Thanks a lot
I shall put all my drawings in the expose event and try my application again.
I had taken the sample program form GdkRGB chapter (gdk API Reference) and was trying
it the other way round .
So whenever I want some drawings to happen in my drawable I should better call
a gtk_widget_queue_draw_area() or gdk_window_invalidate_rect() and do all the
drawing in the expose event callback .
Please correct me if I have understood it wrongly
