代码：
TObj1 = class(TComponent)
public
constructor Create(AOwner: TComponent;
const Parm: Integer);
destructor Destroy;
override;
end;

constructor TObj1.Create(AOwner: TComponent;
const Parm: Integer);
begin
inherited Create(AOwner);
...
end;

编译的时候出现
Method 'Create' hides virtual method of base type 'TComponent'警告信息
请问该如何去掉这个警告？

to tan_jian： override需要原形和基类一样呀？我这儿自己加了一个参数

不要叫create了，改个名，比如叫：
constructor MyCreate(AOwner: TComponent;
const Parm: Integer);
当然使用的时候要：
o:=TObj1.MyCreate(....) 了

to Pipi 就是想叫Create，为了保持统一...

覆盖了 Create ，你的 TObj1 就不能放到控件板上去了
