Собственно сабж???
(mx.controls.Button конечно =))
Вроде как:

/**
* sets the associated label text
* @tiptext Gets or sets the Button label
* @helpid 3046
*/
	[Inspectable(defaultValue="Button")]
	function set label(lbl:String)
	{
		setLabel(lbl);
	}

/**
* @private
* sets the associated label text
*/
	function setLabel(label:String):Void
	{
		if (label=="")
		{
			labelPath.removeTextField();
			refresh();
			return;
		}

		if (labelPath == undefined)
		{
			var lp =  createLabel("labelPath", 200, label);
			lp._width = lp.textWidth + 5;
			lp._height = lp.textHeight +5;
			
			if (initializing)
				lp.visible = false;
		}
		else
		{
			delete labelPath.__text;
			labelPath.text = label;
			refresh();
		}
	}

(однако)В коде:

MyButton.setLabel("NEWLABEL");

- ноль имоций ((
P.S. сорри за глупый вопрос конечно
