QTcpsocket - connection problem

I have code like this to connect my server.

m_socket = new QTcpSocket();

connect( (QObject * ) m_socket, SIGNAL( proxyAuthenticationRequired ( const QNetworkProxy &, QAuthenticator *) ),this, SLOT( proxyAuthenticationRequiredFunction (

const QNetworkProxy &, QAuthenticator * ) ));

/*! To connect the server */
void ACMClient::connectToServer()
//************************************************** ****
{
m_networkProxy.setHostName("xx.xx.xx.xx");
m_networkProxy.setPort(3128);
m_networkProxy.setUser("username");
m_networkProxy.setPassword("password");
m_networkProxy.setType(QNetworkProxy::HttpProxy);
m_socket->setProxy(m_networkProxy);

m_socket->connectToHost("xx.xx.xx.xx",3456,QIODevice::ReadW rite);
}



proxyAuthenticationRequired signal is not emitted when i am tring to connect the server with proxy settings and i got the below error

QAbstractSocket::HostLookupState
QAbstractSocket::ConnectingState

QAbstractSocket::UnconnectedState
socket errorss QAbstractSocket::UnknownSocketError

It is because you make an explicit cast to QObject when you make the connect. There is no need to do that, just pass the socket pointer.

Code:

---

connect( m_socket, SIGNAL( proxyAuthenticationRequired ( const QNetworkProxy &, QAuthenticator *) ),this, SLOT( proxyAuthenticationRequiredFunction ( 
 
const QNetworkProxy &, QAuthenticator * ) ));

---
