[Interest] draw text and shape on an image using QGraphicsView

[Mehmet İpek]

I suggest you to create a QGraphicsTextItem in mousePressEvent function.
Don't use QPainter to draw graphics if you are using QGraphicsView. Btw,
your code shouldn't be compiled. QPainter constructor takes QPaintDevice*
and you are giving QGraphicsScene* which is derived from QObject.
