IconFamily 'icns' resources contain an entire IconFamily (all sizes and depths).
|
|
For custom icons, icns IconFamily resources of the custom icon resource ID are fetched first before
|
|
the classic custom icons (individual 'ics#, ICN#, etc) are fetched. If the fetch of the icns resource
|
|
succeeds then the icns is looked at exclusively for the icon data.
|
|
For custom icons, new icon features such as 32-bit deep icons are only fetched from the icns resource.
|
|
This is to avoid incompatibilities with cut & paste of new style icons with an older version of the
|
|
MacOS Finder.
|
|
DriverGestalt is called with code kdgMediaIconSuite by IconServices after calling FSM to determine a
|
|
driver icon for a particular device. The result of the kdgMediaIconSuite call to DriverGestalt should
|
|
be a pointer an an IconFamily. In this manner driver vendors can provide rich, detailed drive icons
|
|
instead of the 1-bit variety previously supported.
