Control.OnStyleChanged(EventArgs) Method


引发 StyleChanged 事件。Raises the StyleChanged event.

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



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


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.

利用 OnStyleChanged 方法,派生类还可以处理事件,而无需附加委托。The OnStyleChanged method also enables 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.

Notes to Inheritors

在派生类中重写 OnStyleChanged(EventArgs) 时,一定要调用基类的 OnStyleChanged(EventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnStyleChanged(EventArgs) in a derived class, be sure to call the base class's OnStyleChanged(EventArgs) method so that registered delegates receive the event.
