Web Cam QThread Display One Frame Image and not Continuous Video

Hello to all, i need to develop an GUI window that capture video from web cam and display it to Qt main window but unfortunately it only display 1 frame image and not continuous video.

Code:

---

OpenCVQT::OpenCVQT(QWidget *parent, Qt::WFlags flags)
	: QMainWindow(parent, flags)
 
{
 ui.setupUi(this);
 
 myLabel = new QLabel("Fuckasdasd");
 mainLayout = new QVBoxLayout;
 
 mainLayout->addWidget(myLabel);
 
 mainWgt = new QWidget(this);
 
 mainWgt->setLayout(mainLayout);
 this->setCentralWidget(mainWgt);
 
 
 camMenu = menuBar()->addMenu(tr("Web Camera"));
 webCamAct = new QAction(tr("Start Web Camera"), this );
 camMenu->addAction(webCamAct); 
 connect(webCamAct, SIGNAL(triggered()), this, 
  SLOT(WebCamSlot() ));
 
 myCamThread = new cameraThread();
 
}
// =============================================
OpenCVQT::~OpenCVQT()
{
}
// =============================================
QLabel*& OpenCVQT::getLabel()
{
 return myLabel;
}
 
void OpenCVQT::WebCamSlot()
{
 myCamThread->run();
}
 
class cameraThread : public QThread
{
public:
 cameraThread();
 ~cameraThread();
 
 void run();
 void StreamCamera();
 void ConvertImage();
 void CreateQImage();
 
private: 
 CvCapture* myCaptureHandler;
 IplImage* myOriginalIplImage, *myRGBIplImage;
 
 QImage myQImage;
 uchar* ImageData;
 
};
 
cameraThread::cameraThread()
  : myCaptureHandler(), 
	myOriginalIplImage(&IplImage() ), 
	myRGBIplImage(&IplImage() ), 
	myQImage(QImage()), 
	ImageData()
{
 myCaptureHandler = cvCreateCameraCapture(0);
 myOriginalIplImage = cvCreateImage(cvSize(320, 240), 
   IPL_DEPTH_8U, 3);
 
 myRGBIplImage = cvCreateImage(cvSize(320,240), 
  IPL_DEPTH_8U, 3 );
 
}
// =============================================
cameraThread::~cameraThread()
{
}
// =============================================
void cameraThread::run()
{
 StreamCamera();
 exec();
}
// =============================================
void cameraThread::StreamCamera()
{
 myOriginalIplImage = cvQueryFrame(myCaptureHandler);
 
 ConvertImage();
 CreateQImage();
 
 //resize(myRGBIplImage->width, myRGBIplImage->height);   
 (OpenCVQT::myLabel)->setPixmap(QPixmap::fromImage(myQImage)  );
 
 
}
// =============================================
void cameraThread::ConvertImage()
{
 cvCvtColor(myOriginalIplImage, 
  myRGBIplImage, CV_BGR2RGB); 
 
 if (!myRGBIplImage)
 {
  QErrorMessage* errMsg = new QErrorMessage;
  errMsg->showMessage("Error Convert Image");
 }
 else
 {
  ImageData = (uchar*) myRGBIplImage->imageData;
 }
 
} 
// =============================================
void cameraThread::CreateQImage()
{
 myQImage = QImage(ImageData, 
  myRGBIplImage->width, myRGBIplImage->height, 
  myRGBIplImage->widthStep, 
  QImage::Format_RGB888);
}

Code:

---

void cameraThread::run()
{
 StreamCamera();
 exec();
}

I need the streamCamera() to be continuous running while main window is running too.

Please help.

Thanks.
