Close JPanel and JDialog

Question

Hi.
I'm writing a software with one frame and in its contentPane in made up with two JPanel which changes continuously. The problem is that when I close that main frame the whole computer stops and seemes to enter into deadlock.
Can someone tell me which is the best method to close frames, dialogs and panels (I think it's the reason for my problem).
Now I'm using setVisible for panels and dialogs.
Thanks

Try something like :-
public class MyFrame
             extends JFrame
    public MyFrame()
        setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE);
        addWindowListener(new WindowAdapter()
            public void windowClosing(WindowEvent wndwEvnt)
                dispose();
                System.exit(0);
}There are other constants (e.g. WindowConstants.DISPOSE_ON_CLOSE if memory serves), that you can use depending on what you want to do when you 'close'.
