[PyQt] Invoking user interface design

[12203276]

Hey everyone, I am currently teaching myself to use PyQt4 and I have one problem that I do not know how to fix.

When I design my interface in PyQt4 and convert it to py and import it into my Python script nothing seems to happen. 

I got the code from a textbook, Please see code below:

import sys
from fairCalculator import *
from PyQt4.QtGui import *

class MyForm(QtGui.QDialog):
    def ___init___(self, parent = None):
        QtGui.QWidget.___init___(self, parent)
        self.ui = Ui_Dialog()
        self.ui.setupUi(self)
        timer = QtCore.QTimer(self)
        timer.timeout.connect(self.showlcd)
        timer.start(1000)
        self.showlcd()
        
        QtGui.QObject.connect(self.ui.buttonOne, QtCore.SIGNAL('clicked()'), self.buttonOne)

    def buttonOne(self):
        self.ui.label.setText("Please pay R 10.00 for Class One.")

    def showlcd(self):
        time = QtCore.QTime.currentTime()
        text = time.toString('hh:mm')
        self.ui.lcdNumber.display(text)

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = MyForm()
    myapp.show()
    sys.exit(app.exec_())

When I press F5 to run the program I do not get any errors but the interface do not show. A window named Pythonw but nothing appears on the screen it's just a blank window. Now I have tried to re-install the programs I even tried different versions, I even went so far to test it on three different computers and the result is the same.

Any assistance will be appreciated

I am using Python version 3.4 and PyQt4 version 4.11.4

you are suposed to put the code in the code box, not around it
