Hi,
I am currently developing a small graphic application. It consist on a QMainWindow with a QGraphicsScene as centralwidget !
I want to implement a function that, when the application is closed, will check if the graphicsScene modifications (add/delete/move graphics items) are saved to an XML file. I know this function:
changed ( const QList<QRectF> & region )
I don’t know how to use it ! It sometimes work and sometimes don’t !
any idea ?
