Pixelbuffer to draw on a surface

[TheDGuy via Digitalmars-d-learn]

Thanks for your answers. I think Cairo is the right way but i 
have a hard time to translate any of those C++ or Python 
tutorials to D, my current code:

import gtk.Main;
import gtk.MainWindow;
import gtk.DrawingArea;
import gdk.Cairo;
import gtk.Widget;

void main(string[] args){
	Main.init(args);
	MainWindow win = new MainWindow("Tutorial");
	win.setDefaultSize(250,250);

	win.add(new MyArea());
	win.showAll();
	Main.run();
}

class MyArea : DrawingArea
{
	this(){
	}

	bool on_draw(){

		return true;
	}
}

I tried to work with this Python tutorial (i think Python is 
easier to read than C++):

but if i try to do this: "cr = self.window.cairo_create()" i get:
"No property Window for type main.Area"?
