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