Storekeeping Application (Qt/C++)

This project showcases real-time model serialization, UDP networking, and Qt GUI design without Qt Designer.

Store Application

A Qt-based desktop app that:

• Manages customers and inventory (books and magazines)
• Records transactions with date/time and quantity
• Tracks stock availability and prevents overselling
• Displays all transactions grouped by customer using a QTreeView
• Serializes the full model to XML using QXmlStreamWriter
• Broadcasts the XML model to the network via UDP (port 50000)
• Built with manual Qt widget setup (no .ui files)
• Features: splash screen, toolbar actions, help & about dialogs

Technologies & Concepts

• C++17, Qt 6.6, CMake
• Object-Oriented Design with parent-child memory management
• Custom serialization (Serializer pattern)
• Qt signals/slots (Observer pattern)
• Model-view architecture with QTreeView
• Multithread-safe UDP broadcasting and message handling

Build Instructions

Prerequisites

• Qt 6.x with CMake support
