[Tweener] Tweener Events??

[Patrick J. Jankun]

Hi,

Im sure that this questions falls few time, but, since i couldn't find 
any post that has the topic, here is my Question:
Is the Tweener itself dispatching any kind of Events when an tween 
target is done tweening? Im not asking about Callbacks!
I want register an event listener that lists for events from the tween 
target, like tweening begins, tweeing is done.

Can anybody pinpoint me to some solution?

thanks in advance,
Patrick
