I'm not saying it's the right or the best way, but in the interest of 
giving you something to work with I do this:


procedure TListForm.FormCreate(Sender: TObject);

CONST   startParam= 0;

begin
..
     Application.QueueAsyncCall(@OnAfterShow, startParam) (* Keep at end *)
end { TListForm.FormCreate } ;


PROCEDURE TListForm.OnAfterShow(afterShowParam: PtrInt);

(* guaranteed to be after all form creation etc. has completed.         *)

BEGIN
..
END { TListForm.OnAfterShow } ;


That can loop, but make sure you put Application.ProcessMessages in it.
