How to generate Python code of GUI created under Taurusdesigner or Qt?

First of all let me tell you that I am new to Qt and also to Python.

I am using Qt(Taurusdesigner) to create my GUIs. After starting Qt(Taurusdesigner), I generate my python code for that particular GUI using:

taurusuic4 -x -o file.py file.ui
or
pyuic4 -x -o file.py file.ui

After executing this command on command line I am able to generate python file, but the auto generated classes looks like:

class MainWindow(object):
    def setupUi(self, MainWindow):

Where as when I am searching for any help on Google I find class written like:

class MainWindow(QtGui.QMainWindow):
    def __init__(self, parent=None):

What would I do to generate 2nd type of class file using Qt(Taurusdesigner)??

Why there is a syntax difference in my class and class which are written for help on internet. Please Help regarding this. Thanks in advance.

The ui module generated by taurusuic4/pyuic4 should be imported into your main application. You do not need to use the -x option, and obviously you should choose a better module name than "file":

taurusuic4 -o mainwindow.py file.ui

Your main application module should look something like this:

from PyQt4.QtGui import QMainWindow
from mainwindow import Ui_MainWindow

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setupUi(self)
        self.pushButton.clicked.connect(self.handleButton)

    def handleButton(self):
        print('Hello World!')

This approach means that all the widgets from Qt(Taurus) Designer end up as attributes of the MainWindow class. Another approach is to have the ui elements within a separate namespace:

class MainWindow(QMainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        self.ui.pushButton.clicked.connect(self.handleButton)

setupUI and __init__ are two methods of the class MainWindow. For one class, there can be any number of method and you can put them in whatever order you like.

There is always an __init__ method, it's called a constructor. This method is called when you create an object (for example when you do myWindow=MainWindow()). It's usually put at the beginning because it'll be call first. Specifically for QT, you have to call the parent's constructor with super.

setupUI is the method created by your designer, to take care of layout and such. It should be called in the constructor.

Your code should look like:

class MainWindow(object):
    def setupUi(self, MainWindow):
        #code made by the designer

    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setupUi(self)
        #some code

   def another_method(self):
        #some more code
