[Passing arguments on event triggered functions - AS3]

If I may, I'd like to contribute to this old topic with an alternate solution for the record. It's actually more like "the other way around" of GreenSock's solution. I think you guys might find it interesting.

function blurToX(mc:MovieClip, amount:Number):Function {
	return function(event:MouseEvent):void {
		TweenMax.to(mc, 1, {blurFilter:{blurX:amount}});
	};
}
var overHandler:Function = blurToX(myClip, 100);
myButton.addEventListener(MouseEvent.ROLL_OVER, overHandler);
//myButton.removeEventListener(MouseEvent.ROLL_OVER, overHandler);

And on the second case:

function movBar(pos:Number, wid:Number):Function {
	return function(event:MouseEvent):void {
		TweenLite.to(orangeBar, .5, {x:pos, width:wid});
	};
}
btn_about.addEventListener(MouseEvent.ROLL_OVER, movBar(39, 51.5));
btn_portfolio.addEventListener(MouseEvent.ROLL_OVER, movBar(140.5, 81.5));
btn_approach.addEventListener(MouseEvent.ROLL_OVER, movBar(255.5, 81));
btn_blog.addEventListener(MouseEvent.ROLL_OVER, movBar(350.5, 9));
btn_contact.addEventListener(MouseEvent.ROLL_OVER, movBar(440, 71));
