    Default 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::setSceneRect(), etc.

    One of these will probably do what you need.

    Please use CODE tags when posting source code so it is more readable. Click "Go Advanced" and then the "#" icon to insert the tags. Paste your code between them.

    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:
    Qt Code:
    1. self.scene = QtWidgets.QGraphicsScene()
    2. self.scene.setSceneRect(0, 0, 700, 700)
    3. self.view = QtWidgets.QGraphicsView(self.scene, self)
    To copy to clipboard, switch view to plain text mode 

    Creating rect, that player can control:
    Qt Code:
    1. self.item = QtWidgets.QGraphicsRectItem(-300, 500, 50, 50)
    2. self.item.setBrush(QtGui.QBrush(QtGui.QColor(color[0], color[1],color[2]), QtCore.Qt.SolidPattern))
    3. self.scene.addItem(self.item)
    4. self.newplayer = Player(color, self.starting, self.item, self.view)
    To copy to clipboard, switch view to plain text mode 
    And in Players class init function I am trying to call:
    Qt Code:
    1. self.view.centerOn(self.item)
    To copy to clipboard, switch view to plain text mode
