 virtual void OnRenderItemCheck(System::Windows::Forms::ToolStripItemImageRenderEventArgs ^ e);
protected virtual void OnRenderItemCheck (System.Windows.Forms.ToolStripItemImageRenderEventArgs e);
abstract member OnRenderItemCheck : System.Windows.Forms.ToolStripItemImageRenderEventArgs -> unit

參數

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.

OnRenderItemCheck 方法也允許衍生類別處理事件,而不用附加委派。The OnRenderItemCheck 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 OnRenderItemCheck(ToolStripItemImageRenderEventArgs) 時,請確定呼叫基底類別的 OnRenderItemCheck(ToolStripItemImageRenderEventArgs) 方法,使已註冊的委派能接收到事件。When overriding OnRenderItemCheck(ToolStripItemImageRenderEventArgs) in a derived class, be sure to call the base class's OnRenderItemCheck(ToolStripItemImageRenderEventArgs) method so that registered delegates receive the event.
