Hey, try using

while (Gtk::Main::events_pending())  Gtk::Main::iteration();

To handle all pending gui events, before proceeding to next loop.

Remember that your code executes when gtkmm calls your event handlers, not the other way around. Under normal circumstances, state changes to widgets will not cause screen updates until your event handler returns control to gtkmm. You can give gtkmm a chance to execute by inserting 

while(Gtk::Main::events_pending())
                Gtk::Main::iteration();

into your loop.
