   EventArgs e
)

'Declaration
 
Protected Overridable Sub OnLoadingThumbnailChanged( _
   ByVal e As EventArgs _
) 

'Usage
 
Dim instance As RasterThumbnailBrowser
Dim e As EventArgs
 
instance.OnLoadingThumbnailChanged(e)

protected:
virtual void OnLoadingThumbnailChanged( 
   EventArgs^ e
) 

Parameters

e

An System.EventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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