It is provided for compatibility with the private <a href="qglobalstatic.html#Q_GLOBAL_STATIC">Q_GLOBAL_STATIC</a> implementation that existed in Qt 4.x and 5.0. New code should avoid using it and should instead treat the object as a smart pointer.</p> <!-- @@@operator() --> </div> </div> </div> </div> </div> <div class="footer"> <p> <acronym title="Copyright">©</acronym> 2019 The Qt Company Ltd.
