ToolStrip.OnLayout(LayoutEventArgs) ToolStrip.OnLayout(LayoutEventArgs) ToolStrip.OnLayout(LayoutEventArgs) ToolStrip.OnLayout(LayoutEventArgs) Method

定義

引發 Layout 事件。Raises the Layout event.

protected:
 override void OnLayout(System::Windows::Forms::LayoutEventArgs ^ e);
protected override void OnLayout (System.Windows.Forms.LayoutEventArgs e);
override this.OnLayout : System.Windows.Forms.LayoutEventArgs -> unit
Protected Overrides Sub OnLayout (e As LayoutEventArgs)

參數

e
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

當在衍生類別中覆寫 OnLayout(LayoutEventArgs) 時,請確定呼叫基底類別的 OnLayout(LayoutEventArgs) 方法,使已註冊的委派能接收到事件。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.
