making screen follow Qgraphicsitem

How is it possible to make screen follow QGraphicsItem?
I am trying to make a game and I need that screen follows the player, is there any class I can call or something?

There are many QGraphicsView methods that control what part of the scene is displayed in the view:

QGraphicsView::centerOn()
QGraphicsView::ensureVisible()
QGraphicsView::fitInView()
QGraphicsView::setSceneRect(), etc.

One of these will probably do what you need.

I am trying to work with centerOn, but can't make it work :s..

My code looks like this and the centerOn is not doing anything.


Creating scene:

Code:

---

self.scene = QtWidgets.QGraphicsScene()
self.scene.setSceneRect(0, 0, 700, 700)
 self.view = QtWidgets.QGraphicsView(self.scene, self)

---

Creating rect, that player can control:

Code:

---

self.item = QtWidgets.QGraphicsRectItem(-300, 500, 50, 50)
self.item.setBrush(QtGui.QBrush(QtGui.QColor(color[0], color[1],color[2]), QtCore.Qt.SolidPattern))
self.scene.addItem(self.item)
self.newplayer = Player(color, self.starting, self.item, self.view)

---

And in Players class init function I am trying to call:

Code:

---

self.view.centerOn(self.item)
