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 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 ==(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.


def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def surface : Cairo::Surface #

Retrieves the Cairo surface used by the render node.
