An appointment is an activity scheduled for a specific time interval. An activity is characterized by its subject, location, category (Label), status (Status) and description. An appointment may also contain custom properties. Appointments can be recurring, which means that an activity can be scheduled to repeat at specified time intervals.
The scheduler displays an appointment as a color rectangle with text and graphics elements, as illustrated in the picture below.
An AppointmentItem object represents an appointment, and the the active View, which is used to show the Scheduler's data, determines its visual representation.
