ScreenSaver function

Hi,

I am currently doing customization work for moto Z8(UIQ3.1).I would like to know if there is any function which able to change the screensaver?

For example, there is function like:

_LIT(KElementId, "StandbyScreen");
_LIT(KImageFile, "c:\\media files\\image\\pic");
QThemes::SetWallpaperL(KElementId, KImageFile());
 

I would like to know are there any similar function for screensaver? If no, then how our mobile devices able to change the screensaver respectively?

Thanks

Regards,

Adrian
