You can use the data property, which is normally used in combination
with item renderers or item editors, but nothing says you can't 
use it for something else ;-)

import mx.controls.Button;

private function appInit():void {
var offset:Number = 0;
for (var i:Number=0; i<10; i++) {
var b:Button = new Button();
b.data = {btnIndex:i};
b.y = offset;
b.label = "click me";
b.toolTip = "button "+i;
b.addEventListener(MouseEvent.CLICK, buttonClickHandler);
addChild(b);
offset+=20;
}
}

private function buttonClickHandler(evt:Event):void {
trace("index: "+evt.currentTarget.data.btnIndex);
}

Subject: [flexcoders] passing data to an EventListener

I'm creating a number of buttons programmatically and I'd like to have
a unique value passed along to a function when each one is clicked.

So if I am doing something like:

for (i=0;i<10;i++) {
b = new Button();
b.y = offset;
b.label = "click me";
b.tooltip = "button "+i;
b.addEventListener(MouseEvent.CLICK, butSelect);
addChild(b);
offset+=20;
}

And I want to have, let's say, "i" passed along to the "butSelect"
function, how is that done? I humored myself and tried doing
butSelect(i) but of course the mouseEvent is passed and you're not
allowed to provide any parameters to the function.

Thanks!
