| 这是以前写的代码，自绘XP风格的菜单，硬盘坏了后以为没了，最后写的一个软件要自定义风格，“翻箱倒柜”的终于在我可爱的古董机^_^上找到了一个应用的例子。 把主菜单作以下调整：
OnMeasureItem指向MeasureMainItem、
OnAdvancedDrawItem指向DrawMainItem，
子菜单的OnMeasureItem指向MeasureSubItem、
OnAdvancedDrawItem指向DrawSubItem，
调整颜色或使用默认颜色即可达到效果
| //调整主菜单项尺寸
procedure MeasureMainItem(Sender: TObject; ACanvas: TCanvas; var Width, Height: Integer);
begin
Width := Width + 6;
Height := Height + 2;
end; //调整子菜单项尺寸
procedure MeasureSubItem(Sender: TObject; ACanvas: TCanvas; var Width, Height: Integer);
begin
Width := Width + 20;
Height := Height + 2;
end; //绘制主菜单内容
procedure DrawMainItem(Sender: TObject; ACanvas: TCanvas; ARect: TRect; State: TOwnerDrawState);
