如何在MDI程序中把子窗体菜单合并到主窗体上

       这里只讲在MDI中，子菜单与父菜单合并的简单方法。

 

首先在MDI的主窗体中：

1．  在主窗体构造函数中，添加如下代码，注意要在InitializeComponent调用之后，如：

            //Add File Menu

            MenuItem miFile = mnuMain.MenuItems.Add("&File");

            miFile.MergeOrder=1;

            miFile.MergeType = MenuMerge.MergeItems;

 

            MenuItem miAddDoc = new MenuItem( "&Add Document",

                new EventHandler(this.FileAdd_Clicked),

                Shortcut.CtrlA );

            miAddDoc.MergeOrder=100;

 

            MenuItem miExit = new MenuItem( "E&xit",

                new EventHandler(this.FileExit_Clicked),

                Shortcut.CtrlX );

            miExit.MergeOrder=110;

 

            miFile.MenuItems.Add(miAddDoc);

            miFile.MenuItems.Add("-");     // Give a seperator

            miFile.MenuItems.Add(miExit);

 

            //Add Window Menu

            MenuItem miWindow = mnuMain.MenuItems.Add("&Window");

            miWindow.MergeOrder = 10;

            miWindow.MenuItems.Add( "&Cascade",

                new EventHandler(this.WindowCascade_Clicked));

            miWindow.MenuItems.Add( "Tile &Horizontal",

                new EventHandler(this.WindowTileH_Clicked));

            miWindow.MenuItems.Add( "Tile &Vertical",

                new EventHandler(this.WindowTileV_Clicked));

            miWindow.MdiList = true ; //Adds the MDI Window List to the bottom of the menu

 

2．  然后为相应的Menu_Click事件定义函数，如：

        #region MENU_CLICK_MESSAGE_HANDLE

        //File->Add Menu item handler

        protected void FileAdd_Clicked(object sender, System.EventArgs e)

        {

            AddMDIChild() ; //Create new MDI child window

        }

 

        //File->Exit Menu item handler

        protected void FileExit_Clicked(object sender, System.EventArgs e)

        {

            this.Close();

        }

 

        //Window->Cascade Menu item handler

        protected void WindowCascade_Clicked(object sender, System.EventArgs e)

        {

            this.LayoutMdi(MdiLayout.Cascade);

        }

 

        //Window->Tile Horizontally Menu item handler

        protected void WindowTileH_Clicked(object sender, System.EventArgs e)
