componentes dinamicamente

Olá Júnior!

Olha, também não estou muito por dentro do AS3.0, mas eu se fosse você iria no F1 do Flash, no livro ActionScript 3.0 Language and Components Reference. Parece que vai ajudar, não é mesmo?

Vasculhando um pouco, descobri o seguinte:

This example demonstrates how to create a List and populate other List instances with its selections.

To run the example, follow these steps:

- Add the List, Button, and Label components to the library.

- Save this code as ListExample.as in the same directory as your FLA file.

- Set the Document class in the FLA file to ListExample.

package
{
import flash.display.Sprite

public class ListExample extends Sprite
{

 import fl.controls.Button;
 import fl.controls.Label;
 import fl.controls.List;
 import fl.data.DataProvider;
 import flash.events.*;

 private var clearButton:Button;
 private var availableItems:List;
 private var selectedItemList:List;
 private var selectedItemsList:List;

 public function ListExample() {
 createComponents();
 setupComponents();
 }

 private function setupComponents():void {
 var dp:Array = new Array();
 var i:uint;
 var count:uint = availableItems.rowCount * 2;

 for (i = 0; i < count; i++) {
 dp.push({label:"Item " + i});
 }

 availableItems.allowMultipleSelection = true;
 availableItems.dataProvider = new DataProvider(dp);
 availableItems.dataProvider = new DataProvider(dp);
 availableItems.addEventListener(Event.CHANGE, updateLists);
 clearButton.addEventListener(MouseEvent.CLICK, clearHandler);
 }

 private function clearHandler(event:MouseEvent):void {
 availableItems.clearSelection();
 // clear data providers
 selectedItemList.dataProvider = new DataProvider();
 selectedItemsList.dataProvider = new DataProvider();
 }

 private function updateLists(e:Event):void {
 selectedItemList.dataProvider = availableItems.selectedItem ? new DataProvider([availableItems.selectedItem]) : new DataProvider();
 selectedItemsList.dataProvider = new DataProvider(availableItems.selectedItems);
 }

 private function createComponents():void {
 clearButton = new Button();
 availableItems = new List();
 selectedItemList = new List();
 selectedItemsList = new List();
 var availableItemsLabel:Label = new Label();
 var selectedItemListLabel:Label = new Label();
 var selectedItemsListLabel:Label = new Label();

 clearButton.move(10,142);
 availableItems.move(10,32);
 selectedItemList.move(120,32);
 selectedItemsList.move(230,32);
 availableItemsLabel.move(10,10);
 selectedItemListLabel.move(120,10);
 selectedItemsListLabel.move(230,10);

 clearButton.label = "Clear Selection"
 availableItemsLabel.text = "Available Items";
 selectedItemListLabel.text = "Selected Item";
 selectedItemsListLabel.text = "All Selected Items";

 addChild(clearButton);
 addChild(availableItems);
 addChild(selectedItemList);
 addChild(selectedItemsList);
 addChild(availableItemsLabel);
 addChild(selectedItemListLabel);
 addChild(selectedItemsListLabel);
 }
	}
}

clearButton = new Button();
clearButton.move(10,142);
clearButton.label = "Clear Selection";
addChild(clearButton);

Abraço
