And static functions can only work with other static variables and functions - nothing can happen to specific instances... And I've not read that signals can propagate to children in libsigc ... It may be easier to maintain a list of pointers somewhere, so I can have direct access... -Sud. _______________________________________________ gtkmm-list mailing list gtkmm-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtkmm-list
