Module Gtk_cairo.Gtk_cairo

module Gtk_cairo: sig .. end

An implementation of Renderer using GTK+ and cairo2 as the backend. This is the main renderer that supports all p5ml features.

type buffer = {
   window : GWindow.window;
   draw : GMisc.drawing_area;
   shape : Shape.t Stdlib.ref;
   surface : Cairo.Surface.t Stdlib.ref;
   context : Cairo.context Stdlib.ref;
   events : Renderer.event Stdlib.Queue.t;
   mutex : Mutex.t;
}

clear buffer does not modify the buffer. This is because the Cairo surface gets cleared every frame automatically.
