I'm using wxPython for my GUI. I have tried running the model thread in the background. But how will I save the state if the whole model is running on a thread? When the program is restarted I want the program to continue from the same state where it left off for each cell. I was thinking of having an idle thread that calls a poll method which polls all the cells and checks what each one is doing. But, I don't know how to do that. I'm confused. -- https://mail.python.org/mailman/listinfo/python-list
