Please send your replies to the list as well (use reply-all). You need to pass a pointer to the second widget in the user parameters when connecting to the first widget. A simple example would be: g_signal_connect(win_b_button, "clicked", win_b_clicked_cb, win_a_label); void win_b_clicked_cb(GtkButton *b, gpointer *user_data) { gtk_label_set_label(GTK_LABEL(user_data), "Button was clicked"); } Typically, programs will create a structure containing pointers for all widgets they use, then pass a pointer to this structure to all the signal handlers. -Jim _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
