I have had the most trouble closing my Frames. I know the Frame ignores the Event.WINDOW_DESTROY. So without using System.exit(0), how can I get my Frames to close?

Call the frames dispose() method.

dispose() destroys the frame. If thats not what you want, then you can call its diasable(true)  and setVisible(false) methods.

Thanks for the quick reply.

Your I have tried your suggestions. Here is the code that I thought would do the job; however, when I hit the 'X' in Win 95 to close the frame nothing happens.

Thanks

 public boolean handleEvent(Event event)
  {  
      if (event.id == Event.WINDOW_DESTROY)
      {
            hide();         // hide the Frame
            dispose();      // free the system resources
            System.exit(0); // close the application
            return true;
      }
      return super.handleEvent(event);
   }

Since a Frame is derived from Window, which is derived from container which is derived from component, you might want to try:

YourFrame.getParrent().remove(YourFrame);

and see if that works.
