John Mocenigo replied to the topic 'get solver results (newSolverResults) in a DBUS python script' in the forum. 5 months ago

In the process of digging around, it seems like if I install a signal handler in my python script for the 'newSolution' event of the '/KStars/Ekos/Align' object of the DBUS 'org.kde.kstars ' connection, then the arguments passed with that signal should have what I was looking for.

Unfortunately, with all the deprecations to dbus-python and with my limited knowledge of python, I don't seem to be doing it correctly.

For experimentation purposes, I am using this catch-all signal handler"

def signal_handler(*args, **kwargs):
    global results
    for i, arg in enumerate(args):
        print("arg:%d        %s" % (i, str(arg)))
    print('kwargs:')
    print(kwargs)
    print('---end----')
and trying to register it via:
bus = dbus.SessionBus()
bus.add_signal_receiver(signal_handler,
                            signal_name='newSolution',
                            bus_name='org.kde.kstars',
                            dbus_interface='org.kde.kstars.Ekos.Align',
                            path='/KStars/Ekos/Align',
                            interface_keyword='interface',
                            member_keyword='member',
                            path_keyword='path',
                            message_keyword='msg')
Either I am not registering the handler properly or I need to get an additional thread involved. It just isn't clear to me how to do that.

Any help is appreciated.
