Thanks to all of you! Based on your feedbacks, I was able to find a solution :-)
So here is on how to get your hands on a dbus system object in a
python-based hildon-home widget in a way that you can attach
callbacks.
from dbus.mainloop.glib import DBusGMainLoop
dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)
dbus.mainloop.glib.threads_init()
class YourHomePlugin(hildondesktop.HomePluginItem):
def __init__(self):
self.bus =
dbus.bus.BusConnection("unix:path=/var/run/dbus/system_bus_socket")
This means that auto-recording now works in my Recaller widget...
I'll post a new version to Extras-Devel during the next days.
Thanks again to everybody!
-Tom
