Component Doesn't Display When Created Dynamically - Delphi Newbie

Hi, created a new component using Delphi 6 which won't display when i call it at run time although it is being created, at least it appears to be when i debug it. Therefore Decided to recreate its class on a blank form and to try and display it when i clicked the form to remove the possibility that it was other code interfering. The object still doesn't appear. i know i`m missing something simple but being new to delphi can't figure it out! Heres my code:


unit TestTimePeriod;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ExtCtrls,Menus;
type
  TForm1 = class(TForm)
    procedure FormClick(Sender: TObject);
    private
      { Private declarations }
    public
      { Public declarations }
  end;

  TIBTTimePeriodRect = class(TShape)
    private
      //Variables
      startTime: Integer;
      endTime: Integer;
      timeCode: string;



    protected

    public
      //Variables

      //Methods
      constructor create(AOwner: TComponent); override;

    published
  end;



var
  Form1: TForm1;

implementation

{$R *.dfm}

  //TIBTTimePeriodRect's Constructor & Destructor
  constructor TIBTTimePeriodRect.create(AOwner: TComponent);
  Begin
    inherited create(AOwner);

    startTime:=0;
    endTime:=0;
    timeCode:='';

  end;




procedure TForm1.FormClick(Sender: TObject);
var
  TP:TIBTTimePeriodRect;
begin

  TP:=TIBTTimePeriodRect.create(self);


  tp.Left:=10;
  tp.width:=100;
  tp.top:=10;
  tp.Height:=25;

  tp.Brush.Color:=clWhite;
  tp.Visible:=true;


  ShowMessage('TimePeriod should be visible');

end;

end.


Do i need to assign the object to the form? Is it something to do with the fact it is a subclass of TShape?

I`ll be Grateful for any help, thanks in advance,

Mick
