Do i have to inherit from QTcpServer?

[p.kreker]

Hi,

I’m trying to create a threaded server and in every example I saw someone creates a server by inheriting from QTcpServer. So I wonder, do I have to? I mean, you inherit only if you want to extend the class.

Here is the class:
myserver.h

#ifndef MYSERVER_H
#define MYSERVER_H
 
#include <QObject>
#include <QtNetwork/QTcpServer>
#include <QtConcurrentRun>
#include <QFuture>
#include "myclienthandle.h"
 
class MyServer : public QObject
{
	Q_OBJECT
public:
	explicit MyServer(QObject *parent = 0, const QString &ip = "Any", int port = 0);
	explicit MyServer(const MyServer &server);
	~MyServer();
	QString IP() const;
	void setIP(const QString &ip);
	int Port() const;
	void setPort(int port);
	bool isAlive() const;
 
 
private:
	QTcpServer *m_qtcpserListener;
	QFuture<void> m_qftrRun;
	QString *m_qstrIP;
	int m_iPort;
	int m_iClientID;
	bool m_bRun;
 
	void run();
 
signals:
	void newConnection(MyClientHandle *clientHandle);
 
public slots:
	void start();
	void stop();
};
 
inline QString MyServer::IP() const
{
	return *m_qstrIP;
}
 
inline void MyServer::setIP(const QString &ip)
{
	m_qstrIP = new QString(ip);
}
 
inline int MyServer::Port() const
{
	return m_iPort;
}
 
inline void MyServer::setPort(int port)
{
	m_iPort = port;
}
 
inline bool MyServer::isAlive() const
{
	return m_bRun;
}

inline QString MyServer::IP() const
{
	return *m_qstrIP;
}

inline void MyServer::setIP(const QString &ip)
{
	m_qstrIP = new QString(ip);
}

inline int MyServer::Port() const
{
	return m_iPort;
}

inline void MyServer::setPort(int port)
{
	m_iPort = port;
}

inline bool MyServer::isAlive() const
{
	return m_bRun;
}
