}

Прослушивание:

myObject.addEventListener(SomeEvent.DO_SOMETHING, myObjectHandler);
 
private function myObjectHandler(e:SomeEvent):void{
	trace(e.property_1, e.property_2);
}

Диспетчеризация:

private function onClick(e:Event):void {
	this.dispatchEvent(new SomeEvent(SomeEvent.DO_SOMETHING, 1203, true));
}
