Hi, I I have a view in Flex 3 where I use a tab navigator and a number of views inside the tab navigator. I need to be know which view was clicked because of it's one specific view then I need to take action, i.e. if view with id "secondTab" is clicked then do something.
I have set it up to be notified, my problem is that I need to be able to know what view it is. Calling tab.GetChildByName
or a similar method seems to only get me back a TabSkin
object.
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml"
width="100%"
height="100%"
xmlns:local="*"
creationComplete="onCreationComplete(event)">
<mx:Script>
<![CDATA[
import mx.events.FlexEvent;
import mx.controls.Button;
protected function onCreationComplete(event:Event):void {
for(var i:int = 0; i < myTN.getChildren().length; i++) {
var tab:Button = myTN.getTabAt(i);
tab.addEventListener(FlexEvent.BUTTON_DOWN, tabClickHandler);
}
}
private function tabClickHandler(event:FlexEvent):void {
var tab:Button;
if(event.currentTarget is Button) {
tab = event.currentTarget as Button;
// how do I access the actual view hosted in a tab that was clicked?
}
}

<mx:TabNavigator id="myTN">
<local:ProductListView id="firstTab"
label="First Tab"

<local:ProductListView id="secondTab"
label="Second Tab"
