To restore the values to previous state I am using QSettings to store the values in a file in *.ini format.
This is happening when closeEvent() function is called.
But I am trying to restore the values of GUI to previous state when application exits on system signal like SIGTERM or KILL.
Able to catch Unix signal like SIGTERM in Qtopia 4.2 using signal handler, but could not able to update the values of GUI using QSettings, when SIGTERM is signalled to application.

Thanks & Regards,
Arun
