dayu_widgets is a Python widget library for PySide2 and PySide6 (Qt for Python), inspired by Ant Design. It provides a comprehensive collection of reusable UI components including buttons, labels, tables, menus, dialogs, and more, all styled with a theme engine supporting light and dark modes. The library is particularly tailored for creative applications (VFX tools like Maya, Nuke, Houdini) and offers advanced features such as declarative data binding via MFieldMixin, mixin decorators for common behaviors (cursor, shadow, animation), and SVG icon caching with color replacement. The codebase is well-structured with chainable size/type methods and a centralized theme system, but shows medium technical drift due to reliance on the deprecated PySide2 and some fragile DCC-specific integrations. It is published on PyPI and includes CI/CD, examples, and limited tests.
