Yes but that only works for "plain" QListViewItems, not for any fancy
custom items, so I guess it's rather useless.

I was annoyed by QListView's inability to move items when I made my
generic DND-capable listview for KSysV (kdeadmin/ksysv/kndraglist.{h,cpp}
and kdeadmin/ksysv/ksvdraglist.{h,cpp}), but I'm now convinced that
overriding QListViewItem::key is the correct solution for most
situations.

Although a moveToJustBelow (QListViewItem*) - or something similar - would
be nice, too.

Peter
