<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

private function init():void {
var appInfo:LoaderInfo = Application.application.loaderInfo;
/* Just grab the filename from the SWF URL. */
var fileName:String = (appInfo.url).split("/").pop();
/* Convert bytes to kilobytes. */
var kbTotal:String = (appInfo.bytesTotal / 1024).toFixed(2);
info.text = fileName + " (" + kbTotal + "kb)";
}

<mx:Style>
@font-face{
src: url('./fonts/fromFlash.swf');
fontFamily: "Myriad Web Pro";
}

.myriadWebProFromSWF {
fontFamily: "Myriad Web Pro";
fontSize: 24;
}
</mx:Style>

<mx:ApplicationControlBar dock="true">
<mx:Label id="info" />
</mx:ApplicationControlBar>

<mx:Text styleName="myriadWebProFromSWF">
<mx:text>The quick brown fox jumped over the lazy dog.</mx:text>
</mx:Text>
