addEventListener加載器？或加載瑞士法郎？

Question

我使用下面的代碼加載外部swf文件：

//add close button 
    var reqButton:URLRequest = new URLRequest(btn_close); 
    var loader2:Loader = new Loader(); 
    loader2.load(reqButton); 
    addChild(loader2); 

    loader2.addEventListener(MouseEvent.CLICK, closeInfoBubble); 

    function closeInfoBubble(event:MouseEvent):void 
    { 
    infoClip.removeMarkerObject(infoBubble) 
    infoBubble = null 
    } 

這裏是整個代碼。至於文件

package com.modestmaps 
{ 
     import com.modestmaps.overlays.MarkerClip; 

     import flash.display.Graphics; 
     import flash.net.URLRequest; 
     import flash.display.Loader; 
     import flash.display.Shape; 
     import flash.display.Sprite; 
     import flash.filters.BlurFilter; 
     import flash.geom.Matrix; 
     import flash.geom.Rectangle; 
     import flash.text.TextField; 
     //import mx.core.Application; 
     import mx.core.Application; 
     import flash.events.MouseEvent; 


public class InfoBubble extends Sprite 
{ 
    private var btn_close:String = "http://www.cvcmaps.com/SabineParish/media/close_button.swf"; 
    public var textField:TextField; 
    public var background:Shape; 
    public var shadow:Shape; 
    public var infoClip:MarkerClip; 

    protected var map:InfoMap; 
    //var infoClip:MarkerClip; 
    public var infoBubble:InfoBubble; 
    public function InfoBubble(urlLink:String) 
    { 
     //the name of my markers are set to the links of the swf files in which I want to load into the infobubble 
     this.name = urlLink; 
     this.mouseEnabled = false; 
     this.mouseChildren = true; 
     this.buttonMode=false; 

     shadow = new Shape(); 
     shadow.filters = [ new BlurFilter(16, 16) ]; 
     shadow.transform.matrix = new Matrix(1, 0, -0.5, 0.5, 0, 0); 
     addChild(shadow); 

     background = new Shape(); 
     addChild(background); 

     textField = new TextField(); 
     textField.selectable = false; 
     //the infobubble is still sized according to the textField.width and height 
     //I don't know how to get the size of the loaded swf 
     textField.width = textField.textWidth+432+4; 
     textField.height = textField.textHeight+288+4; 

     //add main swf 
     var request:URLRequest = new URLRequest(urlLink); 
     var loader:Loader = new Loader(); 
     loader.load(request); 
     addChild(loader); 

     //position the main swf 
     //current measurements of swf file w432 h288 
     loader.y = -288 - 37; 
     loader.x = mx.core.FlexGlobals.topLevelApplication.LBloaderX; 

     //add close button 
     var reqButton:URLRequest = new URLRequest(btn_close); 
     var loader2:Loader = new Loader(); 
     loader2.load(reqButton); 
     addChild(loader2); 

     loader2.addEventListener(MouseEvent.CLICK, closeInfoBubble); 

     function closeInfoBubble(event:MouseEvent):void 
     { 
     infoClip.removeMarkerObject(infoBubble) 
     infoBubble = null 
     } 
     //position the closebutton swf 
     //current measurements of closebutton swf file w18 h18 
     loader2.y = -286 - 37; 
     loader2.x = mx.core.FlexGlobals.topLevelApplication.LBloader2X; 

     // remember that things in marker clips are positioned with (0,0) at the given location 
     textField.y = -textField.height - 35; 
     textField.x = -10; 

     //I need to find out how to detect the width and height of the swf file loaded into loader2 
     //instead of the size of the textField 
     var rect:Rectangle = textField.getRect(this); 

     // get your graph paper ready, here's a "speech bubble" 
     background.graphics.beginFill(0x12345); 
     shadow.graphics.beginFill(0x000000); 

     for each (var g:Graphics in [ background.graphics, shadow.graphics ]) { 
      g.moveTo(rect.left, rect.top); 
      g.lineTo(rect.right, rect.top); 
      g.lineTo(rect.right, rect.bottom); 
      g.lineTo(rect.left+15, rect.bottom); 
      g.lineTo(rect.left+10, rect.bottom+15); 
      g.lineTo(rect.left+5, rect.bottom); 
      g.lineTo(rect.left, rect.bottom); 
      g.lineTo(rect.left, rect.top); 
      g.endFill(); 
     } 
    } 
    } 
} 

問題1： 一旦加載器加載我的形象，我點擊它，什麼都沒有發生。我應該將EventListener添加到加載器還是其他的東西？

問題2： 如何檢測裝載程序中swf文件的高度和寬度？

Answer 1

要檢測什麼時候SWF加載，使用

loader.contentLoaderInfo.addEventListener(Event.COMPLETE, itemLoaded); 

你可以聽其他事件，但您必須使用加載器的「contentLoaderInfo」屬性，因爲它引用了調度事件的對象。

希望這會有所幫助！

Answer 2

1）將MouseEvent添加到加載程序中沒有問題，那麼必須在加載到同一個域的圖像的某個地方出現另一個問題？ 父母是否吃過所有的事件，或者是否有mouseChildren設置爲false？

2）對於內容的尺寸，一旦加載，你可以做

loader2.content.width和loader2.content.height
