    \class QCleanlooksStyle
    \brief The QCleanlooksStyle class provides a widget style similar to the
    Clearlooks style available in GNOME.
    \since 4.2

    The Cleanlooks style provides a look and feel for widgets
    that closely resembles the Clearlooks style, introduced by Richard
    Stellingwerff and Daniel Borgmann.
