OnDrawImage Method

Summary

Raises the DrawImage event.

Syntax

C++

protected virtual void OnDrawImage( 
   ImageViewerSpyGlassDrawImageEventArgs e 
)

Protected Overridable Sub OnDrawImage( 
   ByVal e As ImageViewerSpyGlassDrawImageEventArgs 
)

protected:  
   virtual void OnDrawImage( 
      ImageViewerSpyGlassDrawImageEventArgs^ e 
   )

Parameters

Event data

Remarks

Raising an event invokes the event handler through a function. The OnDrawImage method also allows derived classes to handle the event without attaching a function to the event. This is the preferred technique for handling the event in a derived class.

**Note to Inheritors: **When overriding OnDrawImage in a derived class, be sure to call the base class's OnDrawImage method so that registered delegates receive the event.
