OnInteractiveCenterAt Method

protected virtual void OnInteractiveCenterAt( 
   PointInteractiveEventArgs e
)

protected:
virtual void OnInteractiveCenterAt( 
   PointInteractiveEventArgs^ e
) 

'Declaration
 
Protected Overridable Sub OnInteractiveCenterAt( _
   ByVal e As PointInteractiveEventArgs _
) 

'Usage
 
Dim instance As ImageViewer
Dim e As PointInteractiveEventArgs
 
instance.OnInteractiveCenterAt(e)

Parameters

e

A PointInteractiveEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

The OnInteractiveCenterAt 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 OnInteractiveCenterAt in a derived class, be sure to call the base class's OnInteractiveCenterAt method so that registered delegates receive the event.
