Ah, good point... I didn't think too much into that... I guess the best thing to do in that case is, as you said, require an explicit slot declaration - that way I can dynamic_cast on connection as well (matching the sigc::slot<> types to the sigc::signal<> to cast to). I'll just template the connect definition and use slot<> as the actual type instead of slot_base... it's a tad messy, but not bad... and forces one to know the signal type.... _______________________________________________ libsigc-list mailing list libsigc-list@gnome.org http://mail.gnome.org/mailman/listinfo/libsigc-list
