mouseMoveEvent in QGraphicsItem

[navi1084]

Dear All,
I have re-implemented mouseMoveEvent(QGraphicsSceneMouseEvent *event) in my class which is derived from QGraphicsItem. When i draw an item on scene and move the mouse cursor inside the item, mouseMoveEvent() will not trigger. It will only trigger when i click on the item and move the mouse inside the item (i.e leftclick + move). I have set the setAcceptHoverEvents(true). But still mouseMoveEvent() event doesn't trigger. Can anyone tell how can i resolve this problem such that, mouse move on item trigger mouseMoveEvent(). Following is my code

CMyItem::CMyItem(QPointF center, QSizeF size)
{
	m_Rectangle.setSize(size);
	m_Rectangle.moveTopLeft(center);
	setZValue(((int)m_Rectangle.top() +  (int)m_Rectangle.left())% 2);
 
	setFlags(ItemIsSelectable | ItemIsMovable);
    setAcceptHoverEvents(true);
}
 
CMyItem::~CMyItem()
{
 
}
 
QRectF CMyItem::boundingRect() const
{
    return QRectF(0, 0, 200, 100);
}
 
QPainterPath CMyItem::shape() const
{
    QPainterPath path;
    path.addRect(0, 0, 200, 100);
    return path;
}
 
void CMyItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget)
{
    Q_UNUSED(widget);
	//QBrush brush(
	QPen pen;
	pen.setColor(Qt::black);
	painter->setPen(pen);
	painter->drawRect(m_Rectangle);
}
 
void CMyItem::mousePressEvent(QGraphicsSceneMouseEvent *event)
{
    QGraphicsItem::mousePressEvent(event);
    update();
	event->accept();
 
}
 
void CMyItem::mouseMoveEvent(QGraphicsSceneMouseEvent *event)
{
     QGraphicsItem::mouseMoveEvent(event);
}
 
void CMyItem::mouseReleaseEvent(QGraphicsSceneMouseEvent *event)
{
    QGraphicsItem::mouseReleaseEvent(event);
    update();
}

CMyItem::CMyItem(QPointF center, QSizeF size)
{
	m_Rectangle.setSize(size);
	m_Rectangle.moveTopLeft(center);
	setZValue(((int)m_Rectangle.top() +  (int)m_Rectangle.left())% 2);

	setFlags(ItemIsSelectable | ItemIsMovable);
    setAcceptHoverEvents(true);
}

void CMyItem::mousePressEvent(QGraphicsSceneMouseEvent *event)
{
    QGraphicsItem::mousePressEvent(event);
    update();
	event->accept();
