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

Using the font dialog

In this recipe, we will learn to use a font dialog to apply different fonts and styles to the selected text.

We will make use of a Text Edit widget and a Push Button widget in this application. The push button, when clicked, will open the font dialog. The font and style selected from the font dialog will be applied to the text written in the Text Edit widget.

In this recipe, we will be making use of the QFontDialog class, which displays a Dialog widget meant for selecting a font.

How to do it...

Let's create a new application based on the Dialog without Buttons template by performing the following steps:

  1. Drag and drop a Push Button and a Text Edit widget onto the form.
  2. Set the text property of the Push Button...
