Creates a gsk.render_node.RenderNode that will drawn the child with reduced opacity.
Gets the child node that is getting opacityed by the given node.
Gets the transparency factor for an opacity node.
Loads data previously created via gsk.render_node.RenderNode.serialize.
Draw the contents of node to the given cairo context.
Retrieves the boundaries of the node.
Returns the type of the node.
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.
This function is equivalent to calling gsk.render_node.RenderNode.serialize followed by funcGLib.file_set_contents.
A render node controlling the opacity of its single child node.
