提问by keerthee
I am trying to add a keyboard shortcut to the menu item in my xaml code using
我正在尝试使用以下命令向我的 xaml 代码中的菜单项添加键盘快捷键
<MenuItem x:Name="Options" Header="_Options" InputGestureText="Ctrl+O" Click="Options_Click"/>
with Ctrl+O
与Ctrl+O
But it is not working - it is not calling the Click option.
但它不起作用 - 它没有调用 Click 选项。
Are there any solutions for this?
有什么解决方案吗？

InputGestureTextis just a text. It does not bind key to MenuItem.
InputGestureText只是一个文本。它不会将 key 绑定到MenuItem.
This property does not associate the input gesture with the menu item; it simply adds text to the menu item. The application must handle the user's input to carry out the action
此属性不会将输入手势与菜单项相关联；它只是向菜单项添加文本。应用程序必须处理用户的输入以执行操作
What you can do is create RoutedUICommandin your window with assigned input gesture
您可以做的是RoutedUICommand使用指定的输入手势在您的窗口中创建
public partial class MainWindow : Window
{
public static readonly RoutedCommand OptionsCommand = new RoutedUICommand("Options", "OptionsCommand", typeof(MainWindow), new InputGestureCollection(new InputGesture[]
{
new KeyGesture(Key.O, ModifierKeys.Control)
}));
//...
}
and then in XAML bind that command to some method set that command against MenuItem. In this case both InputGestureTextand Headerwill be pulled from RoutedUICommandso you don't need to set that against MenuItem
然后在 XAML 中将该命令绑定到某个方法，将该命令设置为针对MenuItem. 在这种情况下，InputGestureText和Header都将从中拉出，RoutedUICommand因此您无需将其设置为MenuItem
<Window.CommandBindings>
<CommandBinding Command="{x:Static local:MainWindow.OptionsCommand}" Executed="Options_Click"/>
</Window.CommandBindings>
<Menu>
<!-- -->
<MenuItem Command="{x:Static local:MainWindow.OptionsCommand}"/>
</Menu>

you should succeed in this way: Defining MenuItem ShortcutsBy using KeyBindings:
您应该以这种方式成功： 使用 KeyBindings定义 MenuItem 快捷方式：
<Window.CommandBindings> <CommandBinding Command="New" Executed="CommandBinding_Executed" /> </Window.CommandBindings> <Window.InputBindings> <KeyBinding Key="N" Modifiers="Control" Command="New"/> </Window.InputBindings>
