自定義類中的舞臺屬性，不是文檔類

我需要在我的CustomClass中使用stage.width/height，所以我找到了一些關於它的主題。自定義類中的舞臺屬性，不是文檔類

if (stage) 
      { 
       init(ar,firma,kontakt,oferta,naglowek,tekst,dane); 
      } 
      else 
      { 
       addEventListener(Event.ADDED_TO_STAGE, init); 
      }

但在我的情況下，它不會工作，因爲它不是文檔類，我認爲。其他解決方案？

UPDATE：類代碼

你的類是否擴展DisplayObject，它應該在顯示列表中？你是否在顯示列表中控制文檔類或任何DisplayObject，或者它是純邏輯/不可見組件的一部分？ – www0z0k

我的課程擴展了MovieClip，它在顯示列表中。我控制一些按鈕。 –

是你的初始函數採取...休息作爲它的參數？否則，它只需要一個Event類參數，例如：function init（e：Event）：void – Hawks

我希望你從init函數中得到一個錯誤，它需要很多參數，但可能只是得到一個事件。如果您發佈了與源代碼相關的編譯或運行時錯誤，則在此處發佈時會有所幫助。

我認爲這應該爲你工作，我做了一個粗略的版本，你可以從學習和運用到自己的類

public class CustomClass extends MovieClip 
{ 

protected var _company:String; 
protected var _data:Object; 

public function CustomClass(company:String='', data:Object=null) 
{ 
    _company = company; 
    _data = data; 
    if (stage) 
    { 
     init(); 
    } 
    else 
    { 
     addEventListener(Event.ADDED_TO_STAGE, init); 
    } 

public function init(e:Event=null):void 
{ 
    removeEventListener(Event.ADDED_TO_STAGE, init); 
    //do something with _data 
    //do something with _company 
} 

}

希望你可以在這裏看到的理念，把你的構造函數變量當你創建類的時候，如果在舞臺上調用使用這些類變量的init（）或者添加一個將調用init的事件監聽器（這次傳入一個事件），然後使用相同的類變量來做你想。

注意當我不再需要事件偵聽器時，我該如何刪除事件偵聽器。

我得到了「錯誤1120：訪問未定義的屬性事件」。指向addEventListener（Event.ADDED_TO_STAGE，init）; –

確定該錯誤意味着您尚未導入類Event。所以只需添加import flash.events.Event;與您的其餘進口。 – Hawks

是的，我明白了......非常感謝:) –
