定義

引發 FontChanged 事件。Raises the FontChanged event.

protected:
 override void OnFontChanged(EventArgs ^ e);
protected override void OnFontChanged (EventArgs e);
override this.OnFontChanged : EventArgs -> unit
Protected Overrides Sub OnFontChanged (e As EventArgs)

參數

e
EventArgs

包含事件資料的 EventArgsAn EventArgs that contains the event data.

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.

OnFontChanged方法也可讓衍生類別處理事件,而不需要附加委派。The OnFontChanged method also enables 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 OnFontChanged(EventArgs) 時,請確定呼叫基底類別的 OnFontChanged(EventArgs) 方法,使已註冊的委派能接收到事件。When overriding OnFontChanged(EventArgs) in a derived class, be sure to call the base class's OnFontChanged(EventArgs) method so that registered delegates receive the event.
