Syntax

   RoutedPropertyChangedEventArgs<double> e
)
'Declaration
 
Protected Overridable Sub OnScaleFactorChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Double) _
) 
'Usage
 
Dim instance As MagnifyGlass
Dim e As RoutedPropertyChangedEventArgs(Of Double)
 
instance.OnScaleFactorChanged(e)

            

            
protected:
virtual void OnScaleFactorChanged( 
   RoutedPropertyChangedEventArgs<double>^ e
) 

Parameters

e
A RoutedPropertyChangedEventArgs 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.
