Python GUI Programming - A Complete Reference Guide

By: Alan D. Moore, B. M. Harwani

Overview of this book

A responsive graphical user interface (GUI) helps you interact with your application, improves user experience, and enhances the efficiency of your applications. With Python, you’ll have access to elaborate GUI frameworks that you can use to build interactive GUIs that stand apart from the rest. This Learning Path begins by introducing you to Tkinter and PyQt, before guiding you through the application development process. As you expand your GUI by adding more widgets, you'll work with networks, databases, and graphical libraries that enhance its functionality. You'll also learn how to connect to external databases and network resources, test your code, and maximize performance using asynchronous programming. In later chapters, you'll understand how to use the cross-platform features of Tkinter and Qt5 to maintain compatibility across platforms. You’ll be able to mimic the platform-native look and feel, and build executables for deployment across popular computing platforms. By the end of this Learning Path, you'll have the skills and confidence to design and build high-end GUI applications that can solve real-world problems. This Learning Path includes content from the following Packt products: Python GUI Programming with Tkinter by Alan D. Moore Qt5 Python GUI Programming Cookbook by B. M. Harwani

Making a bouncing ball

In this recipe, you will make a bouncing ball; when clicking a button, a ball falls towards the ground and on touching the ground, it bounces back to the top. In this recipe, you will understand how a basic animation is applied on an object. This recipe will consist of a push button and a ball, and when the push button is pressed, the ball will start animating towards the ground.

How to do it...

To make a ball appear to be bouncing, we need to make it first animate towards the ground, and then from the ground up to the sky. To do so, we will be invoking the setKeyValueAt method of the QPropertyAnimation class three times. The first and second calls to the setKeyValueAt method will make the ball...
