RCP系统的菜单功能的使用

              在项目RCP 应用程序中添加系统菜单的在ApplicationActionBarAdvisor 中创建相关的Action，并注册之后使用。

RCP系统提供的reflesh,save的功能均在ActionFactory类中使用时调用。如果想重新启动：
采用以下代码：

 PlatformUI.getWorkbench().restart(); 

看下面的源代码如下：

    // in the fill methods.  This ensures that the actions aren't recreated

    private IWorkbenchAction aboutAction;

        toolbar.add(openViewAction);
        toolbar.add(messagePopupAction);
    }
