Member Function Documentation

frame()

void KWin::RenderLayerDelegate::frame ( OutputFrame * frame )

virtual

This function is called by the compositor after compositing the frame.

Reimplemented in KWin::SceneDelegate.

Definition at line 22 of file renderlayerdelegate.cpp.

layer()

RenderLayer * KWin::RenderLayerDelegate::layer

const

paint()

virtual void KWin::RenderLayerDelegate::paint ( const RenderTarget & renderTarget, const QRegion & region )

pure virtual

This function is called when the compositor wants the render layer delegate to repaint its contents.

Implemented in KWin::CursorDelegateOpenGL, KWin::CursorDelegateQPainter, and KWin::SceneDelegate.

postPaint()

void KWin::RenderLayerDelegate::postPaint ( )

virtual

This function is called by the compositor after finishing painting. Reimplement this function to do post frame cleanup.

Reimplemented in KWin::SceneDelegate.

Definition at line 31 of file renderlayerdelegate.cpp.

prePaint()

QRegion KWin::RenderLayerDelegate::prePaint ( )

virtual

This function is called by the compositor before starting painting. Reimplement this function to do frame initialization.

Reimplemented in KWin::SceneDelegate.

Definition at line 26 of file renderlayerdelegate.cpp.

scanoutCandidate()

SurfaceItem * KWin::RenderLayerDelegate::scanoutCandidate ( ) const

virtual

Returns the direct scanout candidate hint. It can be used to avoid compositing the render layer.

Reimplemented in KWin::SceneDelegate.

Definition at line 35 of file renderlayerdelegate.cpp.

setLayer()

void KWin::RenderLayerDelegate::setLayer
