GUI Library for Python Arcade

This project targets to offer simple to complex ui elements to use in games and software written with the Python Arcade library.

Some UI components were copied over to adjust and fix them.

This project could also end up in a PR to integrate within Arcade.

Basic Components

UIView

Central class to manager the ui components. Converts on_ callback functions into events, so that UIElements just have to contain one method to interact with user input.

UIElement

A general interface of an UI element.

Examples

Examples providing an overview of features, there will be dedicated documentation soon.

• UILabel
• UIButton
• UIInputBox
• Example with ID

Screenshots

  • Concept
    • UIManager manages every interaction, new elements get the UIManager on creation
    • Elements create events and hook into pygames event system
    • Themes can be read from JSON files

Ideas

• Create own implementation
• Build adapter for PyGame GUI
