OnGeometryChanged Method

protected virtual void OnGeometryChanged( 
   RoutedPropertyChangedEventArgs<Geometry> e
)

'Declaration
 
Protected Overridable Sub OnGeometryChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Geometry) _
) 

'Usage
 
Dim instance As ImageViewer
Dim e As RoutedPropertyChangedEventArgs(Of Geometry)
 
instance.OnGeometryChanged(e)

protected:
virtual void OnGeometryChanged( 
   RoutedPropertyChangedEventArgs<Geometry^>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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