"With all due respect" this is fine, but I am not sure what more your interlocutor can say. If your code works with g_idle_add() but not with g_main_context_invoke_full() then you have a timing issue in your code caused by the fact that the callbacks for the default main loop via g_main_context_invoke_full() may be executed before the callbacks for earlier invocations of g_idle_add(). If it doesn't work with either of them then you have some other issue. It is possible you have found a bug in glib but more likely you have found a bug in your code. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
