Siemens官方NXOPEN实例：MenuBarDotNetApp（带回调的菜单）

一、知识点提取

本实例通过注册带回调的菜单栏，实现了一个菜单多个操作对应一个项目dll，主要步骤如下：

1、注册开始菜单，应用模块入口

2、加载MenuBar菜单

3、回调方法实现

二、程序分析

1、源码所在目录

UGOPEN\SampleNXOpenApplications\.NET\MenuBarDotNetApp

2、主要功能分析

1、注册开始菜单，应用模块入口

VERSION 120 EDIT UG_GATEWAY_MAIN_MENUBAR MENU UG_APPLICATION ! ***NOTE button name must match the name you registered for! your application in the MenuBarManager()->RegisterApplication call  APPLICATION_BUTTON SAMPLE_CSHARP_APP LABEL Sample C Sharp Application LIBRARIES MenuBarCSharpApp MENU_FILES MenuBarCSharpApp.men END_OF_MENU 

这里通过LIBRARIES标签，指定了MenuBarCSharpApp这个生成文件

2、 加载MenuBar菜单

VERSION 120 EDIT UG_GATEWAY_MAIN_MENUBAR TOP_MENU CASCADE_BUTTON SAMPLE_CSHARP_APP_MENULABEL Sample C Sharp END_OF_TOP_MENU MENU SAMPLE_CSHARP_APP_MENU BUTTON SAMPLE_CSHARP_APP_BUTTON1LABEL Print Button IDACTIONS SAMPLE_CSHARP_APP__action1 BUTTON SAMPLE_CSHARP_APP_BUTTON2LABEL Test Callback ReturnsACTIONS SAMPLE_CSHARP_APP__action2 BUTTON SAMPLE_CSHARP_APP_BUTTON3LABEL Print Application IDACTIONS SAMPLE_CSHARP_APP__action3 BUTTON SAMPLE_CSHARP_APP_BUTTON4LABEL Print This Button DataACTIONS SAMPLE_CSHARP_APP__action4 TOGGLE_BUTTON SAMPLE_CSHARP_APP_BUTTON5LABEL Print Toggle StatusACTIONS SAMPLE_CSHARP_APP__action5 END_OF_MENU

这里ACTIONS指定的是方法，而不是dll文件

3、回调方法实现

    public static int Startup()    {        int retValue = 0;        try        {            if (theSession == null)            {                theSession = Session.GetSession();            }            if (lw == null)            {                lw = theSession.ListingWindow;            }            theUI.MenuBarManager.RegisterApplication("SAMPLE_CSHARP_APP",             new NXOpen.MenuBar.MenuBarManager.InitializeMenuApplication(Program.ApplicationInit),            new NXOpen.MenuBar.MenuBarManager.EnterMenuApplication(Program.ApplicationEnter),            new NXOpen.MenuBar.MenuBarManager.ExitMenuApplication(Program.ApplicationExit), true, true, true );            theUI.MenuBarManager.AddMenuAction("SAMPLE_CSHARP_APP__action1", new NXOpen.MenuBar.MenuBarManager.ActionCallback(Program.PrintButtonIdCB));            theUI.MenuBarManager.AddMenuAction("SAMPLE_CSHARP_APP__action2", new NXOpen.MenuBar.MenuBarManager.ActionCallback(Program.TestCallbackReturnsCB));            theUI.MenuBarManager.AddMenuAction("SAMPLE_CSHARP_APP__action3", new NXOpen.MenuBar.MenuBarManager.ActionCallback(Program.PrintApplicationIdCB));            theUI.MenuBarManager.AddMenuAction("SAMPLE_CSHARP_APP__action4", new NXOpen.MenuBar.MenuBarManager.ActionCallback(Program.PrintButtonDataCB));            theUI.MenuBarManager.AddMenuAction("SAMPLE_CSHARP_APP__action5", new NXOpen.MenuBar.MenuBarManager.ActionCallback(Program.PrintToggleStatusCB));        }        catch (NXOpen.NXException ex)        {            // ---- Enter your exception handling code here -----        }        return retValue;    }
