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

Drawing text in a desired font and size

In this recipe, we will learn to draw text in a specific font and at a specific font size. Four widgets will be required in this recipe such as Text Edit, List Widget, Combo Box, and Push Button. The Text Edit widget will be used to enter the text that the user wants to display in the desired font and size. The List Widget box will display different font names that the user can select from. The Combo Box widget will display font sizes that the user can select to define the size of the text. The Push Button widget will initiate the action, that is, the text entered in the Text Edit widget will be displayed in the chosen font and size on clicking the push button.
