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.

Laying down the foundations with an SDK

The first step is to implement the classes that will be shared between our application and the workers. To do so, we are going to rely on a custom SDK. If you need to refresh your memory about this technique, take a look at Chapter 8, Animations It's Alive, Alive!.

As a reminder, here is the diagram that describes the SDK:

Let's look at the job of each of these components:

  • The Message component encapsulates a piece of information that is exchanged between the application and the worker.
  • The JobRequest component contains the necessary information to dispatch a proper job to a worker.
  • The JobResult component contains the result of the Mandelbrot set calculation for a given line.
  • The MessageUtils component contains helper functions to serialize/deserialize data across the TCP socket.
