Methods

• SubsurfaceNode (child = null, subsurface = null)

  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.

  • @p child is The child to divert to a subsurface.
  • @p subsurface is the subsurface to use.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asRenderNode ()

  Wraps this handle as RenderNode.

  • @r A RenderNode object.

• get_child ()

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