updating byte count on label through ProgressEvent

Question

Hi, I have main.mxml and an external class com.audio.AudioPlayer.as

AudioPlayer loads an audio file and has an event for counting bytesLoaded and bytesTotal.

I would like to push the bytesLoaded information continuously as its being loaded into a label on main.mxml from the ProgressEvent.PROGRESS

snd.addEventListener(ProgressEvent.PROGRESS, listenProgress);


    private function listenProgress(event:ProgressEvent):void
 {
  progressID.text = event.bytesLoaded + " / " + event.bytesTotal;
 }

I can't find a way to target the label control in main.mxml, from inside AudioPlayer and to continuously update the byte count.

Any help, much appreciated...

Answer 1

Create a bindable variable in AudioPlayer and set it to the correct value in your event handler.

In your mxml, bind the label's text to that value.

Answer 2

ok I figured out a work around. In AudioPlayer.as I declared:

public var snd:Sound = new Sound();

in main.mxml I added the event listeners for snd:

newAudio.snd.addEventListener(Event.COMPLETE, onSoundComplete);
newAudio.snd.addEventListener(ProgressEvent.PROGRESS, listenProgress);

... in doing so I can update my mxml control by declaring:

[Bindable] private var progUpdate:String;

<mx:Label text="{progUpdate}" x="254.75" y="46" width="506.5" />

so basically I just moved the eventListeners from the AudioPlayer class and into the document class.
