Constant descriptions

gestaltDisplayMgrAttr

The Gestalt selector you pass to determine which Display Manager attributes are present.

gestaltDisplayMgrPresent

If true, the Display Manager is present.

gestaltDisplayMgrCanSwitchMirrored

If true, the Display Manager can switch modes on mirrored displays.

gestaltDisplayMgrSetDepthNotifies

If true, and you have registered for notification and you will be notified of depth mode changes.

gestaltDisplayMgrCanConfirm

Not yet supported. Most commonly comes up for display modes that are not marked kModeSafe. There is currently no system support for trying an unsafe mode and then restoring if the user does not confirm. When this is supported, this bit will be set.

gestaltDisplayMgrColorSyncAware

If true, Display Manager supports profiles for displays.

gestaltDisplayMgrGeneratesProfiles

Before calling any function dependent upon the Display Manager, your application should pass the selector gestaltDisplayMgrAttr to the Gestalt function to determine the Display Manager attributes that are present.
