Introduce observable and computed values, typed widget bindings, validation groups, UI properties, commands, and UI-thread delivery.
Add observable vector and list model support for incrementally updated collections, with filtering and source-row mapping.
Modernize the Flight Booker and CRUD examples and add focused data handling and collection examples demonstrating the new APIs.
Organize the UI binding headers under ui/databinding, expand test coverage for notification and lifetime semantics, and document API selection, validation, ownership, threading, and performance behavior.
- replace FontManager with per-ResourceScope FontService instances
- publish font factories into explicit or default resource scopes
- import default resources into UI scene scopes unless explicitly disabled
- keep related font faces strongly owned without hot-path weak_ptr locking
- add cached glyph advance queries without creating texture pages
- fix font picker preview ownership, cleanup, and rapid switching
- selectively evict TextLayout cache entries when referenced fonts unload
- document FontService, ResourceCatalog, and cache invalidation semantics
- migrate examples, tools, benchmarks, and tests to the scoped font API
- expand coverage for font ownership, texture release, and layout caching
Return shared handles from NinePatch creation and remove the process-wide
NinePatchManager singleton.
Extend ResourceCatalog with typed drawable-source ownership and expose
drawable publication, lookup, and removal through ResourceScope. Preserve
separate texture and drawable namespaces for direct typed lookup.
Give each UITheme its own resource catalog and have scene-owned theme
managers explicitly import and remove theme catalogs. Handle registered
themes and default-only themes without leaking stale resource visibility
between scenes.
Update theme loading, Engine teardown, platform source manifests, and
resource ownership tests for the catalog-based model.
Document that remaining singleton resource managers must migrate to
naturally owned catalogs and explicit scope imports instead of becoming
new process-global semantic namespaces.
Introduce WebResourceCache with partitioned sharing, per-document sessions,
navigation generations, leases, and canonical request keys.
Coalesce concurrent document, stylesheet, font, and image requests while
discarding stale navigation subscribers independently. Retain completed
resources with TTL/LRU and byte-budget policies, and periodically prune
expired unleased entries from UIWebView.
Route UISceneNode, UIWebView, UIImage, CSS background images, and remote
drawable resolution through the shared cache. Preserve ResourceScope entries
as explicit overrides and allow multiple WebViews to share a cache partition.
Keep image decode and texture replacement on the guarded graphics-thread
completion path. Exclude volatile Cookie and Referer values from cache
identity while preserving partition isolation and content-affecting variants.
Start TTL retention when the final document lease is released so Back/Forward
navigation can reuse resources regardless of how long the previous page was
open.
Avoid unstable pointers and iterators into unordered_dense storage when
tracking leases and pruning entries. Add ASan regression coverage for dense
map growth, navigation, eviction, partition isolation, request coalescing,
retry behavior, and cache retention.
Fully document cache partitions, sessions, generations, request identity,
ownership, threading, and maintenance behavior.
Add a scene-owned UI::DrawableResolver for resolving file, data, HTTP, and
named drawable references through each UISceneNode's current resource scope.
Move generic texture, atlas region, nine-patch, and sprite lookup into
Graphics::ResourceScope, preserving drawable resolution for pure Graphics
consumers without introducing a UI dependency.
Migrate UI images, sprites, menus, CSS parsing, and tests to the new resolver.
Resolve CSS icons through the requesting node's scene instead of the global
scene, preserving embedded-scene isolation.
Remove the obsolete DrawableSearcher API and update platform project manifests,
tests, and the shared-resource architecture plan.
