WG: Nested Structures Warning (Python, Swig 4.01.)

If the inner union is named (e.g. union tagIntRep { int ivalue; ...) and
%flatnested is used, the getters and setters for the members of the union
are created. Without %flatnested, only the getters and setters for the
union, but not for its members, are created.

So it seems that one has to call %flatnested explicitly and also has to give
the inner structures a name.

Gunther Schütze

Hi,

Yes, Object_intRep_ivalue_set ... are still missing with %flatnested in the
input file.

Hi,

does that still happen if you put %flatnested at the top you your input
file?

(It should be on by default for Python, but who knows)
