    \class QWindowsXPStyle
    \brief The QWindowsXPStyle class provides a Microsoft WindowsXP-like look and feel.

    \ingroup appearance

    \warning This style is only available on the Windows XP platform
    because it makes use of Windows XP's style engine.

    Most of the functions are documented in the base classes
    QWindowsStyle, QCommonStyle, and QStyle, but the
    QWindowsXPStyle overloads of drawComplexControl(), drawControl(),
    drawControlMask(), drawPrimitive(), subControlRect(), and
    sizeFromContents(), are documented here.
