This is what I use:
export QT_QPA_PLATFORMTHEME=kde

and  you need the integration plugin installed. It used to be part of
Frameworks (frameworksintegration), it will be part of Plasma (but hopefully
still usable without).
The idea is that other desktop environments will provide their own integration
plugin, but I agree that there are use cases where this won't happen (run
application as root, run as another user, minor Qt-based desktop environments,
etc). That said, I'm just an user regarding Plasma stuff.
