没有重点的键绑定 [英] Keybindings without any focus

问题描述

我有一个WPF屏幕，其中有六个按钮。我想将每个键绑定与关联。它们都是通过MVVM由ICommand驱动的。

I have a WPF screen that has half a dozen buttons. I'd like to associate each with a keybinding. They are all ICommand driven via MVVM.

我目前具有绑定到事件的绑定，而不是实际的按钮：

I currently have the keybindings bound to the events and not the actual buttons:

<UserControl.InputBindings>
        <KeyBinding Key="N"  Command="{Binding MyCommand}"/>

但是，要使任何键绑定正常工作，我必须至少设置1个按钮以将焦点放在后面的代码中。我真的不想这样做，因为每个按钮/命令是否激活都具有不同的规则，并且我希望焦点动画在页面加载时不处于激活状态。

However, for any Keybinding to work I have to set at least 1 button to focus in the codebehind. I'd really like to not do this because each button/command has different rules on if it's active or not and I have focus animation that I'd prefer wasn't active on page load.

这可能吗？还是我必须设置焦点？

Is this possible or do I have to set focus?

推荐答案

您只需要将usercontrol的focusable设置为true，因为某些元素默认情况下不为真

You just need to set usercontrol's focusable to true, because some element doesn't have it to true by default

<UserControl Focusable="True">

然后您必须在用户控件的加载事件中设置this.Focus（）

Then you have to set this.Focus() in the loaded event of the user control
