Hello eka,
perhaps I can cotton up with (btw. is this good english?)
AsBroadcaster, since it is availablefrom flash version 6 and above.
:-)
But I can't find documentations about the set/get syntax you used. But
it works just perfect. And I guess this set and get keywords are
available within all classes, and thus in classes extending MovieClip,
too, right? That is an advantage to addProperty, which is only
available to Object.
You write "In my personnal AS2 OpenSource framework".. I guess, we all
have our own personnal AS2 OpenSource framework at home. :-) Currently
I try to implement layout mechanisms other than absolute coordinates.
This is, why I want this onX events and such things.
Thanks,
Matthias

ooops... ui.addListener(this) ; is no necessary now in your test in my last
message;)
