Calling setPos() on custom QGraphicsPixmapItem doesn't update item in GraphicsScene

[jzacks524]

Hello, I'm working on a little poker game and I am having a graphical glitch I would like to understand better and fix. For my "Card" class I subclassed QGraphicsPixmap items and added a 52-card "deck" to my QGraphicsScene.

During runtime, I click on a button to deal the cards which then calls setPos() on the first three to simulate a flop.

The problem is, the cards don't appear to fully draw themselves right away (see photos). When I resize the window suddenly they pop into full view. The QGraphicsView is not being updated when a card position changes.

I tested calling setPos() on my background image which is a regular QGraphicsPixmap item and it moves properly and immediately updates the entire QGraphicsScene, so I'm thinking it has to be some error I've made while creating my "Card" class, but I'm not sure what I'm doing wrong.

pokerTable.cpp (relevant portion)

void PokerTable::dealFlop()
{
    m_deck->burnCard();
 
    m_flopCard1 = m_deck->dealCard(); // dealCard() returns a pointer to a Card, stored in these data members
    m_flopCard2 = m_deck->dealCard();
    m_flopCard3 = m_deck->dealCard();
 
    m_flopCard1->setPos(m_flopCard1Position); //QPointF positions
    m_flopCard2->setPos(m_flopCard2Position);
    m_flopCard3->setPos(m_flopCard3Position);
}

void PokerTable::dealFlop()
{
    m_deck->burnCard();

    m_flopCard1 = m_deck->dealCard(); // dealCard() returns a pointer to a Card, stored in these data members
    m_flopCard2 = m_deck->dealCard();
    m_flopCard3 = m_deck->dealCard();

    m_flopCard1->setPos(m_flopCard1Position); //QPointF positions
    m_flopCard2->setPos(m_flopCard2Position);
    m_flopCard3->setPos(m_flopCard3Position);
}
