Cython/Python/C++ - Inheritance: Passing Derived Class as Argument to Function expecting base class

Question

I am using Cython to wrap a set of C++ classes, allowing a Python interface to them. Example Code is provided below:

BaseClass.h:

#ifndef __BaseClass__
#         


        

Answer 1

Your code, as written, doesn't compile. I suspect that your real PyDerivedClass doesn't really derive from PyBaseClass as if it did that last line would have to be

(self.thisptr).SetObject(inputObject.thisptr)

This would also explain the type error you're getting, which is a bug I can't reproduce.
