to_node

Returns the render node that was constructed by this.

Note that this function may return null if nothing has been added to the snapshot or if its content does not produce pixels to be rendered.

After calling this function, it is no longer possible to add more nodes to this. The only function that should be called after this is [method@GObject.Object.unref].

Parameters:

this	a `GtkSnapshot`

Returns:

the constructed `GskRenderNode` or null if there are no nodes to render.
