<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qeventlooplocker.html">QEventLoopLocker</a> class provides a means to quit an event loop when it is no longer needed.</p>
<p>The <a href="qeventlooplocker.html">QEventLoopLocker</a> operates on particular objects - either a <a href="qcoreapplication.html">QCoreApplication</a> instance, a <a href="qeventloop.html">QEventLoop</a> instance or a <a href="qthread.html">QThread</a> instance.</p>
<p>This makes it possible to, for example, run a batch of jobs with an event loop and exit that event loop after the last job is finished. That is accomplished by keeping a <a href="qeventlooplocker.html">QEventLoopLocker</a> with each job instance.</p>
<p>The variant which operates on <a href="qcoreapplication.html">QCoreApplication</a> makes it possible to finish asynchronously running jobs after the last gui window has been closed. This can be useful for example for running a job which uploads data to a network.</p>
