OnRectChanged Method (AnnRectangleObject)

protected virtual void OnRectChanged( 
   RoutedPropertyChangedEventArgs<Rect> e
)

'Declaration
 
Protected Overridable Sub OnRectChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Rect) _
) 

'Usage
 
Dim instance As AnnRectangleObject
Dim e As RoutedPropertyChangedEventArgs(Of Rect)
 
instance.OnRectChanged(e)

protected:
virtual void OnRectChanged( 
   RoutedPropertyChangedEventArgs<Rect>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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