VCL spinner

[Jud 1]

Is there a VCL component that does something like the Windows spinner?  I looked through the VCLs and didn't see one.  And which group is it under (System, additional, Win, etc)?

 

Added: Actually, I need something sort of like the ProgressGuage, where I update it periodically to show that a loop is still executing.  I need to update it every few seconds to show that it is still executing, rather than a percentage finished.

Have a look at TNumberBox.

TAdvCircularProgress does it . It turns until you stop it.

There are quite a few like it that work until you stop them.

AFAIK, a Windows Spinner control is an edit containing numbers with arrows to increase/decrease.

@Uwe Raabe the above is what he needs

no numbers. There are times when you do not know your process's time(size), so there are times like the above. it is active until you stop it.

This program of mine does exactly his needs. turn until you stop

Thanks, I'm going to look at those.  However, I don't need one that runs until I stop it.  I need one that verifies that the program is still running.  I need to update it periodically.  After I posted the message, I realized that a simple thing to do would be to have a label with just '*' and make it visible or not visible every X times through the outer loop.

 

I had a strange problem the other day.  I had an i7 running 14 threads of a big computation.  It was going to take 15-16 days.  It stopped running at 92% finished.  None of the CPUs were executing the calculations, but strangely, everything in the Windows user interface still worked.  It didn't bomb out or lock up. The calculation had been stopped for about 2 days when I realized it. I've never had that happen before.  And nine other i7s running the same program on different data haven't had the same problem.  This is to check to see if the program is still executing the calculations.

I do not know of a component to do that,

If a program is still running that means what?

showing? calculating? finished closed?

TProgressBar with Style=pbstMarquee. Update it by calling TProgressBar.StepIt.

@Anders Melander what he needs is not a progress

It's not a progress bar; It's a marquee.

Thanks but I think I'll take OP's words over your interpretation of "his needs".
