Overview of this book

Qt 5.11 is an app development framework that provides a great user experience and develops full capability applications with Qt Widgets, QML, and even Qt 3D. Whether you're building GUI prototypes or fully-fledged cross-platform GUI applications with a native look and feel, Mastering Qt 5 is your fastest, easiest, and most powerful solution. This book addresses various challenges and teaches you to successfully develop cross-platform applications using the Qt framework, with the help of well-organized projects. Working through this book, you will gain a better understanding of the Qt framework, as well as the tools required to resolve serious issues, such as linking, debugging, and multithreading. You'll start off your journey by discovering the new Qt 5.11 features, soon followed by exploring different platforms and learning to tame them. In addition to this, you'll interact with a gamepad using Qt Gamepad. Each chapter is a logical step for you to complete in order to master Qt. By the end of this book, you'll have created an application that has been tested and is ready to be shipped.

Architecturing an IPC project

The Mandelbrot picture generator from Chapter 9, Keeping Your Sanity with Multithreading, uses all the cores of your computer to speed up the computing. This time, we want to use all the cores of all of your computers! The first thing is to choose an appropriated IPC technique. For this project example, we want to establish communication between several clients acting as workers to a server running the main application. The TCP/IP sockets allow a one-to-many communication. Moreover, this IPC method is not bound to a single computer and can operate through a network on multiple computers. This project example uses sockets by implementing a multithreaded TCP server.

The following diagram describes the architecture:

Let's talk about the global role of each actor:
