Sorry, but I don't see how this is related to GTK+ documentation
(which is what this thread is all about).

I don't think a drawing area is the right kind of widget to use
here. Actually I doubt that GtkDrawingArea is particulary useful for
any purpose at all. The fact that it has it's own INPUT/OUTPUT window
makes it rather inefficient and I expect it to be deprecated at some
point.

Did you look at GnomeCanvas or similar implementations?
