OnShowGaugeChanged Method (AnnProtractorObject)
Summary
Occurs when the value ShowGauge property changes.
Syntax
protected virtual void OnShowGaugeChanged(RoutedPropertyChangedEventArgs<bool> e)
Protected Overridable Sub OnShowGaugeChanged( _ByVal e As RoutedPropertyChangedEventArgs(Of Boolean) _)
protected:virtual void OnShowGaugeChanged(RoutedPropertyChangedEventArgs<bool>^ e)
Parameters
e
A RoutedPropertyChangedEventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate.
The OnShowGaugeChanged 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 OnShowGaugeChanged in a derived class, be sure to call the base class's OnShowGaugeChanged method so that registered delegates receive the event.
