I don't think of it as sloppy clicks, but as not enough movement to start a
drag. In the mouseMoveEvent handler, I would check that the manhattan
distance over the 5 pixels and only then start the drag. I would also
remove the check of the manhattan distance in the dropEvent handler. Even
if the item is dragged away and then dropped exactly back at the start
position, the operation should be seen as a drag/drop not a click. A click
will occur only if the mouse is pressed and then released without ever
moving more than 5 pixels from the press position.
