I was maybe thinking more low-level (e.g. when using a compiled C++ library
without the source code)? All C++ class methods are translated into
(mangled) functions in any case, so as long as Lazarus can wrap these as
methods in a class of its own it should work? It should even be possible to
wrap 2 or 3 C++ classes into one Lazarus class?

Cheers and thanks for the insights so far.
