Control.OnLayout(LayoutEventArgs) Control.OnLayout(LayoutEventArgs) Control.OnLayout(LayoutEventArgs) Control.OnLayout(LayoutEventArgs) Method

定義

引發 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)

參數

levent
LayoutEventArgs LayoutEventArgs LayoutEventArgs LayoutEventArgs

LayoutEventArgs,其中包含事件資料。A LayoutEventArgs 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.

OnLayout 方法也允許衍生類別處理事件,而不用附加委派。The OnLayout 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

在衍生OnLayout(LayoutEventArgs)類別中覆寫時,請務必呼叫基類的OnLayout(LayoutEventArgs)方法,讓已註冊的委派能接收事件,並讓一般的停駐和錨定函式運作。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. 衍生類別應該覆寫此方法,以執行任何自訂的版面配置邏輯。Derived classes should override this method to do any custom layout logic.
