GLShaderNode

A render node using a GL shader when drawing its children nodes.

Constructors

this
this(gsk.glshader.GLShader shader, graphene.rect.Rect bounds, glib.bytes.Bytes args, gsk.render_node.RenderNode[] children)

Creates a gsk.render_node.RenderNode that will render the given shader into the area given by bounds.

Members

Functions

getArgs
glib.bytes.Bytes getArgs()

Gets args for the node.

getChild
gsk.render_node.RenderNode getChild(uint idx)

Gets one of the children.

getNChildren
uint getNChildren()

Returns the number of children

getShader
gsk.glshader.GLShader getShader()

Gets shader code for the node.

Inherited Members

From RenderNode

deserialize
gsk.render_node.RenderNode deserialize(glib.bytes.Bytes bytes, gsk.types.ParseErrorFunc errorFunc)

Loads data previously created via gsk.render_node.RenderNode.serialize.

draw
void draw(cairo.context.Context cr)

Draw the contents of node to the given cairo context.

getBounds
void getBounds(graphene.rect.Rect bounds)

Retrieves the boundaries of the node.

getNodeType
gsk.types.RenderNodeType getNodeType()

Returns the type of the node.

serialize
glib.bytes.Bytes serialize()

Serializes the node for later deserialization via gsk.render_node.RenderNode.deserialize. No guarantees are made about the format used other than that the same version of GTK will be able to deserialize the result of a call to gsk.render_node.RenderNode.serialize and gsk.render_node.RenderNode.deserialize will correctly reject files it cannot open that were created with previous versions of GTK.

writeToFile
bool writeToFile(string filename)

This function is equivalent to calling gsk.render_node.RenderNode.serialize followed by funcGLib.file_set_contents.
