I'm afraid that doesn't help for my use case, since I need the images to appear as clear and clean as possible when being scaled down.

@Mquaza said in QPainter drawRects without draging a line behind: How do you make it so, that 2 rectangles are moving across the scene? I would say change their coordinates?

@raven-worx I think that it's the same rectan[i]/rectan.at(i) . I solved the problem,: QGraphicsRectItem *tempi = new QGraphicsRectItem; tempi->setRect(rectan.at(i)); draw_rectan.append(tempi); I think it was overwriting data

Glad you solved it! :-)
