Here is the list of 4 events that sets the Life Cycle of flex application.

preinitialize
Presinitialize event is triggered / Dispatched before any other events

initialize
Dispatched when the component has finished its constructions and has all initialization properties set, this is done after all the other components have initialized themselves.

creation complete
Dispatched when the component has finished its construction, property processing, measuring, layout, and drawing. This is done when all components have completed their creation.

application complete (where applicable)
Dispatched after the Application has been initialzed

Apart from above these methods are triggered internally. You can override these methods to have better understanding

override protected function createChildren():void
{
		super.createChildren();
}
override protected function childrenCreated():void
{
	super.childrenCreated()
}
override protected function commitProperties():void
{
	super.commitProperties();
}
override protected function measure():void
{
	super.measure();
}
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
{
	super.updateDisplayList(unscaledWidth, unscaledHeight);
}

This code show how to use TextElement, TextBlock, FontDescription, TextBlock, TextLine

package druva{
import flash.display.Sprite;
import flash.text.engine.*;

public class TextTest extends Sprite {

public function TextTest() {

for (var j:int=0; j<=10; j++) {
var myString:String="Flashallys";
var myFormat:ElementFormat = new ElementFormat();

var myFontDesc:FontDescription=new FontDescription('Georgia','normal','italic','device');
myFormat.fontSize=2+2*j;
myFormat.fontDescription=myFontDesc;
myFormat.color = Math.random() * 0xFFFFEE;

var textElement:TextElement=new TextElement(myString, myFormat);
var textBlock:TextBlock = new TextBlock();
textBlock.content=textElement;

var myTextLine:TextLine=textBlock.createTextLine(null,300);

myTextLine.x = 30+(3*(j*(j+1)/2));
myTextLine.y = 150;

addChild(myTextLine);
myTextLine.addEventListener(Event.ENTER_FRAME, onLoop);
}

}
import flash.events.*;
private function onLoop(e:Event) {
e.currentTarget.rotationY += 3;
e.currentTarget.rotation = mouseX;
}
}
}

Flash is great!!

The below code shows how to use the class

import druva.NumberUtil;

trace('500', NumberUtil.getParity(500));
// true
trace('489', NumberUtil.getParity(489));
// false
trace('5', NumberUtil.getParity(5));
//false
trace('1', NumberUtil.getParity(1));
//true
trace('400', NumberUtil.getParity(400));
//false

This is the actual class

package druva {
  import flash.display.Sprite;

  public class NumberUtil extends Sprite{
    public function NumberUtil(){
    }

    public static function getParity(num:Number):String {
		return (num % 2) ? 'odd' : 'even';
	}

  }
}

Convert TextField to Bitmap

package {
	import flash.display.*;
	import flash.display.BitmapData;
	import flash.display.Sprite;
	import flash.text.TextField;
	import flash.text.TextFormat;
	import flash.text.TextFieldAutoSize;

	public class BitmapUtils extends Sprite {
		public function BitmapUtils() {
			addChild(tf2bm('Druva'));
		}
		public function tf2bm(str:String) {
			var fmt:TextFormat;
			var bmd:BitmapData;
			var bm:Bitmap;
			var tf:TextField;

			fmt = new TextFormat();
			fmt.font='Verdana';
			fmt.size=30;

			tf = new TextField();
			tf.text=str;
			tf.setTextFormat(fmt);
			tf.autoSize=TextFieldAutoSize.LEFT;
			bmd=new BitmapData(tf.width,tf.height,true,0);
			bmd.draw(tf);
			bm=new Bitmap(bmd);
			bm.smoothing=true;
			return bm
		}
	}
}
