I've just updated that test program, and it runs fine:

#!/usr/bin/env python

import os
import sys

from qt import *

class myListViewItem(QListViewItem):

  def __init__(self, parent):
    QListViewItem.__init__(self, parent)

  def slotHook(self):
    print "slotHook"

class frmListView(QListView):
  def __init__(self, parent=None):
    QListView.__init__(self, parent)

    self.addColumn("a", 200)
    self.addColumn("b", 200)

    self.rows=[]
    lvi=myListViewItem(self)

    lvi.setText(0, "xxxxx")
    lvi.setText(1, "yyyyy")
    self.rows.append(lvi)

    self.connect(self, SIGNAL("doubleClicked ( QListViewItem * )")
                     , self.slotOpenFile
                     )

  def slotOpenFile(self, item):
    print item
    self.currentItem().slotHook()

def main():

  qapp=QApplication(sys.argv)
  toplevel=frmListView()
  toplevel.show()
  qapp.connect(qapp, SIGNAL('lastWindowClosed()'), qapp, SLOT('quit()'))
  print qapp.exec_loop()
  
if __name__=="__main__":
  main()

 
                                                                                     
bash-2.03$ python qlsv_sig.py
