Antwort: Re: Antwort: Re: Antwort: Re: [Newbies] closing/deleting a morph and dependents

[Dietmar Schielke]

Hi Edgar,

tx for the code snipets.

I figured something out by my self :-)

1. When a Morph is removed from the world 
outOfWorld: aWorld 
is called on the morph und recursive an all its submorphs.
So I can simply override outOfWorld: in my SubDeviceMorphs.
Im not shur if this is the correct way, but it works.

2. The dependents of an object are held in an weak array so the cleanup i 
want is not realy neccesary.
