as3組件事件錯誤

Question

我在我的項目中構建一個表單。在舞臺上我有一些複合框，一個複選框和一個單選按鈕。

當我實時運行應用程序時，我得到這一個錯誤。 1046：未找到類型或不是編譯時常量：ComponentEvent。

我不確定是什麼導致了這個錯誤，因爲我已經導入了ComponentEvent。

代碼如下。你能告訴我如何解決這個錯誤。謝謝。

package { 

    public class Flash_Main { 



     import fl.motion.MotionEvent; 
     import flash.events.Event; 
     import flash.text.TextFormat; 
     import fl.data.DataProvider; 
     import fl.ComponentEvent; 

     public function Flash_Main() { 
     // Building the components 

    var tf:TextFormat = new TextFormat(); 
    tf.font = "Arial"; 
    tf.size = 16; 
    tf.color = 0x000000; 

    var monthA=  

      ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]; 

    monthCB.dataProvider.dp; 

    var dataA:Array = []; 
    setDatesF(31); 
    function setDatesF(n:int):void { 

    for (var i:int=1; i<=n; i++) { 

     dataA.push(i); 

    } 

dp=new DataProvider(dataA); 

dateCB.dataProvider=dp; 

} 

    var yearA:Array = []; 
    for (var i:int= 1910; i<2014; i++) { 

    yearA.push(i); 

    } 

    dp = new DataProvider(yearA); 

    yearCB.dataProvider=dp; 


    monthCB.addEventListener(Event.CHANGE,monthF); 

    function monthF(e:Event):void { 

    var d:Date = new Date(yearCB.selectedLabel,1+monthA.indexOf(monthCB.selectedLabel),0); 

    setDatesF(d.date); 

    } 

    var items:Array = [ 
{label:"London", data:"LondonData"}, 
    {label:"Paris", data:"ParisData"}, 
    {label:"New York City", data:"New York CityData"}, 
    { 
];      
    aBb.DataProvider = new DataProvider(items); 

    aBb.addEventListener(ComponentEvent.ENTER, onAddItem); 

    function onAddItem(event:ComponentEvent):void { 
    var newRow:int = 0; 
    if (event.target.text == "Add") { 
     newRow = event.target.length + 1; 
      event.target.addItemAt({label:"" + newRow, data:"Data" + newRow}, 
     event.target.length); 
    } 
} 

    aCb.addEventListener(MouseEvent.CLICK, clickHandler); 

    aCd.enabled = false; 
    aCe.enabled = false; 

    function clickHandler(event:MouseEvent):void{ 
     aCd.enabled = event.target.selected; 
     aCe.enabled = event.target.selected; 
    } 
      } 

     } 

    } 

Answer 1

變化

import fl.ComponentEvent; 

到

import fl.events.ComponentEvent;
