I've checked all implementations listed by 
http://lxr.kde.org/ident?i=KDirOperator. The only changes that access 
KDirOperator::view() and KDirOperator::setView() and need to be adapted are:

- KDE/kdesdk/kate/filebrowser/katefileselector.cpp:
  dir->view()->setSelectionMode(...)

- extragear/graphics/kuickshow/src/filewidget.cpp:
  view()->items()->getFirst();

That's really less and indicates that this interface is used very rarely. And 
even if this interface is used, I think it absolutely makes more sense for 
KDE4 application developers to be able to set any kind of QAbstractItemView 
instead of the need of implementing the KFileView interface...

Best regards,
Peter
