Hi
Whether Graphics drawing is supported?QGraphicsItem::painter () can be instead of qnanopainter?

[QUItCoding]

I have't used QGraphicsScene & QGraphicsView for a while since Qt Quick came... I think QGraphicsItem depends so much on QPainter that replacing it with QNanoPainter isn't straightforward. But I haven't tried so don't know 😃

I find it very difficult to modify the QGraphicsView framework with qnanopainter. I wonder if there is any plan to help me to see how difficult the modification will be.
thank you

I think it would help if you can clarify what you want. Do you want to patch Qt, changing the whole QGraphicsView? You plan to subclass QGraphicsView in your application or library and override it's behavior? You want to replace all of the painting, or just a part?

I want to use QNanopainter in the Paint of Graphicsitem
Like the follow codes
old style: paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget) new style: paint(QNanopainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget)
