addEventListener to loader? or loaded swf?

Question

I am loading an external swf file using the following code:

  //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
  }

Here is the entire code for that .as file

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();
     } 
    }
    }
}

Question 1: Once the loader loads my image, and I click on it, nothing is happening. Am I supposed to be adding the EventListener to the loader or something else?

Question 2: How can I detect the height and width of the swf file in the loader?

Answer 1

1) There is no problems of adding the MouseEvent to the loader, there must have another problem somewhere is the image loaded on the same domain ? Is a parent eating all the event or have a mouseChildren set to false ?

2) For the dimension of the content, once loaded you can do

loader2.content.width and loader2.content.height

Answer 2

To detect when the swf is loaded, use

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

you can listen to other events but you have to use the loader's "contentLoaderInfo" property as this references the object that dispatches the events.

Hope this helps!
