protected virtual void OnInteractiveRegionFreehand( 
   RasterViewerPointsEventArgs e
)

'Declaration
 
Protected Overridable Sub OnInteractiveRegionFreehand( _
   ByVal e As RasterViewerPointsEventArgs _
)

'Usage
 
Dim instance As RasterImageViewer
Dim e As RasterViewerPointsEventArgs
 
instance.OnInteractiveRegionFreehand(e)

protected:
virtual void OnInteractiveRegionFreehand( 
   RasterViewerPointsEventArgs^ e
)

Parameters

e: A RasterViewerPointsEventArgs that contains the event data.

Remarks

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