Leadtools.Windows.Annotations Namespace > AnnObject Class : OnHeaderOffsetChanged Method |
protected virtual void OnHeaderOffsetChanged( RoutedPropertyChangedEventArgs<Point> e )
'Declaration Protected Overridable Sub OnHeaderOffsetChanged( _ ByVal e As RoutedPropertyChangedEventArgs(Of Point) _ )
'Usage Dim instance As AnnObject Dim e As RoutedPropertyChangedEventArgs(Of Point) instance.OnHeaderOffsetChanged(e)
protected: virtual void OnHeaderOffsetChanged( RoutedPropertyChangedEventArgs<Point>^ e )
Raising an event invokes the event handler through a delegate.
The OnHeaderOffsetChanged 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 OnHeaderOffsetChanged in a derived class, be sure to call the base class's OnHeaderOffsetChanged method so that registered delegates receive the event.
