Label with Lines Property

Anyone know where I can get a label component that has a Lines property ? (ie. ability to load text from a file or have text longer then 256 characters.) Already looked at torrys but nothing there.

Plz do not suggest a memo or richedit control unless you know of one that has an autosize property and hides the selection box and caret which pretty much will leave you with a (drumroll please) label with a lines property :)

unit MultilineLabel;

interface

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

type
  TMultilineLabel = class(TLabel)
  private
    FLines: TStrings;
    function GetLines: TStrings;
    procedure SetLines(Value: TStrings);
  protected
  public
    constructor Create(aOwner: TComponent); override;
    destructor Destroy; override;
  published
    property Lines: TStrings read GetLines write SetLines;
  end;

procedure Register;

implementation

procedure Register;
begin
  RegisterComponents('Tests', [TMultilineLabel]);
end;

constructor TMultilineLabel.Create(aOwner: TComponent);
begin
  inherited Create(aOwner);
  FLines := TStringList.Create;
end;

destructor TMultilineLabel.Destroy;
begin
  FLines.Free;
  inherited;
end;

function TMultilineLabel.GetLines: TStrings;
begin
  Result := FLines;
  Result.Text := Caption;
end;

procedure TMultilineLabel.SetLines(Value: TStrings);
var
  i                 : Integer;
begin
  FLines.Assign(Value);
  Caption := '';
  for i := 0 to FLines.Count - 1 do
  begin
    Caption := Caption + FLines[i];
    if (i < FLines.Count - 1) then
      Caption := Caption + #13#10;
  end;
end;

end.

tried

MultilineLabel1.Lines.LoadFromFile('readme.txt');

It's not difficult to read the file.

var
  f : file;
  s : string;
begin
AssignFile(f,'readme.txt');
FileMode := fmOpenRead;
Reset(f,1);
SetLength(s,filesize(f));
BlockRead(f,s[1],length(s));
CloseFile(f);
MultilineLabel1.Caption := s;

If only difference from standart TLabel is possibility to load text from file - there is no need to use another component. There also is no need to use TStrings, which has many needless functions in this case.
