just to follow up. I managed to get it working by having a closer look at the xxmodules. However, the example does the following
typedef struct { PyStructBaseClass mBase; int mValue; } PyStructDerivedClass; Does anything speak agains doing this ? typedef struct : public PyStructBaseClass { int mValue; } PyStructDerivedClass; It seems to work for me. The advantage is that access to the members in that structure is easier. The .mBase is not needed .... Cheers Jochen -- http://mail.python.org/mailman/listinfo/python-list
