Hi all. This is another question that arises as part of my efforts to run a GUI application, as well as a dbus-service within the same process. (The other question being at <a href="http://mail.python.org/pipermail/python-dev/2012-December/123287.html">http://mail.python.org/pipermail/python-dev/2012-December/123287.html</a>) For a recap of the brief history, I have a parent process, that is spawning a child process via "subprocess". Currently, the child-process is a GUI process; however, I intend to "behave" it as a dbus-service as well. Thus, a) I subclassed the child-process "main" class with "dbus.service.Object"; however, I then got the error "<code>metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases</code>" b) I then used composition, wherein another class, "RemoteListener" deriving from "dbus.service.Object" was made an attribute of the "main" class. That worked. However, when I do dbus.mainloop.glib.DBusGMainLoop(set_as_default=True) GObject.mainloop.run() in the "RemoteListener"'s __init__ method, the GUI of the "main" class fails to load (apparently, because the "mainloop.run()" causes the singular, main-thread to go into busy-wait). c) I tried option b), but now instantiating "RemoteListener" in a separate thread; however, no improvement :( Is there a way to run GUI and a dbus-service together? Or is a dbus-service pure "backend" process? :P I will be grateful for any pointers; if you need me to test anything else, please let me know, I will be more than willing :) Regards, Ajay
