ScrollableControl.OnPaddingChanged(EventArgs) 方法

定义

命名空间:
System.Windows.Forms
程序集:
System.Windows.Forms.dll

引发 PaddingChanged 事件。Raises the PaddingChanged event.

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

参数

e
EventArgs

包含事件数据的 EventArgs。An EventArgs that contains the event data.

注解

引发事件时，将通过委托调用事件处理程序。Raising an event invokes the event handler through a delegate. 有关详细信息，请参阅 处理和引发事件。For more information, see Handling and Raising Events.

OnPaddingChanged 方法还允许派生类对事件进行处理而不必附加委托。The OnPaddingChanged method also allows derived classes to handle the event without attaching a delegate. 这是在派生类中处理事件的首选技术。This is the preferred technique for handling the event in a derived class.

继承者说明

当 OnPaddingChanged(EventArgs) 在派生类中重写时，请确保调用基类的 OnPaddingChanged(EventArgs) 方法，以便注册的委托接收事件。When overriding OnPaddingChanged(EventArgs) in a derived class, be sure to call the base class' OnPaddingChanged(EventArgs) method so that registered delegates receive the event.
