基于WAF框架：WPF Application Framework (WAF)

View层XAML中设置热键。

    <Window.InputBindings>

        <!--<KeyBinding Command="{Binding SaveCommand}" Key="S" Modifiers="Control"/>-->

        <KeyBinding Command="{Binding AboutCommand}" Key="F1"/>

    </Window.InputBindings>

ViewModel中定义该AboutCommand命令。

        private ICommand aboutCommand;

        public ICommand AboutCommand

        {

            get { return aboutCommand; }

            set { SetProperty(ref aboutCommand, value); }

        }

控制层写AboutCommand命令的实现。

namespace WafApplication1.Applications.Controllers

{

    [Export]

    internal class ApplicationController

    {

        private readonly ShellViewModel shellViewModel;

        private readonly DelegateCommand aboutCommand;

        [ImportingConstructor]

        public ApplicationController(ShellViewModel shellViewModel)

        {

            this.shellViewModel = shellViewModel;

            this.aboutCommand = new DelegateCommand(AboutCommand);

        }

        private void AboutCommand()

        {

            MessageBox.Show("F1 Command！");

        }

        public void Initialize()

        {

            shellViewModel.AboutCommand = this.aboutCommand;

        }

        public void Run()

        {

            shellViewModel.Show();

        }

        public void Shutdown()

        {

        }

    }

}

运行该项目，按F1即可看到弹出弹窗。

新的问题

给该Window窗体注册的快捷键，必须要在该窗体获得焦点时快捷键才有效。如果该窗体内有别的控件（如ListBox）获取了焦点，再点击该快捷键将不起效果。这时候，可考虑同样给该ListBox控件添加相同的快捷键命令。

<!-- 快捷键 -->

<ListBox.InputBindings>

    <KeyBinding Command="{Binding ShortcutScaleCommand}" Key="F1"/>

</ListBox.InputBindings>
