參數

備註

引發事件會透過委派叫用此事件處理常式。Raising an event invokes the event handler through a delegate. 如需詳細資訊，請參閱 處理和引發事件。For more information, see Handling and Raising Events.

OnParentRightToLeftChanged 方法也允許衍生類別處理事件，而不用附加委派。The OnParentRightToLeftChanged method also allows derived classes to handle the event without attaching a delegate. 這是在衍生類別中處理事件的慣用技巧。This is the preferred technique for handling the event in a derived class.

給繼承者的注意事項

當在衍生類別中覆寫 OnParentRightToLeftChanged(EventArgs) 時，請確定呼叫基底類別的 OnParentRightToLeftChanged(EventArgs) 方法，使已註冊的委派能接收到事件。When overriding OnParentRightToLeftChanged(EventArgs) in a derived class, be sure to call the base class's OnParentRightToLeftChanged(EventArgs) method so that registered delegates receive the event.
