OnInteractiveUserRectangle Method

protected virtual void OnInteractiveUserRectangle( 
   RasterViewerRectangleEventArgs e
)

'Declaration
 
Protected Overridable Sub OnInteractiveUserRectangle( _
   ByVal e As RasterViewerRectangleEventArgs _
) 

'Usage
 
Dim instance As RasterImageViewer
Dim e As RasterViewerRectangleEventArgs
 
instance.OnInteractiveUserRectangle(e)

protected:
virtual void OnInteractiveUserRectangle( 
   RasterViewerRectangleEventArgs^ e
) 

Parameters

e

A RasterViewerRectangleEventArgs object that contains the event data.

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