Hello Marek, First of all, you are probably better of reposting this to the developer list: https://mail.kde.org/mailman/listinfo/kde-devel
But since I am replying already :) On Monday, 2014-02-03, 15:16:49, Marek Kochanowicz wrote: > Hello, > > I have to admit, that I have some problems understanding the QtMetaTypes > system.

In such a case the easiest case might be to store an identifier of some sort and let the drop recipient use that to do an look up for the actual object. In either case this is most likely not related to the Qt meta type system at all. Cheers, Kevin -- Kevin Krammer, KDE developer, xdg-utils developer KDE user support, developer mentoring
