Thanks for that example The library I'm using (reSIProcate) also lets me run the event loop in a thread that I create myself Does TelepathyQt provide a mechanism to create threads that can be used this way and if the threads are created by TelepathyQt, is it safe to make calls to things like setStatus() directly? _______________________________________________ telepathy mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/telepathy
