It's no need to do it in delegate. The delegate will make your style sheet unavailable. You can paint the icon in the middle of a rectangle pixmap which is as same size as the cell, and return it in the QAbstractItemModel::data() function with Qt::DecorationRole. Like this:

Qt::DecoratoinRole:
    QPixmap pixmap(w, h);  //w=cell width, h=cell
    pixmap.fill(Qt::transparent); // draw a transparent rectangle
    QPixmap iconPixmap(":/xx.png");
    QPainter painter(&pixmap);
    //Calculate the center coordinate x,y for iconPixmap
    painter.draw(x, y, iconWidth, iconHeight, iconPixmap);
    return pixmap;
