I just ran into a similar situation; whether it is similar enough is for
you to judge. I have a manager class that opens 2 Morphs; when one of
them (a SystemWindow) is killed I wanted the other one killed as well.
I made my manager the model of the SystemWindow morph. When the
SystemWindow is destroyed, it sends #windowIsClosing to its model (i.e.,
my manager). The manager can implement #windowIsClosing to delete the
This may or may not be an advisable use of the model mechanism, but it
seems to work.
