The buttons are normal GObject so you can attach any piece of user data to them with: g_object_set_data (G_OBJECT (button), "button_id", GINT_TO_POINTER (button_id)); assuming button_id identifies your particular button among the 34. GINT_TO_POINTER is here to fit the integer in a pointer value, which this function expect. Then in the callback handler you can retrieve the button ID like this: button_id = GPOINTER_TO_INT (g_object_get_data (G_OBJECT (button), "button_id")); Hope this helps. cheers, Christophe. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
