Introduction

This tab has code inspired by:

Python and PyQt: Building a GUI Desktop Calculator – Real Python https://realpython.com/python-pyqt-gui-calculator/

The Real Python link is a nice introduction to the whole process of building a simple but complete QT application.

It also includes information on installing QT.

Our code has several different layouts similar to the ones presented in the tutorial. We use our own base tab widget instead of a main window so we can have all the code in one tab rather than separate files and applications. For best results we recommend that you do read the material on the Real Python Site.

See the code in your IDE or pyqt_by_example/tabs/real_python/tab_q_real_python_1.py at main · russ-hensel/pyqt_by_example https://github.com/russ-hensel/pyqt_by_example/blob/main/tabs/real_python/tab_q_real_python_1.py

ScreenShot

Keeping screenshots up to date is a task that still eludes us, Running the application is the best way to see the window.
