[flexcoders] Re: createChildren(): adding 20 identical buttons to panel?

[valdhor]

Here is a quick and dirty example on how to add multiple instances as
well as how to access them after creation:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute"
     xmlns:custom="CustomClasses.*"
creationComplete="onCreationComplete()">
     <mx:Script>
         <![CDATA[
             import mx.controls.Button;

             private function onCreationComplete():void
             {
                 var panelChildren:Array = panelTest.getChildren();
                 for(var i:int = 0 ; i < panelChildren.length ; i++)
                 {
                     if(panelChildren[i] is Button)
                     {
                         trace((panelChildren[i] as Button).label);
                     }
                 }
             }
         ]]>
     </mx:Script>
     <custom:PanelTest id="panelTest"/>
</mx:Application>

PanelTest.as:
package CustomClasses
{
     import mx.containers.Panel;
     import mx.controls.Button;

     public class PanelTest extends Panel
     {
         public function PanelTest()
         {
             super();
             for(var i:int = 0 ; i < 20 ; i++)
             {
                 var b1:Button = new Button();
                 b1.label = "Button " + (i + 1);
                 addChild(b1);
             }
         }
     }
}
