Hey Tanu. Ok, I'm almost there. So I replaced the following in the
Python application to receive signals...

myProjectProxy.connect_to_signal(
    DBUS_SIGNAL_NOTIFICATION, 
    self.onDBusSignal, 
    dbus_interface=DBUS_INTERFACE)

...with this...

self._sessionBus.add_signal_receiver(
    handler_function=self.onDBusSignal,
    signal_name="SomeSignal",
    dbus_interface=DBUS_INTERFACE,
    bus_name=DBUS_SERVICE_NAME,
    path=DBUS_OBJECT_PATH)

I think that's right, with the constants as such:

DBUS_SERVICE_NAME = "com.myproject.MyProjectService"
DBUS_OBJECT_PATH = "/com/myproject/MyProjectObject"
DBUS_INTERFACE = "com.myproject.MyProjectInterface"

Does that look right? I'd test it, but I can't because the C++
application still needs to answer the Introspect message which I'm not
sure how to do yet.
