the not very clearly named sigc::trackable::notify_callbacks() gets close to this, but is intended to be called from the destructor of a trackable or derived type. it will cause all connections to the signals of the object it is called for to be dropped. sigc++ keeps track of the connections, you see. but note: i do mean *all* connections. you have no control over which ones. _______________________________________________ libsigc-list mailing list libsigc-list@gnome.org http://mail.gnome.org/mailman/listinfo/libsigc-list
