The problem in JComboBox, help!

Question

Hi,
My case is to forbid the users using Up and Down arrow key to access items in the list, but they can still use mouse to access items.
But after I tried several ways, I still can't achieve that. I am using a editable comboBox. So, even my focus is in JTextField, when I press Up and Down arrow keys, the item list was still displayed on the screen. I don't want them appear, but only with mouse at that time.
Does anybody know how to fix that?
Many Thanks!
Feng

Try this code.

JComboBox cb;
        KeyStroke ks = KeyStroke.getKeyStroke(KeyEvent.VK_UP, 0);
        cb.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(ks, "MoveUp");
        cb.getActionMap().put("MoveUp", new AbstractAction() {
            public void actionPerformed(ActionEvent e) {
                System.out.println("up key pressed");
        ks = KeyStroke.getKeyStroke(KeyEvent.VK_DOWN, 0);
        cb.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(ks, "MoveDown");
        cb.getActionMap().put("MoveDown", new AbstractAction() {
            public void actionPerformed(ActionEvent e) {
                System.out.println("down key pressed");
        });
