Interacting with sockets from the application

The next project to complete is mandelbrot-app. It will contain the QTcpServer that will interact with the workers and the picture drawing of the Mandelbrot set. As a reminder, the diagram of the mandelbrot-app architecture is shown here:

We will build this application from the ground up. Let's start with the class responsible for maintaining the connection with a specific Worker: WorkerClient. This class will live in its specific QThread and will interact with a Worker class using the same  QTcpSocket/QDataStream mechanism we covered in the last section.

In mandelbrot-app, create a new C++ class named WorkerClient and update  WorkerClient.h like so:

#include <QTcpSocket> 
#include <QList> 
#include <QDataStream> 
 
#include "JobRequest.h" 
#include "JobResult.h" 
#include "Message.h" 
 
class WorkerClient : public QObject 
{ 
    Q_OBJECT 
public: 
    WorkerClient...
