在Mac上的Adobe AIR命令鍵

Question

我目前正在開發和AIR應用程序爲我需要檢測命令鍵組合鍵，目前我根據文檔事件有這樣的事情

this.addEventListener(KeyboardEvent.KEY_UP, onKeyUp); 

protected function onKeyUp(event:KeyboardEvent):void 
{ 
    if(event.ctrlKey){ 
    switch(event.keyCode){ 
     case Keyboard.C: 
     trace("need to copy"); 
     break; 
    } 
    } 
} 

.ctrlKey，應檢測命令和控制鍵在Mac上，如果我按組合控制+ C的工作，但如果我使用命令+ C沒什麼，我也試過

event.commandKey 

我想，也許在內置在菜單中給我一些麻煩，我刪除然後仍然沒有，我失蹤了什麼？感謝您的任何幫助

我也面臨同樣的問題，並通過爲剪貼板鍵添加本機菜單事件爲此做了一個解決方法。正如你所說的，「event.ctrlKey」不適用於MAC，並且「命令鍵」與C（複製）結合使用，V（粘貼），X（剪切），W（關閉），M（最小）將一直聽取AIR應用程序的本地菜單事件（buildIn菜單事件）。所以我添加了菜單選擇事件。
