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 :
Qt Code: 
  1. // Local includes
  2. #include "main.h"
  3.  
  4. // Constructor of the timer class
  5. Timer::Timer(QObject *parent) : QObject(parent)
  6. {
  7.     qDebug() << "inConstrutor";
  8.     QTimer *timer = new QTimer();
  9.     connect(timer, SIGNAL(timeout()), this, SLOT(startBackup()));
  10.     timer->start(5000);
  11. }
  12.  
  13. // Start the backup
  14. int Timer::startBackup(){
  15.  
  16.     qDebug() << "inStart" << backingUP;
  17.     //return 0;
  18.  
  19.     if(backingUP){
  20.         return 2;
  21.     }
  22.  
  23.     // Start the backup thread
  24.     Backup *backup = new Backup();
  25.  
  26.     // Make a connection for deleting this later when done
  27.     //connect(backup, SIGNAL(finished()), backup, SLOT(deleteLater()));
  28.  
  29.     // Set that we are running ATM
  30.     backingUP = true;
  31.  
  32.     backup->start();
  33.  
  34.     return 1;
  35.  
  36. }
  37.  
  38. // The constructor
  39. Backup::Backup(QObject *parent)
  40.     : QThread(parent)
  41. {
  42.  
  43.     // This thread can never be terminated
  44.     //this->setTerminationEnabled(false);
  45. }
  46.  
  47. // The function that does everything
  48. void Backup::run()
  49. {
  50.  
  51.     this->doit();
  52.  
  53. }
  54.  
  55.  
  56. void Backup::doit(){
  57.  
  58.     qDebug() << "Doit";
  59.  
  60.     socket = new QSslSocket;
  61.  
  62.     connect(socket, SIGNAL(readyRead()),
  63.             this, SLOT(socketReadyRead()));
  64.     connect(socket, SIGNAL(sslErrors(QList<QSslError>)),
  65.             this, SLOT(sslErrors(QList<QSslError>)));
  66.     connect(socket, SIGNAL(stateChanged(QAbstractSocket::SocketState)),
  67.             this, SLOT(socketStateChanged(QAbstractSocket::SocketState)));
  68.     connect(socket, SIGNAL(encrypted()),
  69.             this, SLOT(socketEncrypted()));
  70.  
  71.     // Connect to the server
  72.     socket->connectToHostEncrypted(NSettings->value("hostname").toString(), NSettings->value("port").toInt());
  73.  
  74.     // Wait for it to reach the encryted and connected state
  75.     if (!socket->waitForEncrypted()) {
  76.         qDebug() << "waitForEncrypted Error";
  77.         return; // An error occured
  78.     }
  79.  
  80.     // This is the protocol
  81.     socket->write("ENTERHEADER\r\n");
  82.     socket->waitForBytesWritten();
  83.  
  84.     QByteArray username = NSettings->value("user").toByteArray();
  85.     QByteArray device = NSettings->value("device").toByteArray();
  86.  
  87.     // We first need to LOGIN
  88.     this->rite("L"+ username.toBase64() +" "+ device.toBase64());
  89.     socket->waitForBytesWritten();
  90.  
  91. }
  92.  
  93. // Called whenever there is something to READ in the buffer
  94. void Backup::socketReadyRead(){
  95.  
  96.     qDebug() << socket->bytesAvailable();
  97.     QString str = socket->readAll();
  98.     qDebug() << str;
  99.  
  100.     bool unconnected = !socket || socket->state() == QAbstractSocket::UnconnectedState;
  101.  
  102.     if(str == "LOGIN SUCCESSFUL"){
  103.  
  104.         for(int i = 1; i <= 1000; i++){
  105.  
  106.             // Was the login successful ?
  107.             if(unconnected){
  108.                 qDebug() << socket->state();
  109.                 return;
  110.             }
  111.  
  112.             this->rite("STORE ABC\r\n");
  113.             socket->waitForBytesWritten();
  114.         }
  115.  
  116.     }
  117.  
  118.     qDebug() << "End READ";
  119.  
  120.     // Disconnect from the server
  121.     //socket->disconnectFromHost();
  122.  
  123. }
  124.  
  125. // Called when the connection is fully established
  126. void Backup::socketEncrypted()
  127. {
  128.     qDebug() << "Connection Established";
  129. }
  130.  
  131. // Called when there are SSL errors
  132. void Backup::sslErrors(const QList<QSslError> &errors)
  133. {
  134.     foreach (const QSslError &error, errors){
  135.         qDebug() << error.errorString();
  136.     }
  137.  
  138.     // Ignore Errors
  139.     socket->ignoreSslErrors();
  140. }
  141.  
  142. // Whenever there is a change in the connection STATE, this is called
  143. void Backup::socketStateChanged(QAbstractSocket::SocketState state)
  144. {
  145.     qDebug() << state;
  146. }
  147.  
  148. // Socket write safe as it appends the length to the beginning of the string
  149. qint64 Backup::rite(const QByteArray & data)
  150. {
  151.     return socket->write(data);
  152. }

When I run this I get the following error :
Qt Code: 
  1. inConstrutor 
  2. inStart false 
  3. Doit 
  4. QObject::connect: Cannot queue arguments of type 'QAbstractSocket::SocketState'
  5. (Make sure 'QAbstractSocket::SocketState' is registered using qRegisterMetaType().)
  6. 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.
