thank you very much! very useful!!

If you use linux, you can use timerfd_create() to create pollable timer, create new GSource, attach the descriptor and you got your timer. Set intervals to zero to stop it, descriptor will get no more read events, and you don't even need to detach the source from event loop. You can 'reset' the timer without stopping it first.

So should know that i m attaching the timer to a non default main loop (it is a main loop inside a thread). any ideas will be very helpful. thanks!!! ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
