TThread Execute Methode dauerhaft laufen lassen

[sk0r]

Naja, das Problem ist, wenn ich

Delphi-Quellcode:

procedure Thread.Execute;
begin
  while true do
  begin  
    //Irgendwas machen
    Sleep(10);
  end;
end;

benutze, dann wird meine Hauptanwendung blockiert. :/

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

  thread = class(TThread)
    procedure Execute;
  end;

var
  Form1: TForm1;
  gthread: thread;

implementation

{$R *.dfm}

procedure thread.Execute;
begin
  while true do
  begin
    ShowMEssage('TEST');
    Sleep(10);
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  gthread := thread.Create(true); 
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  gthread.Execute;
end;

end.
