[PyKDE] Stuck newbie

[Johannes Graumann]

Thanks for your help! The clueless (but ambitious) one is one step further ;0)

Can somebody tell me how to properly connect my 'actionQuit_Ctrl_Q' with a quit signal for the whole Application execution loop?

Thanks for your patience,

Joh

class ElNotes(QtGui.QApplication):
    def __init__(self,args):
      QtGui.QApplication.__init__(self, args)
      self.maindialog = uic.loadUi("ElNotes_GUI.ui")
      self._connectSlots()
      self.maindialog.show()
      self.exec_()
    def _connectSlots(self):
      self.connect(self.maindialog.actionQuit_Ctrl_Q,QtCore.SIGNAL("clicked()"),self.slotQuit_Ctrl_Qclicked())
    def slotQuit_Ctrl_Qclicked(self):
      self.connect(QtCore.SLOT("quit()"))
