Problems with addChild in UIComponent

Question

Hello there
I have this class, which extends UIComponent class, and I
need put a Label inside it, but when I create the label, and add it
using addChild method, the Label isnt shown.
The class name is "Page" and it is child of a class named
"PageManager" (extends UIComponeny) which is a child of another
class named "Magazine" (extends UIComponent) which is a unique
child of "Application" (extends Canvas).
the class source-code:
* Página que carrega o conteúdo passado por XML e
é dinâmica
* @author Thiago Ricieri
* @version 1.0
package sm.display {
//Importação de classes do Library do Flash
import flash.display.Loader;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.net.URLRequest;
import mx.containers.HBox;
import mx.controls.Label;
import mx.core.UIComponent;
* Classe que define o documento que inicializa a revista
public class Page extends UIComponent {
* Atributos
public var pageSide:Number;
public var isBehind:Boolean;
private var infoLabel:Label;
static public var numInstances:Number = 0;
* Construtor da Classe
public function Page() {
super();
infoLabel = new Label();
this.addChild(infoLabel);
infoLabel.text = "some text here " +
numInstances.toString();
infoLabel.setStyle("color", "#ffffff");
infoLabel.y=150;
infoLabel.x=150;
numInstances++;
pageSide = 0;
isBehind = false;
this.addEventListener(MouseEvent.CLICK, clickHandle);
public function loadImage(src:String):void {
var _loader:Loader = new Loader();
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE,
completeHandle);
var request:URLRequest = new URLRequest(src);
_loader.load(request);
//addChild(_loader);
private function completeHandle(e:Event):void{
protected function clickHandle(e:Event):void {
Thanks a lot ;]

Answer 1

cool,
I've discovered the "override protected function
createChildren()", thats cool!
i've created two another classes extending UIComponent and
they didnt need the "override protected function createChildren()"
to attach components to them. This is only aplied on the classes
that I described above, when i try to use the method "addChild()"
to attach a Label.
I've followed the methods from the article, but is not
working the way I like yet.
help ;]
