## Detailed Description

The QMacStyle class implements an Appearance Manager style.

This class is implemented as a wrapper to the Apple Appearance Manager. This allows your application to be styled by whatever theme your Macintosh is using. This is done by having primitives in QStyle implemented in terms of what the Macintosh would normally theme (i.e. the Finder).

There are additional issues that should be taken into consideration to make an application compatible with the Aqua Style Guidelines. Some of these issues are outlined below.

- 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).
- Widget size - Aqua 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 Appearance Manager).The QWidget::sizeHint() will return the appropriate size for many managed widgets (widgets enumerated in QStyle::ContentsType).
- Effects - QMacStyle uses Appearance Manager for performing most of the drawing, but also uses emulation in a few cases where Appearance Manager does not provide the required functionality (for example, QPushButton pulsing effects). 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.

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.
