PopupMenu in JMenuItem

Question

Hi. I have a JMenu which has several JMenuItems added to it. When an item is right-clicked, I would like a JPopupMenu to be displayed. This can be done by creating a custom MenuUI and only firiing actions on left clicks and showing the popup menu on right-click.
The problem is that when the popup menu appears the underlying menu disappears, which I do not want to happen (I'm trying to achieve the effect of a favorites menu in a web browser where you can right click a favorite item and edit, delete, etc).
Does anyone have a good way to do this?
Thanks,
Jeff

This is the only way I can think of, but it's a nasty hack.
You can add your popup code in the else of the if in mousePressed.
setUI(new BasicMenuUI() {
    MouseInputListener listener;
    protected MouseInputListener createMouseInputListener(JComponent c) {
        listener = super.createMouseInputListener(c);
        return new MouseInputListener() {
            public void mouseClicked(MouseEvent e) {
                listener.mouseClicked(e);
            public void mousePressed(MouseEvent e) {
                if (!(e.getButton() == MouseEvent.BUTTON3))
                    listener.mousePressed(e);
            public void mouseReleased(MouseEvent e) {
                listener.mouseReleased(e);
            public void mouseEntered(MouseEvent e) {
                listener.mouseEntered(e);
            public void mouseExited(MouseEvent e) {
                listener.mouseExited(e);
            public void mouseDragged(MouseEvent e) {
                listener.mouseDragged(e);
            public void mouseMoved(MouseEvent e) {
                listener.mouseMoved(e);
});
