override this.OnRegionChanged : EventArgs -> unit
Protected Overridable Sub OnRegionChanged (e As EventArgs)

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnRegionChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnRegionChanged(EventArgs) in a derived class, be sure to call the base class's OnRegionChanged(EventArgs) method so that registered delegates receive the event.
