title: QT: Event for 'Up' and 'Down' arrows in QTimeEdit widget
body: <p>I am using Qt Creator 4.5.2 (Qt 5.9.5, GCC 7.3.0 64-bit) and running on Ubuntu 18.04. </p>
  
  <p>I just customized the 'QTimeEdit' widget and it worked. Now, I need to intercept the event(s) for the 'Up' and 'Down' arrow (the arrow to change the current time). But, I don't know which event it is.
  I already installed the 'evenFilter' and could catch all the events. I printed out all of them. But, I did not see an event trigger when I clicked the 'Up' or 'Down' arrow (The time did get changed). I assumed it was 'keyPressEvent' but apparently it was not since it did not trigger this method when I clicked the 'Up' or 'Down' arrow.</p>
  
  <p>Any idea what events for the 'Up' or 'Down' arrow in the 'QTimeEdit' widget?</p>
  
  <pre><code>void MyTimeEdit::keyPressEvent(QKeyEvent *e)
  {
     qInfo() &lt;&lt; "Key Press";
     QTimeEdit::keyPressEvent(e);
  }
  
  bool MyTimeEdit::eventFilter(QObject *watched, QEvent *event)
  {
     if(watched == lineEdit())
        qInfo() &lt;&lt; "Event Type: " &lt;&lt; event-&gt;type();
     return QTimeEdit::eventFilter(watched, event);
  }
  </code></pre>
