Ok convinced. I just had luck(that my app didn't crashed) and bad luck (because I wasn't aware of the misuse). > BTW, why didn't your compiler warn you about the incompatible function > pointer argument in your callback?

And this code doesn't produce a warning: g_signal_connect (dialog, "delete_event", G_CALLBACK(gtk_widget_hide), NULL); And how could it? The gcc can't know which return type the definition of the delete_event expects, can it? Regards, Enrico -- Get my GPG key from http://www.uvena.de/pub.key
