Hi Peter, There are two methods which can be used for this purpose. #outOfWorld: #announceDeleted
Both are called recursively down the morph tree from the window. If you need to stop the window or provide a dialog then you should create a subclass of Model and use that to keep references to things that need cleanup and control the closing and other events.
