我正在开发一个MS Word 2010的插件,希望在右键菜单中添加一些菜单项(仅当选择了一些文本时)。我看到了一些添加菜单项的例子,但找不到如何有条件地添加菜单项。 简而言之,我想覆盖类似OnRightClick处理程序的东西。 提前感谢。
WindowBeforeRightClick
事件。在事件内部,定位所需的命令栏和特定控件,并处理Visible
或Enabled
属性。Visible
属性。 //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;
}
