UWP 响应键盘组合快捷键

方法1：响应Ctrl+？快捷键

首先在load事件或者keydown事件内注册事件

        public MainPage(){this.InitializeComponent();// Register for accelerator key events used for button hotkeysWindow.Current.CoreWindow.Dispatcher.AcceleratorKeyActivated += Dispatcher_AcceleratorKeyActivated;}

 

注册的事件如下（检测Ctrl+V和Ctrl+N）：

private void Dispatcher_AcceleratorKeyActivated(CoreDispatcher sender, AcceleratorKeyEventArgs args)
{if (args.EventType.ToString().Contains("Down")){var ctrl = Window.Current.CoreWindow.GetKeyState(VirtualKey.Control);if (ctrl.HasFlag(CoreVirtualKeyStates.Down)){switch (args.VirtualKey){case VirtualKey.V:ViewOrders_Tapped(this, null);break;case VirtualKey.N:NewOrder_Tapped(this, null);break;}}}
}

 

 

 

方法2：响应Ctrl+鼠标滚轮

private void WheelChanged(object sender, PointerRoutedEventArgs e)
{RichEditBox editor = sender as RichEditBox;var x = e.GetCurrentPoint(editor).Properties.MouseWheelDelta;var ctrl = Window.Current.CoreWindow.GetKeyState(VirtualKey.Control);if (ctrl.HasFlag(CoreVirtualKeyStates.Down)){if (x > 0){redit.Document.Selection.CharacterFormat.Size += 1;}else{redit.Document.Selection.CharacterFormat.Size -= 1;}e.Handled = true;//取消内容滚动
    }
}

说明：所有UI元素都具有PointerWheelChanged事件，响应此事件同时判断Ctrl状态判断用户操作。例子中响应的UIElement元素为RichEditBox，根据实际情况更改。
