C#
Visual Basic
Objective-C
Java
C++

protected virtual void OnInteractiveZoomAt( 
   RasterViewerPointEventArgs e
)

'Declaration
 
Protected Overridable Sub OnInteractiveZoomAt( _
   ByVal e As RasterViewerPointEventArgs _
)

'Usage
 
Dim instance As RasterImageViewer
Dim e As RasterViewerPointEventArgs
 
instance.OnInteractiveZoomAt(e)

protected:
virtual void OnInteractiveZoomAt( 
   RasterViewerPointEventArgs^ e
)

Parameters

e: A RasterViewerPointEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. The OnInteractiveZoomAt 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 OnInteractiveZoomAt in a derived class, be sure to call the base class's OnInteractiveZoomAt method so that registered delegates receive the event.
