Having an odd problem that I solved, but wondering if its the best solution (seems like a bit of a hack).First off, I'm using an external DLL that requires static callbacks, but because of this, I'm losing instance info. It could be import related? It will make more sense after I diagram it: #Module main.py from A import * class App: def sperg(self): self.a = A() app = App() [main loop and such] ----------------------------- # Module A.py import main class Foo: Selves=[] def __init__(self): Foo.Selves.append(self) @staticmethod def chum_callback(nType, nP): # Need to access function / data in app instance app.sperg(nP) # Need to access func data in Foo # I'm pulling 'self' ouf of list made in constructor self = Foo.getSelf(nP) def getSelf(nP): return self.Selves[nP] --------------------------------------------------------------------- So basically I added a list of instances to the base class so I can get at them from the staticmethod. What's bothering me the most is I can't use the global app instance in the A.py module. How can I get at the app instance (currently I'm storing that along with the class instance in the constructor)? Is there another way to do this that's not such a hack? Sorry for the double / partial post :(
Can you show how you pass the staticmethod to the C-function? Is the DLL utilized by ctypes?
I don't see any reason you couldn't use a bound method, which would give you your self, instead relying on global state.
