effect_cooleffect X-KDE-PluginInfo-Category=Misc X-KDE-Library=kwin4_effect_cooleffect * @endcode * * * @section accessing Accessing windows and workspace * Effects can gain access to the properties of windows and workspace via * EffectWindow and EffectsHandler classes. * * There is one global EffectsHandler object which you can access using the * @ref effects pointer. * For each window, there is an EffectWindow object which can be used to read * window properties such as position and also to change them. * * For more information about this, see the documentation of the corresponding * classes. * * @{ **/ #define KWIN_EFFECT_API_MAKE_VERSION( major, minor ) (( major ) << 8 | ( minor )) #define KWIN_EFFECT_API_VERSION_MAJOR 0 #define KWIN_EFFECT_API_VERSION_MINOR 224 #define KWIN_EFFECT_API_VERSION KWIN_EFFECT_API_MAKE_VERSION( \ KWIN_EFFECT_API_VERSION_MAJOR, KWIN_EFFECT_API_VERSION_MINOR ) enum WindowQuadType { WindowQuadError, // for the stupid default ctor WindowQuadContents, WindowQuadDecoration, // Shadow Quad types WindowQuadShadow, // OpenGL only.

* Here you can specify how the windows will be painted, e.g. that they will * be translucent and transformed. * @li Second, the paint pass.
* Here the actual painting takes place. You can change attributes such as * opacity of windows as well as apply transformations to them. You can also * paint something onto the screen yourself. * @li Finally, the postpaint pass.
* Here you can mark windows, part of windows or even the entire screen for * repainting to create animations. * * For each stage there are *Screen() and *Window() methods. The window method * is called for every window which the screen method is usually called just * once. * * @section OpenGL * Effects can use OpenGL if EffectsHandler::isOpenGLCompositing() returns @c true. * The OpenGL context may not always be current when code inside the effect is * executed. The framework ensures that the OpenGL context is current when the Effect * gets created, destroyed or reconfigured and during the painting stages.
