QTime

[wysota]

A bit more precise solution is to substract the elapsed time from 5 hours every time. It may happen that a timer event gets stalled, so substracting a second every time it is triggered might get your timer out of sync. But if you don't expect a heavy load, it should work fine too.

I have a question i only see the hours, minutes, seconds in the lcdNumber.
I.don't see the milliseconds.
Is this depending on the system where the program is running on.
How can i change the code to see the milliseconds and counting down in lcdNumber.

thanks in advance.

instead of time.toString() you can build your own representation by using QTime::hour(), minute(), second() and msec().
Just convert them to QString and concatenate them.

That, or:

time.toString("hh:mm:ss.zzz");

time.toString("hh:mm:ss.zzz");

To copy to clipboard, switch view to plain text mode 

There are other formatters from which you can choose.

I see in my lcdNumber the milliseconds but is not counting down only the seconds is counting down.
Must i time.addMSecs to the code?

[wysota]

You are only reducing the number of seconds so how do you expect anything else to change?

[marcel]

Yes, addMsecs(-x), where x is smaller than 1000, in order to see a difference.
