Hum,...
Why not directly in ttimer.ontimer() ?
procedure ttimer.ontimer();
begin
if all_is_ok then dothis_and_continuetimer()
else ttimer.enabled := false;
end;
This question because of:

Hello Martin.
OK, capito the use of to_single. Thanks for the light.

OK.
But how do you do for something like this:
procedure ttimer.ontimer();
begin

If the time used in ontimer is bigger than the interval time there will be
100% CPU power used and the delayed ontimer events will be called when

With to_single the timer will be fired once after ttimer.enabled will be set

Hello Martin.
I did extensive test of a project on processors i386 (32 and 64 bit)

OK, on all OS, perfect.
But on arm rpi 32 bit, there was problems, for example zooming was not
working any more.
After hard investigations, I did find something that fixes all.
