Question

How could one reset the TTimer1 so even ontimer triggers, and the count restarted?

The Question is for Design Time command to act on Run-time.

Answer 1

I suppose you actually mean that

var
  Timer1: TTimer;

Then, to reset the timer, do

Timer1.Enabled := false;
Timer1.Enabled := true;

In my “RejbrandCommon.pas” standard library, I have actually defined

procedure RestartTimer(Timer: TTimer);
begin
  Timer.Enabled := false;
  Timer.Enabled := true;
end;

Then, every time I need to restart I timer, I just do

RestartTimer(Timer1);

Of course, if you want the OnTimer procedure (e.g. Timer1Timer) to trigger prior to restart, you have to do

Timer1.OnTimer(Self);
Timer1.Enabled := false;
Timer1.Enabled := true;

or define

procedure TriggerAndRestartTimer(Timer: TTimer);
begin
  Timer.OnTimer(nil);    
  Timer.Enabled := false;
  Timer.Enabled := true;
end;

(Of course, the last procedure, TriggerAndRestartTimer, is not a method, and hence there is no Self. However, most likely the Timer1Timer procedure doesn’t care about the Sender property, so you can send just anything, such as nil instead of Self.)
