RE: [flexcoders]Question about the Loader class

[Richard Schutten]

Hi, Abdul,

 

Here is my example code,

 

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml" xmlns="*" layout="absolute">
 <mx:Script>
  <![CDATA[
   import mx.controls.ProgressBar;
   import mx.controls.Image;   
   import flash.events.*;
   import flash.display.*
   
   private function loadImage(url:String) : void {    
    
    var myloader:Loader = new Loader();
    addEventListeners(myloader);
    
    var myprogress:ProgressBar = new ProgressBar();
    myprogress.source = myloader;
    myvbox.addChild(myprogress);
    
    var myurlrequest:URLRequest = new URLRequest(url);
    myloader.load(myurlrequest);
   }
   
   private function addEventListeners(ldr:Loader) : void {
    ldr.addEventListener(Event.COMPLETE, handleComplete);    
   }
   
   private function handleComplete(event:Event) : void {
    
    var myimage:Image = new Image();
    var ldr2:flash.display.Loader = flash.display.Loader(event.target);
    myimage.load(ldr2.content);
    
    myvbox.addChild(myimage);
   }
   
  ]]>
 </mx:Script>
 
 <mx:VBox id="myvbox">
  <mx:Button label="load" click="loadImage(>>THE URL OF IMAGE<<)"/>  
 </mx:VBox>
</mx:Application>

 

Thanx for the quick responses!

 

 

Richard

Hi, Richard

I would like to look at your code, can you post a complete but simple version of your code...

I am sure, Flash Player would not load data if it is already cached. There is something going wrong somewhere...

Does someone has a answer for my question,

I've a question about the Loader class in Flex 2. I've created a simple
project that adds an Image object to a VBox when a button has been clicked.
I load the Image with the content of the Loader. I also connected a
ProgressBar which shows the progress of bytes loaded. The first time i run
the project it works fine. The progressbar is updating when receiving the
bytes. The second time i run this project the progressbar is not updating
because the image has already been cached by internet explorer. But loading
the image takes the same time as when i run my project for the first time.

So here's my question:

Does the Loader class always downloads the image from the given url, even
when the file is cached?
Because when i just type in the url in ie the image is directly loaded.

Thanx

Richard
