[PyQt] Problem with KDialogButtonBox.addButton

[Wolfgang Rohdewald]

Hi,

how can I pass my own python slot to addButton?
 
def slotInsert(self):
  pass

newItem = KGuiItem(QString("&New"), KIcon("document-new"))
self.newButton = self.buttonBox.addButton(newItem, KDialogButtonBox.ActionRole, self, self.slotInsert)

TypeError: KDialogButtonBox.addButton(): arguments did not match any overloaded call:
  overload 1: argument 1 has unexpected type 'KGuiItem'
  overload 2: argument 1 has unexpected type 'KGuiItem'
  overload 3: argument 4 has unexpected type 'instancemethod'
  overload 4: argument 3 has unexpected type 'PlayerList'

This is KDE 4.4 with pyqt4 4.7.0
