class Server : public QObject { Q _ OBJECT public: explicit Server ( QObject * parent = 0 ) ; / / must be explicitly
class Server : public QObject
QOBJECT
public:
explicit ServerQObject parent ; must be explicitly called to create an object of the Server class. The constructor takes a single parameter of type QObject which is a pointer to an object of the QObject class or one of its subclasses The parameter is given a default value of nullptr or in older code which means that if the constructor is called without providing a value for parent, it will default to a null pointer.
signals:
void dataReceivedQByteArray;The dataReceived signal you provided declares a signal named dataReceived that takes a single parameter of type QByteArray. This signal indicates that an object of this class emits the dataReceived signal when it receives data, and it passes a QByteArray containing the received data as an argument.

Can you please draw a class diagram which include the following classes: QObject QTopSocket, Server, QByteArray, QTopServer. There must be attributes or methods in classes
