AFAIK KParts::Plugins can have widgets, they just don't have to.
And again AFAIK, you don't have to use either MIME type or document with=20
kparts.

Actually I know that above things work, because we (as in developers of=20
Kmud) use kparts and plugins that way :)
(using KTraders to query and load them)

We subclassed KParts::KPart to get a customized Part with additonal=20
interface
(see lib/kmudpart.h in kmud2 sources)

You can query for services implementing your own ServiceType.
(see kmud/kmudcore.cpp method loadPart in kmud2 sources for loading=20
KmudParts and parts/mapper/cmapmanager.cpp method initPlugins for loading=
=20
plugins which can use widgets)
