Can't start designed pyQt application

问题

I have just designed my application inside pyQt Designer 5, generated my main.ui to main.py and my assets.qrc to assets_rc.py. No errors, when I now run main.py from my terminal nothing happends. Have I missed a step? Am I supposed to edit my main.py file now?

Cheers!

Python 3.3.0 pyQT 5

This is for PyQt4, but should be the same for PyQt5.

Let's say your ui is called "mainwindow.ui". Compile this with pyuic4 into "mainWindowUi.py" (or whatever, just stick to the name).

Now create a file "mainWindow.py" with more or less this content:

from PyQt4 import QtGui
from mainWindowUi import Ui_MainWindow #same name as appears in mainWindowUi.py

class MainWindow (QtGui.QMainWindow): #Or wherever you are inheriting from
    def __init__ (self, parent = None):
        super (MainWindow, self).__init__ ()
        self.ui = Ui_MainWindow () #same name as appears in mainWindowUi.py
        self.ui.setupUi (self)

    #implement slots and signals and other funny things

Now create a file "program.py" with more or less this content:

#! /usr/bin/python3.3

import sys
from PyQt4 import QtGui
from mainWindow import MainWindow

def main():
    app = QtGui.QApplication (sys.argv)
    m = MainWindow ()
    m.show ()
    sys.exit (app.exec_ () )


if __name__ == '__main__':
    main ()

Run the program.py file. This is more or less the skeleton of a Qt application.
