So if I go into QtDesigner and build a UI, it'll be saved as a .ui file. How can I make this as a python file or use this in python?
This question is related to

user-interface
qt
pyqt
qt-designer
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.
in pyqt5 to convert from a ui file to .py file
pyuic5.exe youruifile.ui -o outputpyfile.py -x
In order to compile .ui files to .py files, I did:
python pyuic.py form1.ui > form1.py
Att.
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_())
You need to generate a python file from your ui file with the pyuic tool (site-packages\pyqt4\bin)
pyuic form1.ui > form1.py
with pyqt4
pyuic4.bat form1.ui > form1.py
Then you can import the form1 into your script.
you can compile the ui files like this
pyuic4 -x helloworld.ui -o helloworld.py
The cleaner way in my opinion is to first export to .py as aforementioned:
pyuic4 foo.ui > 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.
(November 2020) This worked for me (UBUNTU 20.04):
pyuic5 /home/someuser/Documents/untitled.ui > /home/someuser/Documents/untitled.py
Using Anaconda3 (September 2018) and QT designer 5.9.5. In QT designer, save your file as ui. Open Anaconda prompt. Search for your file: cd C:.... (copy/paste the access path of your file). Then write: pyuic5 -x helloworld.ui -o helloworld.py (helloworld = name of your file). Enter. Launch Spyder. Open your file .py.
I found this article very helpful.

I'll briefly describe the actions to create and change .ui file to .py file, taken from that article.
The file is created and saved, now we will Generate the Python code from it using pyuic!
Hope this helps someone.
You can convert your .ui files to an executable python file using the below command..
pyuic4 -x form1.ui > form1.py
Now you can straightaway execute the python file as
python3(whatever version) form1.py
You can import this file and you can use it.
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_())
