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.

Building your own QTcpServer

Everything is ready to read and write in our sockets. We still need a server to orchestrate all these instances. To do so, we will develop a modified version of the MandelbrotCalculator class, which was covered in Chapter 9, Keeping Your Sanity with Multithreading.

The idea is to respect the same interface, in order to keep MandelbrotWidget oblivious to the fact that the Mandelbrot picture-generation is deported on different processes/machines.

The main difference between the old MandelbrotCalculator and the new one is that we replaced the QThreadPool class with QTcpServer. The MandelbrotCalculator class now only has the responsibility to dispatch JobRequests to Workers and aggregate the results. It will no longer interact with a QThreadPool class.

Create a new C++ class named MandelbrotCalculator.cpp and update MandelbrotCalculator.h to match this...
