44 | \class QMacStyle
|
---|
45 | \brief The QMacStyle class provides a Mac OS X style using the Apple Appearance Manager.
|
---|
46 |
|
---|
47 | \ingroup appearance
|
---|
48 |
|
---|
49 | This class is implemented as a wrapper to the HITheme
|
---|
50 | APIs, allowing applications to be styled according to the current
|
---|
51 | theme in use on Mac OS X. This is done by having primitives
|
---|
52 | in QStyle implemented in terms of what Mac OS X would normally theme.
|
---|
53 |
|
---|
54 | \warning This style is only available on Mac OS X because it relies on the
|
---|
55 | HITheme APIs.
|
---|
56 |
|
---|
57 | There are additional issues that should be taken
|
---|
58 | into consideration to make an application compatible with the
|
---|
59 | \link http://developer.apple.com/documentation/UserExperience/Conceptual/OSXHIGuidelines/index.html
|
---|
60 | Apple Human Interface Guidelines \endlink. Some of these issues are outlined
|
---|
61 | below.
|
---|
62 |
|
---|
63 | \list
|
---|
64 |
|
---|
65 | \i Layout - The restrictions on window layout are such that some
|
---|
66 | aspects of layout that are style-dependent cannot be achieved
|
---|
67 | using QLayout. Changes are being considered (and feedback would be
|
---|
68 | appreciated) to make layouts QStyle-able. Some of the restrictions
|
---|
69 | involve horizontal and vertical widget alignment and widget size
|
---|
70 | (covered below).
|
---|
71 |
|
---|
72 | \i Widget size - Mac OS X allows widgets to have specific fixed sizes. Qt
|
---|
73 | does not fully implement this behavior so as to maintain cross-platform
|
---|
74 | compatibility. As a result some widgets sizes may be inappropriate (and
|
---|
75 | subsequently not rendered correctly by the HITheme APIs).The
|
---|
76 | QWidget::sizeHint() will return the appropriate size for many
|
---|
77 | managed widgets (widgets enumerated in \l QStyle::ContentsType).
|
---|
78 |
|
---|
79 | \i Effects - QMacStyle uses HITheme for performing most of the drawing, but
|
---|
80 | also uses emulation in a few cases where HITheme does not provide the
|
---|
81 | required functionality (for example, tab bars on Panther, the toolbar
|
---|
82 | separator, etc). We tried to make the emulation as close to the original as
|
---|
83 | possible. Please report any issues you see in effects or non-standard
|
---|
84 | widgets.
|
---|
85 |
|
---|
86 | \endlist
|
---|
87 |
|
---|
88 | There are other issues that need to be considered in the feel of
|
---|
89 | your application (including the general color scheme to match the
|
---|
90 | Aqua colors). The Guidelines mentioned above will remain current
|
---|
91 | with new advances and design suggestions for Mac OS X.
|
---|
92 |
|
---|
93 | Note that the functions provided by QMacStyle are
|
---|
94 | reimplementations of QStyle functions; see QStyle for their
|
---|
95 | documentation.
