Constructor & Destructor Documentation

◆ WorkspaceScene()

KWin::WorkspaceScene::WorkspaceScene ( std::unique_ptr< ItemRenderer > renderer)
explicit

Definition at line 86 of file workspacescene.cpp.

◆ ~WorkspaceScene()

KWin::WorkspaceScene::~WorkspaceScene ( )
override

Definition at line 101 of file workspacescene.cpp.

Member Function Documentation

◆ animationsSupported()

virtual bool KWin::WorkspaceScene::animationsSupported ( ) const
pure virtual

Whether the Scene is able to drive animations. This is used as a hint to the effects system which effects can be supported. If the Scene performs software rendering it is supposed to return false, if rendering is hardware accelerated it should return true.

Implemented in KWin::WorkspaceSceneOpenGL, and KWin::WorkspaceSceneQPainter.
