Renderer

abstract class Renderer(val gskRendererPointer: <Error class: unknown class><<Error class: unknown class>>)(source)

GskRenderer is a class that renders a scene graph defined via a tree of class@Gsk.RenderNode instances.

Typically you will use a GskRenderer instance to repeatedly call method@Gsk.Renderer.render to update the contents of its associated class@Gdk.Surface.

It is necessary to realize a GskRenderer instance using method@Gsk.Renderer.realize before calling method@Gsk.Renderer.render, in order to create the appropriate windowing system resources needed to render the scene.

Properties

gskRendererPointer

val gskRendererPointer: <Error class: unknown class><<Error class: unknown class>>

surface

open val surface: <Error class: unknown class>?

The surface associated with renderer.

Functions

isRealized

open fun isRealized(): Boolean

Checks whether the @renderer is realized or not.

realize

open fun realize(surface: <Error class: unknown class>? = null): <Error class: unknown class><Boolean>

Creates the resources needed by the @renderer to render the scene graph.

realizeForDisplay

open fun realizeForDisplay(display: <Error class: unknown class>): <Error class: unknown class><Boolean>

Creates the resources needed by the @renderer to render the scene graph.

render

open fun render(root: RenderNode, region: <Error class: unknown class>? = null)

Renders the scene graph, described by a tree of GskRenderNode instances to the renderer's surface, ensuring that the given @region gets redrawn.

renderTexture

open fun renderTexture(root: RenderNode, viewport: <Error class: unknown class>? = null): <Error class: unknown class>

Renders the scene graph, described by a tree of GskRenderNode instances, to a GdkTexture.

unrealize

open fun unrealize()

Releases all the resources created by gsk_renderer_realize().
