If it is, how?
Assuming you are doing the connection from C++, and assuming that the signal is defined in Python using @pyqtSignal, then once you have a pointer to the underlying C++ QObject then just use the normal QObject::connect() call. Pass whatever you defined the signal to be using @pyqtSignal to your SIGNAL() call in C++.
