Introduction
This assignment explores fundamental concepts of object-oriented
programming, reflection, model-view architecture, and input validation in the
context of software development using Qt. The practical tasks include designing
and implementing a vehicle management system, extending it with a FileWriter
class using meta-object reflection, developing a journal article database using
a QStandardItemModel and view, and ensuring robust validation of user
input.
The purpose of the assignment is to demonstrate the ability to apply Object-
Oriented Programming (OOP) principles, utilize Qt’s meta-object system,
implement dynamic sorting, filtering, and row highlighting in a model-view
setup, and enforce data integrity through input validation. Through these tasks,
learners gain practical experience in designing maintainable, extensible, and user-
friendly applications, while reinforcing the theoretical knowledge from the course
material.
QUESTION 1
Design and Implementation of a Vehicle Management System Using OOP
Principles in Qt
Solution: Vehicle Console Application (Qt C++)
1. Class Design
We have:
Vehicle (base class) – stores model and year
PassengerVehicle (derived class) – adds numPassengers
TransportVehicle (derived class) – adds carryingCapacityKg
