Komponentenentwicklung LED über TShape ?

[Chris211183]

Ich wollte mal meine Komponente Testen, jedoch wird nix dsrgestellt

Delphi-Quellcode:

unit LedUnit;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ExtCtrls, StdCtrls;

type
    TLED = class(TGraphicControl)
    //HoyLed: TShape;


  private
  { Private declarations }
  FActive: Boolean;
  procedure SetActive(const Value: Boolean);

  protected
  { Protected declarations }

  public
  { Public declarations }

  published
  { Published declarations }
     property Active: Boolean read FActive write SetActive;

end;


var                                    
  LED: TLED;
  Shape : TShape;
  Brush: TShape;
  Color: TColor;
  ShowHint: Boolean;




implementation

{$R *.dfm}


procedure  TLED.SetActive(const Value: Boolean);
begin
if Active <> FActive then
   begin
   FActive := Active;
   invalidate;
end;



begin
    Shape := TShape.Create(LED);


 with Shape do
 begin
 Left := 30;
 Top := 30;
 Width := 30;

end;
  end;
    end;


type
        TTriangleShape = class(TShape)

        private
        { Private declarations }

        protected
        { Protected declarations }
          procedure Paint; override;

        public
        { Public declarations }
        published
        { Published declarations }
end;


type
        TPointArray = array [0..2] of TPoint;
        PPointArray = ^TPointArray;

        procedure TTriangleShape.Paint;


begin
with Canvas do
        begin
        Polygon([Point(0, (Self.Height-2)), Point((Self.Width div 2), 0),
        Point(Self.Width, (Self.Height-2)), Point(0, (Self.Height-2))]);
        end;
           end;

jemand ne Ahnung warum nichts beim Test während der Laufzeit auf meinem Formular zu sehen ist ?? Ich langsam nicht mehr
