Параметры

eventName
The name of the event to raise.

eventText
The text describing the event.

arguments
An array of arguments to pass to the event.

subComponent
A String that contains more detail about the event source.

fireAgain
A Boolean that indicates this should continue firing or stop firing. A value of true indicates that it should continue firing.

Замечания

Because firing of an event may be expensive, the run-time engine provides a mechanism for suppressing events that you are not interested in. Every event firing method has a FireAgain parameter. If the value of this variable is false, then after the method returns, the caller will not fire this event again for the duration of the current execution.

Several of the events have a subComponent parameter that allows for even greater granularity in event source identification.
