title: How to tell where an item was dropped in qlistview?
body: <p>I have a custom QListView:</p>
  
  <pre><code>from PyQt4.QtCore import *
  from PyQt4.QtGui import *
  
  from Diagnostics import Trace2 #writes to log file
  import traceback
  
  class ListOrderView(QListView):
  
      itemMoved = pyqtSignal(int, int, QStandardItem) # Old index, new index, item 
  
      def __init__(self, parent=None):
          try:
              super(ListOrderView, self).__init__(parent)

              self.setDragEnabled(True)

              self.setDefaultDropAction(Qt.MoveAction)
  
              self.setEditTriggers(QAbstractItemView.NoEditTriggers)
              self.setSelectionBehavior(QAbstractItemView.SelectRows)
              self.setSelectionMode(QAbstractItemView.SingleSelection)
  
              self.dragItem = None
              self.dragRow = None
  
              self.indexesMoved.connect(self.onIndexesMoved)
              #self.installEventFilter(self)
          except:
              Trace2.WriteLine(str(traceback.format_exc()))
  
      def onIndexesMoved(self, indexes):
          Trace2.WriteLine("indexes were moved")
  
      def dropEvent(self, event): 
          try:
              super(ListOrderView, self).dropEvent(event) 
  
              self.selectionModel().setCurrentIndex(self.model().indexFromItem(self.dragItem), QItemSelectionModel.SelectCurrent)
              Trace2.WriteLine("[LISTVIEW] item dropped")
              Trace2.WriteLine("[LISTVIEW] current index is %d" %self.selectionModel().currentIndex().row())
              Trace2.WriteLine("[LISTVIEW] current selection is %d" %self.selectionModel().selection().indexes()[0].row())
  
              self.itemMoved.emit(self.dragRow, self.row(self.dragItem), self.dragItem)
              self.dragItem = None
          except:
              Trace2.WriteLine(str(traceback.format_exc()))
  
      def startDrag(self, supportedActions): 
          try:
              self.dragItem = self.currentItem() 
              self.dragRow = self.row(self.dragItem)

          return item
  
      def row(self, item):
          #index = self.model().indexFromItem(item)
          index = self.selectedIndexes()[0]
          row = index.row()
  
          #Trace2.WriteLine("[LISTVIEW] row = %d" %row)

  </code></pre>
  
  <p>And I really need to know where the item was dropped after a drag and drop operation so other things can be properly updated (I'm trying to put drag and drop into something never designed for it, big app, not my design). The selection model's current index and selection don't follow the dropped item, they stay behind effectively selecting a new item and screwing things up. Is there a way to make them move with the dropped item? The signal indexesMoved seems exactly like what I want, but it never fires. Am I using it wrong? Is there a different/better way?</p>
