Pickle and Instance Methods

[Steve Potter]

I have a class that I am trying to pickle. One of the attributes is
used to set a callback e.g.
self.attribute.setCallback(self.callbackfunction).
I understand that this cannot be saved by pickle.
My question is, is there another way of setting a callback that would
agree with pickle?
If not is there some way to make pickle ignore the problem attribute?


Thanks,

Steve

Try adding a __getstate__ method to your class:
