    \class QCommonStyle
    \brief The QCommonStyle class encapsulates the common Look and Feel of a GUI.

    \ingroup appearance
    \inmodule QtWidgets

    This abstract class implements some of the widget's look and feel
    that is common to all GUI styles provided and shipped as part of
    Qt.

    Since QCommonStyle inherits QStyle, all of its functions are fully documented
    in the QStyle documentation.
    \omit
    , although the
    extra functions that QCommonStyle provides, e.g.
    drawComplexControl(), drawControl(), drawPrimitive(),
    hitTestComplexControl(), subControlRect(), sizeFromContents(), and
    subElementRect() are documented here.
