Put the progressbar anywhere on the form and hide it. When you start the process, set the Progressbar.Parent to the statusbar and adjust its location (this is a bit tricky, IIRC). Finally show the progressbar. At the end of the process, hide it again.

This works perfectly for Windows but I think it fails for Linux GTK2. I seem to remember stumbling on this on another program.
But I have to tell you to take this with a grain of salt cuz my memory is crap and I could be remembering it wrong :(

Cheers,
Gus

I remember finding a snippet you could "simulate" a Progressbar anywhere that offers a canvas without using the ProgressBar-Control.
But i would have to dig up my Fedora-Hat an Bullwhip and go on a jungle-hunt to find that snippet again....

Works on windows, linux and osx(Lazarus 2.0.12/FPC 3.2.0). You can customize the appearance.

I now stand corrected and have only one thing to say: AWESOME SAUCE!!!

You da man GetMem, thank you so much for this!!!
This cures my fear of doing it due to past bad experiences and I'll use it extensively :P

Cheers,
Gus

I create the progressbar at fly in this way

TForm1...
...
    StBar: TStatusBar;
    PrBar : TProgressBar;
...
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  ....
  PrBar:=TProgressBar.Create(StBar);
  PrBar.Parent:=StBar;
  ...
end;

and also (I have the progressbar in a panel with index = cPnlPrBar)

procedure TForm1.StBarDrawPanel(StatusBar: TStatusBar; Panel: TStatusPanel; const Rect: TRect);
begin
  if (Panel = StatusBar.Panels[cPnlPrBar]) then
    PrBar.BoundsRect:=Rect
end;
