我是WPF和Mvvm的新手,尝试用加速键来理解菜单。我有以下xaml。帮助和子菜单H1,H2按预期工作,即按Alt + H然后按2,处理程序MenuItem_Click_2被调用。这很好,但我想用Mvvm做这个。如果你看到_View菜单(这里是Mvvm),只有Alt + V可以工作,这显示了与ViewModel绑定的菜单如下。但进一步说,如果我键入Alt + V然后键入G或P,它就不起作用。我想我错过了一些非常基本的东西。它是什么?
_Help完全可以正常工作如下

Controls
支持KeyBinding
。例如,ItemsControl
可以有各种KeyBinding's
:
<ItemsControl ItemsSource="{Binding FooData}">
<ItemsControl.InputBindings>
<KeyBinding Modifiers="Alt" Key="V" Command="{Binding YourCommand}"/>
</ItemsControl.InputBindings>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
您还可以设置多个修饰符:
<KeyBinding Modifiers="Alt+Shift" Key="V" Command="{Binding YourCommand}"/>
