1st
There are some things that I don't understand for the QTimer class for QT. What the method timerId() is used for? It returnes the Id of the timer, but what is that ID.

2nd
And can somebody explain to me how the algorythm goes for the following program: as the timer goes by, in the widget "lineEdit1" to be written the countdown of the timer..example: The timer to be set to go from 1000-10000, and after activating with a pushButton, in the lineEdit1 to write the seconds from 1-10, as the timer goes to the timeout.

I just can't find the code...

Please help me
