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.

Interacting with sockets in the worker

Now that the SDK is completed, we can turn to the worker. The project is complex enough; we can refresh our memory with the mandelbrot-worker architecture:

We will start by implementing the Job class. Inside the mandelbrot-worker project, create a new C++ class named Job. Here is the Job.h content:

#include <QObject> 
#include <QRunnable> 
#include <QAtomicInteger> 
#include "JobRequest.h" 
#include "JobResult.h" 
class Job : public QObject, public QRunnable 
    explicit Job(const JobRequest& jobRequest,  
                 QObject *parent = 0); 
    void run() override; 
    void jobCompleted(JobResult jobResult); 
public slots: 
    void abort(); 
    QAtomicInteger<bool> mAbort; 
    JobRequest mJobRequest;
