定义MenuItem快捷方式 [英] Defining MenuItem Shortcuts

问题描述

我需要一种简单的方法来设置菜单项的快捷方式.

I need a simple way to set a shortcut for menu items.

但这不适用于快捷方式，只能单击:

But this don´t work with shortcut, just with click:

<MenuItem Header="Editar">
    <MenuItem Header="Procurar" Name="MenuProcurar"
              InputGestureText="Ctrl+F"
              Click="MenuProcurar_Click">
        <MenuItem.ToolTip>
            <ToolTip>
                Procurar
            </ToolTip>
        </MenuItem.ToolTip>
    </MenuItem>
</MenuItem>

我正在使用WPF 4.0

推荐答案

您需要使用 CommandBindings (如果您(重新)使用 RoutedCommands ，例如在 ApplicationCommands类)中的快捷方式应该起作用的控件.

You need to use KeyBindings (and CommandBindings if you (re)use RoutedCommands such as those found in the ApplicationCommands class) for that in the controls where the shortcuts should work.

例如

<Window.CommandBindings>
        <CommandBinding Command="New" Executed="CommandBinding_Executed" />
</Window.CommandBindings>
<Window.InputBindings>
        <KeyBinding Key="N" Modifiers="Control" Command="New"/>
</Window.InputBindings>

对于自定义RoutedCommands:

static class CustomCommands
{
    public static RoutedCommand DoStuff = new RoutedCommand();
}

用法:

<Window
    ...
    xmlns:local="clr-namespace:MyNamespace">
        <Window.CommandBindings>
                <CommandBinding Command="local:CustomCommands.DoStuff" Executed="DoStuff_Executed" />
        </Window.CommandBindings>
        <Window.InputBindings>
                <KeyBinding Key="D" Modifiers="Control" Command="local:CustomCommands.DoStuff"/>
        </Window.InputBindings>
    ...
</Window>

(实现 ICommand接口而不是使用RoutedCommands.您可以有一个构造函数，该构造函数使用Execute和CanExecute的委托来轻松创建执行不同功能的命令，此类实现通常称为DelegateCommand或.这样，您就不需要CommandBindings.)

(It is often more convenient to implement the ICommand interface rather than using RoutedCommands. You can have a constructor which takes delegates for Execute and CanExecute to easily create commands which do different things, such implementations are often called DelegateCommand or RelayCommand. This way you do not need CommandBindings.)
