<h2>Detailed Description</h2>
<p>The QWSScreenSaver class implements a screensaver in Qtopia Core.</p>
<p>Derive from this class to define a custom screensaver, note that there exists no default implementation. Reimplement the <a href="qwsscreensaver.html#restore">restore</a>() and <a href="qwsscreensaver.html#save">save</a>() functions. These functions are called whenever the screensaver is activated or deactivated, respectively. Once the custom screensave is created, use the <a href="qwsserver.html#setScreenSaver">QWSServer::setScreenSaver</a>() function to install it.</p>
<p><a href="qwsserver.html">QWSServer</a> also provides means of controlling the screensaver, see the <a href="qwsserver.html#display-handling">QWSServer</a> class documentation for details.</p>
<p>See also <a href="qwsserver.html">QWSServer</a>, <a href="qscreen.html">QScreen</a>, and <a href="qtopiacore.html">Qtopia Core</a>.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="dtor.QWSScreenSaver"></a>QWSScreenSaver::~QWSScreenSaver () <tt> [virtual]</tt></h3>
<p>Reimplement this function to destroy the screensaver.</p>
<h3 class="fn"><a name="restore"></a>void QWSScreenSaver::restore () <tt> [pure virtual]</tt></h3>
<p>Reimplement this function to deactivate the screensaver.</p>
<p>See also <a href="qwsserver.html#screenSaverActivate">QWSServer::screenSaverActivate</a>() and <a href="qwsscreensaver.html#save">save</a>().</p>
<h3 class="fn"><a name="save"></a>bool QWSScreenSaver::save ( int <i>level</i> ) <tt> [pure virtual]</tt></h3>
<p>Reimplement this function to return true if the screensaver successfully enters the timeout interval specified by the <i>level</i> parameter; otherwise it should return false.</p>
<p>The timeout intervals are typically specified using the <a href="qwsserver.html#setScreenSaverIntervals">QWSServer::setScreenSaverIntervals</a>() function.</p>
