A comprehensive C++ library management application built with Qt, demonstrating advanced object-oriented programming concepts and design patterns.
See this link for a comprehensive and detailed project report
This application serves as a practical implementation of a library management system, showcasing:
- Object-oriented programming principles
- Polymorphism and inheritance patterns
- Qt framework integration
- MVC (Model-View-Controller) architecture
- Visitor design pattern implementation
- Run the build script:
./build.shThe application can be run in two modes:
- GUI Mode (default):
./build/bin/.../qt-library- CLI Mode (for testing backend business logic):
./build/bin/.../qt-library --cliThe CLI mode provides a simple command-line interface to test the core functionality without the graphical user interface.
The application follows a structured architecture with clear separation of concerns:
- Models: Data structures and business logic
- Views: User interface components
- Controllers: Application flow and state management
- Visitors: Implementation of the visitor pattern for type-specific operations
- CLI: Command-line interface components
- Database: Data persistence layer
The application's navigation flow is inspired by RESTful patterns commonly used in web applications (like Ruby On Rails web apps), adapted for a desktop GUI context:
| Action | View | View Transition |
|---|---|---|
| List all items | IndexView | → IndexView |
| Show item | ShowItemView | IndexView → ShowItemView |
| New item form | NewItemView | IndexView → NewItemView |
| Edit item form | EditItemView | ShowItemView → EditItemView |
| Create item | NewItemView | NewItemView → IndexView |
| Update item | EditItemView | EditItemView → IndexItemView |
| Delete item | ShowItemView | ShowItemView → IndexView |
This pattern provides a clear and intuitive way to navigate between different views while maintaining a consistent user experience.
- Complete CRUD operations for library items
- Dynamic form generation based on item type
- Fuzzy search functionality
- Type-safe item management
- Modern Qt-based user interface
- New item creation with dynamic form generation
- Item viewing and detailed information display
- Item editing functionality
- Delete operations
- Search capabilities with fuzzy-like matching
The application leverages several key design patterns:
- Visitor pattern for type-specific operations
- MVC pattern for clean architecture
- Signal-slot mechanism for Qt-based event handling
- Smart pointer management for memory safety
