对于没有进入等于在System.Windows.Input.Key枚举密钥？ [英] No entry for the Equals key in the System.Windows.Input.Key enum?

问题描述

我想设置一个 InputGesture 在 RoutedUICommand ，挂钩起来赶上当用户presses 按Ctrl + = 。我使用的是 KeyGesture 的对象，但我不能看到 System.Windows.Input.Key 枚举了等号（=）键。

I'm trying to set an InputGesture on a RoutedUICommand, hooking it up to catch when the user presses Ctrl + =. I'm using a KeyGesture object, but I can't see an entry in the System.Windows.Input.Key enum for the equals ('=') key.

我的期待是能够做到以下几点：

What I was expecting was to be able to do the following:

ZoomIn = new RoutedUICommand("Zoom In", "ZoomIn", typeof(Window),
    new InputGestureCollection { 
        new KeyGesture(Key.Equals, ModifierKeys.Control) 
    });

任何人都可以点我朝着正确的方向吗？

Can anyone point me in the right direction, please?

推荐答案

正如刚才ChrisF，我需要搞我的大脑一点点。对于它的价值，价值在处理的KeyDown 事件是 Key.OemPlus 。

As pointed out by ChrisF, I needed to engage my brain a little. For what it's worth, the value generated when handling the KeyDown event is Key.OemPlus.

更新：
这样做的一个后果是，如果你正在做的一样一样的我，你要在菜单中的命令，你可能会想使用重载的构造函数 KeyGesture 这需要 displayString 。例如：

Update:
One consequence of this is that, if you're doing the same same as me and you're going to use the command in a menu, you'll probably want to use the overloaded constructor for KeyGesture that takes a 3rd parameter of displayString. For example:

new KeyGesture(Key.Equals, ModifierKeys.Control, "Ctrl+=")

否则，你会看到显示为快捷键（在我的情况），CTRL + OemPlus，这是不完全不可取的。诚然，以上还不是很大，但它比OemPlus更好。

Otherwise, you'll see the keyboard shortcut displayed as (in my case) "Ctrl+OemPlus", which isn't exactly desirable. Admittedly, the above still isn't great, but it's better than "OemPlus".
