Hi, and you :)

Well, to try to automate it using python scripts (if this doesn't work
another attempt with SWIG). Rather than define all tagged types as
non-limited types, they will be limited and they will have to
allocated
dynamically, this is how other bindings to C++ UI toolkits work and
really is the only way due to C++ semantics.

Yeah, bit job due to the size of wxWidgets, although I have no
intentions
of supporting the entire lib, there's stuff wxAda just doesn't
require.

Yup, the license and also the ease of programming with wxWidgets is
what
got me started with it in the first place.

I think atm, your options are this:

1) Use AdaGtk on all platforms for now.
2) Develop your UI code in whatever language for whatever platform,
e.g.
C++ for Win32, Obj-C for Apple and then create the app code in Ada
providing
some sort of interface between the 2.
