How to edit data in a TableModel/TableView?

[Overflow012]

Hello all,

I have the following code:

@
class CustomerTableModel < Qt::AbstractTableModel
...

def flag index
   return Qt::ItemIsEditable;
end

def setData index, value, role = Qt::EditRole
    if (index.isValid() && role == Qt::EditRole)
        update_value(index.row(), value.toString())
        emit dataChanged(index, index)
        return true
    end
    return false
 end

end

class GUICustomerWidget < Qt::Widget
def initialize
@tableView.set_model(CustomerTableModel.new())
@tableView.setEditTriggers( Qt::AbstractItemView::DoubleClicked )
end
end
@

TableView show all data but I can't edit. I'm reading "this page":http://www.qtforum.org/index.php?page=ExternalLink&url=http://qt-project.org/doc/qt-4.8/model-view-programming.html#making-the-model-editable but doesn't work. Should I add something to the tableView?
Can please anyone tell me what I do wrong?

You should override flags() method from QAbstractItemModel.
@
Qt::ItemFlags Model::flags(const QModelIndex &index) const
{
Qt::ItemFlags defaultFlags = QAbstractItemModel::flags(index);

if (index.isValid())
    return Qt::ItemIsEditable | defaultFlags;
else
    return defaultFlags;

}@

Sorry for c++ code))
