BTW tree_view.get_selection().lock()->set_mode(...); would be the same as ptr = tree_view.get_selection().lock(); assert(ptr != NULL); ptr->set_mode(...); The assertion is actually included in the operator->() of the boost smart pointer. This is somewhat safer than using "simple" pointers, because in this case you are guaranteed that your program will halt with a failed assertion, instead of randomly access to an invalid memory area. _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
