This is more of design question rather than UI related.
I have my UI implemented using wxPython and I need to integrate with a C++ library that communicates with network device drivers behind the scenes. There are two situations here: 1) Both the UI and the C++ library are on the same system 2) They are on different systems connected through IP remotely. Basically, the C++ tool has the Read and Write methods that I need to trigger from the UI. What is the best way to integrate?
the In the future, the C++ tool needs to serve several clients simultaneously. In this case I guess I need to create a Python wrapper around or in front of the C++ tool to work like a server. Are there any python tools or design patterns to help? I don’t have any web development experience but I can put effort to learn. Your ideas will boost me certainly.
Note, none of this is wx-specific, it might be worth inquiring on other fora.
But my thoughts anyway :
If you sometimes need to use a network protocol, you might as well always use it–even when everything is running on the same machine. It’s easy to spin up a sub-process and then talk to it on the localhost.
So what protocol to use?
If the C++ lib already supports one, use that. If not, then you have multiple options. I’d take a look at zeroMq:
You could use C++ on the C++ side and Python on the other side.
You could also use plain TCP.
If you might want to use other, more generic clients or servers, then http could be a good idea. You could use the standard lib’s SimpleHttpServer, or one of the simple, fast web frameworks like flask or tornado.
If you need to put some python around the C++ (I write an http server in c++) then I suggest Cython for calling c++ from python. And maybe XDress for generating the Cython.

I wrote a GUI a few years ago using Python and was using a C++ module that I compiled using the Boost library. You could also wrap any C++ functions with extern ‘C’ and then you can load that function directly with Python using ctypes.

Thank you Chris. That helps. I haven’t heard about zeroMQ. I’ll take a look. Is that an implementation of MPI?

nope -- it's a flexible low-overhead communication protocol.
I don't know much about it except that it has enabled some cool projects
like iPython.
