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

Displaying a 2D graphical image

In this recipe, you will learn to display a 2D graphical image. We assume that you have a graphical image by the name scene.jpg on your machine, and you will learn how it is displayed on the form. The focus of this recipe is to understand how the Graphics View widget is used to display an image.

How to do it...

The procedure for displaying graphics is very simple. You first need to create an object of QGraphicsScene, which in turn makes use of the QGraphicsView class to show its contents. Graphical items, including images, are then added to the QGraphicsScene class by invoking the addItem method of the QGraphicsScene class. Here are the steps to display a 2D graphical image on the screen:
