flash mx 2004 pro - preloader - how to

[fh]

Many people ask me very often how to build a dynamic preloader. Here is a first shot.
Comments are appreciated.

Code: [Select]


//import the classes from folder:
//C:\Program Files\Macromedia\Flash MX 2004\en\First Run\Classes\mx\controls
import mx.controls.ProgressBar;
import mx.controls.Loader;
//stop the timeline
stop();
//Create a Progressbar component:
createClassObject(ProgressBar, "pBar", 2);
pBar._x=200;
pBar._y=200;
//Create a Loader component
createClassObject(Loader, "loader", 3);
loader._x=200;
loader._y=200;
loader.visible = false;

//Create a listener
loadListener = new Object();
//create a progress function/handler
loadListener.progress = function(eventObj){
 _root["pBar"].setProgress(_root.loader.bytesLoaded, _root.loader.bytesTotal); // show progress
}
loadListener.complete = function(eventObj){
   pBar.visible=false;
   loader.visible = true; //here code masks if you want more nice look
}
//add the progress-handlers to the loader
loader.addEventListener("complete", loadListener);
loader.addEventListener("progress", loadListener);

//load the swf file
loader.contentPath = "name.swf";

Nice Micheal..
I like the style - the combination of loader component and progressbar to deliver a preloader

Hi,

I cannot believe that mere addition of a progressbar compoment  gets some info that  would not be available otherwise, but I have no way to test this.
So I have set up a slow jpeg source at http://wolfgang.remsnet.de/slow.php - as the name implies it  delivers a jpeg image but takes a couple seconds (even on fast links) - if anybody wnts to see how the preloader behaves
