configuration.</p>
<p>The class provides two APIs: a set of non-static functions that
provide information about a specific widget or pixmap, and a set of
static functions that provide the default information for the
application.</p>
<p><b>Warning:</b> This class is only available on X11. For
querying per-screen information in a portable way, use <a href="qdesktopwidget.html">QDesktopWidget</a>.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QX11Info" />QX11Info.__init__ (<i>self</i>)</h3><p>Constructs an empty <a href="qx11info.html">QX11Info</a>
