我增加一点，inprise公司有个控件MenuBar.pas可以直接放在coolbar上，再添加
MainMenu，设置MenuBar的Menu为MainMenu,form1的menu为空，就可以做出Delphi
一样的菜单，不过要想更好的效果，建议使用AM2000,
MenuBar.pas 源码如下:
{*******************************************************}

{ Implements a TToolbar descendant that has a Menu to }
{ make IDE like Toolbar menus very easy. This works }
