вариант:

import mx.events.EventDispatcher
class XMC {
	var md:Number
	var dt:Number
	
	function XMC(t:Number){
		mx.events.EventDispatcher.initialize(this)
		md=getTimer()
		dt=t
		var r=this
		Mouse.addListener(r)
		r.onMouseDown=function(){
			if(getTimer()-md<dt){
				var eventObject:Object = {target:r, type:'onDoubleClick'};
				dispatchEvent(eventObject);
			}
			else md=getTimer()
		}
	}
	function dispatchEvent() {
	}
	function addEventListener() {
	}
	function removeEventListener() {
	}
}

в кадре:

var cd:XMC = new XMC(300);
var listener:Object = new Object; 
listener.onDoubleClick = function(event) {
	trace("double click");
}
cd.addEventListener("onDoubleClick",listener);
