Detailed Description

The QWSScreenSaver class implements a screensaver in Qtopia Core.

Derive from this class to define a custom screensaver, note that there exists no default implementation. Reimplement the restore() and save() functions. These functions are called whenever the screensaver is activated or deactivated, respectively. Once the custom screensave is created, use the QWSServer::setScreenSaver() function to install it.

QWSServer also provides means of controlling the screensaver, see the QWSServer class documentation for details.

See also QWSServer, QScreen, and Qtopia Core.
