Fluxent

The Windows Host for Project Xent, written in C23 over Win32, Direct2D, DirectWrite, DirectComposition, and pure-C WinRT bindings from cwinrt.

Applications use the standard XTK control protocol. Fluxent does not expose a second flux_create_* control family or a renderer-plugin ABI.

Features

• atomic XtkBatch Host with generation-checked controls, typed properties, normalized events, transactional Components, and typed Providers;
• immutable Xent display-list record/replay with private built-in renderer metadata and resource interning;
• DirectWrite measurement/rendering, grapheme-aware editing, IME composition, selection, undo, and clipboard integration;
• DirectManipulation and Composition scrolling;
• UI Automation, focus/capture/routing, system accent, light/dark themes, NumberBox globalization, popups, menus, tooltips, and window backdrops;
• declarative flux_run and direct imperative XtkScene/XtkHost entry points over the same retained controls.

Controls

The generated XTK catalog is the source of truth. It includes text and image, buttons and split/menu variants, toggles, value controls, text editors, navigation, TabView, dialogs and teaching tips, virtualized list/grid/items/tree controls, scrolling and pull-to-refresh, status controls, and layout containers.

The declarative and imperative galleries exercise the same pages and behavior.

Build

xmake
xmake test
xmake run fluxent_gallery_decl
xmake run fluxent_gallery_imp

FLUX_USE_COMPOSITION=1 selects the Composition path; otherwise Fluxent uses the Direct2D path. The full gate includes both Gallery models, control behavior, Host transactions, display-list ownership, DirectWrite measurement, IME, virtualization, allocation failures, and degraded rendering.

Requires Windows 10 1903+, xmake, and a C23 compiler.
