Retrieving text from password field [python][pyqt4]

Question

def welcomeStage (self):        
    self.test = QtGui.QLineEdit (self)
    self.test.move (50, 150)

    QtCore.QObject.connect (self.test, QtCore.SIGNAL ('returnPressed()'), self.passwordStage)

def passwordStage (self):
    self.email = self.test.text()
    self.test.clear()
    self.test.setEchoMode (QtGui.QLineEdit.Password)
    QtCore.QObject.connect (self.test, QtCore.SIGNAL ('returnPressed()'), self.loginStage)

def loginStage (self):
    self.pwd = self.test.text()
    print self.pwd
    if len (self.pwd) < 0:
        welcomeStage ()
        return

Simply put, I am making a login form. The user enters their email, then the text field is cleared and echo mode is set to Password mode. The text() function returns the email fine, but when I call text() after I have changed the echo mode, it returns 0. I've been pouring over the documentation looking for anything regarding the text() function and how it operates when Password mode is on, however I have not found anything. Does anybody know how this is done?

I can't offer a fix for using a QLineEdit, but you can get passwords in a QInputDialog by specifying mode in the getText() method. Like this:

diag = QtGui.QInputDialog
s = None
while s is None:
    qstring, ok = diag.getText(self, QtCore.QString(title), QtCore.QString(text), mode=QtGui.QLineEdit.Password)
    s = str(qstring)
    if ok is False: # user pressed Cancel
        return None
    if s == '':     # user entered nothing
        s = None
return s
