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?
