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