Once you build your GUI in the Designer (for Qt5), you can convert the UI into  Python source code
python -m PyQt5.uic.pyuic -x [FILENAME].ui -o [FILENAME].py
 
python3 -m PyQt5.uic.pyuic -x qt5designtest.ui -o qt5designer.py

Then you can run with your Python 3 interpreter:
python3 qt5designer.py

Rapid WYSWYG book on Qt Designer with Python

Learning this tool will most likely involve a book to work but it get messy if you are using Qt 4 vs 5 vs Python 2 or 3. That alone will make abandon this idea.

"Switching" to Python. GUIs vs. Web apps from Python

Qt Creator has had support for python since version 2.8. The latest version is 3.3.

As you mention, with PyQt, licensing for commercial development ins’t free.

One alternative you don’t metnion is PyOtherside which is a Qt 5/QML plugin that allows you to (mostly) use Python for your backend code instead of Javascript. While Qt Creator does havea QML designer, you may find that the language is declarative enough that you prefer writing it by hand. I, for instance, use my qmlive tool when creating QML apps*, which allows me to do live coding. If you need something more native looking, QML does have Qt Quick Controls which provides native widgets for Windows, Linux, Mac, Android, and (I think) iOS). One final benefit of going the QML route is that in practice, it’s language independent. For instance, the little demo in the video started out with a javascript backend, then I ported it to Haskell, though I could have easily done the same with Python.

  • The tool currently doesn’t work with using QML Controls and I haven’t updated it since creating it since I primarily do web development at the moment.

All the tools you need are included in Ubuntu repositories. You must install the package qtcreator, which has an integrated QtDesigner, and the package pyqt5-dev-tools, which provides pyuic5, a utility that generates Python code from .ui files.

sudo apt-get install qtcreator pyqt5-dev-tools

To convert to Python use:

pyuic4 editorFrame.ui -o editorFrame.py

You may need to install utility so use:

apt-get install pyqt4-dev-tools

Running Qt Designer with Python pyqtgraph

Running Qt Designer with Python pyqtgraph

Here are more notes on how to get this powerful combo running with a GUI builder including a powerful plot. This can be done

 

Running Qt Designer
When you pyqt, it is installed as well but you will find it in a strange spot

find /Users -name Designer*

found in /Users/quantlabsnet/Qt/5.5/clang_64/bin/Designer.app

Convert .ui file to .py with
pyuic4 -x testDesigner.ui -o testDesigner.py

To use pyqtgraph ‘element’, follow
https://groups.google.com/forum/#!msg/pyqtgraph/31cqr43cvCA/K8aCYomRrBYJ
and another approach
https://github.com/pyqtgraph/pyqtgraph/commit/4e9e75817fb0d2b5f6880278857621af30d7d0f1

The VideoSpeedTest and ScatterPlotSpeedTest examples in pyqtgraph both use .ui files that were compiled using the tools/rebuildUi.py script (which just calls pyuic4

Note that there is also exampleLoaderTemplate.ui and exampleLoaderTemplate_pyside.py
but pyside package is needed

pip install -U PySide

You may need cmake: brew install cmake
