rotation of an animated QGraphicsItem

[Bitto]

That depends on the item - sometimes it's easier to replace one line than to rewrite all your coordinates ;-).

what about QGraphicsSvgItem. It already implements boundingRect() which returns 0,0 as Point of origin for one Item I'm testing here. Can I also handle that doing a transformation? Redefining boundingRect seemingly isn't an option here ...

Thanx in advance

You can always do the translation in the item's paint routine. Also a single line

momesana, you can just use the translate-rotate-translate trick from above, it works for any item and you don't have to modify it / subclass it / change its bounding rect or painting.

wysota, you'd have to translate the bounding rect, the shape, and the painter inside the paint() function. otherwise you'd get painting and collision artifacts.
