I have cards in my scene. For example in this code i tried to move my ManikenCard object to another position, but can't do this, because my moving methods don't respond to my clicks (i add "print" to this methods ).I noticed, that i can click on my Card and it raise MausePressEvent , and it say that only my drag-and-drop system doesn't work . How can i move my cards on the field. I read this article Drag n Drop inside QgraphicsView doesn't work (PyQt) with the similar problem, but can't do this in my own program .
