/** @defgroup kwineffects KWin effects library
|
|
* KWin effects library contains necessary classes for creating new KWin
|
|
* compositing effects.
|
|
*
|
|
* @section creating Creating new effects
|
|
* This example will demonstrate the basics of creating an effect. 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 macro
|
|
* To make KWin aware of your new effect, you first need to use the
|
|
* @ref KWIN_EFFECT macro to connect your effect's class to it's internal
|
|
* name. The internal name is used by KWin to identify your effect. It can be
|
|
* freely chosen (although it must be a single word), must be unique and won't
|
|
* be shown to the user. For our example, you would use the macro like this:
|
|
* @code
|
|
* KWIN_EFFECT(cooleffect, CoolEffect)
|
|
* @endcode
|
|
*
|
|
* @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.

* @short Base class for all KWin effects
|
|
*
|
|
* This is the base class for all effects. By reimplementing virtual methods
|
|
* of this class, you can customize how the windows are painted.
|
|
*
|
|
* The virtual methods are used for painting and need to be implemented for
|
|
* custom painting.
|
|
*
|
|
* In order to react to state changes (e.g. a window gets closed) the effect
|
|
* should provide slots for the signals emitted by the EffectsHandler.
|
|
*
|
|
* @section Chaining
|
|
* Most methods of this class are called in chain style. This means that when
|
|
* effects A and B area active then first e.g. A::paintWindow() is called and
|
|
* then from within that method B::paintWindow() is called (although
|
|
* indirectly). To achieve this, you need to make sure to call corresponding
|
|
* method in EffectsHandler class from each such method (using @ref effects
|
|
* pointer):
|
|
* @code
|
|
* void MyEffect::postPaintScreen()
|
|
* {
|
|
* // Do your own processing here
|
|
* ...
|
|
* // Call corresponding EffectsHandler method
|
|
* effects->postPaintScreen();
|
|
* }
|
|
* @endcode
|
|
*
|
|
* @section Effectsptr Effects pointer
|
|
* @ref effects pointer points to the global EffectsHandler object that you can
|
|
* use to interact with the windows.
|
|
*
|
|
* @section painting Painting stages
|
|
* Painting of windows is done in three stages:
|
|
* @li First, the prepaint pass.<br>
|
|
* Here you can specify how the windows will be painted, e.g. that they will
|
|
* be translucent and transformed.
|
|
* @li Second, the paint pass.<br>
|
|
* 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.<br>
|
|
* 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.
