[Qt-interest] how do use the timer to calculate the time duration

[Yuvaraj R]

As per my requirement..

When i am clicking the accept call button that time timer will be starting..

When i am clicking the end call  button that time time will be stoping.

if i use the timer->elapsed( method.. it gives the one call duration time
only..

if i calculate duration for next call , it keep on running ,,, it is not
resetting ...

How do stop the timer,if once i click the end call button
