我知道如何处理关键事件,即
- private void Page_KeyUp(object sender,KeyRoutedEventArgs e)
- {
- switch (e.Key)
- {
- case Windows.System.VirtualKey.Enter:
- // handler for enter key
- break;
- case Windows.System.VirtualKey.A:
- // handler for A key
- break;
- default:
- break;
- }
- }
但是如果我需要在小写’a’和大写’A’之间辨别怎么办？另外,如果我想处理百分号’％’之类的键,该怎么办？
其他地方有答案.对于那些感兴趣的人……
- public Foo()
- {
- this.InitializeComponent();
- Window.Current.CoreWindow.CharacterReceived += KeyPress;
- }
- void KeyPress(CoreWindow sender,CharacterReceivedEventArgs args)
- {
- args.Handled = true;
- Debug.WriteLine("KeyPress " + Convert.tochar(args.KeyCode));
- return;
- }
更好的是,移动Window.Current.CoreWindow.CharacterReceived = KeyPress;进入GotFocus事件处理程序,并添加Window.Current.CoreWindow.CharacterReceived – = KeyPress;进入LostFocus事件处理程序.
