i trust you are doing this in a thread-safe manner.

i regret not knowing the gtkmm2 equivalent of this, but in gtk, its:

   gtk_main_iteration ();

you may want to follow that with:

   while (gtk_events_pending()) {
      gtk_main_iteration ();
   }

some people claim that this while loop by itself is enough; for
myself, i have seen cases where i think that gtk_events_pending()
returns false even though redraws are pending.
