| 30 | \class QMacStyle | 
|---|
| 31 | \brief The QMacStyle class provides a Mac OS X style using the Apple Appearance Manager. | 
|---|
| 32 |  | 
|---|
| 33 | \ingroup appearance | 
|---|
| 34 |  | 
|---|
| 35 | This class is implemented as a wrapper to the HITheme | 
|---|
| 36 | APIs, allowing applications to be styled according to the current | 
|---|
| 37 | theme in use on Mac OS X. This is done by having primitives | 
|---|
| 38 | in QStyle implemented in terms of what Mac OS X would normally theme. | 
|---|
| 39 |  | 
|---|
| 40 | \warning This style is only available on Mac OS X because it relies on the | 
|---|
| 41 | HITheme APIs. | 
|---|
| 42 |  | 
|---|
| 43 | There are additional issues that should be taken | 
|---|
| 44 | into consideration to make an application compatible with the | 
|---|
| 45 | \link http://developer.apple.com/documentation/UserExperience/Conceptual/OSXHIGuidelines/index.html | 
|---|
| 46 | Apple Human Interface Guidelines \endlink. Some of these issues are outlined | 
|---|
| 47 | below. | 
|---|
| 48 |  | 
|---|
| 49 | \list | 
|---|
| 50 |  | 
|---|
| 51 | \i Layout - The restrictions on window layout are such that some | 
|---|
| 52 | aspects of layout that are style-dependent cannot be achieved | 
|---|
| 53 | using QLayout. Changes are being considered (and feedback would be | 
|---|
| 54 | appreciated) to make layouts QStyle-able. Some of the restrictions | 
|---|
| 55 | involve horizontal and vertical widget alignment and widget size | 
|---|
| 56 | (covered below). | 
|---|
| 57 |  | 
|---|
| 58 | \i Widget size - Mac OS X allows widgets to have specific fixed sizes.  Qt | 
|---|
| 59 | does not fully implement this behavior so as to maintain cross-platform | 
|---|
| 60 | compatibility. As a result some widgets sizes may be inappropriate (and | 
|---|
| 61 | subsequently not rendered correctly by the HITheme APIs).The | 
|---|
| 62 | QWidget::sizeHint() will return the appropriate size for many | 
|---|
| 63 | managed widgets (widgets enumerated in \l QStyle::ContentsType). | 
|---|
| 64 |  | 
|---|
| 65 | \i Effects - QMacStyle uses HITheme for performing most of the drawing, but | 
|---|
| 66 | also uses emulation in a few cases where HITheme does not provide the | 
|---|
| 67 | required functionality (for example, tab bars on Panther, the toolbar | 
|---|
| 68 | separator, etc). We tried to make the emulation as close to the original as | 
|---|
| 69 | possible. Please report any issues you see in effects or non-standard | 
|---|
| 70 | widgets. | 
|---|
| 71 |  | 
|---|
| 72 | \endlist | 
|---|
| 73 |  | 
|---|
| 74 | There are other issues that need to be considered in the feel of | 
|---|
| 75 | your application (including the general color scheme to match the | 
|---|
| 76 | Aqua colors). The Guidelines mentioned above will remain current | 
|---|
| 77 | with new advances and design suggestions for Mac OS X. | 
|---|
| 78 |  | 
|---|
| 79 | Note that the functions provided by QMacStyle are | 
|---|
| 80 | reimplementations of QStyle functions; see QStyle for their | 
|---|
| 81 | documentation. |
