When I show the QDirModel by QTableView
There will be four columns — Name, Size, Type, Date Modified
I don’t want the user be able to select Size, Type, and Date Modified
How could I disable the selection on specific columns?

The most easiest solution I could think of is design a delegate to
repaint the columns I don’t want the user to select

class disableSelectionDelegate : public QStyledItemDelegate
{
public:
explicit disableSelectionDelegate(QObject *parent = 0)
: QStyledItemDelegate(parent)
{
}
void paint(QPainter *painter, const QStyleOptionViewItem &option,
const QModelIndex &index) const
{
painter->drawText(option.rect, Qt::AlignCenter, index.data().toString() );
}
};

Thank you very much

You need subclass QDirModel and reimplement flags() function.

Qt::ItemFlags DirModel::flags(const QModelIndex &index) const
{
if(index.column() == 2) return QDirModel::flags(index)&~Qt::ItemIsSelectable;
return QDirModel::flags(index);
}

Thanks, I didn’t discover I could override the flag
