Member Function Documentation

◆ isActive()

bool KWin::InvertEffect::isActive ( ) const

overridevirtual

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.

Since: 4.8

Reimplemented from KWin::Effect.

Definition at line 153 of file invert.cpp.

◆ loadData()

bool KWin::InvertEffect::loadData ( )

protected

Definition at line 93 of file invert.cpp.

◆ provides()

bool KWin::InvertEffect::provides ( Feature )

overridevirtual

Called on Transparent resizes. return true if your effect substitutes questioned feature

Reimplemented from KWin::Effect.

Definition at line 158 of file invert.cpp.

◆ requestedEffectChainPosition()

int KWin::InvertEffect::requestedEffectChainPosition ( ) const

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.

Since: 5.0
