WPF Menu实现快捷键操作

很多小伙伴说，在Menu中，实现单个快捷键操作很简单，怎么实现多个快捷键操作和，组合快捷键呢，今天他来了。

上代码和效果图

一、Ctrl + Shift + 任意子母键实现快捷键组合

<Window x:Class="XH.TemplateLesson.MenuWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:local="clr-namespace:XH.TemplateLesson"mc:Ignorable="d"Title="MenuWindow" Height="450" Width="800"><Window.InputBindings><!-- 定义组合快捷键 Ctrl+Shift+S --><!--先要什么组合修改key 或者 Modifiers 即可注意：这里只可以改为Ctrl Alt Shift Windows + 任意字母键的快捷方式--><KeyBinding Key="S" Modifiers="Control+Shift" Command="{Binding NewCommand}" /></Window.InputBindings><Grid><Menu><MenuItem Header="新建(_F)"><MenuItem Header="新建" /><MenuItem Header="全部保存" Command="{Binding NewCommand}" InputGestureText="Ctrl+Shift+S"  /></MenuItem><MenuItem Header="编辑(_E)"/></Menu></Grid>
</Window>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;namespace XH.TemplateLesson
{/// <summary>/// MenuWindow.xaml 的交互逻辑/// </summary>public partial class MenuWindow : Window{public ICommand NewCommand { get; set; }public MenuWindow(){InitializeComponent();DataContext = this;NewCommand = new RelayCommand(ExecuteNew);}private void ExecuteNew(object parameter){MessageBox.Show("New Command Executed");}public class RelayCommand : ICommand{private readonly Action<object> _execute;private readonly Func<object, bool> _canExecute;public RelayCommand(Action<object> execute, Func<object, bool> canExecute = null){_execute = execute;_canExecute = canExecute;}public bool CanExecute(object parameter){return _canExecute == null || _canExecute(parameter);}public void Execute(object parameter){_execute(parameter);}public event EventHandler CanExecuteChanged{add { CommandManager.RequerySuggested += value; }remove { CommandManager.RequerySuggested -= value; }}}}
}

直接Ctrl + Shift + S弹出：

二、实现Ctrl + 多个字母键组合

<Window x:Class="XH.TemplateLesson.MenuWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:local="clr-namespace:XH.TemplateLesson"mc:Ignorable="d" <!--绑定键盘事件-->PreviewKeyDown="Window_PreviewKeyDown"PreviewKeyUp="Window_PreviewKeyUp"Title="MenuWindow" Height="450" Width="800"><Grid><Menu><MenuItem Header="新建(_F)"><MenuItem Header="新建" /><MenuItem Header="整理代码格式" InputGestureText="Ctrl+K+D"  /></MenuItem></Menu></Grid>
</Window>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;namespace XH.TemplateLesson
{/// <summary>/// MenuWindow.xaml 的交互逻辑/// </summary>public partial class MenuWindow : Window{private bool _isCtrlPressed;private bool _isAPressed;public MenuWindow(){InitializeComponent();}// 下方的K 和D 根据自己写的代码来进行修改private void Window_PreviewKeyDown(object sender, KeyEventArgs e){// 先 Cttrlif (e.Key == Key.LeftCtrl || e.Key == Key.RightCtrl){_isCtrlPressed = true;}// 再 Ctrl + K else if (e.Key == Key.K && _isCtrlPressed){_isAPressed = true;}// 最后 Cttrl + K + Delse if (e.Key == Key.D && _isCtrlPressed && _isAPressed){ExecuteCustomCommand();}}// 键盘释放 如果释放 无效private void Window_PreviewKeyUp(object sender, KeyEventArgs e){if (e.Key == Key.LeftCtrl || e.Key == Key.RightCtrl){_isCtrlPressed = false;}else if (e.Key == Key.K){_isAPressed = false;}}private void ExecuteCustomCommand(){MessageBox.Show("快捷键调用成功: Ctrl + K + D");}}
}

按下Ctrl + K + D:

单键 Alt + 字母弹出

<Menu><!--直接下划线 + 字母 就可以alt + 字母弹出--><MenuItem Header="新建(_F)"><MenuItem Header="新建" /><MenuItem Header="整理代码格式" InputGestureText="Ctrl+K+D"  /></MenuItem>
</Menu>
