QGraphicsScene and multitouch widgets???

Hi, I am trying to rotate two QDials which I have added to a QGraphicsScene but only one dial can be rotated.
Below is my setup

Code:

---

#include <QtGui/QApplication>
int main(int argc, char *argv[])
{
	QApplication a(argc, argv);	
        QGraphicsScene scene; 
	QGraphicsView view(&scene);
        QWidget* widget=new QWidget;
	widget->setAttribute(Qt::WA_AcceptTouchEvents);
	widget->setFocusPolicy(Qt::NoFocus);
        createGUI(":/GUI.xml",widget); //this function creates all the widget in UI and adds them in widget.
        scene.addWidget(widget);
        view.setDragMode(QGraphicsView::ScrollHandDrag);
	view.setAttribute(Qt::WA_AlwaysShowToolTips);
        view.show(); //I cannot move two dials at once
 
        //widget.show(); // I can move two dials at once
	return a.exec();
}

---

What I want is to create UI from xml file and since I what to provide zoom in/out feature for the UI I have to use QGraphicsView and QGraphicsScene.
All the widgets that are created have 'setAttribute(Qt::WA_AcceptTouchEvents)' done. The problem is if I use QGraphicsView and QGraphicsScene I cannot multitouch widgets. I want to be able to rotate two dials at once. But if I use QWidget (which has all the widgets of UI) I can rotate two dials at once.
I see that QGraphicsItem has a function setsetAcceptTouchEvents() function to be able to accept touch events. So can QGraphicsItem (only) receive touch events in QGraphicsScene and not QWidget?
Or is there something wrong in my setup. I mean loading UI in a widget and the adding that widget into a scene?

Thanks
