Member Function Documentation

frame()

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

overridevirtual

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

Reimplemented from KWin::RenderLayerDelegate.

Definition at line 47 of file scene.cpp.

output()

Output * KWin::SceneDelegate::output

(

)

const

Definition at line 52 of file scene.cpp.

paint()

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

overridevirtual

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

Implements KWin::RenderLayerDelegate.

Definition at line 42 of file scene.cpp.

postPaint()

void KWin::SceneDelegate::postPaint ( )

overridevirtual

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

Reimplemented from KWin::RenderLayerDelegate.

Definition at line 37 of file scene.cpp.

prePaint()

QRegion KWin::SceneDelegate::prePaint ( )

overridevirtual

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

Reimplemented from KWin::RenderLayerDelegate.

Definition at line 32 of file scene.cpp.

scale()

qreal KWin::SceneDelegate::scale

(

)

const

Definition at line 57 of file scene.cpp.

scanoutCandidate()

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

overridevirtual

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

Reimplemented from KWin::RenderLayerDelegate.

Definition at line 27 of file scene.cpp.

viewport()

QRect KWin::SceneDelegate::viewport

(

)

const
