A key step in simplifying the use of SplashTool is providing an easy-to-use graphical user interface (GUI). After some research, I decided to implement the GUI using the Qt framework. It offers extensive modern functionalities, platform independence, and direct integration with Python via PyQt5 and PySide2.
GUI programming is completely new to me, so before the actual programming, I need to learn the basics first. For this, I use the website by Martin Fitzpatrick, which provides eBooks, code examples, tutorials, and much more.
