QSslSocket and QThread

? Offline

Hi,

I am trying to get a QSslSocket to work in QThread but I cant seem to get it to work.
The following is the code :
@
// Local includes
#include "main.h"

// Constructor of the timer class
Timer::Timer(QObject *parent) : QObject(parent)
{
qDebug() << "inConstrutor";
QTimer *timer = new QTimer();
connect(timer, SIGNAL(timeout()), this, SLOT(startBackup()));
timer->start(5000);
}

// Start the backup
int Timer::startBackup(){

qDebug() << "inStart" << backingUP;
//return 0;

if(backingUP){
    return 2;
}

// Start the backup thread
Backup *backup = new Backup();

// Make a connection for deleting this later when done
//connect(backup, SIGNAL(finished()), backup, SLOT(deleteLater()));

// Set that we are running ATM
backingUP = true;

backup->start();

return 1;

}

// The constructor
Backup::Backup(QObject *parent)
: QThread(parent)
{

// This thread can never be terminated
//this->setTerminationEnabled(false);

}

// The function that does everything
void Backup::run()
{

this->doit();

}

void Backup::doit(){

qDebug() << "Doit";

socket = new QSslSocket;

connect(socket, SIGNAL(readyRead()),
        this, SLOT(socketReadyRead()));
connect(socket, SIGNAL(sslErrors(QList<QSslError>)),
        this, SLOT(sslErrors(QList<QSslError>)));
connect(socket, SIGNAL(stateChanged(QAbstractSocket::SocketState)),
        this, SLOT(socketStateChanged(QAbstractSocket::SocketState)));
connect(socket, SIGNAL(encrypted()),
        this, SLOT(socketEncrypted()));

// Connect to the server
socket->connectToHostEncrypted(NSettings->value("hostname").toString(), NSettings->value("port").toInt());

// Wait for it to reach the encryted and connected state
if (!socket->waitForEncrypted()) {
    qDebug() << "waitForEncrypted Error";
    return; // An error occured
}

// This is the protocol
socket->write("ENTERHEADER\r\n");
socket->waitForBytesWritten();

QByteArray username = NSettings->value("user").toByteArray();
QByteArray device = NSettings->value("device").toByteArray();

// We first need to LOGIN
this->rite("L"+ username.toBase64() +" "+ device.toBase64());
socket->waitForBytesWritten();

}

// Called whenever there is something to READ in the buffer
void Backup::socketReadyRead(){

qDebug() << socket->bytesAvailable();
QString str = socket->readAll();
qDebug() << str;

bool unconnected = !socket || socket->state() == QAbstractSocket::UnconnectedState;

if(str == "LOGIN SUCCESSFUL"){

    for(int i = 1; i <= 1000; i++){

        // Was the login successful ?
        if(unconnected){
            qDebug() << socket->state();
            return;
        }

        this->rite("STORE ABC\r\n");
        socket->waitForBytesWritten();
    }

}

qDebug() << "End READ";

// Disconnect from the server
//socket->disconnectFromHost();

}

// Called when the connection is fully established
void Backup::socketEncrypted()
{
qDebug() << "Connection Established";
}

// Called when there are SSL errors
void Backup::sslErrors(const QList<QSslError> &errors)
{
foreach (const QSslError &error, errors){
qDebug() << error.errorString();
}

// Ignore Errors
socket->ignoreSslErrors();

}

// Whenever there is a change in the connection STATE, this is called
void Backup::socketStateChanged(QAbstractSocket::SocketState state)
{
qDebug() << state;
}

// Socket write safe as it appends the length to the beginning of the string
qint64 Backup::rite(const QByteArray & data)
{
return socket->write(data);
}
@

When I run this I get the following error :
@inConstrutor
inStart false
Doit
QObject::connect: Cannot queue arguments of type 'QAbstractSocket::SocketState'
(Make sure 'QAbstractSocket::SocketState' is registered using qRegisterMetaType().)
waitForEncrypted Error
@

If I dont call the backup->start(); and call the backup->doit(); then the code works perfectly.
I would really be happy, if someone can shed any light on what I am doing wrong.
