\class QMacStyle
\brief The QMacStyle class provides a \macos style using the Apple Appearance Manager.
\ingroup appearance
\inmodule QtWidgets
\internal
This class is implemented as a wrapper to the HITheme
APIs, allowing applications to be styled according to the current
theme in use on \macos. This is done by having primitives
in QStyle implemented in terms of what \macos would normally theme.
\warning This style is only available on \macos because it relies on the
HITheme APIs.
There are additional issues that should be taken
into consideration to make an application compatible with the
\l{Apple Human Interface Guidelines}{Apple Human Interface Guidelines}. Some of these issues are outlined
below.
\list
\li 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).
\li Widget size - \macos 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).
\li 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 \macos.
Note that the functions provided by QMacStyle are
reimplementations of QStyle functions; see QStyle for their
documentation.
