When I wanted to prevent GtkEntry from handling the Return keypress, I
modified gtk_entry_key_press() as follows.  However, I believe that
mucking with the internal workings of widgets is frowned upon...


static gint
gtk_entry_key_press (GtkWidget   *widget,
		     GdkEventKey *event)
{
  ...
  switch (event->keyval)
  {
    ...
    case GDK_Return:
      /*
      return_val = TRUE;
      gtk_widget_activate (widget);
      */
      /* don't handle this event */
      return_val = FALSE;
      break;
    ...
  }
  ...
}
