    Given a QSqlQueryModel and a QTableView.

    How exactly are items displayed, wrt QStyledItemDelegate vs QSqlQueryModel::data()?

    Specifically: when an item is just being displayed, i.e. Qt::DisplayRole, does the (default?) QStyledItemDelegate call QSqlQueryModel::data(index, Qt::DisplayRole) to get the string representation of the data and display that, or does the (default?) QStyledItemDelegate have its own code to do the display role/string work?

      Hi,

      It will call QModelIndex::data that it will then feed to displayText in order to have the text to draw in the cell.
