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

[detail level 12]

CABenchmark	Quick access to benchmarking two functions for the purpose of performance testing
CADataBaseSetup	Responsible for the inital setup of the database when the application is first launched. It creates the database in the specified default location and creates all required tables and views. It can also be used to reset the database currently used
▼Cexperimental::AEntry	The Entry class encapsulates table metadata(table name, row id) and data for new and existing entries in the database to operate on
Cexperimental::AAircraftEntry
Cexperimental::AFlightEntry
Cexperimental::APilotEntry
Cexperimental::ATailEntry
CARunGuard	The RunGuard class ensures only a single instance of the application is running simultaneously
CASettings	The Settings class is a thin wrapper for the QSettings class, simplifying reading and writing of settings
CDb	Basic API for accessing the database programatically. It is used to set up the initial connection and various basic queries can be executed using a set of static functions. When interfacing with the database for the purpose of adding, deleting or updating entries, the use of the entry class and its subclasses is recommended. This clas is not supposed to be instantiated, if you need a database object, use QSqlDatabase::database("qt_sql_default_connection");
CDbInfo
▼CEntry_deprecated	The Entry class is the base class for database entries. It can be seen as a row in a table within the database
CAircraft	The aircraft class
CFlight
CPilot
▼CQDialog
CFirstRunDialog
CNewFlightDialog
CNewPilotDialog
CNewTailDialog	The NewTail class is a dialog for adding a new tail to the database or editing an existing one
▼CQObject

Cexperimental::ADatabase	The DB class encapsulates the SQL database by providing fast access to hot database data
▼CQPair
Cexperimental::DataPosition
▼CQRegularExpressionValidator
CAStrictRxValidator	Only returns Invalid or Acceptable
▼CQSqlError
Cexperimental::ADatabaseError	Custom Database Error derived from QSqlError. Extends text() adding "Database Error: " before the text
▼CQWidget
CAircraftWidget
CDebugWidget
CHomeWidget
CLogbookWidget
CPilotsWidget
CSettingsWidget
CTotalsWidget
Cexperimental::UserInput	The EntryData struct. Contains ALL possible data. However depending on who is constructing it, different types are initialised. FUTURE: Would it be necessary to able to change data? George: I would say no because we dont want to fuck around with the entry. Collect data from user -> Pack it up in the entry -> Consume it
