i implement this solution a couple times and works ok but i found a better solution to do this in a elegant way , using a modification of the create function of the Delegate class.

function DelegateCreate(t:Object, f:Function,args:Array):Function
{
return function():Void
{
if ((args == undefined) || (args == null))
args=[]
var _newArgs:Array = args.concat(arguments);
f.apply(t, args);
};
}

var movie_clip.onPress=DelegateCreate(this,onPressFunc,[1,2,3,4,"cool"] )

and here is the function

function onPressFunc(arg1,arg2,arg3,arg,4,arg5)
{
//N args of any king or type that you pass using the parameter array.

}

Awesome! Thanks for posting this, I had always wondered about that and never found a reason. I had all kinds of kludgy
workarounds previously, but now this makes sense and I’m using it. AS3 gets rid of Delegate, but this is great until we
all make the transition.

Well, guess this blog doesn’t like < signs. Let me try this again. Easy:

private function drawMenu():Void {
var len:Number = 0;
var x:Number = 0;
__buttonArray = new Array();
for (var i:Number = 0;i var button = __instance.attachMovie(’myButton’, ‘myButton’+i+’_mc’, i);
button._x = x;
button.label = ‘Button ‘ + i;
x += button._width;
__buttonArray.push(button);
var clickDel = button.onRelease = Delegate.create(this, buttonClicked);
clickDel.id = i;
}
}

private function buttonClicked():Void {
var id:Number = arguments.caller.id;
trace(’The id for the selected button is: ‘ + id);
trace(’The path to this button is: ‘ + __buttonArray[id] + ‘ or ‘ + __instance['myButton'+id+'_mc']);
}

Hope this helps, and I hope your blog doesn’t blow up again when I submit this

What happens if you are trying to set up a number of buttons within a for loop and want to pass the id of each button using the Delegate class? For example:

import mx.utils.Delegate;

class Whatever extends MovieClip {

private var someClip_mc:MovieClip;
private var someList:Array;

function Whatever() {
for(var i=0; i
