When we create a component as a custom control and the control is dropped on a panel the control always appears on the form rather than the containing control. How do you set the parent of the custom control in Create so that when the button is dropped on panel the buttons parent is the panel?

TGlassButton = class(TCustomControl)
...
public
    { Public declarations }
    constructor Create(AOwner: TComponent); override;
...

constructor TGlassButton.Create(AOwner: TComponent);
  begin
    inherited;  ???????????
    inherited Create(AOwner); ????????????
    Parent := TWinControl( AComponent ); ??????????????
    ...
  end;

The problem is designtime creation not runtime. This works perfectly:

procedure TForm10.FormCreate(Sender: TObject);
begin
  GlassButton0 := TGlassButton.Create( Panel1 );
  GlassButton0.Parent := Panel1;
  GlassButton0.Left := 20;
  GlassButton0.Top := 6;
  GlassButton0.Width := 150;
  GlassButton0.Height := 25;
  GlassButton0.Caption := 'Created At RunTime';
end;
