qt - How to center QPixmap while Painting it inside QItemDelegate of QListWidget

Question

I'm painting a QPixmap inside the QItemDelegate of QListWidget. Each QListWidgetItem is of different dimensions. Inside the

void paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) 

function of QItemDelegate, I want to paint QPixmap with center Alignment inside the QListWidgetItem. option.rect() gives the geometry of the item with which I can calculate the center position and paint accordingly, but I want to know the better approach for this alignment.Can some one let me know the answer?

Answer 1

Do you know the dimensions of your QListWidgetItem? If so, just paint the QPixmap yourself with something like:

painter->drawPixmap(
    (item->width() - pixmap->width()) / 2,
    (item->heigt() - pixmap->height()),
    pixmap
);
