Help with Python/PyQt4 Programming, please?

[alefterasm]

Hey! I'm running into some issues with a program I'm developing for a nonprofit. I've starred out the sensitive stuff, but here it is. Any chance you could tell me where its going bad?


import sys
from PyQt4.Qt import *
from buspass import BuspassUi


class BusPassProgram(QApplication):

def __init__(self, args):

QApplication.__init__(self,args)
self.buspass = Buspass(None)
print self
self.setMainWidget(self.buspass)
self.buspass.show()
self.exec_loop()

class Buspass(BuspassUi):

def __init__(self, parent):

BuspassUi.__init__(self, parent)


self._connectSlots()

def _connectSlots(self):
self.connect(self.save, SIGNAL("clicked()"), self._slotSaveClicked)
self.connect(self.exit, SIGNAL("clicked()"), self._slotExitClicked)

def _slotSaveClicked(self):

db = QSqlDatabase.addDatabase("QMYSQL")
db.setHostName("localhost")
db.setDatabaseName("*****")
db.setUserName("*****")
db.setPassword("*****")
db.open()

personu = self.person.text()
idnumberu = self.idnumber.text()
dateu = date.today()
userinfofile = open("userinfo.txt")
userinfo = userinfofile.readline()

q = QSqlQuery()
q.prepare("INSERT INTO ***** (name, dateissued , buspassID, user)"
"VALUES (personu, dateu, idnumberu, userinfo")
q.exec_()

def _slotExitClicked():

self.quit()


if __name__ == "__main__":

app = BusPassProgram(sys.argv)

Aaaand..
Here's the errors produced.

Traceback (most recent call last):
File "C:\Documents and Settings\Administrator\Desktop\Project\buspassprog ram.py", line 60, in <module>
app = BusPassProgram(sys.argv)
File "C:\Documents and Settings\Administrator\Desktop\Project\buspassprog ram.py", line 14, in __init__
self.buspass = Buspass(None)
File "C:\Documents and Settings\Administrator\Desktop\Project\buspassprog ram.py", line 27, in __init__
self._connectSlots()
File "C:\Documents and Settings\Administrator\Desktop\Project\buspassprog ram.py", line 30, in _connectSlots
self.connect(self.save, SIGNAL("clicked()"), self._slotSaveClicked)
AttributeError: 'Buspass' object has no attribute 'connect'


I would really appreciate your help with this, thanks!

This python code is impossible to read, because all tabs have been removed. Can you edit the post so that the code is enclosed by code tags?

As for your problem, is looks like the problem is with a third-party library (buspass) that you import. The base class does not have a connect method. Most likely, this buspass thing is not a Qt-based library... am I right? If so, it doesn't have slots and signals for you to connect. You can only use slots and signals in a class that derives from a Qt4 base class.

Thank you for your reply! I've fixed the post, as you suggested. How can I go about connecting the slots, then, if not using that method? That's what I find in all of the examples..

Thank you,
