<div style="margin: 8px 0; padding: 0 12px; color: #74777D;"><p style="padding: 0; margin: 8px;">Reading the documentation <a href="http://doc.qt.io/qt-5/qelapsedtimer.html" class="remarkup-link" target="_blank" rel="noreferrer">http://doc.qt.io/qt-5/qelapsedtimer.html</a><br />
I'm not able to say if start() will restart a timer or continue. My guess is that it also restarts.<br />
And also because calling restart() on a QElapsedTimer that is invalid results in undefined behavior.</p></div></div>
<div style="margin: 8px 0; padding: 0 12px;"><p style="padding: 0; margin: 8px;">This does not matter - previously this line guaranteed that this does not fire again until <tt style="background: #ebebeb; font-size: 13px;">nextTimeout</tt> is set again. Now it will fire on the next <tt style="background: #ebebeb; font-size: 13px;">dispatchLoop()</tt> call.</p>
<p style="padding: 0; margin: 8px;">You probably want to call <tt style="background: #ebebeb; font-size: 13px;">d->nextTimeout.invalidate()</tt> here.</p></div></div><br /><div style="border: 1px solid #C7CCD9; border-radius: 3px;"><div style="padding: 0; background: #F7F7F7; border-color: #e3e4e8; border-style: solid; border-width: 0 0 1px 0; margin: 0;"><div style="color: #74777d; background: #eff2f4; padding: 6px 8px; overflow: hidden;"><a style="float: right; text-decoration: none;" href="https://phabricator.kde.org/D9983#inline-46019" rel="noreferrer">View Inline</a><span style="color: #4b4d51; font-weight: bold;">jtamate</span> wrote in <span style="color: #4b4d51; font-weight: bold;">slavebase.cpp:1052</span></div>
