如何在WPF中使用键盘快捷键? [英] How do I work with keyboard shortcuts in WPF?
问题描述
我有10个复选框项目，按字母顺序排列，例如:
I have 10 check box items sorted alphabetically, say for example:
Apple，AirCraft，Ball，Bottom，Cat等
通过按 A 键，必须将焦点设置为 Apple 复选框，将 B -设置为 Ball >.我怎样才能做到这一点?这些复选框项目由于项目来源计数而动态可变.
By pressing the A key the focus must be set to the Apple check box, B - to Ball. How can I do this? These check box items are dynamically variable due to the item source count.
我想，因为复选框项目未在XAML中进行硬编码，所以我无法标记；我在运行时加载它们.如果我有类似以下的内容怎么办?
Since checkbox items are not hardcoded in XAML I cannot tag, I guess; I load them during run time. And what if I have items like the following?
- 苹果
- Apple1
- Apple2
- Apple
- Apple1
- Apple2
在这种情况下，我无法设置快捷方式的正确性，因此，如果我按 A ，则第一个以字母 A 开头的项目将获得焦点，然后再次按 A ，将焦点设置为以字母 A 开头的下一项.如果到达最后一个以字母 A 开头的项目，那么再次按 A 则必须转到第一个以字母 A 开头的项目>，所以这是我的要求:).我该怎么办?
In this scenario I can't set the shortcut right, so instead, if I press A the first item that starts with letter A will get focus and again pressing A, focus set to the next item that starts with letter A. If it reaches the last item that starts with letter A then again if I press A it has to go to the first item that has starting letter A, so this is my requirement:). How can I do this?
推荐答案
您可以使用键盘导航，方法是先按alt键，然后将复选框的内容设置为:
You can use the keyboard navigation by first pressing the alt key, and setting the check boxes content as:
<CheckBox Content="_Apple" />
<CheckBox Content="_Ball" />
请记住，相关的键盘快捷键将是"_"符号后的快捷键.
Keep in mind that the associated keyboard shortcut will be the one after the "_" symbol.
