What exactly is your setting? GUI is written in python and you want to
pass points from there to a c++ class? Is that a QObject descendant
and do you have a reference to it in python? How do you declare the
slot in the c++ class? In case you use custom types for signals/slots
do not forget to call qRegisterMetaType() before connecting. It would
be better to start with a simple case - make sure that sending a
signal without parameters works.
