RichTextBox:切换HideSelection或WordWrap清除撤消吗? [英] RichTextBox: Toggling HideSelection or WordWrap Clears Undo?

问题描述

使用WinXP和Visual Studio 2008 ...
当我更改RichTextBox中的HideSelection或WordWrap属性时，撤消缓冲区被清除(CanUndo变为False).我不确定这是正常现象还是我自己系统中的错误，因为当我打开或关闭WordWrap时，MS Notepad和Fookes NoteTab也会表现出这种现象.

要么我一直都没有注意，要么XP已经开发了一个bug.

Using WinXP and Visual Studio 2008...
When I change the HideSelection or WordWrap properties in a RichTextBox, the Undo buffer is cleared (CanUndo becomes False). I was unsure if this was normal behavior or a bug in my own system, since MS Notepad and Fookes NoteTab also exhibit this behavior when I toggle WordWrap on or off.

Either I''ve not been paying attention all this time, or XP has developed a bug.

推荐答案

我对其进行了测试，请在我的旧Windows应用程序中进行观察，但在WordWrap更改后保留撤消的WPF上不适用.我在XP上测试过.因此，很难说出问题出在哪里，但这是一种错误:撤消不应该只依赖于与视图相关的属性.

I tested it, observe it on my old native-windows application, but not on WPF where the undo is preserved after changing of WordWrap. I tested it on XP. So, hard to say where the problem is, but this is a kind of bug: Undo should not depends on properties related only to view.
