|
inlineoverridevirtual |
Overwrite this method to indicate whether your effect will be doing something in the next frame to be rendered. If the method returns false the effect will be excluded from the chained methods in the next rendered frame.
This method is called always directly before the paint loop begins. So it is totally fine to e.g. react on a window event, issue a repaint to trigger an animation and change a flag to indicate that this method returns true.
As the method is called each frame, you should not perform complex calculations. Best use just a boolean flag.
The default implementation of this method returns true.

- 4.8
Reimplemented from KWin::Effect.
◆ paintScreen()
|
overridevirtual |
In this method you can:
- paint something on top of the windows (by painting after calling effects->paintScreen())
- paint multiple desktops and/or multiple copies of the same desktop by calling effects->paintScreen() multiple times
In OpenGL based compositing, the frameworks ensures that the context is current when this method is invoked.
Reimplemented from KWin::Effect.
◆ paintWindow()
|
overridevirtual |
This is the main method for painting windows. In this method you can:
- do various transformations
- change opacity of the window
- change brightness and/or saturation, if it's supported
In OpenGL based compositing, the frameworks ensures that the context is current when this method is invoked.
Reimplemented from KWin::Effect.
◆ postPaintScreen()
|
overridevirtual |
Called after all the painting has been finished. In this method you can:
- schedule next repaint in case of animations You shouldn't paint anything here.
In OpenGL based compositing, the frameworks ensures that the context is current when this method is invoked.
Reimplemented from KWin::Effect.
◆ prePaintScreen()
|
overridevirtual |
Called before starting to paint the screen. In this method you can:
- set whether the windows or the entire screen will be transformed
- change the region of the screen that will be painted
- do various housekeeping tasks such as initing your effect's variables for the upcoming paint pass or updating animation's progress
presentTime specifies the expected monotonic time when the rendered frame will be displayed on the screen.
Reimplemented from KWin::Effect.
◆ prePaintWindow()
|
overridevirtual |
Called for every window before the actual paint pass In this method you can:
- enable or disable painting of the window (e.g. enable paiting of minimized window)
- set window to be painted with translucency
- set window to be transformed
- request the window to be divided into multiple parts
In OpenGL based compositing, the frameworks ensures that the context is current when this method is invoked.
presentTime specifies the expected monotonic time when the rendered frame will be displayed on the screen.
Reimplemented from KWin::Effect.
◆ reconfigure()
|
overridevirtual |
Called when configuration changes (either the effect's or KWin's global).
In OpenGL based compositing, the frameworks ensures that the context is current when the Effect is reconfigured. If this method is called from within the Effect it is required to ensure that the context is current if the implementation does OpenGL calls.
Reimplemented from KWin::Effect.
◆ requestedEffectChainPosition()
|
inlineoverridevirtual |
Reimplement this method to indicate where in the Effect chain the Effect should be placed.
A low number indicates early chain position, thus before other Effects got called, a high number indicates a late position. The returned number should be in the interval [0, 100]. The default value is 0.
In KWin4 this information was provided in the Effect's desktop file as property X-KDE-Ordering. In the case of Scripted Effects this property is still used.
