The documentation is here: http://developer.gnome.org/doc/API/2.0/glib/glib-The-Main-Event-Loop.html#g-idle-add The idea is that you call g_idle_add() in your worker thread with a callback (function pointer and data) which you want to execute in the main program (GUI) loop. A simple example would be to call: g_idle_add((GSourceFunc)g_print, "Hello\n"); If you call this in the worker thread, it will print "Hello" in the GTK+ main program thread (you must have called g_thread_init(NULL) first). It is the standard way of passing events to the GUI thread. Incidentally, instead of using pthreads, you can use the platform independent GThread implementation.
