TatEventDispatcher Class

Handles the routing of a specific Delphi event to a script routine.

Remarks

When the event broker assigns a script routine to a Delphi event, it creates a TatEventDispatcher to intercept that event and forward execution to the specified routine. Dispatchers are created and destroyed automatically by the scripter when events are set or unset.

Syntax

Unit: atScript

TatEventDispatcher = class(TCollectionItem);
