qgraphicsitem_cast problem

After compiling the code, i have this 3 error:

moc_pixmapitem.cpp:40: error: ‘staticMetaObject’ is not a member of ‘QGraphicsPixmapItem’

moc_pixmapitem.cpp:54: error: ‘qt_metacast’ is not a member of ‘QGraphicsPixmapItem’

moc_pixmapitem.cpp:59: error: ‘qt_metacall’ is not a member of ‘QGraphicsPixmapItem’

I have this error, when i inserted this line of code in my MainWIndow application:

Code:

---

QGraphicsItem* item;
if(item->type() == pixmapItem::Type)
			qgraphicsitem_cast<pixmapItem *>(item);

---

I add to pixmapitem.h file:

Code:

---

public:
enum { Type = UserType + 2 };
int type() const{return Type;}

---

What's wrong???

I had a public slot function in pixmapItem class.....so i put this function in a public section(without slot) and so resolve the problem............:D
