I found this article very helpful    http   talk maemo org archive index php t-43663 html  I ll briefly describe the actions to create and change  ui file to  py file  taken from that article    Start Qt Designer from your start menu  From  New Form  window  create  Main Window  From  Display Widgets  towards the bottom of your  Widget Box Menu  on the left hand side add a  Label Widget    Click Drag and Drop  Double click on the newly added Label Widget to change its name to  Hello World  at this point you can use Control   R hotkey to see how it will look  Add buttons or text or other widgets by drag and drop if you want  Now save your form   File- Save As-   Hello World ui   Control   S  will also bring up the  Save As  option   Keep note of the directory where you saved your  Hello World   ui file   I saved mine in  C   for convenience    The file is created and saved  now we will Generate the Python code from it using pyuic    From your start menu open a command window  Now  cd  into the directory where you saved your  Hello World ui  For me i just had to   cd   and was at my  C    prompt  where my  Hello World ui  was saved to  When you get to the directory where your file is stored type the following  pyuic4 -x helloworld ui -o helloworld py Congratulations   You now have a python Qt4 GUI application    Double click your helloworld py file to run it    I use pyscripter and upon double click it opens in pyscripter  then i  run  the file from there    Hope this helps someone

You can also use uic in PyQt5 with the following code   from PyQt5 import uic  QtWidgets import sys  class Ui QtWidgets QDialog       def   init   self           super Ui  self    init             uic loadUi  SomeUi ui   self          self show    if   name         main         app   QtWidgets QApplication sys argv      window   Ui       sys exit app exec

Another way to use  ui in your code is   from PyQt4 import QtCore  QtGui  uic class MyWidget QtGui QWidget               somewhere in constructor      uic loadUi  MyWidget ui   self    both approaches are good  Do not forget  that if you use Qt resource files  extremely useful  for icons and so on  you must compile it too   pyrcc4 exe -o ui images rc py ui images images qrc   Note  when uic compiles interface  it adds  import images rc  at the end of  py file  so you must compile resources into the file with this name  or rename it in generated code

Combining Max s answer and Shriramana Sharma s mailing list post  I built a small working example for loading a mywindow ui file containing a QMainWindow  so just choose to create a Main Window in Qt Designer s File-New dialog    This is the code that loads it   import sys from PyQt4 import QtGui  uic  class MyWindow QtGui QMainWindow       def   init   self           super MyWindow  self    init             uic loadUi  mywindow ui   self          self show    if   name         main         app   QtGui QApplication sys argv      window   MyWindow       sys exit app exec

The cleaner way in my opinion is to first export to  py as aforementioned    pyuic4 foo ui  gt  foo py   And then use it inside your code  e g main py   like   from foo import Ui MyWindow   class MyWindow QtGui QDialog       def   init   self           super MyWindow  self    init              self ui   Ui MyWindow           self ui setupUi self             go on setting up your handlers like            self ui okButton clicked connect function name            etc     def main        app   QtGui QApplication sys argv      w   MyWindow       w show       sys exit app exec      if   name         main         main     This way gives the ability to other people who don t use qt-designer to read the code  and also keeps your functionality code outside foo py that could be overwritten by designer  You just reference ui through MyWindow class as seen above
