Machine Idle time.

How to find out machine idle time using qt c++ ?
i want to store machine idle duration in database..

I do not think Qt will have anything for this. A call to determine "machine idle time" (whatever your definition) is going to be highly OS-specific and require non-generic calls. You also don't say whether you are interested in one OS or need to be cross-platform?

I suggest you start by Googling for c++ machine idle time and see what you think of the hits. You can incorporate non-Qt C++ code into a Qt application if you find the OS call you wish to use.

private:
QPoint mouseLastPos;
QTimer *mouseTimer;
quint32 mouseIdleSeconds;

mainwindow.cpp - Constructor method
//Init
mouseTimer = new QTimer();
mouseLastPos = QCursor::pos();
mouseIdleSeconds = 0;

//Connect and Start
connect(mouseTimer, SIGNAL(timeout()), this, SLOT(mouseTimerTick()));
mouseTimer->start(1000);

mainwindow.cpp - Class body
void MainWindow::mouseTimerTick()
{
QPoint point = QCursor::pos();
if(point != mouseLastPos)
mouseIdleSeconds = 0;
else
mouseIdleSeconds++;

mouseLastPos = point;

//Here you could determine whatever to do
//with the total number of idle seconds.

}

this works for me as per my requirement.
Thank you all..!

I do not see how this has anything to do with "Machine Idle time", but up to you.... (In that light, I wouldn't mind reading whatever you mean by "Reference taken from stackoverflow." ?)
