    How to get x,y after addItem ?
    It seems first setPos() then can get Pos().
    If don not setPos(), pos() = (0,0).

    ......
    QGraphicsRectItem *GRI = scene->addRect(x, y, w, h, pen, brush);
    QGraphicsEllipseItem *GEI = scene->addEllipse(x, y, w, h, pen, brush);
    QGraphicsTextItem *GTI = scene->addText(text, font);
    GTI->setPos(QPoint(x,y));
    ......
    QList<QGraphicsItem*> list_GI = scene->items(Qt::AscendingOrder);
    for(int i=0; i<list_GI.count(); i++){
        qDebug() << list_GI.at(i)->x() << list_GI.at(i)->y(); // 0 0
        qDebug() << list_GI.at(i)->width() << list_GI.at(i)->height(); // no these function
    }

      Hi,

      Do you mean the QGraphicsItem::pos method ?
