OnInteractiveZoomTo Method

protected virtual void OnInteractiveZoomTo( 
   RectangleInteractiveEventArgs e
)

'Declaration
 
Protected Overridable Sub OnInteractiveZoomTo( _
   ByVal e As RectangleInteractiveEventArgs _
) 

'Usage
 
Dim instance As ImageViewer
Dim e As RectangleInteractiveEventArgs
 
instance.OnInteractiveZoomTo(e)

protected:
virtual void OnInteractiveZoomTo( 
   RectangleInteractiveEventArgs^ e
) 

Parameters

e

A RectangleInteractiveEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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