Gtk+ runs in a single thread, you must return to the mainloop that
you are running (in gtk_main()) in order for your callbacks to be called.
If you dont want to split up f1(); into iterations and run those short
iterations from a timeout function, then you might consider using GThread.
You can also use the old hack:
====================
while (gtk_events_pending ())
gtk_main_iteration ();
====================
to run the mainloop recursively so to speak, but if you never call
gtk_main_iteration() until you are finished f1(); then you are not
pushing progress bars.
