It is possible to pass a Python callback to C-extensions?

I have a GUI application written in Python (with WxPython) which uses
some low level classes also written in Python. These low level Python
classes are given a pointer to some GUI Python object. The low level
Python classes callback some of the methods of the GUI object. All
Now I want to convert the low level Python classes to C++. I will be
using SWIG to create the marshaling so the top level GUI, written in
Python stays that way.
The problem: is it possible to continue using call backs? The C++ code
would need to call the Python methods back. Is there an easy way to do
This is a little different from extending or embedding. I have a Python
program that uses Python extensions written in C++. This C++ code would
need to pass some information back to the Python code (and currently,
the all-round Python code uses call backs).
My quick review of the SWIG documentation did not help me find a
solution to this.
Thanks in advance for any help.
