Documentación de las funciones miembro

QSqlDatabase * QSqlDatabaseManager::addDatabase	(	QSqlDatabase *	db,
		const QString &	name
	)		[static]

Adds a database to the SQL connection manager. The database connection is referred to by name. The newly added database connection is returned. This function will only return 0 if it is called before a QApplication object has been instantiated. Use the output of drivers() to determine whether a particular driver is available or not.

The returned QSqlDatabase object is owned by the framework and must not be deleted. If you want to explicitly remove the connection, use removeDatabase().
