OnImageRectangleChanged Method

Summary

Syntax

C++

protected virtual void OnImageRectangleChanged( 
   EventArgs e 
)

  
Protected Overridable Sub OnImageRectangleChanged( _ 
   ByVal e As EventArgs _ 
)

protected: 
virtual void OnImageRectangleChanged(  
   EventArgs^ e 
)

Parameters

e
An System.EventArgs that contains the event data.

Remarks

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

Example

For an example, refer to RasterImagePrinter and ImageRectangle.
