Control.IDelegateEvent<'Delegate> Interface (F#)
First class event values for arbitrary delegate types.
Namespace/Module Path: Microsoft.FSharp.Control
Assembly: FSharp.Core (in FSharp.Core.dll)
type IDelegateEvent<'Delegate> = interface abstract this.AddHandler : 'Delegate -> unit abstract this.RemoveHandler : 'Delegate -> unit end
F# gives special status to member properties compatible with type
IDelegateEvent and tagged with the
CLIEventAttribute. In this case the F# compiler generates approriate CLI metadata to make the member appear to other CLI languages as a CLI event.
|AddHandler||Connect a handler delegate object to the event. A handler can be later removed using RemoveHandler. The listener will be invoked when the event is fired.|
|RemoveHandler||Remove a listener delegate from an event listener store.|
