I have a listview component on a form and would like one of the columns to be a clock counting down to zero.

Does anyone know how I can do this?

Would this be a different clock for every item in the listview?

put a timer on your form which has the ListView

in the OnTimer event change the value of the CountDown
and update the ListView

type
  TForm1 = class(TForm)
  private
    fCountDown: integer;
  end;
 
procedure TForm1.Timer1OnTimer(Sender: TObject);
begin
  if CountDown > -1 then
  begin
    CountDown := CountDown - 1;
    ListView1.Items.Item[0].SubItems[1] := IntToStr(CountDown);
  end else Timer1.Enabled := False;
end;
