Preloading Loses Stage

programming flash
1

I am attempting to use one SWF to load another, acting as a preloader. The loader works fine by itself. The content works fine by itself. When you have the loader load the content, the content.stage is null. How do I fix this?

I stole the preloading code from Senocular, because it was the clearest example I found. However, I still don’t comprehend what makes the content SWF appear on top of the loader. Where is the loaded content initialized? It appears to be done automatically.


package 
{
 import flash.display.MovieClip;
 import flash.events.ProgressEvent;
 import flash.display.Loader;
 import flash.display.LoaderInfo;
 import flash.events.Event;
 import flash.text.TextField;
 import flash.net.URLRequest;
 
 
 public class Preloader extends MovieClip
 {
  var request:URLRequest = new URLRequest("Flash Engine 2.swf");
  var loader:Loader = new Loader();
  
  public function Preloader():void
  {
   loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);
   loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
  
   loader.load(request);
  }
  function loadProgress(event:ProgressEvent):void 
  {
   var percentLoaded:Number = event.bytesLoaded/event.bytesTotal;
   percentLoaded = Math.round(percentLoaded * 100);
   txtLoading.text = "Loading... " + percentLoaded + "%";
   trace("Loading: "+percentLoaded+"%");
  }
  function loadComplete(event:Event):void 
  {
   trace("Complete");
   addChild(event.currentTarget.content);
  }
  
 }

Cheers.
