Re: [Pyobjc-dev] Kill Thread on Exception

[Koen B. <ko...@ma...>]

Hey Ronald,

I am playing around with this and it seems to work. But how can I make  
all my NSObjects to add this method? I tried importing this in  
AppName.py but the methods do not get added to underlying modules. Do  
I need to import this wherever I use it after importing any other  
classes based on NSObject?

If anyone runs into the same get the script here: http://pastie.caboo.se/149814
