I can't get to the sip documentation pages right now, river-bank.demon.co.uk not responding. I can see from Python that sip.transfer takes two arguments.

No. C++ code calls clone() and wants to keep the result for plotting and fitting. Thus a reference to the Python instance needs to be keep alive and not garbage collected. _______________________________________________ PyKDE mailing list [email protected] http://mats.imk.fraunhofer.de/mailman/listinfo/pykde
