Thanks for the reply Todd. What about processing the event though? For example if I have:
foo.addEventListener(MouseEvent.MOUSE_DOWN, processResult); But I want to define processResult so that I can pass it a number or an object, how do I use Custom events? The even I'm want to listen for is the moue down event. When I define this listener, I know the value I want to associate with that event. Later on, I won't know it so that when processResult gets called, it needs that extra parameter to work. I'm a bit confused about how to use the custom event there, since I won't be the one dispatching it. --- In [email protected], "twcrone70" <[EMAIL PROTECTED]> wrote: > > Create a custom event that has a field or fields that hold your > parameter(s).
