A reusable and educational Xojo module demonstrating how to implement a hierarchical Listbox (TreeView-style structure). This project is both a learning tool and a ready-to-use component that you can easily integrate into your own Xojo desktop applications.
- Add, rename, and delete nodes dynamically
- Virtually unlimited levels of hierarchy
- Each node can display a custom emoji
- Data persistence via SQLite (included)
- Clear code structure and modular design
- Simple UI for interaction and demonstration
- Fully open-source under the MIT License
This project serves as a hands-on learning resource for:
- Understanding tree data structures
- Managing UI elements hierarchically in Xojo
- Using SQLite to persist user data
- Writing clean, modular, and reusable Xojo code
This project is not only educational — it's also designed for practical use.
If you're a developer or software professional building a Xojo desktop application that requires hierarchical data visualization, this module will save you hours of development. It provides a complete, ready-to-use system for managing a Listbox in TreeView mode, with support for:
- Adding, renaming, and deleting nodes
- Unlimited nesting depth
- Emoji support for node icons
- SQLite integration for persistence
By integrating this module into your project, you skip the complexity of building a custom tree system from scratch. The logic is cleanly encapsulated and easy to plug into existing projects, allowing you to focus on your application's core functionality while delivering a rich user interface component with minimal effort.
