備註

變更所使用的字型 ContainerControl ,會導致配置重新計算,並在屬性的值為時重新套用至包含的控制項 AutoScaleMode FontChanging the font used by a ContainerControl will cause the layout to be recalculated and reapplied to the contained controls if the AutoScaleMode property has a value of Font.

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 方法也允許衍生類別處理事件,而不用附加委派。The OnFontChanged 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

OnFontChanged(EventArgs)在衍生類別中覆寫時,請務必呼叫基類的方法, OnFontChanged(EventArgs) 讓已註冊的委派能接收事件。When overriding OnFontChanged(EventArgs) in a derived class, be sure to call the base class' OnFontChanged(EventArgs) method so that registered delegates receive the event.
