You can add this to the initialize method of your widget, and in the close method unregister all announcers

� self whenWindowChanged: [:w | w whenClosedDo: [ self close ] ].

Ok :)

Then there is a hook in Morph for that I think :)
(and an announcement in Spec when a widget is built)

I guess what Stef means is that he would like to know if there is a way specify custom behavior when a window closes, and then use this for his purpose of unregistering from some announcer.

I do not think it's a UI framework concern to handle model behaviour (like registration to announcement)

Hi ben

I would like to unsubscribe announcement when the window is closed.
Is there a hook for that in Spec?
