I think your suspicion was correct. This works, although I am not sure 
whether this is how it should be done:

         self.DA = Preview()
         self.widget('box_preview').pack_start(self.DA.da, True, True, 0)
         while Gtk.events_pending():
             Gtk.main_iteration()
         self.draw_note(self.DA.da, self.DA.surface)

What is a bit odd, however, is that if I move the Gtk.main_iteration() 
to the __init__ or the configuration function, then it doesn't work.
Anyway, I would still be interested in the "proper" way of handling this.
Cheers,
Zoltán
