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.

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

繼承類別應該覆寫此方法以處理 Windows 要求来清除的背景。Inheriting classes should override this method to handle the Windows request to erase the background.
