gtkmm treats dialogs differently to MFC. To access or change the value
stored in, say, a Gtk::Entry, you use the methods of the Gtk::Entry.
There are no widget variables or equivalents of the UpdateData() method.
So to get the text out of a Gtk::Entry, use entry.get_text(), and to put
it in, use entry.set_text(mystring).

Hope that helps.
