Detailed Description

GlRenderValueBinding is a binding from shaders/materials into values in GlRenderState.

Since: Kanzi 3.9.7 removed applyBlendMode(). Use getBlendModeValue() instead.; Kanzi 3.9.9 removed setBlendModeFallback().

Member Function Documentation

◆ addPropertyListener()

void kanzi::GlRenderValueBinding::addPropertyListener	(	Node *	node,
		GlRenderState &	renderState,
		PropertyDataType	dataType,
		AbstractPropertyType	propertyType,
		ShaderProgram::UniformTransformation	transformation )

Add a listener for given property.

Parameters

node	Node on which to listen for property changes.
renderState	Render state to update when the property changes.
dataType	Data type of the render value.
propertyType	Property type to listen.
transformation	Shader transformation for uniform values.

Since: Kanzi 3.9.7 added dataType.

◆ attach() [1/2]

void kanzi::GlRenderValueBinding::attach	(	Material &	material,
		Node *	node,
		bool	readBlendModeFromNode,
		GlRenderState &	renderState )

Attaches to a material and a node.

When used with 2D nodes, the blend mode control is not necessarily attached to the node. This is the case when the blend mode is determined manually.

Parameters

material	Material to use.
node	Node to listen property changes on or nullptr.
readBlendModeFromNode	If you want to read the blend mode from the node, set to true.
renderState	The render state to update on changes.

Since: Kanzi 3.9.1

◆ attach() [2/2]

void kanzi::GlRenderValueBinding::attach	(	Material &	material,
		Node *	node,
		GlRenderState &	renderState )

inline

Attaches to a material and a node.

Reading the blend mode from the node is enabled.

Parameters

material	Material to use.
node	Node to listen property changes on or nullptr.
renderState	The render state to update on changes.

◆ update()

void kanzi::GlRenderValueBinding::update	(	GlRenderState &	renderState,
		PropertyObject *	object,
		Material &	material )

Apply changes into render state.

Parameters

renderState	Render state to write changes to.
object	Fallback property object for property value.
material	Fallback material for property value.

Since: Kanzi 3.9.1 data type of object parameter changed from Object* to PropertyObject*.

◆ invalidate()

void kanzi::GlRenderValueBinding::invalidate ( )

Invalidates the state of the notification handler.

Use this function to invalidate a node that you destroyed before destroying the GlRenderValueBinding.

◆ setAllPropertiesDirty()

void kanzi::GlRenderValueBinding::setAllPropertiesDirty ( )

Flag all properties as being dirty and needing an update.

◆ getBlendModeValue()

optional< int > kanzi::GlRenderValueBinding::getBlendModeValue	(	PropertyObject *	object,
		Material &	material ) const

Gets the blend mode value to apply.

Kanzi uses this function internally by calling it in applyBlendMode(). You can use this function in tests.

Parameters

object	Object to use for acquiring the property.
material	Current material.

Since: Kanzi 3.9.7; Kanzi 3.9.9 made the function const.

◆ applyBlendMode()

void kanzi::GlRenderValueBinding::applyBlendMode	(	GlRenderState &	renderState,
		PropertyObject *	object,
		Material &	material )

Applies the blend mode.

Parameters

renderState	The render state to which to write.
object	Object to use for acquiring the property.
material	Current material.

Since: Kanzi 3.9.1

◆ setBlendModeOverride()

void kanzi::GlRenderValueBinding::setBlendModeOverride ( optional< int > blendMode )

inline

Sets the blend mode override.

This should be the blend mode as determined by the layout system, originally coming from node.

Parameters

blendMode Blend mode override or nullopt to disable.

Since: Kanzi 3.9.1

◆ getBlendModeOverride()

optional< int > kanzi::GlRenderValueBinding::getBlendModeOverride ( ) const

inline

Gets the blend mode override.

This function is intended for tests.

Returns: Blend mode override.

Since: Kanzi 3.9.9

◆ setTranslucencyHint()

void kanzi::GlRenderValueBinding::setTranslucencyHint ( bool value )

inline

Sets the translucency hint.

Translucency hint should be set by the brush depending on the content requirements.

Parameters

value Translucency hint value.

Since: Kanzi 3.9.9

◆ getTranslucencyHint()

bool kanzi::GlRenderValueBinding::getTranslucencyHint ( ) const

inline

Gets the translucency hint.

This function is intended for tests.

Returns: Translucency hint value.

Since: Kanzi 3.9.9

◆ setOpaquenessHint()

void kanzi::GlRenderValueBinding::setOpaquenessHint ( bool value )

inline

Sets the opaqueness hint.

Should be set if external factors allow for opaque rendering.

Parameters

value Opaqueness hint value.

Since: Kanzi 3.9.9

◆ getOpaquenessHint()

bool kanzi::GlRenderValueBinding::getOpaquenessHint ( ) const

inline

Gets the opaqueness hint.

This function is intended for tests.

Returns: Opaqueness hint value.

Since: Kanzi 3.9.9
