end;end.
请问高手 为什么我执行了这段程序没有出现动画效果 请指教 谢谢.

Answer 1

animatedisplay(1,2000);
这句调用应该放在Form的OnCreate事件里

Answer 2

animatewindow函数是用在窗体显示的时候的你的窗体已经show出来了，还怎么出现动画？再加个窗体就可以看到了
procedure animatedisplay(mode:short;delaytime:integer);
begin
  case mode of
    1:animatewindow(form2.Handle,delaytime,aw_blend or aw_activate);
    2:animatewindow(form2.Handle,delaytime,aw_center or aw_activate);
    3:animatewindow(form2.Handle,delaytime,aw_ver_negative or aw_activate);
    4:animatewindow(form2.Handle,delaytime,aw_ver_positive or aw_activate);
    end;end;
procedure TForm1.Button1Click(Sender: TObject);
begin
  animatedisplay(1,2000);
end;
