Control.OnLayout(LayoutEventArgs) 方法

定义

引发 Layout 事件。Raises the Layout event.

protected:
 virtual void OnLayout(System::Windows::Forms::LayoutEventArgs ^ levent);
protected virtual void OnLayout (System.Windows.Forms.LayoutEventArgs levent);
abstract member OnLayout : System.Windows.Forms.LayoutEventArgs -> unit
override this.OnLayout : System.Windows.Forms.LayoutEventArgs -> unit
Protected Overridable Sub OnLayout (levent As LayoutEventArgs)

参数

levent
LayoutEventArgs

包含事件数据的 LayoutEventArgsA LayoutEventArgs 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.

OnLayout 方法还允许派生类对事件进行处理而不必附加委托。The OnLayout 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

当在派生类中重写 OnLayout(LayoutEventArgs) 时,请确保调用基类的 OnLayout(LayoutEventArgs) 方法,以便已注册的委托接收事件,并使典型的停靠和锚定函数正常运行。When overriding OnLayout(LayoutEventArgs) in a derived class, be sure to call the base class's OnLayout(LayoutEventArgs) method so that registered delegates receive the event and for typical docking and anchoring functions to work. 派生类应重写此方法,以执行任何自定义布局逻辑。Derived classes should override this method to do any custom layout logic.
