定義

引發 PaddingChanged 事件。Raises the PaddingChanged event.

protected:
 virtual void OnPaddingChanged(EventArgs ^ e);
protected virtual void OnPaddingChanged (EventArgs e);
abstract member OnPaddingChanged : EventArgs -> unit
override this.OnPaddingChanged : EventArgs -> unit
Protected Overridable Sub OnPaddingChanged (e As EventArgs)

參數

e
EventArgs EventArgs EventArgs EventArgs

EventArgs,其中包含事件資料。A 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.

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