窗体上方 MainMenu 怎样改变颜色(100分)

我已经实现 下拉菜单 颜色的改变
但窗体上的那一行不行，
大家看看，跟点方法
恩

设置主菜单的 OwnerDraw 为 true
在菜单条的菜单项的OnDrawItem 中进行如下处理：

procedure TForm1.aaa1DrawItem(Sender: TObject; ACanvas: TCanvas;
ARect: TRect; Selected: Boolean);
begin
if selected then ACanvas.brush.color:=$0000ff
else ACanvas.brush.color:=$00ffff;
ACanvas.font.color:=$ffffff;
ACanvas.TextOut(ARect.Left ,ARect.Top,TMenuItem(Sender).caption );
end;

去找一个Xmenu控件吧，做xp式的菜单特爽！

xpmenu

to jsxjd 但窗体上的那一行不行，
你那样只能 下拉菜单 颜色的改变
再想想办法，谢谢。

jsxjd　的思路是对的。
在ACanvas上，你可以任意处理，为什么要局限于ARect呢？
我做过这样的程序

关注！

可以跟一个你的例子吗？

我做的就是“菜单条”中的菜单项。
