All Implemented Interfaces:

QtObjectInterface

public abstract class QSGSimpleMaterialShader<State>
extends QSGMaterialShader

The QSGSimpleMaterialShader class provides a convenient way of building custom OpenGL-based materials for the scene graph.

Java wrapper for Qt class QSGSimpleMaterialShader

Warning: This utility class is only functional when running with the legacy OpenGL renderer of the Qt Quick scenegraph. Its usage is not recommended in new application code.

public QSGSimpleMaterialShader(Class<State> type)

Method Details

initialize

public void initialize()

Description copied from class: QSGMaterialShader

See QSGMaterialShader::initialize()

Overrides:

initialize in class QSGMaterialShader

uniformMatrixName

public final String uniformMatrixName()

Returns the name for the transform matrix uniform of this item. The default value is qt_Matrix.

See QSGSimpleMaterialShader::uniformMatrixName()const

uniformOpacityName

public final String uniformOpacityName()

Returns the name for the opacity uniform of this item. The default value is qt_Opacity.

See QSGSimpleMaterialShader::uniformOpacityName()const

updateState

public void updateState(QSGMaterialShader.RenderState state,
 QSGMaterial newMaterial,
 QSGMaterial oldMaterial)

Description copied from class: QSGMaterialShader

See QSGMaterialShader::updateState(QSGMaterialShader::RenderState,QSGMaterial*,QSGMaterial*)

Overrides:

updateState in class QSGMaterialShader

Parameters:

state -

newMaterial -

oldMaterial -

updateState

public abstract void updateState(State newState,
 State oldState)

Called whenever the state of this shader should be updated from oldState to newState, typical for each new set of geometries being drawn.

Both the old and the new state are passed in so that the implementation can compare and minimize the state changes when applicable.

See QSGSimpleMaterialShader::updateState(const State *, const State *)

resolveUniforms

public void resolveUniforms()

Reimplement this function to resolve the location of named uniforms in the shader program.

This function is called when the material shader is initialized.

See QSGSimpleMaterialShader::resolveUniforms()

attributes

public abstract List<String> attributes()

See QSGSimpleMaterialShader::attributes()const

attributeNames

public String[] attributeNames()

Description copied from class: QSGMaterialShader

See QSGMaterialShader::attributeNames()const

Specified by:

attributeNames in class QSGMaterialShader

Returns:
