Here's some code snippets from my app (self.ui.list_links is a QListWidget, 
but i think that it would be same with QListView). Note that you should 
reimplement both dragEnterEvent and dragMoveEvent (the letter is not required 
for QLineEdit)

class MyForm(QtGui.QMainWindow):
        def __init__(self, parent=None):
                QtGui.QWidget.__init__(self, parent)
                self.ui.list_links.__class__.dragEnterEvent = 
self.DragEnterEvent
                self.ui.list_links.__class__.dragMoveEvent = 
self.DragEnterEvent
                self.ui.list_links.__class__.dropEvent = self.drop
		self.ui.list_links.setAcceptDrops(1)
	

        def DragEnterEvent(self, event):
                if event.mimeData().hasFormat("text/plain"):
                        event.accept()
                else:
                        event.ignore()

        def drop(self, event):
                link=event.mimeData().text()
                print link
