[Development] Qt LTS & C++11 plans (CopperSpice)

[Bernhard]

Unfortunately adding signals of the template’s type is exactly what I would have needed several times. In that case there is no clean solution. I once added QVariant based signals as a workaround but that was ridiculous. In modern times having powerful C++ generic programming features it is a shame that QObject doesn’t support this. IMHO this is one of the features (like C++11) that need to be introduced in Qt as fast as possible if it should not appear old-fashioned soon.

Wow. I would (almost) kill for having that feature in Qt!
 


You can work around it quite easily. What doesn’t work is adding new signals / slots inside a template class. So just add a base class declaring these signals/slots, and make your template class inherits from it.

Unless you wan’t to use the template class as signal/slots arguments, this works fine.
