That's because root.parent() is an invalid index, and your code 
explicitly rejects such drops. Try changing the else branch to 
explicitly test for indexAt(event->pos()) == root and accept such events.

What's the idea behind "reject drops to indexes without a parent"? Looks 
like you're also disabling drops to empty space.

Cheers,
Jan
