This sample shows how to embed wxPython into a wxWindows application.
This sample shows how to embed wxPython into a wxWidgets application.
There are a few little tricks needed to make it work, but once over
the hurdle it should work just fine for you. I'll try to describe the
build issues here, see the code and comments in embedded.cpp for
examples of how to use it.
1. The most important thing is that your wx application and wxPython
must use the same version and the same instance of wxWindows. That
means that you can not statically link your app with wxWindows, but
must use a dynamic library for wxWindows.

2. You must ensure that your app and wxPython are using the same
wxWindows DLL. By default on MSW wxPython installs the wxWindows
wxWidgets DLL. By default on MSW wxPython installs the wxWidgets
DLL to a directory not on the PATH, so you may have to do something
creative to make that happen. But because of #3 this may not be
that big of a problem.
3. wxPython, your app and wxWindows must be built with the same flags
3. wxPython, your app and wxWidgets must be built with the same flags
and settings. This probably means that you will need to rebuild
wxPython yourself. It may be possible for me to distribute the
setup.h and etc. that I use, but you'll need to rebuild everything
yourself anyway to get debugger versions so I'm not too worried
about it just yet. BTW, on MSW if you do a FINAL=0 build (full
debug version) then you will need to have a debug version of Python
built too since it expects to have extension modules in files with
a _d in the name. If you do a FINAL=hybrid build then you will be
able to use the stock version of Python, but you won't be able to
trace through the PYTHON API functions.

4. I expect that most of these issues will be much more minor on
Unix. ;-)
