    4646    The Basic Graphics Layouts example shows how to use the layout classes
    4747    in QGraphicsView: QGraphicsLinearLayout and QGraphicsGridLayout.

    117118
    118     The \c LayoutItem class is a subclass of QGraphicsWidget. It has a
    119     constructor, a destructor, and a reimplementation of the
    120     {QGraphicsItem::paint()}{paint()} function.
     119    The \c LayoutItem class is a subclass of QGraphicsLayoutItem and
     120    QGraphicsItem. It has a constructor, a destructor, and some required
     121    reimplementations.
     122    Since it inherits QGraphicsLayoutItem it must reimplement
     123    {QGraphicsLayoutItem::setGeometry()}{setGeometry()} and
     124    {QGraphicsLayoutItem::sizeHint()}{sizeHint()}.
     125    In addition to that it inherits QGraphicsItem, so it must reimplement
     126    {QGraphicsItem::boundingRect()}{boundingRect()} and
     127    {QGraphicsItem::paint()}{paint()}.

    124     The \c LayoutItem class also has a private instance of QPixmap, \c pix.
    125 
    126     \note We subclass QGraphicsWidget so that \c LayoutItem objects can
    127     be automatically plugged into a layout, as QGraphicsWidget is a
    128     specialization of QGraphicsLayoutItem.
     131    The \c LayoutItem class also has a private instance of QPixmap, \c m_pix.

    130133    \section1 LayoutItem Class Implementation
    131134
    132     In \c{LayoutItem}'s constructor, \c pix is instantiated and the
    133     \c{QT_original_R.png} image is loaded into it. We set the size of
    134     \c LayoutItem to be slightly larger than the size of the pixmap as we
    135     require some space around it for borders that we will paint later.
    136     Alternatively, you could scale the pixmap to prevent the item from
    137     becoming smaller than the pixmap.
     135    In \c{LayoutItem}'s constructor, \c m_pix is instantiated and the
     136    \c{block.png} image is loaded into it.
