Used to supply item data to views and delegates.
Generally, models only need to supply data for Qt::DisplayRole and any application-specific user roles, but it is also good practice to provide data for Qt::ToolTipRole, Qt::AccessibleTextRole, and Qt::AccessibleDescriptionRole. See the Qt::ItemDataRole enum documentation for information about the types associated with each role.
