Control.OnResize(EventArgs) 方法

定义

引发 Resize 事件。Raises the Resize event.

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

参数

e
EventArgs

包含事件数据的 EventArgsAn 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.

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

继承者说明

在派生类中重写 OnResize(EventArgs) 时,一定要调用基类的 OnResize(EventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnResize(EventArgs) in a derived class, be sure to call the base class's OnResize(EventArgs) method so that registered delegates receive the event. 可以在构造过程中调用 OnResize(EventArgs) 方法,因此,如果重写 OnResize(EventArgs),则可以在调用控制构造函数之前调用此方法。The OnResize(EventArgs) method can be called during construction, so if you override OnResize(EventArgs) it can be called before the control constructor is called.
