that's the wrong aproach, you need to intercept the key event handling if
you handle up/down:


gtk_signal_connect (entry, "key_press_event", myf, NULL);
gint
myf (GtkWidget *widget, GdkEventKey *event, gpointer data)
{
  gboolean handled = FALSE;
  switch (event->keyval)
  {
  case GDK_Up:
  case GDK_Down:
    /* do something */
    handled = TRUE;
  }
  
  if (handled)
    gtk_signal_emit_stop_by_name (widget, "key_press_event");
  
  return handled;
}
