A Framework for Pygame UI Elements

💡 PyNodle: A Pygame-Based Node Editor Framework

PyNodle is a modular, event-driven framework built on Pygame designed for creating node-based editors and visual programming interfaces. It provides all the necessary low-level components—from a robust UI manager and specialized widgets to a smooth Bézier curve drawing utility—to quickly prototype and build graphical programming tools.

✨ Features Overview

• Hierarchical UI Management: The UIManager handles element layering, rendering order, and ensures input blocking (only the top/active element, like a dragged node or a text input, receives events).
• Intuitive Event Handling: The Events class abstracts raw Pygame events (mouse clicks, double-clicks, wheel scroll, keyboard input) into simple, clean state variables.
• Specialized UI Widgets: Includes complex, ready-to-use components like UITextInput (with key repeat and validation), UIDropDown, UIMenuBar, and an UIColorPicker.
• Customizable Aesthetics: The separation of logic (UIElement) and visuals (UXElement/UXWrapper) allows for easy theme changes and custom component rendering.

🛠️ Installation and Setup

Prerequisites

You need Python 3.x installed.

Dependencies

PyNodle requires Pygame and NumPy (used for array manipulation in the color picker and potentially other areas).

pip install -r requirements.txt

🚀 Usage and Extending

The application's core logic runs in app.py. The UIManager (UIM) manages every component you create.

Implementing Custom Interactions

All custom components should inherit from UIElement and override the appropriate callback methods.
