How do I mange QGraphicsScene's items position? Everytime I add a new item on my scene it gets centralized.Why does it do that?

use QGraphicsItem::setPos()

The item must be positioned anywhere, but that's no problem where since you have to arrange the items in the screen by yourself using the above mentioned function.

This is how I'm adding the pixmap:

scene->addItem(new QGraphicsPixmapItem(tempIcon.pixmap(100,QIcon::Normal,QIcon::On)));

scene->addItem(new QGraphicsPixmapItem(tempIcon.pixmap(100,QIcon::Normal,QIcon::On)));

How do I set its position if there was no name given to the QGraphicsPixmapItem?

you have to save the item in a member pointer or other global pointer... ther are other ways like findItem but that would be unecessary slow

you can rewrite this in following way:

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);

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);

Yes of course, but as said, you have to take care yourself for the arrangement of the items in the scene. (Or you could use QGraphicsLinearLayout)

[been_1990]

Does QGraphicsLinearLayout automatically arrange the QGraphicsScene items in rows? Like

0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0

0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0
0  0   0  0  0  0  0  0

If it does, how do I implement it? Do I just add the scenes items to a QGraphicLinear layout? Does it also modify the height and width of the item if requested?
