library.</p>
<p>Many pieces of information are established when Qt is
configured. Installation paths, license information, and even a
unique build key. This class provides an abstraction for accessing
this information.</p>

<tr class="qt-style">
<th>Function</th>
<th>Return value</th>
</tr>

<tr class="odd" valign="top">
<td><a href="qlibraryinfo.html#buildKey">buildKey</a>()</td>
<td>A string that identifies the Qt version and the configuration.
This key is used to ensure that <a href="plugins.html">plugins</a>
link against the same version of Qt as the application.</td>
</tr>
<tr class="even" valign="top">
<td><a href="qlibraryinfo.html#location">location</a>()</td>

<p>You can also use a <tt>qt.conf</tt> file to override the
hard-coded paths that are compiled into the Qt library. For more
information, see the <a href="qt-conf.html">Using qt.conf</a>
documentation.</p>
