自己写了一个类继承QTcpServer，重写里面的incomingConnection函数，但是当有新的客户端连接的时候无法进入这个函数。
头文件
```class TcpServerManager : public QTcpServer
{
Q_OBJECT
public:
TcpServerManager(QObject parent);
~TcpServerManager();
QList<TcpSocketManager> mSocketList;
void ReadUserInfo();
public slots:
void ServerNewConnection();
void ServerReadData();
void slotclientdisconnect(qintptr descriptor);
void sliotupdateserver(QString, int);
private:
QTcpSocket mp_TCPSocket;
QTcpServer mp_TCPServer;
std::map mMapUserInfo;
protected:
virtual void incomingConnection(qintptr socketDescriptor);
};
cpp
TcpServerManager::TcpServerManager(QObject *parent)
: QTcpServer(parent)
{
ReadUserInfo();
mp_TCPServer = new QTcpServer();
mp_TCPSocket = new QTcpSocket();
if (!mp_TCPServer->listen(QHostAddress::Any, 9988))
{
QMessageBox::warning(NULL, QString::fromLocal8Bit("提示"), QString::fromLocal8Bit("服务器端监听失败！"), QMessageBox::Yes);
return;
}
//connect(mp_TCPServer, SIGNAL(newConnection()), this, SLOT(ServerNewConnection()));
}
TcpServerManager::~TcpServerManager()
{
}
void TcpServerManager::incomingConnection(qintptr socketDescriptor)
{
TcpSocketManager *tcpclientsocket = new TcpSocketManager(this);
tcpclientsocket->setSocketDescriptor(socketDescriptor);
mSocketList.append(tcpclientsocket);
connect(tcpclientsocket, &TcpSocketManager::clientdisconnected, this, &TcpServerManager::slotclientdisconnect);
connect(tcpclientsocket, &TcpSocketManager::updateserver, this, &TcpServerManager::sliotupdateserver);
}
