private var timer:Timer;

private function init():void {
timer = new Timer(10);
timer.addEventListener(TimerEvent.TIMER, timer_timer);
}

private function timer_timer(evt:TimerEvent):void {
progressBar.setProgress(progressBar.value + 1, 100);
}

private function progressBar_complete(evt:Event):void {
timer.stop();
}

private function resetProgressBar():void {
progressBar.setProgress(0, 100);
progressBar.scaleX = 1.0; // 100%
progressBar.scaleY = 1.0; // 100%
progressBar.alpha = 1.0; // 100%
}

private function playProgressBar():void {
resetProgressBar();
timer.start();
}
