protected override void OnSizeChanged( 
   EventArgs e
)

'Declaration
 
Protected Overrides Sub OnSizeChanged( _
   ByVal e As EventArgs _
)

'Usage
 
Dim instance As RasterImagePanViewer
Dim e As EventArgs
 
instance.OnSizeChanged(e)

protected override void OnSizeChanged( 
   ~Remove~ e
)

 function Leadtools.WinForms.RasterImagePanViewer.OnSizeChanged( 
   e 
)

protected:
void OnSizeChanged( 
   EventArgs^ e
) override

Parameters

e: An System.EventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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