Storing a callback function as a class member

[Nathan Huesken]

Hi,

I have a class, where I want to store a callback function as a member
to access later:

class CallbackClass:
def setCallback(self,cb):
self.cb = cb

def callCallback(self, para):
self.cb(para)

Doing so, I get the error:
callbackFunc() takes exactly 1 parameter (2 given)

self is given as parameter this way, is it not? How can this be done?

Thanks!
Nathan
