Actually, I do. It's not got very far yet, as it's extremely confusing
and time consuming and I just haven't had the time to do it.

As the other poster has pointed out, the C layer is what the Ada code
interfaces with. Inside the Ada layer it is then possible to inherit
from the C++ classes.

The idea of wxAda is provide wxWidgets for any Ada compiler, not just
those that *can* import C++ libraries - but saying that, when you
interface with C++ libraries you end up with a C++ like library in Ada
- not very Ada like.
