I've tried adding:
app.addExitListener(new myExit());

Just after it, to see if I can get an ExitListener to catch it, using th=
e  =

following based on an example in the javadocs:

  class myExit implements Application.ExitListener {
       public boolean canExit(EventObject e) {
          Object source =3D (e !=3D null) ? e.getSource() : null;
          System.out.println("Canexit");
          Component owner =3D (source instanceof Component) ?  =

(Component)source : null;
          int option =3D JOptionPane.showConfirmDialog(owner, "Really Ex=
it?");
          return option =3D=3D JOptionPane.YES_OPTION;
      }
       public void willExit(EventObject e) {
       System.out.println("Willexit");
       }
  }

However, it's not working as far as I can tell. I did try putting it int=
o  =

the other class directly as an override to the shutdown() method of the =
 =

application, but couldn't get that to work either.
