I can think of one example where it could be useful.
I think I read about it in one of the books. The book called "Visual C++ MFC
Programming by Example".
I'm talking about dynamically filling the combo box.
I can catch the "notification:popdown/popup" signal, but if I want to
write a unit
test for this I should be able to imitate this behaviour programmatically.
Now in case the user of my program is disabled there is a special library
I can link with and use that will allow to work with such features of GTK+.

Am I right?

Thank you.
