/**
|
|
* @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 of this class can broadly be divided into two
|
|
* categories: the methods used for painting and those you can use to be
|
|
* notified and react to certain events, e.g. that a window was closed.
|
|
*
|
|
* @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.
