QProgressBar inside QTableView column (Size problem)

Proton Phoenix

Hi `~ I Have A Size problem on progressbar inside QTableView (Table is from Right To left)
the progressbar takes the size of it's column 1 and other column 0 which is not a linked with it

it contains headers TEXT.. i just clean it with paint
when i click to column 0 (from the right to left) it remove the progressbar and when i click something else it comes back as the picture
here's my code

expiredatesDelegate::expiredatesDelegate(QObject *parent)
    : QStyledItemDelegate{parent}
{

}
void expiredatesDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option,
                           const QModelIndex &index) const
{
    if (index.column() == 1) {
        int progress = index.data().toInt();
        QStyleOptionProgressBar progressBarOption;
        progressBarOption.rect = option.rect;
        progressBarOption.state = QStyle::StateFlag::State_Horizontal;
        progressBarOption.minimum = 0;
        progressBarOption.maximum = 100;
        progressBarOption.progress = progress;
        progressBarOption.text = QString::number(progress) + "%";
        progressBarOption.textVisible = true;
        progressBarOption.textAlignment =Qt::AlignCenter;
        painter->setFont(QFont("Arial",10));
        QApplication::style()->drawControl(QStyle::CE_ProgressBar,
                                           &progressBarOption, painter);
    } else
        QStyledItemDelegate::paint(painter, option, index);
        
}

ui->tableView->setModel(expiredatesmodel);
    ui->tableView->setColumnWidth(0,260);
    ui->tableView->setColumnWidth(1,260);
    ui->tableView->setColumnWidth(2,170);
    ui->tableView->setColumnWidth(3,170);
/****/*
   ui->tableView->model()->setData(index,productname[i],1);
    ui->tableView->setItemDelegate(new expiredatesDelegate());

Try this:

instead of ui->tableView->setItemDelegate(new expiredatesDelegate()); call ui->tableView->setItemDelegateForColumn(1,new expiredatesDelegate());
change paint to:

void expiredatesDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option,
                           const QModelIndex &index) const
{
QStyleOptionViewItem opt = option;
    initStyleOption(&opt, index);
        const int progress = index.data().toInt();
        QStyleOptionProgressBar progressBarOption;
        progressBarOption.rect = opt.rect;
        progressBarOption.direction = opt.direction;
        progressBarOption.fontMetrics= opt.fontMetrics;
        progressBarOption.palette= opt.palette;
        progressBarOption.state = opt.state | QStyle::State_Horizontal;
        progressBarOption.styleObject = opt.styleObject;
        progressBarOption.minimum = 0;
        progressBarOption.maximum = 100;
        progressBarOption.progress = progress;
        progressBarOption.text = tr("%1%").arg(progress);
        progressBarOption.textVisible = true;
        progressBarOption.textAlignment =Qt::AlignCenter;
painter->save();
        painter->setFont(QFont("Arial",10));
        (opt.widget ?  opt.widget.style : QApplication::style())->drawControl(QStyle::CE_ProgressBar,
                                           &progressBarOption, painter);
painter->restore();
}

Hi Thank you so much bro
i tried it but almost the same
only it changes it's direction

using ui->tableView->setItemDelegateForColumn(1,new expiredatesDelegate());

it looks like this

using

ui->tableView->setItemDelegate(new expiredatesDelegate());

but it got it's right size but i lost other columns ^^ i am sure there's a very close solution now ~~ Where it is ^^?

@VRonin
you knew what bro :D ^^ when the model gets data there's a values higher than the max of the progressbar that's why it takes the size of other columns ... when i set higher progressBarOption.maximum = 100;
problem solved
Thank you so much
without you i coudn't find it even if it was that easy
