使用 (Ctrl + Tab) 组合键向后导航
我（仍在）正在为应用程序实现按键导航。我已经成功地完成了我打算做的所有事情，只是还有一个更棘手的问题。
选项卡导航有效（循环浏览我标记为 TabStop 的项目）。我现在想要的是有一个功能，当我按下（Ctrl + Tab）时，可以向后循环浏览这些元素。虽然我知道如何捕获事件等，但我不知道是否有直接的方法告诉他（代码）例如 doBackwardsTab() ；或者我必须手动实现它？ （获取当前聚焦元素的父级，然后聚焦前一个子级）。
PS：如果有一个 doBackwardsTab() 东西我会很喜欢;)
I am (still) in the process of implementing key navigation for an app. I have managed to do just about everything I have set out to do I only have one more tricky issue.
Tab navigation works (cycles through the items I have marked as TabStop). What I want now is to have a functionality that cycles backwards through those elements when I press (Ctrl + Tab). While I know how to catch the event and so forth I don't know if there is a direct way of telling him (the code) to doBackwardsTab() for example; or do I have to implement it by hand? (Get the parent of the currently focused element and then focus the previous child).
P.S: I would love it if there were a doBackwardsTab() thingy ;)

按键是 Shift+Tab，如果普通 Tab 有效，则 Shift+Tab 也会的。
这是所有应用程序用来在控件中向后循环焦点的按键。您在评论中请求希望它使用 Ctrl+Tab 代替。这将破坏您的应用程序的可用性。不要这样做。尤其是当不进行编码的选项为您提供正确的解决方案时！
The key press is Shift+Tab and if plain Tab works then Shift+Tab will too.
This is the keypress that all apps use to cycle the focus backwards through your controls. You request in a comment that you want it to use Ctrl+Tab instead. This will destroy the usability of your app. Don't do it. Especially not when the option of doing no coding gives you the right solution!
