Stoping the Screensaver.

Hi I'm writing a simple slideshow widget for my application, I'm trying to stop the screensaver from poping up. I tried changing the cursors pos by 1 (I know it was a dirty idea :o) but had no succes. Does anyone know of a way how to stop that damnd thing from showing up.
Thanks.

If you are using windows, you can use QSettings to edit the ScreenSaveActive value to 1 to disable the screen saver in "HKEY_CURRENT_USER\Control Panel\Desktop."

On Linux I'm not sure, as there are multiple environments, Google is your best friend. :)
