MS Word加载项:RIght点击处理程序

Question

我正在为MS Word 2010开发一个加载项,我想在右键菜单中添加几个菜单项(仅当选择了一些文本时).我看过几个例子来添加项目,但无法找到如何有条件地添加项目.简而言之,我想覆盖像OnRightClick处理程序之类的东西.提前致谢.

这很简单,你需要处理这个WindowBeforeRightClick事件.在事件内部找到所需的命令栏和specfic控件并处理Visible或Enabled属性.

在下面的示例中,我根据选择切换在Visible文本命令栏上创建的自定义按钮的属性(如果选择包含"C#",则隐藏按钮,否则显示它)

    //using Word = Microsoft.Office.Interop.Word;
    //using Office = Microsoft.Office.Core;

    Word.Application application;

    private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {
        application = this.Application;
        application.WindowBeforeRightClick +=
            new Word.ApplicationEvents4_WindowBeforeRightClickEventHandler(application_WindowBeforeRightClick);

        application.CustomizationContext = application.ActiveDocument;

        Office.CommandBar commandBar = application.CommandBars["Text"];
        Office.CommandBarButton button = (Office.CommandBarButton)commandBar.Controls.Add(
            Office.MsoControlType.msoControlButton);
        button.accName = "My Custom Button";
        button.Caption = "My Custom Button";
    }

    public void application_WindowBeforeRightClick(Word.Selection selection, ref bool Cancel)
    {
        if (selection != null && !String.IsNullOrEmpty(selection.Text))
        {
            string selectionText = selection.Text;

            if (selectionText.Contains("C#"))
                SetCommandVisibility("My Custom Button", false);
            else
                SetCommandVisibility("My Custom Button", true);
        }
    }

    private void SetCommandVisibility(string name, bool visible)
    {
        application.CustomizationContext = application.ActiveDocument;
        Office.CommandBar commandBar = application.CommandBars["Text"];
        commandBar.Controls[name].Visible = visible;
    }
