Programatically add USerRole data to specific cell of QAbstractTableMode

[franco.amato]

QAbstractTableModel does not re-implement setData(), so it is using the implementation from its base class, QAbstractItemModel. The documentation for QAbstractItemModel::setData() says:



So if you have not implemented setData() in your own model (derived from QAbstractTableModel), then using the default setData() method is doing nothing to store your string.

This tutorial would be a good place to start. There is a section on creating an editable model.

Sorry I had misunderstood your previous message.
Yes I implemented a setData from my model.

I write it below:

bool SelectedListModel::setData(const QModelIndex &index, const QVariant &value, int role)
{
    if (!index.isValid())
    {
        return false;
    }
    if (role == Qt::EditRole)
    {
        m_reports[index.row()].replace("actionName", value.toString());
 
        emit dataChanged(index, index);
        return true;
    }
}

bool SelectedListModel::setData(const QModelIndex &index, const QVariant &value, int role)
{
    if (!index.isValid())
    {
        return false;
    }
    if (role == Qt::EditRole)
    {
        m_reports[index.row()].replace("actionName", value.toString());

        emit dataChanged(index, index);
        return true;
    }
}

It is not clear to me how to add data with a custom role.
Can you help me with a small example?
