Hello i have made a small test using qftp, but i make some error:

class Form(QWidget, Ui_Form):
    """
    Class documentation goes here.
    """
    def __init__(self, parent = None):
        """
        Constructor
        """
        super(Form, self). __init__(parent)
        self.connessione = QtNetwork.QFtp()
        self.connect(self.connessione, QtCore.SIGNAL("stateChanged()"), self.
risultato_connessione)
        QWidget.__init__(self, parent)
        self.setupUi(self)
    
    @pyqtSignature("")
    def on_pushButton_clicked(self):
       self.connetto()
        
    def connetto(self):
        luca = self.connessione.connectToHost('host', 21)
        
    
    def risultato_connessione(self):
        print 'sig received'

so if i understand right when the state of the connection change the signal 
"stateChanged()" is emitted and it is emitted also for HostLookup but i never 
get this signal why?

Thanks

Luca
