QGraphcisView issue with mouse cursor image

Hi,

I am using QGraphicsView for my application. I allow panning on ctrl+mousemove event. And when I release ctrl key, the view's drag mode is set to NoScroll. But in this case also when I press left mouse button , the mouse icon is changed to Qt::OpenHandCursor, which usually comes if the view allows panning.

Does any one know how to deal with this issue.
Below is the code snippet

Code:

---

void MyGraphicsView::keyReleaseEvent(QKeyEvent* event)
{
	if (event->key()==Qt::Key_Control)
	{
		m_DragMode=NO_DRAG;
		setDragMode(QGraphicsView::NoDrag);
	}
}
 
void MyGraphicsView::keyPressEvent(QKeyEvent* event)
{	
	//ctrl key is pressed
	if (event->key()==Qt::Key_Control)
	{
		m_DragMode=SCROLL_HANDLE_DRAG;
		setDragMode(QGraphicsView::ScrollHandDrag);
	}
}
