UWP 響應鍵盤組合快捷鍵

方法1：響應Ctrl+？快捷鍵

首先在load事件或者keydown事件內注冊事件

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

?

注冊的事件如下（檢測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：響應Ctrl+鼠標滾輪

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;//取消內容滾動
    }
}

說明：所有UI元素都具有PointerWheelChanged事件，響應此事件同時判斷Ctrl狀態判斷用戶操作。例子中響應的UIElement元素為RichEditBox，根據實際情況更改。
