OnItemForeColorChanged Method

Summary

Syntax

C++/CLI

C++

protected virtual void OnItemForeColorChanged( 
   EventArgs e 
)

protected: 
virtual void OnItemForeColorChanged(  
   EventArgs^ e 
)

protected:  
   virtual void OnItemForeColorChanged( 
      EventArgs^ e 
   )

Parameters

e
An System.EventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

The OnItemForeColorChanged 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 OnItemForeColorChanged in a derived class, be sure to call the base class's OnItemForeColorChanged method so that registered delegates receive the event.

Example

This example overrides the virtual events of the RasterImageList class.

using Leadtools.WinForms; 
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
 
public class MyRasterImageList : RasterImageList 
{ 
   //. 
   //. 
   //.
