QTcpServer nextPendingConnection() problem

[teodori.serge]

Hello,
I need to pass a socket structure to an another object.

On the attached file you see a part of my program.

The problem is in the methode "void ChatNetworkManager::ClientConnection()",
ChatNetworkManager is a TCP Server (inherits : public QTcpServer)
ChatNetworkServer is a TCP Socket (inherits : public QTcpSocket)

nextPendingConnection() returns a QTcpSocket, but I have an object "ChatNetworkServer" that inherits QTcpSocket,
so I tried with "qobject_cast<>()", but the SIGNALs & SLOTs aren't working (QObject::connect : Cannot connect (null)::)

after that I tried various things like "setSocketDescriptor", or "setPeerAddress", etc...
those things work but sometimes I get errors (events lost, SEGMENTATION FAULTS, etc...)

is there a possibility like m_chatNetworkServer->copySocket(nextPendingConnection())

Thank you.


#include "chatnetworkmanager.h"

ChatNetworkManager::ChatNetworkManager(QObject *parent, quint16 port, int maxPeer) : QTcpServer(parent)
{
setMaxPendingConnections(maxPeer);
listen(QHostAddress::Any, port);

if(isListening())
{
QObject::connect(this, SIGNAL(newConnection()), this, SLOT(ClientConnection()));
m_serverStatus = QString("The server is listening on port : ") + QString::number(serverPort());
}
else
{
m_serverStatus = errorString();
}
}

QString ChatNetworkManager::ServerStatus()
{
return m_serverStatus;
}

void ChatNetworkManager::ClientConnection()
{
ChatNetworkServer *connection = new ChatNetworkServer(this);
connection = qobject_cast<ChatNetworkServer *>(nextPendingConnection());

m_list.append(connection);

QObject::connect(connection, SIGNAL(disconnected()), this, SLOT(DisConnectedFromServer()));
QObject::connect(connection, SIGNAL(DataRecieved(QString)), this, SLOT(SendToAll(QString)));
}

void ChatNetworkManager::DisConnectedFromServer()
{
ChatNetworkServer *disconnection = qobject_cast<ChatNetworkServer *>(sender());
if(disconnection == 0)
{
return;
}

m_list.removeOne(disconnection);
disconnection->deleteLater();
}

void ChatNetworkManager::SendToAll(const QString &forward)
{
for(int i = 0; i < m_list.size(); i++)
{
m_list[i]->SendData(forward);
}
}


Added after 5 minutes:

I cannot use "QTcpSocket" instead of "ChatNetworkServer", because the "ChatNetworkServer" class is not only a tcp socket but also SQL connection and has lots of functions inside (would be to hard to handle)
The "ChatNetworkManager" class is much greater than that, this is just a part of the class.

:) any help would be nice.

1. Your naming sucks very hard!
Do not call the server the manager and the client sockets the servers.
If this doesn't confuse you, you're in a league of extraordinary gentlemen!

2. What is the purpose of:

ChatNetworkServer *connection = new ChatNetworkServer(this);
connection = qobject_cast<ChatNetworkServer *>(nextPendingConnection());
