Well, if that can be done then I'm all for it. However, I can't find any references to boost's signal/slot mechanism, do you have some URLs? Sigc++ is very nice code, it's robust and has been around for ages, it'd be a shame to remove it. If it's the upgrade that you're concerned about there are only a few changes that I'd need to make to get our usage backwards compatible. SigC::slot() now takes references only. Older versions accept both references and pointers So we'd just need to change a few things i.e d_.showAboutlyx.connect(SigC::slot(this, &ControlAboutlyx::show)); d_.showAboutlyx.connect(SigC::slot(*this, &ControlAboutlyx::show)); Plus there's the #include problem as they've removed signal_system.h and you now need to include slot.h or signal.h depending on what you're using. this can be solved with an intermediate file containing #ifdef s. >| - GUII > >but this will decide how easy that is going to be.
