OnInteractiveRegionFreehand Method

Summary

Raises the InteractiveRegionFreehand event.

Syntax

C++/CLI

C++

protected virtual void OnInteractiveRegionFreehand( 
   RasterViewerPointsEventArgs e 
)

protected: 
virtual void OnInteractiveRegionFreehand(  
   RasterViewerPointsEventArgs^ 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.
