SWT How to:添加系統托盤

　　添加系統托盤的核心code：

         final ImageData trayIcon = new ImageData(SWTSystemTray.class.

                getResource("/resources/16x16/tray.png").getPath());

        final Image trayImage = new Image(display, trayIcon);

        

        /*

         * 获得系统托盘并为托盘添加一定的响应时间,如下所示：

         * 1.如果窗口存在，则在点击托盘图标的时候窗口会自动隐藏

         * 2.如果窗口不存在（即隐藏），则点击托盘图标时窗口会自动显示

         * 3.右键菜单Show: 显示窗口

         * 4.右键菜单Exit: 退出程序
