Hey everyone,

This is a simple question, or at least, it should be :). I need a Timer to start when a JDialog opens and stop when it closes so a cute icon animation shows.

So far, I managed to detect when the window opens, but not when it closes. This code is at the JDialog constructor:

addWindowListener(new WindowAdapter()
        {
            @Override
            public void windowClosed(WindowEvent we)
            {
                System.out.println("\t\t\t\twindowClosed");
                busyIconTimer.stop();
            }

            @Override
            public void windowOpened(WindowEvent we)
            {
                System.out.println("\t\t\t\twindowOpened");
                busyIconTimer.start();
            }
        });

When I call "setVisible(true)", the windowClosed event is raised.
When I call "setVisible(false", no event is called whatsoever (tried all the events available).
Instead, if I call "mydialog.dispose()", the windowClosed event is called correctly.
But after this, if I call "setVisible(true)" again, the windowOpened isn't called.

Can anyone help me? :)

Thanks in advance.
