using QFtp class in PyQT

[Kim]

Hi everybody,
I tried to write simple FTP program using PyQt version 3.11. The
document say that QFtp has been implemented, but i keep getting error
message from my simple program :

My Program:

from qt import *
from qtnetwork import *

def gotSignalStart( *arg):
print "start ",arg

def gotSignalState( *arg):
print "state ",arg

def gotListInfo(*ar g):
print "List info ",arg

def doFTP():
fh = QFtp()
QObject.connect (fh,SIGNAL("sta rt()"),gotSigna lStart);
QObject.connect (fh,SIGNAL("sta teChanged()"),g otSignalState);
QObject.connect (fh,SIGNAL("lis tInfo()"),gotLi stInfo);
fh.connectToHos t("ftp.trolltec h.com")
fh.login()
print fh.state()
if fh.state() != QFtp.Unconnecte d : fh.close()

doFTP();

Error messages:

QObject::connec t: No such signal QFtp::start()
QObject::connec t: (sender name: 'unnamed')
QObject::connec t: (receiver name: 'unnamed')
QObject::connec t: No such signal QFtp::stateChan ged()
QObject::connec t: (sender name: 'unnamed')
QObject::connec t: (receiver name: 'unnamed')
QObject::connec t: No such signal QFtp::listInfo( )
QObject::connec t: (sender name: 'unnamed')
QObject::connec t: (receiver name: 'unnamed')
0
QSocket::writeB lock: Socket is not open


Can anyone help?
Thanks very much
Kim

You must give the full (C++) signature of the signal, eg...

SIGNAL("listInf o(const QUrlInfo &)")

QFtp is asynchronous. You need an event loop to make sure things actually
happen.
