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

Exploring Tkinter widgets

When we designed our application, we picked out a widget class that most closely matched each field we needed. These were the Entry, Spinbox, Combobox, Checkbutton, and Text widgets. We also determined that we'd need the Button and LabelFrame widgets to implement the application layout. Before we start writing our class, let's take a look at each of these widgets.

Some of our widgets are in Tkinter, others are in the ttk themed widget set, and a few are in both libraries. We prefer the ttk versions wherever they exist, since they look better across platforms. Pay careful attention to the library from which we import each widget.

The Entry widget

The ttk.Entry widget is a basic, one...
