Cannot disconnect server child client
-
In my Window Qt application, I've created a server and assigned it to listen to a particular ip address/port. I am able to make connection with a client and communicate with it. However, an issue I seem to be running into is that when my application closes, I am unsuccessfully disconnecting my client socket, causing my server to close unsuccessfully. This then causes my application to unsuccessfully connect to the client the next time my application starts. I will have to reboot the pc to get the port to reset. My current code is as follow:
@
// Server code
Server::Server(QObject *parent)
: QTcpServer(parent)
{
client = NULL;
connect(this, SIGNAL(newConnection()), this, SLOT(handleNewConnection()));
}
Server::~Server()
{
}void Server::handleNewConnection()
{
client = nextPendingConnection();
connect(client, SIGNAL(readyRead()), this, SLOT(onSocketReadyRead()));
}
void Server::onSocketReadyRead()
{
char buffer[1024] = {0};
client->read(buffer, client->bytesAvailable());
emit DisplayString(this, QString(&buffer[0]));
}
void Server::SendCommand(QString str)
{
if (client != NULL)
{
int n = client->write(str.toUtf8());
qDebug() << "length: " << n << "string: " << str;
}
}
void Server::DisconnectClient()
{
if (client != NULL && client->isOpen())
{
client->disconnectFromHost();
client->deleteLater();
client = NULL;
}
}// instantiating server from main
server[0] = new Server();
server[0].listen(QHostAddress::LocalHost, 5000);// disconnecting routine in main
server[0].DisconnectClient();
server[0].close();@
Can someone tell me how I can disconnect my client socket from my server properly? I am using command line "netstat" to view my port status and the code above does not seem to destroy my client socket. Thanks!
