Creates a new GskRenderNode instance for holding the given children.
The new node will acquire a reference to each of the children.
The children of the node
Draw the contents of node to the given cairo context.
Typically, you'll use this function to implement fallback rendering
of GskRenderNodes on an intermediate Cairo context, instead of using
the drawing context associated to a [classGdk.Surface]'s rendering buffer.
For advanced nodes that cannot be supported using Cairo, in particular for nodes doing 3D operations, this function may fail.
Gets one of the children of container.
the position of the child to get
Retrieves the number of direct children of node.
Returns the type of the node.
Acquires a reference on the given GskRenderNode.
Serializes the node for later deserialization via
gsk_render_node_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_serialize() and
gsk_render_node_deserialize() will correctly reject files it cannot open
that were created with previous versions of GTK.
The intended use of this functions is testing, benchmarking and debugging. The format is not meant as a permanent storage format.
Releases a reference on the given GskRenderNode.
If the reference was the last, the resources associated to the node are
freed.
This function is equivalent to calling [methodGsk.RenderNode.serialize]
followed by [funcGLib.file_set_contents].
See those two functions for details on the arguments.
It is mostly intended for use inside a debugger to quickly dump a render node to a file for later inspection.
the file to save it to.
Loads data previously created via [methodGsk.RenderNode.serialize].
For a discussion of the supported format, see that function.
the bytes containing the data
Creates a new GskRenderNode instance for holding the given children.
The new node will acquire a reference to each of the children.
The children of the node
A render node that can contain other render nodes.
