This inheritance list is sorted roughly, but not completely, alphabetically:

▼CAEntry	The Entry class encapsulates table metadata(table name, row id) and data for new and existing entries in the database to operate on
CAAircraftEntry
CACurrencyEntry
CAFlightEntry
CAPilotEntry
CATailEntry
COpl::ANotificationHandler	Handles displaying of user-directed messages. It displays information to the user and forwards the displayed message to ALog so it is written to the console and log files. The INFO, WARN and CRIT makros provide convenient access
CARunGuard	The RunGuard class ensures only a single instance of the application is running simultaneously
CASettings	Thin wrapper for the QSettings class, simplifying reading and writing of settings

CADatabaseError	Custom Database Error derived from QSqlError. Extends text() adding "Database Error: " before the text
▼CQStandardItem
CAFileStandardItem	Simple QStandardItem subclass to encapsulate necessary file info.

CAircraftWidget	The AircraftWidget is used to view, edit, delete or add new tails
CBackupWidget
