Creating a QVector of QLabels in qt

I am trying to create a QVector of QLabels.

I am not sure how to go about this. I have declared my QVector like this: QVector<QLabel> labels

inside my .cpp file I want to set each label to a pixmap. Should I initialize all the instances through a for loop first?

Inside my constructor:

 for(int i = 0; i < usrinput; i++)
  {
     labels.append(new QLabel);
     setplayerpiece(i);
  }

I have a function outside of the constructor that sets each QLabel to an image:

   void CentralWidget::setplayerpiece(int tk)
{
  if (p[tk]->setpiece() == 0)
  {
    labels[tk]->setPixmap(QPixmap(":/images/hat.png"));
  }
  else if (p[tk]->setpiece() == 1)
  {
    labels[tk]->setPixmap(QPixmap(":/images/car.png"));
  }
  else if (p[tk]->setpiece() == 2)
  {
    labels[tk]->setPixmap(QPixmap(":/images/shoe.png"));
  }
  else if (p[tk]->setpiece() == 3)
  {
    labels[tk]->setPixmap(QPixmap(":/images/spaceship.png"));
  }
  else if (p[tk]->setpiece() == 4)
  {
    labels[tk]->setPixmap(QPixmap(":/images/basketball.png"));
  }
  else if (p[tk]->setpiece() == 5)
  {
    labels[tk]->setPixmap(QPixmap(":/images/ring.png"));
  }
}

Should i run another for loop in the constructor after I initialize labels that calls the function setplayerpiece for each instance? Essentially what I want to do is assign each player an image. If I was vague or you need more information please let me know. Thank you for any help.

How about this approach:

QVector<QString> playerIconPath;


playerIconPath.append(":/images/hat.png");
playerIconPath.append(":/images/car.png");
playerIconPath.append(":/images/shoe.png");
playerIconPath.append(":/images/spaceship.png");
playerIconPath.append(":/images/basketball.png");
playerIconPath.append(":/images/ring.png");

QVector<QLabel*> labels

for(int i = 0; i < playerIconPath.size(); i++)
{
    labels.append(new QLabel);
    labels[i]->setPixmap(QPixMap(playerIconPath[i]));
}

All this can be done inside the constructor if that's what you would like in your design.
