how does a composite tell if it is visible? [message #443363]

if a composite is embedded in a layout somewhere in a parent chain - how
can the composite track if it is visible or not? the composite is an
observer and it would like to switch its observing behavior depending on
whether it is visible or not.

i see that:
o setVisible sends put a "show" event - slthough it is not clear to me
which kind of listener to add - but this would require a listener to
every parent on the chain.
o if i listen to every parent - how would i notice a new setParent
somewhere in the chain - i don't see setParent sending out an event.

thanks-
