There are several ways to update a gui from a non-gui even source 1. g_idle_add() - when the gui is idle, poll some source for data 2. use io channels to generate callbacks when data arrives in pipes, files, or sockets -- see http://developer.gnome.org/doc/API/2.0/glib/glib-IO-Channels.html 3. threads, update the GUI through some kind of IPC mechanism (threads and guis are kind of tricky) The following post has an example that spawns a process and puts the process' output into the GTK gui: http://mail.gnome.org/archives/gtk-app-devel-list/2004- March/msg00026.html Michael > > Thanks > -- > View this message in context: > http://www.nabble.com/Fundamentals-of-GTK-t1396951.html#a3756984 > Sent from the Gtk+ - Apps Dev forum at Nabble.com. > > _______________________________________________ > 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
