Ian now also it is failing why?

2 things:
a) You need to realize widgets before they can be drawn on. Doing a
gtk_widget_show_all on the toplevel window will do it for you, or you
can force it by calling gtk_widget_realize.
b) You can only do drawing in the expose_event callback otherwise it
won't show up.
