    Question Only let one instance of the application run

    I need to figure out how to get just one instance of my application to run. Currently
    there can be more than one instance running on the same machine. Under the windows
    API I would just say if(!hPrevInstance) in WInMain. Does anyone know how its done in QT

    Thanks,
    chrisdsimpson
