Passing args with event ?

[AlsoGaiusCoffey]

To anyone that ended here looking for a simple solution to a problem like Andreq85's, it does exist:

var someHandlerFunc:Function = someFunc(someArgs);
myBtn.addEventListener(MouseEvent.CLICK, someHandlerFunc);
//myBtn.removeEventListener(MouseEvent.CLICK, someHandlerFunc);

function someFunc(someArgs:Object):Function {
    return function(e:MouseEvent):void {
        trace(someArgs);
    };
} 

For multiple elements you can do:

btn1.addEventListener(MouseEvent.CLICK, addPage(1));
btn2.addEventListener(MouseEvent.CLICK, addPage(2));
btn3.addEventListener(MouseEvent.CLICK, addPage(3));

function addPage(_nPage:int):Function {
    return function(e:MouseEvent):void {
        nPage += _nPage;
    };
} 

Nifty trick for a one-off, and for lazy prototyping, but I think it would be a bit risky for a production system as it makes clean up code rather tough eg: it's rather tough to find a function reference to removeEventListener!

All the same, thanks for some food for thought.
