Preload the same movie as in AS2

programming flash
1

I’m working on test.fla, with document class test.as.

I write the following code to test.as

[AS]
package {
import flash.display.MovieClip;
import flash.events.*;
import flash.utils.getTimer;
//Other Main Timeline imports go here! Don’t forget!
public class test extends MovieClip {
public function test() {
this.loaderInfo.addEventListener(Event.INIT, initLoading);
this.loaderInfo.addEventListener(Event.COMPLETE, initApplication);
this.loaderInfo.addEventListener(ProgressEvent.PROGRESS, showProgress);
}
public function initLoading(e:Event){
trace(Event.INIT+getTimer());
}

    public function showProgress(theProgress:ProgressEvent):void {
        var percent:Number = Math.round((theProgress.bytesLoaded / theProgress.bytesTotal )*100 );
        trace(percent + " %");
        this.graphics.clear();
        this.graphics.lineStyle(1, 0x000000, 1);
        this.graphics.beginFill(0x000000);
        this.graphics.drawRect(100,100,percent,10);
    }
    public function initApplication(myEvent:Event):void {
        trace("Loaded !"+flash.utils.getTimer());
    }
}

}[/AS]

The output is as follows:

init339
100 %
Loaded !341

Now my problem is the INIT event is fired at 339 milliseconds.
I need to show a preloader for the first 339 milliseconds.

Can someone help me?
