Try the following code from Owen Taylor :

--------
void
event_box_state_changed (GtkWidget *w)
{
  if (w->state == GTK_STATE_NORMAL)
    gdk_window_set_background (w->window, &w->style->white);
  else
    gdk_window_set_background (w->window, &w->style->bg[w->state]);

  if (GTK_WIDGET_DRAWABLE(w))
      gdk_window_clear_area (w->window, 0, 0, 
                             w->allocation.width, w->allocation.height);
}

  event_box = gtk_event_box_new ();

  gtk_signal_connect(GTK_OBJECT(event_box), "state_changed",
                     GTK_SIGNAL_FUNC (event_box_state_changed), NULL);
  gtk_signal_connect(GTK_OBJECT(event_box), "realize",
                     GTK_SIGNAL_FUNC (event_box_state_changed), NULL);

  ... show the listbox, fill in contents  ...

That worked for me ! ;)
