Hello Peter,

you are rebinding the variable indicator. This destroys the reference which you
get from Qt. In C++, operator= of QString is overloaded and the instance is not
destroyed. Just modify the instance, exchange

indicator = "Measuring..."

with

indicator.truncate(0)
indicator +=  "Measuring..."

Then it works for me. Although I wonder why
indicator = time.toString()
does not destroy the reference, too.


greetings

Torsten
