Dialog::run() returns an int which is a value representing which button 
was pressed. In this case (where you're using Gtk::BUTTONS_YES_NO), 
you're going to get either Gtk::RESPONSE_YES or Gtk::RESPONSE_NO. Other 
such things for different buttons would include Gtk::RESPONSE_CANCEL, 
Gtk::RESPONSE_OK and so forth.
Please read the book:

specifically in this case the on_button_question_clicked() function
