RenderNode

open class RenderNode(pointer: <Error class: unknown class><<Error class: unknown class>>)

GskRenderNode is the basic block in a scene graph to be rendered using class@Gsk.Renderer.

Each node has a parent, except the top-level node; each node may have children nodes.

Each node has an associated drawing surface, which has the size of the rectangle set when creating it.

Render nodes are meant to be transient; once they have been associated to a class@Gsk.Renderer it's safe to release any reference you have on them. All class@Gsk.RenderNodes are immutable, you can only specify their properties during construction.

Functions

getBounds

open fun getBounds(bounds: <Error class: unknown class>)

Retrieves the boundaries of the @node.

getNodeType

open fun getNodeType(): RenderNodeType

Returns the type of the @node.

ref

open fun ref(): RenderNode

Acquires a reference on the given GskRenderNode.

serialize

open fun serialize(): <Error class: unknown class>

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.

unref

open fun unref()

Releases a reference on the given GskRenderNode.

writeToFile

open fun writeToFile(filename: String): <Error class: unknown class><Boolean>

This function is equivalent to calling method@Gsk.RenderNode.serialize followed by func@GLib.file_set_contents.
