plattformsOSUI

plattformsOSUI is a cross-platform user interface library designed to enable developers to build native-looking applications across desktop and mobile platforms from a single codebase. It provides a component-based API and a rendering backend that maps UI constructs to native widgets on Windows, macOS, Linux, iOS, and Android.

Architecture: The library uses a layered architecture with a core toolkit, platform adapters, and a widget set. Developers declare user interfaces using reusable components such as Button, Window, List, and Menu. A layout system provides responsive behavior and high-DPI scaling. The rendering backend maps the component tree to native widgets, and a theming system ensures consistent appearance across platforms, with built-in accessibility features.

Features: plattformsOSUI emphasizes performance, accessibility, and theming. It offers a declarative API, a flexible layout system, styling through themes, keyboard navigation, and assistive technology support. A plugin mechanism allows extension with custom controls, while a rich set of standard widgets accelerates common app patterns.

Platforms and distribution: It targets Windows, macOS, Linux, iOS, and Android, with experimental web rendering through a bridge. The project is open-source and distributed under a permissive license. Documentation, tutorials, and example applications accompany the release, and a package manager simplifies integration into existing projects.

Development and community: plattformsOSUI is maintained by a community-driven core team, with contributions from individual developers and organizations. Development takes place on public repositories, featuring issue tracking, code reviews, and continuous integration. The project encourages collaboration, code of conduct adherence, and transparent governance.
