Detailed explanation

The Application:




<?xml version="1.0" encoding="utf-8"?>
<mx:Application
    creationComplete="{init()}"
    xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"
    viewSourceURL="srcview/index.html">
    <mx:Script>
        <![CDATA[
            import it.creativesource.ResourceLanguage;
            private function init():void{
               
                ResourceLanguage.setResources(resourceManager);
            }
            private function changeLocale(locale:String):void{
           
                resourceManager.localeChain=[locale];
            }
        ]]>
    </mx:Script>
    <mx:ApplicationControlBar width="400">
        <mx:Image source="{resourceManager.getString('myResources','ICON')}" width="16" height="11"/>
        <mx:Label text="{resourceManager.getString('myResources','TITLE')}"  width="100%"/>
        <mx:Button icon="@Embed('assets/us.png')" label="eng" click="changeLocale('en_US')" />
        <mx:Button icon="@Embed('assets/it.png')" label="ita" click="changeLocale('it_IT')" />
    </mx:ApplicationControlBar>
   
    <mx:Text text="{resourceManager.getString('myResources','CONTENT')}"  width="400" height="240"/>
</mx:Application>
 

The ResourceLanguage class:

package it.creativesource
{
 import mx.resources.IResourceManager;
 import mx.resources.ResourceBundle;
 
 public class ResourceLanguage
 {
  public function ResourceLanguage()
  {
  }
  
  public static function setResources(resourceManager:IResourceManager):void{
   
   
   var myResources:ResourceBundle=new ResourceBundle("en_US","myResources");
   myResources.content['TITLE']="Adobe Flex - English Version";
   myResources.content['CONTENT']="Adobe Flex is a collection of technologies released by Adobe Systems for the development and deployment of cross platform rich Internet applications based on the proprietary Adobe Flash platform. The initial release in March 2004 by Macromedia included a software development kit, an IDE, and a J2EE integration application known as Flex Data Services. Since Adobe acquired Macromedia in 2005, subsequent releases of Flex no longer require a license for Flex Data Services, which has become a separate product rebranded as LiveCycle Data Services.";
   myResources.content['ICON']="assets/us.png";
   resourceManager.addResourceBundle(myResources);
   
   
   myResources=new ResourceBundle("it_IT","myResources");
   myResources.content['TITLE']="Adobe Flex - Versione Italiana";
   myResources.content['CONTENT']="Adobe Flex è un insieme di tecnologie rilasciato da Adobe Systems per lo sviluppo e la diffusione del multi-piattaforma Rich Internet Applications basata sulla proprietà di Adobe Flash piattaforma.

   myResources.content['ICON']="assets/it.png";
   resourceManager.addResourceBundle(myResources);
     
   resourceManager.update();
