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 hotkeys Window.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。
