TObject constructor Create; 并不是virtual; 派生类 怎么可以 override; 呢？(200分)

TObject constructor Create
并不是virtual
派生类 怎么可以 override
呢？
这是怎么回事？
TObject = class
constructor Create;
destructor Destroy
virtual;

TPersistent = class(TObject)
public
destructor Destroy
override;

TControl = class(TComponent)
public
constructor Create(AOwner: TComponent)
override;
destructor Destroy
override;

TScrollingWinControl = class(TWinControl)
public
constructor Create(AOwner: TComponent)
override;
destructor Destroy
override;

TComponent的CREATE就是virtual的

看看vcl代码你就知道了
