The Apple event data type describes a full-fledged Apple event.
Like the data for an Apple event record (data type
AERecord), the data for an Apple event
consists of a list of keyword-specified descriptors. Unlike an Apple
event record, the data for an Apple event is conceptually divided
into two parts, one for attributes and one for parameters. This division
within the Apple event allows the Apple Event Manager to distinguish
between an event’s attributes and its parameters.
For additional information on the structure of an Apple event and on how to build one, see Building an Apple Event in Apple Events Programming Guide.
