Functions

draw

open fun draw(cr: <Error class: unknown class>)

Draw the contents of @node to the given cairo context.

getBounds

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

Retrieves the boundaries of the @node.

getDrawContext

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

Creates a Cairo context for drawing using the surface associated to the render node.

getNodeType

open fun getNodeType(): RenderNodeType

Returns the type of the @node.

getSurface

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

Retrieves the Cairo surface used by the render 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.
