I know that there is some PPA for Qt5. I did not try it because KDE4 plugins (addressbook) is incompatible with Qt5. This is something which I need... So Qt5 version of Trojita is not for my KDE4 desktop. It is step back. > What you won't be able to do is upgrading Trojita to a newer version while > not installing Qt5 on your system.

On the other hand, it is not possible to write needed C++ macros which wrap non existent Qt5 calls into Qt4? Compile-time signal-slot connection check is not possible, but it is not possible at least to write some compatibility macro for Qt4 which just do same functionality without compile-time checks? If you would agree with such change I can try to do something... > Cheers, > Jan > > [1] https://launchpad.net/~beineri > -- Pali Rohár pali.ro...@gmail.com
