Constructor Detail

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

Creates a GskRenderNode 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 self.new #

Initialize a new CairoNode.


Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

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.


def surface : Cairo::Surface #

Retrieves the Cairo surface used by the render node.
