Rebranding to QtCt?

[ilya-fedin]

It's really inconvenient to use Qt5&Qt6 apps together since it's impossible to set multiple values to QT_QPA_PLATFORMTHEME. Since qt5ct & qt6ct almost identical, why not to support both Qt versions in one codebase with support to build both variants? That way, it would be possible to set QT_QPA_PLATFORMTHEME=qtct and have all Qt applications styled.

This was one of the first questions which came to my mind as I learned yesterday about qtXct: how do I handle a system with a mixture of qt5 and qt6 applications?
An alternative would be to introduce version specific environment variables like QT6_QPA_PLATFORMTHEME, but this becomes more difficult to maintain with each new version.

You can try to use "-platformtheme qt6ct" argument for your qt6 app. This is not very convenient, but may be useful.
