Hi Peter, I think you have two options:
1. Specialize the Window and use your own delete method to do your additional cleaning. This is what I do in Dr. Geo. 2. Use the WindowClosed announcement from system window to catch the signal from the morph you want to clean Hilaire Le 29/07/2018 à 13:35, Peter Uhnák a écrit : > how can a Morph react to its parent window being closed? > > E.g. > > Morph subclass: #MyMorph. > MyMorph new openInWindow > > how can MyMorph cleanup itself on window close? > > I thought Morph>>delete would do the trick, but it is not being called. > > Thanks, > Peter -- Dr. Geo http://drgeo.eu
