COM组件IMPORT后，在程序中可以列出方法但是无法列出事件

Question

一个COM组件，引入DELPHI后，得到了TLB文件，
然后我这样创建这个COM组件：procedure TForm1.Button1Click(Sender: TObject);
var
  test: ITESTCOM;
begin  test := CoTESTCOM.Create;
  test.start();
end;然后我写了一个事件，想这样：test.success := OnMySuccess();结果提示 ITESTCOMM没有 success 这个member.我输入 test. 后，DELPHI的IDE自动列出了所有的METHOD，但是没有列出EVENT，请问我哪里搞错了？谢谢
