[Qt-interest] Sorting QTableWidget's column with checked items

[Malyushytsky, Alex]

For QTableWidget you probably can subclass
virtual bool operator< ( const QTableWidgetItem & other ) const
to take into account the values in the other columns ( in case *this == other )

Normally for QTableView you either would use

a) QSortFilterProxyModel overriding
bool QSortFilterProxyModel::lessThan ( const QModelIndex & left, const QModelIndex & right ) const   [virtual protected]
or would override


b) or directly overriding virtual void sort ( int column, Qt::SortOrder order = Qt::AscendingOrder ) in QAbstractTableModel or other QAbstractItemModel derived class


Regards,
            Alex

I found operator< for QTableWidgetItem - no question about this...
But how can I sort more that one columns?

Hi How can I sort column with checked items (these items haso no text at all)? I attach example with simple QTableWidget - it's first column has only checked items and I can't understand why item is moved to top after check-uncheck it... How can I reimplement QTableWidget's sorting behavior (I want implement own sort-order - I need sort QTableWidget by several columns)? Qt-4.5.0 Thanks
