ContentElement.OnStylusEnter(StylusEventArgs) ContentElement.OnStylusEnter(StylusEventArgs) ContentElement.OnStylusEnter(StylusEventArgs) ContentElement.OnStylusEnter(StylusEventArgs) Method

定義

當這個項目引發未處理的 StylusEnter 附加事件時叫用。Invoked when an unhandled StylusEnter attached event is raised by this element. 實作這個方法可為此事件加入類別處理。Implement this method to add class handling for this event.

protected public:
 virtual void OnStylusEnter(System::Windows::Input::StylusEventArgs ^ e);
protected internal virtual void OnStylusEnter (System.Windows.Input.StylusEventArgs e);
abstract member OnStylusEnter : System.Windows.Input.StylusEventArgs -> unit
override this.OnStylusEnter : System.Windows.Input.StylusEventArgs -> unit
Protected Friend Overridable Sub OnStylusEnter (e As StylusEventArgs)

備註

這個方法沒有預設的實值。This method has no default implementation. 由於繼承中的中繼類別可能會實作為這個方法, 因此建議您在您的執行中呼叫基底實作為。Because an intermediate class in the inheritance might implement this method, we recommend that you call the base implementation in your implementation. 視您的需求而定, 您可以在特殊處理之前或之後呼叫基底。You may call base either before or after your special handling, depending on your requirements.

這個方法的目的類似通用語言執行平台 (CLR)common language runtime (CLR)于*方法的事件模式: 這個方法會建立類別處理常式, 而不是實例處理常式, 藉此提供從衍生類別處理相符事件的方式。The purpose of this method is similar to 通用語言執行平台 (CLR)common language runtime (CLR) event pattern On* methods: this method provides the means to handle the matching event from derived classes by establishing a class handler instead of an instance handler. 在此情況下, 比對事件是路由事件。In this case the matching event is a routed event. 將事件標示為已處理, 仍然有助於避免叫用一般實例處理常式 (未指定handledEventsToo的)。Marking the event as handled is still useful for preventing typical instance handlers (those that do not specify handledEventsToo) from being invoked.
