c# - 如何在 Microsoft Office Word 中添加菜单项

Question

我尝试根据 this 在 Microsoft Word 中创建右键单击菜单项发布。

这是我的代码:

    private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {
        try
        {
            eventHandler = new _CommandBarButtonEvents_ClickEventHandler(MyButton_Click);
            Word.Application applicationObject = Globals.ThisAddIn.Application as Word.Application;
            applicationObject.WindowBeforeRightClick += new Microsoft.Office.Interop.Word.ApplicationEvents4_WindowBeforeRightClickEventHandler(App_WindowBeforeRightClick);
        }
        catch (Exception exception)
        {
            MessageBox.Show("Error: " + exception.Message);
        }
    }

    void App_WindowBeforeRightClick(Microsoft.Office.Interop.Word.Selection Sel, ref bool Cancel)
    {
        try
        {
            this.AddItem();
        }
        catch (Exception exception)
        {
            MessageBox.Show("Error: " + exception.Message);
        }

    }
    private void AddItem()
    {
        Word.Application applicationObject = Globals.ThisAddIn.Application as Word.Application;
        CommandBarButton commandBarButton = applicationObject.CommandBars.FindControl(MsoControlType.msoControlButton, missing, "HELLO_TAG", missing) as CommandBarButton;
        if (commandBarButton != null)
        {
            System.Diagnostics.Debug.WriteLine("Found button, attaching handler");
            commandBarButton.Click += eventHandler;
            return;
        }
        CommandBar popupCommandBar = applicationObject.CommandBars["Text"];
        bool isFound = false;
        foreach (object _object in popupCommandBar.Controls)
        {
            CommandBarButton _commandBarButton = _object as CommandBarButton;
            if (_commandBarButton == null) continue;
            if (_commandBarButton.Tag.Equals("HELLO_TAG"))
            {
                isFound = true;
                System.Diagnostics.Debug.WriteLine("Found existing button. Will attach a handler.");
                commandBarButton.Click += eventHandler;
                break;
            }
        }
        if (!isFound)
        {
            commandBarButton = (CommandBarButton)popupCommandBar.Controls.Add(MsoControlType.msoControlButton, missing, missing, missing, true);
            System.Diagnostics.Debug.WriteLine("Created new button, adding handler");
            commandBarButton.Click += eventHandler;
            commandBarButton.Caption = "h5";
            commandBarButton.FaceId = 356;
            commandBarButton.Tag = "HELLO_TAG";
            commandBarButton.BeginGroup = true;
        }
    }

    private void RemoveItem()
    {
        Word.Application applicationObject = Globals.ThisAddIn.Application as Word.Application;
        CommandBar popupCommandBar = applicationObject.CommandBars["Text"];
        foreach (object _object in popupCommandBar.Controls)
        {
            CommandBarButton commandBarButton = _object as CommandBarButton;
            if (commandBarButton == null) continue;
            if (commandBarButton.Tag.Equals("HELLO_TAG"))
            {
                popupCommandBar.Reset();
            }
        }
    }
    private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
    {
        Word.Application App = Globals.ThisAddIn.Application as Word.Application;
        App.WindowBeforeRightClick -= new Microsoft.Office.Interop.Word.ApplicationEvents4_WindowBeforeRightClickEventHandler(App_WindowBeforeRightClick);

    }

    #region VSTO generated code

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InternalStartup()
    {
        this.Startup += new System.EventHandler(ThisAddIn_Startup);
        this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
    }
    #endregion
    //Event Handler for the button click

    private void MyButton_Click(CommandBarButton cmdBarbutton, ref bool cancel)
    {
        System.Windows.Forms.MessageBox.Show("Hello !!! Happy Programming", "l19 !!!");
        RemoveItem();
    }
}

当我右键点击一个字母时的结果:

但是对于一张 table 我做不到。查看屏幕截图以了解我的意思:

当我右键单击 ms word 的表格时，我无法添加项目菜单。请帮我。谢谢!!

对不起我的英语，...

Word 维护不止一个上下文菜单。你可以通过枚举Application.CommandBars中的所有CommandBar对象来查看它们，它们的位置是msoBarPopup:

foreach (var commandBar in applicationObject.CommandBars.OfType<CommandBar>()
                               .Where(cb => cb.Position == MsoBarPosition.msoBarPopup))
{
    Debug.WriteLine(commandBar.Name);
}

链接示例中使用的命令栏名为“文本”，该命令栏与右键单击段落文本某处时弹出的上下文菜单相关。

但是，要向表格的上下文菜单中添加内容，您必须将按钮添加到适当的与表格相关的上下文菜单中。表格具有不同的上下文菜单，具体取决于您单击时选择的内容:

• applicationObject.CommandBars["表格"]
• applicationObject.CommandBars["表格文本"]
• applicationObject.CommandBars["表格单元格"]
• applicationObject.CommandBars["表格标题"]
• applicationObject.CommandBars["表列表"]
• applicationObject.CommandBars["表格图片"]

所以我建议您提取一个方法，将按钮添加到 CommandBar，然后使用要添加按钮的所有命令栏调用该方法。类似于以下内容:

private void AddButton(CommandBar popupCommandBar)
{
    bool isFound = false;
    foreach (var commandBarButton in popupCommandBar.Controls.OfType<CommandBarButton>())
    {
        if (commandBarButton.Tag.Equals("HELLO_TAG"))
        {
            isFound = true;
            Debug.WriteLine("Found existing button. Will attach a handler.");
            commandBarButton.Click += eventHandler;
            break;
        }
    }
    if (!isFound)
    {
        var commandBarButton = (CommandBarButton)popupCommandBar.Controls.Add
            (MsoControlType.msoControlButton, missing, missing, missing, true);
        Debug.WriteLine("Created new button, adding handler");
        commandBarButton.Click += eventHandler;
        commandBarButton.Caption = "Hello !!!";
        commandBarButton.FaceId = 356;
        commandBarButton.Tag = "HELLO_TAG";
        commandBarButton.BeginGroup = true;
    }
}

// add the button to the context menus that you need to support
AddButton(applicationObject.CommandBars["Text"]);
AddButton(applicationObject.CommandBars["Table Text"]);
AddButton(applicationObject.CommandBars["Table Cells"]);
