Как поместить Progress Bar на Status Bar.

Компилятор: C++ Builder 3.x

Для формы:

object Form1: TForm1
  Left = 191
  Top = 108
  Width = 226
  Height = 140
  Caption = 'Form1'
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -11
  Font.Name = 'MS Sans Serif'
  Font.Style = []
  OnCreate = FormCreate
  PixelsPerInch = 96
  TextHeight = 13
  object StatusBar1: TStatusBar
    Left = 0
    Top = 94
    Width = 218
    Height = 19
    Panels = <
      item
        Width = 50
      end>
    SimplePanel = False
    OnResize = StatusBar1Resize
  end
  object Button1: TButton
    Left = 18
    Top = 30
    Width = 75
    Height = 25
    Caption = 'Button1'
    TabOrder = 1
    OnClick = Button1Click
  end
end
