The for-loop prevents the GTK+ main loop from handling the update
events, so no updating will happen. On way is to do this inside the
for-loop

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

but this is not as nice as using g_timeout_add() or even g_idle_add()
for implementing animation.

Generally speaking, running the main loop by hand brings more problems
than solutions, so one should always use g_timout_add() or similar
mainloop integration to implement this kind of constant updates.
