Thanks, this looks like what I need. One concern, though.
QItemEditorFactory::registerEditor() takes a QVariant::Type to designate
the type of data edited. QVariant::Type is restricted to a few
predefined Qt classes. Will I run into a brick wall if I try to define
an editor for my own custom class (e.g. Vector<3>, a class for
three-dimensional vectors (in the mathematical sense))?

Greets,
