Rotate QGraphicsPixmapItem

Okay, I've been sitting on this issue for at least 4 hours now and just am exhausted.
I'm trying to simply rotate a QGraphicsPixmapItem by 45Â° around its own axis.

Qt Code:

Switch view

MyPixmap::MyPixmap() : QGraphicsPixmapItem()
{
    this->setPixmap(QPixmap("wallpaper.jpg"));
 
    QTransform t = this->transform();
 
    t.translate(this->pixmap().width()/2, this->pixmap().height()/2);
    t.rotate(45, Qt::XAxis);
    t.translate(-this->pixmap().width()/2, -this->pixmap().height()/2);
 
    this->setTransform(t);
}

MyPixmap::MyPixmap() : QGraphicsPixmapItem()
{
    this->setPixmap(QPixmap("wallpaper.jpg"));
    
    QTransform t = this->transform();

    t.translate(this->pixmap().width()/2, this->pixmap().height()/2);
    t.rotate(45, Qt::XAxis);
    t.translate(-this->pixmap().width()/2, -this->pixmap().height()/2);

    this->setTransform(t);
}

To copy to clipboard, switch view to plain text mode

I tried alot of other options but the image is always moving around the whole screen and this is what comes out:

Shouldn't the lower edge be large and the upper edge small, like a trapezoid? Anyway, that's what I want it to be but it seems like I'm missing something here
