[gtkada] Drawing with gtkada

[Siddhartha Ray]

Hello,

 I am new to gtkada.

 I want to make a window with a drawing area where I can draw lines and
circles.

 I cannot figure out which class to use. I see there are 3 classes, namely,
gdk.drawable, gtk.drawing_area and gtk.canvas. Which one should I use? Also,
are there functions for drawing basic figures in gtkada?

Thanks,
-Sid
