Stefan, thanks for your interest :)
I propose copying (branching) the code as temporary solution.
I think about having the lib as Qt-only and putting it somewhere
outside of koffice.
Until then I guess we could exchange patches. Doing that please also
alter the cmake file, in particular change the name to something like
kopropertykolf or so. Later you shall be able to change to shared
qt-only library and packagers would not notice anything except just a
need for adding additional dependency.

Please not that your special editors and types could be implemented
outside of koptoperty in factories delivered by plugins. This could
avoid many internal modifications.

Own property set "Set" class and "Property" item is used.
You'll be able to map your Qt properties to these easily. In fact I do
that in Kexi Forms but since other uses of KoProperty are not based on
Qt properties, this code is not shared.
I am open to have it in KoProperty though.

It's possible to add of course and I am open for supporting you.
Reasonable medium where we can share the docs on how to use the
framework is probably techbase. How do you like it?
