C++

protected virtual void OnScaleFactorChanged( 
   EventArgs e
)

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

'Usage
 
Dim instance As RasterImageViewer
Dim e As EventArgs
 
instance.OnScaleFactorChanged(e)

protected:
virtual void OnScaleFactorChanged( 
   EventArgs^ e
)

Parameters

e: An EventArgs that contains the event data.

Remarks

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