QGraphicsScene item positioning

[been_1990]

Wont things mess up if I continually call a function with

QGrphicsPixmapItem* item = new QGraphicsPixmapItem(tempIcon.pixmap(100,QIcon::Normal,QIcon::On);
item->setPos(100, 100); 
scene->addItem(item);

QGrphicsPixmapItem* item = new QGraphicsPixmapItem(tempIcon.pixmap(100,QIcon::Normal,QIcon::On);
item->setPos(100, 100); 
scene->addItem(item);
