    \class QMacStyle

    \brief The QMacStyle class provides a Mac OS X style using the Apple Appearance Manager.

    \ingroup appearance

    This class is implemented as a wrapper to the HITheme

    APIs, allowing applications to be styled according to the current

    theme in use on Mac OS X. This is done by having primitives

    in QStyle implemented in terms of what Mac OS X would normally theme.

    \warning This style is only available on Mac OS X because it relies on the

    HITheme APIs.

    There are additional issues that should be taken

    into consideration to make an application compatible with the

    \link http://developer.apple.com/documentation/UserExperience/Conceptual/OSXHIGuidelines/index.html

    Apple Human Interface Guidelines \endlink. Some of these issues are outlined

    below.

    \list

    \i Layout - The restrictions on window layout are such that some

    aspects of layout that are style-dependent cannot be achieved

    using QLayout. Changes are being considered (and feedback would be

    appreciated) to make layouts QStyle-able. Some of the restrictions

    involve horizontal and vertical widget alignment and widget size

    (covered below).

    \i Widget size - Mac OS X allows widgets to have specific fixed sizes.  Qt

    does not fully implement this behavior so as to maintain cross-platform

    compatibility. As a result some widgets sizes may be inappropriate (and

    subsequently not rendered correctly by the HITheme APIs).The

    QWidget::sizeHint() will return the appropriate size for many

    managed widgets (widgets enumerated in \l QStyle::ContentsType).

    \i Effects - QMacStyle uses HITheme for performing most of the drawing, but

    also uses emulation in a few cases where HITheme does not provide the

    required functionality (for example, tab bars on Panther, the toolbar

    separator, etc). We tried to make the emulation as close to the original as

    possible. Please report any issues you see in effects or non-standard

    widgets.

    \endlist

    There are other issues that need to be considered in the feel of

    your application (including the general color scheme to match the

    Aqua colors). The Guidelines mentioned above will remain current

    with new advances and design suggestions for Mac OS X.

    Note that the functions provided by QMacStyle are

    reimplementations of QStyle functions; see QStyle for their

    documentation.

    This type is used to signify a widget's focus rectangle policy.

    \value FocusDefault  show a focus rectangle when the widget has

    \obsolete

    Sets the focus rectangle policy of \a w. The \a policy can be one of

    \l{QMacStyle::FocusRectPolicy}.

    This is now simply an interface to the Qt::WA_MacShowFocusRect attribute and the

    FocusDefault value does nothing anymore. If you want to set a widget back

    to its default value, you must save the old value of the attribute before

    you change it.

    \obsolete

    Returns the focus rectangle policy for the widget \a w.

    The focus rectangle policy can be one of \l{QMacStyle::FocusRectPolicy}.

    In 4.3 and up this function will simply test for the

    Qt::WA_MacShowFocusRect attribute and will never return

    QMacStyle::FocusDefault.
