I have reintroduced the form constructor in a base form, but if I override the original constructor in a descendant form, the reintroduced constructor is no longer visible.

type
  TfrmA = class(TForm)
  private
    FWndParent: HWnd;
  public
    constructor Create(AOwner: TComponent; const AWndParent: Hwnd); reintroduce; overload; virtual;
  end;

constructor TfrmA.Create(AOwner: TComponent; const AWndParent: Hwnd);
begin
  FWndParent := AWndParent;
  inherited Create(AOwner);
end;

type
  TfrmB = class(TfrmA)
  private
  public
  end;

type
  TfrmC = class(TfrmB)
  private
  public
    constructor Create(AOwner: TComponent); override;
  end;

constructor TfrmC.Create(AOwner: TComponent);
begin
  inherited Create(AOwner);
end;

When creating:

  frmA := TfrmA.Create(nil, 0);
  frmB := TfrmB.Create(nil, 0);
  frmC := TfrmC.Create(nil, 0); // Compiler error

My work-around is to override the reintroduced constructor or to declare the original constructor overloaded, but I'd like to understand the reason for this behavior.

type
  TfrmA = class(TForm)
  private
    FWndParent: HWnd;
  public
    constructor Create(AOwner: TComponent); overload; override;
    constructor Create(AOwner: TComponent; const AWndParent: Hwnd); reintroduce; overload; virtual;
  end;

type
  TfrmC = class(TfrmB)
  private
  public
    constructor Create(AOwner: TComponent; const AWndParent: Hwnd); override;
  end;
