Constructor Detail

def self.new(bounds : Graphene::Rect) : self #

Creates a Gsk::RenderNode that will render a cairo surface into the area given by bounds.

You can draw to the cairo surface using Gsk::CairoNode#draw_context.

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def draw_context : Cairo::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.
