Помещение VCL компонентов в область заголовка

Code:

unit Unit1;

interface

uses

Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms,

Dialogs, StdCtrls;

type

TForm1 = class(TForm)

   procedure FormResize(Sender: TObject);

   procedure FormShow(Sender: TObject);

   procedure FormHide(Sender: TObject);

private

   { Private declarations }

public

   { Public declarations }

   procedure WMMove(var Msg: TWMMove); message WM_MOVE;

end;

var

Form1: TForm1;

implementation

uses Unit2;

{$R *.DFM}

procedure TForm1.FormResize(Sender: TObject);

begin

with Form2 do

begin

   {Заменим мои магические числа реальной информацией SystemMetrics}

   Width := Form1.Width - 120;

   Top := Form1.Top + GetSystemMetrics(SM_CYFRAME);

   Left := ((Form1.Left + Form1.Width) - Width) - 60;

end;

end;

procedure TForm1.FormShow(Sender: TObject);

begin

Form2.Show;

end;

procedure TForm1.FormHide(Sender: TObject);

begin

Form2.Hide;

end;

procedure TForm1.WMMove(var Msg: TWMMove);

begin

inherited;

if (Visible) then

   FormResize(Self);

end;

end.

Code:

Caption='' {NULL строка}

Height={высота области заголовка}

Width={высота всех компонентов на форме}

BorderIcons=[] {пусто}

BorderStyle=bsNone

FormStyle=fsStayOnTop

Code:

unit Unit2;

begin

Form1.SetFocus;

end;

procedure TForm2.FormResize(Sender: TObject);

begin
