Synchronize sorting between tables

[Kouillo]

Hello.

I'm currently working on a Qt Project with QTableViews and QAbstractTableModel subclasses.

There are 2 synchronized tables (same number of row, synchronized scrollbar, etc.) and we are working on adding sorting on tables.

I use a customer QSortFilterProxyModel implementation to filter rows and sort model elements.

Here is an example/demo:

I wish to automatically arrange rows position in the right table when the left table is sorted by column (and vice-versa).

Is there any signal/slot mechanism to modify mapping tables of QSortFilterModel?

We try to implement something like :

bool SortFilterModel::lessThan(const QModelIndex &left, const QModelIndex &right) const
{
   if(m_b_isSortedFromOtherModel)
    {
        return otherInstance->lessThanFromOther(left, right);
    }
    else
    {
        return QSortFilterProxyModel::lessThan(left, right);
    }
}

bool SortFilterModel::lessThan(const QModelIndex &left, const QModelIndex &right) const
{
   if(m_b_isSortedFromOtherModel)
    {
        return otherInstance->lessThanFromOther(left, right);
    }
    else
    {
        return QSortFilterProxyModel::lessThan(left, right);
    }
}

But the result is not really conclusive, I think we could find something more simple...


Thanks for the help.
Bye.
