添加菜单项默认的上下文菜单 [英] add menu item to default context menu

问题描述

我想一个菜单项添加到一个RichTextBox的默认文本菜单。我可以创建一个新的上下文菜单，但后来我失去了显示在默认菜单的拼写检查的建议。有没有一种方法来添加一个项目而无需重新实现一切吗？

I'd like to add a menu item to the default ContextMenu of a RichTextBox. I can create a new context menu but then I loose the spell check suggestions that show up in the default menu. Is there a way to add an item without re-implementing everything?

推荐答案

这不是太靠谱重新实现与拼写建议，剪切，粘贴，RichTextBox的上下文菜单等。

It's not too tricky to reimplement the RichTextBox context menu with spelling suggestions, Cut, Paste, etc.

挂钩的上下文菜单中开幕活动如下：

Hook up the context menu opening event as follows:

AddHandler(RichTextBox.ContextMenuOpeningEvent, new ContextMenuEventHandler(RichTextBox_ContextMenuOpening), true);

在事件处理程序构建上下文菜单中，你所需要的。您可以创建具有以下现有的上下文菜单中的菜单项：

Within the event handler build the context menu as you need. You can recreate the existing context menu menu items with the following:

private IList<MenuItem> GetSpellingSuggestions()
{
    List<MenuItem> spellingSuggestions = new List();
    SpellingError spellingError = myRichTextBox.GetSpellingError(myRichTextBox.CaretPosition);
    if (spellingError != null)
    {
    	foreach (string str in spellingError.Suggestions)
    	{
    		MenuItem mi = new MenuItem();
    		mi.Header = str;
    		mi.FontWeight = FontWeights.Bold;
    		mi.Command = EditingCommands.CorrectSpellingError;
    		mi.CommandParameter = str;
    		mi.CommandTarget = myRichTextBox;
    		spellingSuggestions.Add(mi);
    	}
    }
    return spellingSuggestions;
}

private IList<MenuItem> GetStandardCommands()
{
    List<MenuItem> standardCommands = new List();

    MenuItem item = new MenuItem();
    item.Command = ApplicationCommands.Cut;
    standardCommands.Add(item);

    item = new MenuItem();
    item.Command = ApplicationCommands.Copy;
    standardCommands.Add(item);

    item = new MenuItem();
    item.Command = ApplicationCommands.Paste;
    standardCommands.Add(item);

    return standardCommands;
}

如果有拼写错误，你可以创造全部忽略与：

If there are spelling errors, you can create Ignore All with:

MenuItem ignoreAllMI = new MenuItem();
ignoreAllMI.Header = "Ignore All";
ignoreAllMI.Command = EditingCommands.IgnoreSpellingError;
ignoreAllMI.CommandTarget = textBox;
newContextMenu.Items.Add(ignoreAllMI);

添加分隔符的要求。添加这些新的上下文菜单中的项，然后添加你闪亮的新的MenuItems。

Add separators as required. Add those to the new context menu's items, and then add your shiny new MenuItems.

我要不停地寻找一种方式来获得实际的上下文菜单，虽然，因为这是有关的东西，我会努力在不久的将来。

I'm going to keep looking for a way to obtain the actual context menu though, as this is relevant to something I'll be working on in the near future.
