Two ways... 1. Make the receiver visible to C++ and use QObject::connect(), ie. decorate the slot with pyqtSlot(). 2. Make the transmitter visible to Python and PyObject_Call() the signal object, ie. convert the transmitter to a Python object. Note that this will only work if there are .sip bindings for the transmitter. > My current approach is to use sipQtAPI::qt_connect, and to do this I > need to apparently convert the C++ object to a PyObject using SIP.
