What Paul ment to say ;-), was that gtk as well as most gui toolkits these days, are implementing a paradigm known as event-driven programming, see http://en.wikipedia.org/wiki/Event-driven_programming . The loop is implemented by the glib main loop. gtk registers its callbacks to the mainloop (button presses etc), but you may add additional callbacks, e.g. from sockets. The mainloop just hangs there until something happen that has been registered to it. Paul is certainly right that you don't have to know the implementation details. Just register your callbacks and trust that everything will work. Regards, Dov On 3/26/06, yinglcs2@xxxxxxxxx <yinglcs2@xxxxxxxxx> wrote: > Thanks.
