Apple events are identified by their event class and event ID attributes. The event ID is the attribute that identifies the particular Apple event within its event class. In conjunction with the event class, the event ID uniquely identifies the Apple event and communicates what action the Apple event should perform. The event ID appears in the
where field of the event record for an Apple event. For example, an event with ID
k and class
k is an event sent by the Mac OS that launches an application.
Only a small number of event IDs are shown here. For a more complete listing, see the Apple Event Manager and Open Scripting Architecture header files.
