but thats exactly what you would be doing. the slot would have a RefPtr stored within it that kept the refcnt up and thus the object alive. in boost, you can use weak_ptr<T> to get around this, but RefPtr (AFAIK) has no equivalent in part because its not intended to be a general purpose shared pointer implementation. _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
