Does QEvent::TouchUpdate get triggered when you stop one of multiple touches Qt

I am writing a program in Qt where I need to detect when one finger is lifted from the screen while others are still down. I tried to use QEvent::TouchUpdate as such

bool MyClass::event(QEvent *event)
{
     switch(event->type())
     {
     case QEvent::TouchUpdate:
     {
          if(//some logic to detect if one finger has been lifted)
          {
               //Change some variables
               update();
          }
          else if(//some logic to detect if finger is being dragged)
          {
               //Change some variables
               update();
          }
     }
     }
     return QWidget::event(event);
}

After testing this I found that the everything updates fine, but only once I drag the second finger. I assume this means that removing my finger from the screen while others are down isn't considered an "event" or that it isn't part of TouchUpdate. Am I doing something wrong? Or is there a another way for me to detect this?
