windowscrollTox

windowscrollTox is a software library that provides a unified API for controlling scrollable regions within Windows-based applications. It aims to normalize scrolling behavior across different UI toolkits and rendering backends, enabling developers to implement smooth, programmable scrolling without writing toolkit-specific code.

Origins and purpose: The project grew from efforts to address inconsistencies among Win32, WPF, UWP, and WinUI scrolling APIs. Its goal is to offer a portable set of scroll operations, including absolute and relative scrolling, as well as smooth transitions that respect user preferences and accessibility requirements.

Features and API concepts: The library exposes a high-level interface for navigating scrollable areas, including scrollTo and smoothScrollTo operations, queryable scroll positions, and event hooks for onScroll. It supports vertical and horizontal axes, configurable animation curves, and pluggable backends to render the final scroll state in different runtimes. It also provides accessibility hooks, such as respecting reduced motion settings and announcing scroll position changes.

Architecture and implementation: Core logic is described as language-agnostic and designed to work with common host environments. The architecture emphasizes a small core alongside optional platform adapters that translate generic scroll commands into native API calls for specific toolkits. The project favors a minimal API surface, clear error handling, and testable behavior.

Status and licensing: The project is open-source and in active development, with documentation and community contributions ongoing. It is intended for developers building custom Windows UI components or automated UI testing workflows and aims to be interoperable across multiple Windows UI frameworks.
