title: pyqt dropEvent will not fire
body: <p>I am trying to drag a list item onto another list. The dragEnterEvent fires just fine, I do e.accept(), however the dropEvent never fires. Here's the code:</p>
  
  <pre><code>class LocalList(QtGui.QListWidget):
      def __init__(self, parent):
          super(LocalList, self).__init__(parent)
          self.parent = parent
          self.setDragEnabled(True)
  
      def mouseMoveEvent(self, e):
          mimeData = QtCore.QMimeData()
          mimeData.setText(self.currentItem().text())
          drag = QtGui.QDrag(self)
          drag.setMimeData(mimeData)
          dropAction = drag.exec_()
  
  class RemoteList(QtGui.QListWidget):
      def __init__(self, parent):
          super(RemoteList, self).__init__(parent)
          self.parent = parent
          self.setAcceptDrops(True)
  
      def dragEnterEvent(self, e):
          print "MimeText: " + e.mimeData().text()
          e.accept()
  
      def dropEvent(self, e):
          print "DROPPED"
          print self.parent.localdir + "/" + e.mimeData().text()
          e.accept()
  </code></pre>
  
  <p>To clarify, I'm dragging from LocalList to RemoteList. The mousMoveEvent is being fired just fine, because the mimeData().text() prints out just fine in RemoteList's dragEnterEvent. I don't think it's accepting right though, because dropEvent is never fired, and when I'm hovering over the RemoteList it doesn't have the "drop here" icon.</p>
