当鼠标悬停在AvalonEdit中的特定文本上时，如何触发事件?

问题描述

我有一个基于AvalonEdit WPF的应用程序.

I have an AvalonEdit WPF based application.

当用户将鼠标悬停在编辑器中的特定文本上时，我想定义一种特定的行为，类似于使用python tkinter的tag_binding.

I want to define a specific behaviour when the user hovers with the mouse over a specific text in the editor, similar to tag_binding with python tkinter.

我在Google周围搜索，找不到任何方法.

I googled around, and couldn't find any way to do this.

这怎么办?

要点似乎是在此时(2010年！)，尚无直接方法可以做到，但是给出了以下提示.

The gist seems to be that at this time (2010!) there where no direct way to do it, but the following hint was given.

示例代码:

    ToolTip toolTip = new ToolTip();

    void TextEditorMouseHover(object sender, MouseEventArgs e)
    {
        var pos = textEditor.GetPositionFromPoint(e.GetPosition(textEditor));
        if (pos != null) {
            toolTip.PlacementTarget = this; // required for property inheritance
            toolTip.Content = pos.ToString();
            toolTip.IsOpen = true;
            e.Handled = true;
        }
    }

    void TextEditorMouseHoverStopped(object sender, MouseEventArgs e)
    {
        toolTip.IsOpen = false;
    }
