Overview

A render node that potentially diverts a part of the scene graph to a subsurface.

Class Method Summary

• .get_subsurface(node) ⇒ GObject

  Gets the subsurface that was set on this node.

Instance Method Summary

• #child ⇒ Gsk::RenderNode

  Gets the child node that is getting drawn by the given node.

• #initialize(child, subsurface) ⇒ Gsk::SubsurfaceNode constructor

  Creates a GskRenderNode that will possibly divert the child node to a subsurface.

Constructor Details

#initialize(child, subsurface) ⇒ Gsk::SubsurfaceNode

Creates a GskRenderNode that will possibly divert the child node to a subsurface.

Note: Since subsurfaces are currently private, these nodes cannot currently be created outside of GTK. See GtkGraphicsOffload.

Parameters:

• child (Gsk::RenderNode) —

  The child to divert to a subsurface

• subsurface (GObject) —

  the subsurface to use

Class Method Details

.get_subsurface(node) ⇒ GObject

Gets the subsurface that was set on this node

Parameters:

• node (Gsk::DebugNode) —

  a debug GskRenderNode

Returns:

• (GObject) —

  the subsurface

Instance Method Details

#child ⇒ Gsk::RenderNode

Gets the child node that is getting drawn by the given node.

Returns:

• (Gsk::RenderNode) —

  the child GskRenderNode
