[PyQt] Drag & Drop with QTreeWidget

It worked nicely up to the sorting part.
And if th euser sorts the data himself, then eveything is ok.
It's just when I try to implement default sorting that that fails.
Maybe I can pick up on a signal telling that sorting is in progress to override this behaviour in the rowsInserted function...

actually, i now think my approach was too crude. the trouble with using
rowsInserted is that it is called every time items are added or moved
what is really needed is a way to add special handling only for dropped
items. unfortunately, there does not appear to be an obvious way to
detect what items were dropped and where. so i think the only reliable
way to get the behaviour you want is to reimplement qtreewidget's drop
event handling (which is probably doable, but not easy).
