Comment 18 for bug 16492

I had a look at this today, scrolling through pages of gtk & gdk stuff. I have tried coding up a potential solution, and the preliminary patch is attached. Please note, it is just an experiment, and has not been tested in any way, it was just to see where I could solve the problem.

I think that it would be good for gtkwidget to have the main implementation which would then be inherited everywhere, but widgets need to be able to override it. Thus the patch needs more work so gtktextview and gtkentry can replace the gtkwidget implementation with their own.
