Methods

• CairoNode (bounds = null)

  Creates a GskRenderNode that will render a cairo surface into the area given by @bounds. You can draw to the cairo surface using [method@Gsk.CairoNode.get_draw_context].

  • @p bounds is the rectangle to render to.

• 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_draw_context ()

  Creates a Cairo context for drawing using the surface associated to the render node. If no surface exists yet, a surface will be created optimized for rendering to @renderer.

• get_surface ()

  Retrieves the Cairo surface used by the render node.
