    Hi I got an application running in fullscreen with QGraphicsView on my N900, but after a few seconds the screen turns black..
    I guess this is normal, but I want it to stay on.

    Any help please ? :) Cannot find any info on this..

        Aha! Thank you, I think I need to use QSystemScreenSaver :)

        Edit: Qt is the best!

          Did it work? I don't see any methods on the "QSystemScreenSaver":http://doc.qt.nokia.com/qtmobility-1.1/qsystemscreensaver.html class.

          I haven't implemented myself but remember reading somewhere that the only way to prevent the screen from dimming is to send (I think) a dbus signal every so often. I am sure you can find the details on the maemo.org web site.
