File Read/Write | Notepad App w/ Python & Qt (2022) | EP4

In the last episode of the Notepad App w/ Python & Qt series, we implemented the file dialog using QML. Yet, the actual file operations have not been implemented. In this episode, I demonstrated the actual file read/write using Python.

File operations in Python is an easy task. The main focus of this episode is the communication between the Python and QML. The Qt slot feature was used for the signal and data transfer between the two languages. It allows data to be passed between the two contexts, which together makes a powerful application.

This series is created as an example of building a GUI application using Python, as well as building a desktop application which will work on Linux and Windows. Follow this series and you will learn how to make a GUI app using Python and the Qt framework.
