[PyQt] Help to run my sample PyQt program

[John R]

Hello All,

I have created a UI file in Qtcreator and converted to python using pyuic.
after conversion I added following code blocks into this new python file
for PySide execution I had added number of widgets like buttons, radio
buttons, textboxes etc. and it run in Qt creator fine but after pyuic
conversion I could see only plain blank screen!!, could anyone please tell
me, where I have made wrong code. I have tried to run in Tkinter and
QtCreator (via Tools --> External --> Python ---> RunPy), both Tkinter and
Qt creator showing output only blank GUI

*Please note the modified code blocks*


*Code Block Added 1:*

import sys
from PySide import QtCore, QtGui


*Code Block Added 2:*

class ControlMainWindow(QtGui.QMainWindow):
 def init(self, parent=None):
     super(ControlMainWindow, self).init(parent)
     self.ui = Ui_MainWindow()
     self.ui.setupUi(self)

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    mySW = ControlMainWindow()
    mySW.show()
    sys.exit(app.exec_())




*Full code is below*
