change LayoutDirection of some columns

[rosenth]

In a QTableWidget, i need some columns to be in layoutDirections other than tables default direction.
is it possible?

Sounds like a job for a custom item delegate.

[rosenth]

i know how to reimplement, but in which function and what object i should apply direction?

[ChrisW67]

I don't have any RTL text experience but it seems that QStyledItemDelegate::paint() of your custom delegate class could switch the painter layout direction before formatting/rendering the text.

thanx.

void QCustomStyledItemDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
QStyleOptionViewItem styleOption(option);
styleOption.direction=Qt::LeftToRight;
styleOption.displayAlignment=Qt::AlignRight;

QStyledItemDelegate::paint(painter,styleOption,ind ex);
}
