TableModel question about Qt::CheckStateRole

[Perdrix]

The data for my table is held in a vector of class instances.

If the data in a class instance that represents a row/column intersection is changed, I know I need to tell the TableModel that it has been changed.

My data mf() for the model has:

if (role == Qt::CheckStateRole)
{
      if (0 == index.column())
          return file.m_bChecked;   // can be QT::Checked or Qt::Unchecked
      else return QVariant();
}

What should I do if I modify the m_bChecked variable for a row - do I tell the model that column 0 of the row has changed or ???

@Perdrix
In your code you only use m_bChecked for column #0, so if you alter that you need to emit dataChanged() for column #0 with role Qt::CheckStateRole. Is that what you were asking?

Yes I think it was
