How to draw a Qgraphicsitem on a Qimage?

[wysota]

As I have mentioned in the question, the most recent item is editable by the user.
ie, it can be dragged around, resized and rotated before the final permamnent version is drawn.
I thought this could be easier to implement with QGraphicsView

That doesn't require graphics view. Nevertheless my question still stands -- if your fill is to create a new "most recent item" that is to be "editable by the user" then it is much different from filling an existing item or canvas.

Actually 'editable' apply to only a selected few items in the application. This excludes floodfills and freehand lines.
