运行结果：

• 式样

         Menu式样
         SWT.BAR   ： 菜单栏，用于主菜单。
         SWT.DROP_DOWN   ： 下拉菜单用于子菜单。
         SWT.POP_UP   ：   鼠标右键弹出式菜单。

         MenuItem式样
         SWT.CASCADE   ： 有子菜单的菜单项。
         SWT.CHECK   ： 选中后前面带小钩。
         SWT.PUSH   ：   普通型菜单项。
         SWT.RADIO   ：   选中后前面带一小点。
         SWT.SEPERATOR   ： ---- 分隔符.
