Hi all,

I need to know how to close an applet window that is running off an applet.   It is called from the applet.  I have tried the following from a class called

class VehicleMaintenance extends Applet
   implements ActionListener {
...........

if (source == button1 ) {
          Frame f = new Frame("Rent-Ur-Wheels");
          VehicleRental vR = new VehicleRental();
          f.add(vR);
          f.setSize(300, 100);
          f.show();
          WindowListener l =
                    new WindowAdapter() {
                             public void windowClosing(WindowEvent e) {
                         System.exit(0);
                  }
               };
        f.addWindowListener(l);
}

...........
}
but that does not seem to close the window down at all.  It displays the window and its contents of the VehicleRental Class - class VehicleRental extends Panel{...} , minimises and maximises but wont close.

Can someone help please
Thanks.

ovi - ty but it did not work - the compiler gives me errors to say
Attempt to use a non-final variable f from a different method.From enclosing blocks only final local varibles are available

In my original post was like this :
final Frame f = new Frame("Rent-Ur-Wheels");

this meens the f variable is final and you will not get any errors.
