class QSGMaterialShader::RenderState

The QSGMaterialShader::RenderState encapsulates the current rendering state during a call to QSGMaterialShader::updateState(). More...

Public Types

enum	DirtyState { DirtyMatrix, DirtyOpacity, DirtyCachedMaterialData, DirtyAll }

The render state contains a number of accessors that the shader needs to respect in order to conform to the current state of the scene graph.

The instance is only valid inside a call to QSGMaterialShader::updateState() and should not be used outisde this function.
