(C++) QGraphicsView

 

QGraphicsView is a Qt class to visualize a QGraphicsScene on screen.

 

The graphical items ('sprites') are added to the QGraphicsScene and are of type QGraphicsItem (see QGraphicsItem for a list of derived classes).

 

The layouts of the graphical items are of type QGraphicsLayout (see QGraphicsLayout for a list of derived classes).
