    \brief Demonstrates anchor layout on a graphics view scene.

    The Simple Anchor Layout example shows the basic use of the
    QGraphicsAnchorLayout class.

           {Application using anchor layouts to place widgets}


    The example starts by creating a QGraphicsScene (\c scene), 3 widgets
    (\c a, \c b, and \c c), and a QGraphicsAnchorlayout (\c layout).

    \quotefromfile graphicsview/simpleanchorlayout/main.cpp
    \skipto QGraphicsScene
    \printuntil QGraphicsAnchorLayout

    First it anchors the top left corner of item \c a to the top left
    corner of \c layout. This can be done in two steps:

    \skipto layout->addAnchor(a
    \printto adding

    Or in one step:

    \skipuntil [adding a corner anchor]
    \printline layout->addCornerAnchors(a, Qt::T

    Then the right anchor of \c a is anchored to the left anchor of
    \c b, and the top of item \c b is anchored to the bottom of \c a.

    \skipuntil [adding anchors]
    \printto adding anchors

    Place a third widget \c c under widget \c b:

    \skipuntil third widget
    \printline AnchorBottom

    Items \c b and \c c are anchored to each other horizontally:

    \skipto Qt::Horizontal
    \printline Qt::Horizontal

    Item c is anchored to the bottom right point of \c layout

    \skipuntil corner of the layout
    \printline Qt::BottomRightCorner

    Finally, QGraphicsWidget \c w is displayed in QGraphicsView \c view.

    \skipto QGraphicsWidget
    \printuntil app.exec()
