    JPanel panel = new JPanel();
    final JLabel label = new JLabel(new Date().toString());
    panel.add(label);//  w  w  w.ja  v  a2s  .  c  om
    panel.addAncestorListener(new AncestorListener() {
        @Override
        public void ancestorAdded(AncestorEvent event) {
            // start animation
            label.setText(new Date().toString());
        }

        @Override
        public void ancestorRemoved(AncestorEvent event) {
            // stop animation
