    JList<String> myJList = new JList(items) {
      @Override
      protected void processMouseEvent(MouseEvent e) {
        int modifiers = e.getModifiers() | InputEvent.CTRL_MASK;
        int modifiersEx = e.getModifiersEx() | InputEvent.CTRL_MASK;
        MouseEvent myME = new MouseEvent((Component) e.getSource(), e.getID(),
            e.getWhen(), modifiers, e.getX(), e.getY(), e.getXOnScreen(),
            e.getYOnScreen(), e.getClickCount(), e.isPopupTrigger(),
            e.getButton());
        super.processMouseEvent(myME);
      }

    JFrame f = new JFrame();
    f.add(new JScrollPane(myJList));
