Me gusto mucho y encontre que en la misma pagina daban el codigo fuente, me alegre ya que dije, voy a ver como esta realizado.
Claro que Flex no lo habia tocado mucho, ya que por tiempo o a veces por ganas, esta vez me decidi a verlo, me lo baje y me instale la Demo de Flex.
Abri el documento mxml, me fije que no había incluido los .as, asi que lo añadi y puse los <mx:
quedando asi
Código :
<?xml version="1.0" encoding="utf-8"?>
