    \class QStyleOption
    \brief The QStyleOption class stores the parameters used by QStyle functions.

    \ingroup appearance

    QStyleOption and its subclasses contain all the information that
    QStyle functions need to draw a graphical element.

    For performance reasons, there are few member functions and the
    access to the member variables is direct (i.e., using the \c . or
    \c -> operator). This low-level feel makes the structures
    straightforward to use and emphasizes that these are simply
    parameters used by the style functions.

    The caller of a QStyle function usually creates QStyleOption
    objects on the stack. This combined with Qt's extensive use of
    \l{implicit sharing} for types such as QString, QPalette, and
    QColor ensures that no memory allocation needlessly takes place.

    The following code snippet shows how to use a specific
    QStyleOption subclass to paint a push button:

    \snippet doc/src/snippets/qstyleoption/main.cpp 0

    In our example, the control is a QStyle::CE_PushButton, and
    according to the QStyle::drawControl() documentation the
    corresponding class is QStyleOptionButton.

    When reimplementing QStyle functions that take a QStyleOption
    parameter, you often need to cast the QStyleOption to a subclass.
    For safety, you can use qstyleoption_cast() to ensure that the
    pointer type is correct. For example:

    \snippet doc/src/snippets/qstyleoption/main.cpp 4

    The qstyleoption_cast() function will return 0 if the object to
    which \c option points is not of the correct type.

    For an example demonstrating how style options can be used, see
    the \l {widgets/styles}{Styles} example.

    \sa QStyle, QStylePainter

/*!
    \enum QStyleOption::OptionType

    This enum is used internally by QStyleOption, its subclasses, and

    create your own QStyleOption subclass and your own styles.

    \class QStyleOptionFrame
    \brief The QStyleOptionFrame class is used to describe the
    parameters for drawing a frame.

    QStyleOptionFrame is used for drawing several built-in Qt widgets,
    including QFrame, QGroupBox, QLineEdit, and QMenu. Note that to
    describe the parameters necessary for drawing a frame in Qt 4.1 or
    above, you must use the QStyleOptionFrameV2 subclass.

    An instance of the QStyleOptionFrame class has
    \l{QStyleOption::type} {type} SO_Frame and \l{QStyleOption::version}
    {version} 1.

    The type is used internally by QStyleOption, its subclasses, and
    qstyleoption_cast() to determine the type of style option. In
    general you do not need to worry about this unless you want to
    create your own QStyleOption subclass and your own styles.  The
    version is used by QStyleOption subclasses to implement extensions
    without breaking compatibility. If you use qstyleoption_cast(),
    you normally do not need to check it.

    If you create your own QStyle subclass, you should handle both
    QStyleOptionFrame and QStyleOptionFrameV2.

    QStyleOptionFrameV2 inherits QStyleOptionFrame which is used for

    An instance of the QStyleOptionFrameV2 class has

    you normally do not need to check it.

    If you create your own QStyle subclass, you should handle both
    QStyleOptionFrame and QStyleOptionFrameV2. One way to achieve this
    is to use the QStyleOptionFrameV2 copy constructor. For example:

    \snippet doc/src/snippets/qstyleoption/main.cpp 1

    In the example above: If the \c frameOption's version is 1, \l
    FrameFeature is set to \l None for \c frameOptionV2. If \c
    frameOption's version is 2, the constructor will simply copy the
    \c frameOption's \l FrameFeature value.

    An instance of the QStyleOptionTabV3 class has
    \l{QStyleOption::type} {type} \l SO_Tab and
    \l{QStyleOption::version} {version} 3. The type is used internally
    by QStyleOption, its subclasses, and qstyleoption_cast() to

    worry about this unless you want to create your own QStyleOption
    subclass and your own styles. The version is used by QStyleOption
    subclasses to implement extensions without breaking
    compatibility. If you use qstyleoption_cast(), you normally do not
    need to check it.

    If you create your own QStyle subclass, you should handle both
    QStyleOptionTab, QStyleOptionTabV2 and QStyleOptionTabV3.
    One way to achieve this is to use the QStyleOptionTabV3 copy
    constructor. For example:

    \snippet doc/src/snippets/qstyleoption/main.cpp 3

    In the example above: If \c tabOption's version is 1, the extra
    member (\l{QStyleOptionTabV2::iconSize}{iconSize}) will be set to
    an invalid size for \c tabV2.  If \c tabOption's version is 2, the
