始终以基本形式处理 PreviewKeyDown 事件 [英] Always handle the PreviewKeyDown event in a base form

问题描述

我们需要在基本表单中处理这个事件，而不管当前有哪些控件具有焦点.我们有几个全局键命令，无论控制焦点如何，它们都需要工作.

We need to handle this event in the base form, regardless of which controls currently have focus. We have a couple of global key commands that need to work regardless of control focus.

这是通过正常处理表单中的 PreviewKeyDown 事件来实现的.当我们向表单添加用户控件时，该事件不再触发.

This works by handling the PreviewKeyDown event in the form normally. When we add a user control to the form, the event no longer fires.

我在这里遗漏了一些微不足道的东西吗?还是需要先处理用户控件中的事件?

Am I missing something trivial here? Or do we need to handle the event in the user control first?

感谢您的帮助！

推荐答案

我们最终做到了:

我通过以下设置找到了一个隐藏菜单项的解决方法:

I found a workaround for this by setting up a hidden menu item by setting:

ToolStripMenuItem.Visible = false

(感谢这篇文章).

似乎总是在表单的主菜单中搜索您的快捷键组合.无论哪个控件具有焦点，这都有效

It appears that the Main Menu of a form always gets searched for your shortcut key combination. This works regardless of whick control has focus
