    Hi,

    I'm trying to change the position of a pixmap, but it doesn't seem to be working:

    @iconview = QtGui.QGraphicsView()
    scn = QtGui.QGraphicsScene(iconView)
    scn.setSceneRect(iconView.sceneRect())
    iconView.setScene(scn)
    pix = QtGui.QPixmap("picture.xpm")
    item = QtGui.QGraphicsPixmapItem(scn.addPixmap(pix))
    item.setPos(0, 30) # for ex@

    It displays the picture, but doesn't move the position...just stays in the center.

    Thanks!!

        Your problem is with the following line:

        @scn.setSceneRect(iconView.sceneRect())@

        If you print out the result of sceneRect() you get:

        @QRectF(0.0, 0.0, 0.0, 0.0)@

        i.e. a rectangle of no size. This is because the QGraphicsView doesn't have a scene from which to get a size yet so returns default. If you set a size as follows your icon will be placed as desired:

        @scn.setSceneRect(QRectF(0.0, 0.0, 250.0, 250.0))@

        For the avoidance of doubt:

        1. All my code samples (C++ or Python) are tested before posting
        2. As of 23/03/20, my Python code is formatted to PEP-8 standards using black from the PSF (https://github.com/psf/black)
