\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.
