<h2 id="details">Detailed Description</h2>
<p>Convenience class for custom <a href="qdebug.html">QDebug</a> operators.</p>
<p>Saves the settings used by <a href="qdebug.html">QDebug</a>, and restores them upon destruction, then calls <a href="qdebug.html#maybeSpace">maybeSpace()</a>, to separate arguments with a space if <a href="qdebug.html#autoInsertSpaces">autoInsertSpaces()</a> was true at the time of constructing the <a href="qdebugstatesaver.html">QDebugStateSaver</a>.</p>
<p>The automatic insertion of spaces between writes is one of the settings that <a href="qdebugstatesaver.html">QDebugStateSaver</a> stores for the duration of the current block.</p>
<p>The settings of the internal <a href="qtextstream.html">QTextStream</a> are also saved and restored, so that using << hex in a <a href="qdebug.html">QDebug</a> operator doesn't affect other <a href="qdebug.html">QDebug</a> operators.</p>
