Silverlight处理多个按键组合 [英] Silverlight handling multiple key press combinations

问题描述

我有一个Silverlight应用程序，其中我捕获某些按键，如 Tab 或 Ctrl 来执行一些操作。但是，我想要同时处理多个按键，例如 Ctrl + R 或类似的东西。有没有办法在Silverlight中做到这一点，如果是的话，怎么样？

解决方案

看看 ModifierKeys枚举以检查多个按键组合。有关代码示例和更多信息，请参阅 Silverlight键盘支持

  void Canvas_KeyUp（object sender，KeyEventArgs e）
 {
 //检查具体的 v'键，然后检查修饰符
 if（e.Key == Key.V）{
 if（（Keyboard.Modifiers& ModifierKeys.Control）== ModifierKeys.Control）{
 //具体的Ctrl + V动作这里
} 
} //其他忽略击键
} 
  

I have a Silverlight application in which I catch certain key presses such as Tab or Ctrl to perform some action. However, I want to be able to handle multiple keys pressed at the same time such as Ctrl + R or something like that. Is there any way to do that in Silverlight, and if so, how?

解决方案

Take a look at the ModifierKeys Enumeration to check for multiple key press combinations. See Silverlight Keyboard Support for code samples and more information.

void Canvas_KeyUp(object sender, KeyEventArgs e)
{
    //check for the specific 'v' key, then check modifiers
    if (e.Key==Key.V) { 
        if ((Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control) {
        //specific Ctrl+V action here
        }
    } // else ignore the keystroke
}
