Here's a complete working example to start with...
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute"
applicationComplete="TabOnglet()">
<mx:Script>
<![CDATA[
import mx.events.IndexChangedEvent;
import mx.containers.TabNavigator;
import mx.containers.Canvas;
import mx.controls.Button;
public function TabOnglet():void
{
this.setStyle("borderStyle" , "solid");
//this.percentHeight = 100;
this.percentWidth = 100;
this.createTab(new TabNavigator());
//create an listen to the event
this.initEventListener();
}
/**
*
* @param tabNavigator
*
*/
private var _myTab:TabNavigator;
private function createTab(tabNavigator:TabNavigator) : void
{
_myTab = tabNavigator;
_myTab.percentHeight = 100;
_myTab.percentWidth = 100;
var canvas1: Canvas= new Canvas();
canvas1.percentHeight=100;
canvas1.percentHeight = 100;
canvas1.percentWidth = 100;
canvas1.label = "BPMN";
var canvas2: Canvas= new Canvas();
canvas2.percentHeight=100;
canvas2.percentHeight = 100;
canvas2.percentWidth = 100;
canvas2.label = "BPEL";
canvas2.id="bpel";
tabNavigator.addChild(canvas2);
tabNavigator.addChild(canvas1);
this.addChild(tabNavigator);
tabNavigator.addEventListener(Event.CHANGE, changed);
}
private function changed(evt:IndexChangedEvent):void{
trace("Tab changed from (" + evt.oldIndex + ") to (" +
evt.newIndex + ")");
}
/**
* initialise the event
*
*/
private function initEventListener() : void
{
trace(this + " cré un écouteur");
// trace(_myTab.getTabAt(1) +
"------------------------this.getTabAt(1)______________r");
//this.addEventListener(MouseEvent.CLICK, interceptClick, true);
// var tab:Button = _myTab.getTabAt(1);
// tab.addEventListener(MouseEvent.CLICK,interceptClick);
//this.getChildAt(1).addEventListener(MouseEvent.CLICK,
interceptClick, true);
}
