In my opinion, the "pygtk way" if there is such a thing, is to make
greater use of signals father than function callbacks explicitly. The
following pseudocode might give you some ideas;
class OtherW(gtk.Window)
def get_data_user_entered(self):
return 42
class W(gtk.Window):
def user_clicked_button(self):
self.ow = OtherW()
self.ow.button.connect("clicked", self._get_data)
def _get_data(self, *args):
data = self.ow.get_data_user_entered()
w = W()
w.show_all()
gtk.main()
