Re: [Discuss-gnuradio] Callback from C++ to Python Passing gr_message_sp

I've been looking at swig.org and gnu.org. What else would be good to look at?

I suppose to implement the callback from C++ to Python, I declare a new class in Python that inherits from gr_feval.

I wonder how we specify in C++ the call to the new class in Python. And how do we pass the gr_message_sptr from C++ to Python code? The example I see shows only simple calls, all from Python.

I'm really feeling lost so some  inputs would help.

You are mistaken.
