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