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. \img qmacstyle.png \sa QWindowsXPStyle, QWindowsStyle, QPlastiqueStyle, QCDEStyle, QMotifStyle */ /*! \enum QMacStyle::WidgetSizePolicy \value SizeSmall \value SizeLarge \value SizeMini \value SizeDefault \omitvalue SizeNone */ /*! \fn QMacStyle::QMacStyle() Constructs a QMacStyle object. */ /*! \fn QMacStyle::~QMacStyle() Destructs a QMacStyle object. */ /*! \fn void QMacStyle::polish(QPalette &pal) \reimp */ /*! \fn void QMacStyle::polish(QApplication *) \reimp */ /*! \fn void QMacStyle::unpolish(QApplication *) \reimp */ /*! \fn void QMacStyle::polish(QWidget* w) \reimp */ /*! \fn void QMacStyle::unpolish(QWidget* w) \reimp */ /*! \fn int QMacStyle::pixelMetric(PixelMetric metric, const QStyleOption *opt, const QWidget *widget) const \reimp */ /*! \fn QPalette QMacStyle::standardPalette() const \reimp */ /*! \fn int QMacStyle::styleHint(StyleHint sh, const QStyleOption *opt, const QWidget *w, QStyleHintReturn *hret) const \reimp */ /*! \fn QPixmap QMacStyle::generatedIconPixmap(QIcon::Mode iconMode, const QPixmap &pixmap, const QStyleOption *opt) const \reimp */ /*! \fn QPixmap QMacStyle::standardPixmap(StandardPixmap standardPixmap, const QStyleOption *opt, const QWidget *widget) const \reimp */ /*! \enum QMacStyle::FocusRectPolicy This type is used to signify a widget's focus rectangle policy. \value FocusEnabled show a focus rectangle when the widget has focus. \value FocusDisabled never show a focus rectangle for the widget. \value FocusDefault show a focus rectangle when the widget has focus and the widget is a QSpinWidget, QDateTimeEdit, QLineEdit, QListBox, QListView, editable QTextEdit, or one of their subclasses. */ /*! \fn void QMacStyle::setFocusRectPolicy(QWidget *w, FocusRectPolicy policy) \obsolete Sets the focus rectangle policy of \a w.
