{
    Timer t = new Timer()
    {
        public void run()
        {
            DOM.setStyleAttribute(getElement(), "backgroundColor", "white");
        }
    };
    public Demo()
    {
        setStyleName("table-center");
        setText("Mouse Over And Click");
        setSize("200px","200px");
        DOM.setStyleAttribute(getElement(), "textAlign", "center");
        DOM.setStyleAttribute(getElement(), "border", "5px solid #ddd");
        addMouseListener(this);
    }
    public void onMouseDown(Widget sender, int x, int y)
    {
        DOM.setStyleAttribute(getElement(), "borderColor", "#f00");
    }
    public void onMouseEnter(Widget sender)
    {
        DOM.setStyleAttribute(getElement(), "borderColor", "#0f0");
    }
    public void onMouseLeave(Widget sender)
    {
        DOM.setStyleAttribute(getElement(), "borderColor", "#ddd");
    }
    public void onMouseMove(Widget sender, int x, int y)
    {
        DOM.setStyleAttribute(getElement(), "backgroundColor", "yellow");
        t.schedule(300);
    }
    public void onMouseUp(Widget sender, int x, int y)
    {
        DOM.setStyleAttribute(getElement(), "borderColor", "#0f0");
