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.

Summary

IPC is a fundamental mechanism in computer science. In this chapter, you learned the various techniques offered by Qt to do IPC and how to create an application that uses sockets to interact, send, and receive commands. You took the original mandelbrot-threadpool application to the next level by enabling it to generate pictures on a cluster of machines.

Adding IPC on top of a multithreaded application brings some issues. You have many more possible bottlenecks, chances of leaking memory, and having an inefficient calculation. Qt provides multiple mechanisms to do IPC. Since Qt 5.7, the addition of transactions that makes the serialization/deserialization part much easier.

In the next chapter, you will discover the Qt Multimedia framework and how to save and load a C++ object from a file. The project example will be a virtual drum machine. You will be able to save and load...
