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

Finding out the distance between two locations

In this recipe, you will learn how to find out the distance in kilometers between the two locations entered by the user. The recipe will simply prompt the user to enter two locations, followed by clicking the Find Distance button, and the distance between the two will be displayed.

How to do it…

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

  1. Add four QLabel, two QLineEdit, and a QPushButton widget to the form by dragging and dropping four Label, two Line Edit, and a Push Button widget onto the form.
  2. Set the text property of the first Label widget to Find out the distance between two locations, that of the second...
