Text:
- Ranged text access in code points (length, range, line bounds) that
never copies more than requested, plus a text revision (document UUID
and modification) so UIA and macOS cache their UTF-16 copies.
- Report document edits as exact change records, up to four per widget
and frame, then collapse to one whole-text change. Resets, loads and
document swaps report a whole-text change.
- The removed text is available only while an edit is being notified
(TextDocument::getNotifiedRemovedText()); DocumentContentChange stays
{ range, text }, so queued records (LSP) copy nothing extra.
- Suppressed text changes are keyed by node ref, so a document shared
with another window still reports its edits.
- UITextView reports NameChanged; UITextInput overrides onTextChanged()
to report ValueChanged.
Relations, live regions and shortcuts:
- aria-labelledby, aria-describedby and aria-live (API and CSS). Ids a
client has read are remembered; renaming, adding or removing their
widgets notifies the dependents. setId() copies the old id only when
it is remembered.
- Live regions and UISceneNode::announceForAccessibility(). A newer
change from the same widget replaces its pending announcement, and
hidden sources are dropped.
- Menu item shortcuts (std::string text and key) exposed as AT-SPI key
bindings, the UIA accelerator key and macOS command characters.
- ScrollTo for anything inside a scroll view
(UIScrollView::scrollIntoView()). Icon-only buttons are named from
their tooltip.
Dormant path (no client attached):
- Widget notifications are inline: one relaxed atomic load of a
process-wide count of active root scenes, no call.
- Scene destruction and scene or host changes never create a manager.
Without a client, notify() queues nothing and widget deletion does
not register parents to announce it. While only the root has an
identity, deletion skips the ancestor walk unless a remembered
relation target may be affected.
- When the last client disconnects, model-view sources release their
queried rows. Persistent handles count their registrations, so
handles held elsewhere survive (PersistentModelIndex::release()).
- Spin boxes no longer hide their input explicitly, and
AccessibilityProperties shrinks from 144 to 136 bytes.
Backends:
- AT-SPI: object:announcement, word and line granularity, ranged
reads, SetTextContents reported as its minimal diff. Watch
disconnects per client (NameOwnerChanged arg0 plus a non-blocking
NameHasOwner check) instead of for every bus name. Without a scene
thread pool, initialize on a detached thread that shares ownership,
so teardown never waits on D-Bus timeouts.
- UIA: notification events (resolved at runtime, Windows 10 1709+),
text ranges served from the revision cache, and a per-frame provider
drain that skips the lock when nothing is queued.
- macOS: announcements, a UTF-16 text cache per revision, and command
key attributes.
- EEPP_ACCESSIBILITY_TRACE=1 logs client activity transitions.
Fixes:
- UICodeEditor::isType() no longer dispatches to a subclass's
getType(), so a UITextEdit is a code editor again.
- ecode: dropped files open only in document editors, not in other
code editors such as a commit message box.
Tools, tests and docs:
- Widget inspector: role names, shortcut, relation and live rows, and
an accessibility audit (unnamed controls, broken relations).
- Accessibility example: live status, an icon-only button, and edit and
reset actions that test_atspi.py checks end to end.
- Regression tests for text records, relations, live regions,
disconnect and reconnect, scene lifecycle and id changes.
- Add the AccessibilityDormant benchmark (C++ new/new[] counted on the
measuring thread) and benchmark_accessibility_dormant.py, which fails
on missing measurements and compares against other builds with
--compare LABEL=PATH.
- Document the dormant-path rules, what survives a disconnection, and
the remaining platform limitations.
macOS:
- Check each notification against a hash set of (event, element,
related element) instead of scanning the whole pending queue. The
ordered queue still drives delivery, so a burst of distinct events
(e.g. 10,000 label changes) stays linear. Created/Destroyed are never
de-duplicated.
- Track the pending focus change by its index instead of scanning for it.
Core:
- SceneManager::update: also bound the loop by the live scene count, so
a scene removed during the pass can't cause an out-of-range read.
- Accessibility setters (role, label, description, hidden) return early
on unchanged values. Re-applying CSS no longer allocates the
properties block or notifies clients.
API cleanup:
- Remove AccessibilityRelation, AccessibilityRelationInfo and
AccessibilityNodeInfo::relations. Nothing populated them. Remove the
inspector row and the macOS linked-elements attribute that read them.
AT-SPI GetRelationSet still answers with an empty set.
- Drop unused includes in uiroot.cpp and accessibility.hpp.
Docs:
- Architecture guide: UIA and macOS queue events until update(); AT-SPI
emits right away except for per-frame text diffs. Describe each
backend's per-frame batching, including the macOS de-dup.
Tests:
- Add UnchangedAccessibilityPropertiesStaySilent.
CI fixes for the previous commit:
- Windows: announce one BoundsChanged on the window root when the scene
resizes, so UIA raises LayoutInvalidated again. Widgets still do not
report their own bounds changes.
- macOS: collapse identical pending notifications per element within one
update, so one text selection change posts a single
AXSelectedTextChanged. Created/Destroyed keep every occurrence, in order.
- MinGW: link the UIA test harness with -municode and uuid, which fixes
the nightly MinGW build.
Backends:
- Split the AT-SPI backend into a private header plus connection, events,
tree/marshalling and method files. Break the 600-line D-Bus dispatcher
into one handler per interface.
- Split the UIA backend into a private header plus core, element provider
and text range files.
- Share hasState/hasAction in accessibilitybackend.hpp instead of three
per-backend copies.
CI and docs:
- Run test_atspi.py --multi-window on Linux: closing a secondary window
while an AT-SPI client stays connected.
- Add docs/articles/uiaccessibilityarchitecture.md (layer map, files,
invariants, per-backend layout, common tasks, test matrix) and link it
from the articles index and the accessibility guide.
- Add a unit test for the single layout notification on scene resize.
Teardown and identity:
- Detach native backends before scene children are destroyed and clear
mRoot afterwards, fixing a use-after-free when an AT-SPI client is
connected while a window closes.
- Invalidate a deleted widget's subtree once, top-down, before OnClose
handlers run (NODE_FLAG_DESTROYING). Descendants never walk into
destroyed parents, and deleted identities cannot be re-registered.
- Closing scenes expose no accessibility manager through either accessor.
- Deleting widgets no client has seen allocates no identity and emits no
events.
- Ignore events from widgets not yet attached to a scene.
Events:
- Keep the order of state and structural events; coalesce only adjacent
query-again hints.
- Stop emitting per-widget BoundsChanged; bounds are queried on demand.
- Report the Focused state and keyboard focus only on the projected focus
owner, through a shared helper used by both paths.
Model views:
- Lazy child count and child queries, cached sibling indexes, selection
and hit testing without enumerating rows.
- Row identities follow inserted and removed rows; removed rows are
pruned from native wrapper caches.
- Expose the active cell editor as the child of the row or cell it edits.
AT-SPI:
- Correct state bits (EXPANDABLE/EXPANDED, SENSITIVE, CHECKABLE,
SELECTABLE, READ_ONLY, SINGLE/MULTI_LINE, SELECTABLE_TEXT) and the
password-text and panel roles.
- Emit text-changed insert/delete, caret-moved and selection-changed
events, diffed once per frame. Support line granularity,
SetCaretOffset and selection editing.
- Track clients by bus name so the active flag clears on disconnect.
- Fix the I/O thread busy-spin and stranded dispatch backlog, flush
queued signals, and type-check Properties.Set values.
UIA:
- Raise focus only for the focused element.
- Defer UiaDisconnectProvider out of widget destruction.
- Keep providers alive for in-flight cross-thread requests.
- Reject unknown interfaces without a UI-thread round trip.
- Require window-specific client activity.
macOS:
- Avoid repeated full node info builds.
- Use sibling indexes and lazy child access.
- Fix label/value deduplication for list items.
Tests and docs:
- Add regression tests for focus ownership, teardown, event ordering,
lazy model identities, nested scenes and cell editors.
- Extend the AT-SPI validation scripts and document the current
performance characteristics and limitations.
- Prevent dense-map iterator invalidation during widget deletion.
- Invalidate widget and model references when scene ownership changes.
- Expose nested-scene controls through the host accessibility manager.

- Support segmented keyboard editing, numeric entry, ISO paste, configurable
steps, bounds, empty values and independent seconds/milliseconds display.
Default time display to hours and minutes while preserving stored precision.
- Add day/month/year calendar navigation and a combined date-time popup with
time steppers, live configuration updates and scoped event connections.
- Add Breeze and fallback theme styles with CSS-defined SVG icons, dp sizing,
font-aware calendar dimensions and muted read-only/disabled controls.
- Map HTML date, time and datetime-local inputs to native controls with strict
value sanitization, min/max/step/required/readonly/disabled handling,
constraint validation and normalized form serialization.
- Provide private light HTML control defaults and intrinsic temporal sizing;
prevent author CSS from styling anonymous implementation parts.
- Share popup placement and visibility helpers across pickers, dropdowns and
trigger/cursor menus while retaining cascading-menu placement rules.
- Fix fractional grid wrapping and input cursor bubbling over child buttons;
notify and refresh styles when editing permission changes.

and unsaved source content when navigating back.
- Refresh the README around eepp's GUI framework and document the new APIs.
- Remove the fixed Markdown code font size and add regression coverage
- Clamp selection coordinates independently so horizontal dragging preserves
the selected row. Use the mouse event's Y coordinate against the terminal's
vertical bounds, including padding, and retain unclamped coordinates during
periodic updates outside the window.
eepp framework:
- Add shared cookie jars to UISceneNode and UIWebView, plus versioned
CookieManager persistence, domain clearing, and locking in hasCookie().
- Follow HTTP 303 redirects and merge same-host redirect cookies as
name/value pairs without forwarding Set-Cookie attributes.
- Include Cookie headers in document cache keys while preserving static
resource reuse as cookies change.
- Submit HTML forms with an empty action to the current document URL.
- Extend NavigationRequest with source, mouse buttons, modifiers, and
navigation target; anchors forward this context to the scene.

and explicit new-tab requests, with current-view fallback if unhandled.
- Install the WebView navigation interceptor during construction.
- Dispatch middle clicks to the hovered node without moving keyboard focus.
- Add the clicked target to ContextMenuEvent so applications can extend
context menus through existing events.
- Parse HTML titles, emit TitleEvent, and fix onTitleChanged's payload cast.

- Support validated left, middle, and right clicks in the inspector
server and Python client.
ui_html example:

between sessions and open new tabs blank.
- Add Inspect, Clear Domain Cookies, Clear All Cookies, and contextual
Open Link in New Tab actions through menu event subscriptions.
- Open requested links in background tabs and synchronize navigation UI.
- Use document titles and 16dp favicons for tabs, cap width at 200dp,
and truncate long titles with ellipsis.
- Enable tab-bar visibility across split panes.
- Fixed: the selection rectangle now uses the visible password symbols instead of the original text.
Update HTML compatibility and inspector documentation and add regression
coverage for persistence, redirects, cache isolation, navigation, menus,
titles, favicons, password colors, split visibility, and scrolling.
Store native and inherited fallback values outside local styles, then restore them when state rules stop matching. Handle indexed properties across overlapping states and retain a serialized value when an inherited source disappears. Add rollback regression tests and update the CSS documentation
Focus and select the first process row when pressing Down in the search input. Pressing Up from the first row returns focus to search in both table and tree views.

Resolve relative links against the document URI before copying, and cover
Markdown and WebView behavior with tests.
Fix layout width policy serialization to use the widget's width.
Add an opt-in TCP/NDJSON inspector for running eepp applications. It
provides authenticated, UI-thread-safe access to windows, scenes, and
widgets, including nested WebView documents. The v1 protocol supports
queries, trees, properties, focus, input actions, watches, screenshots,
and composed batches with result references and deferred execution.
Add a standard-library Python CLI, protocol documentation, build
entries, and integration tests. The listener remains disabled unless
explicitly enabled.
Fix HTML compatibility issues found while debugging NewsBlur:
- Let explicit flex minimums, including min-width: 0, replace the
automatic content minimum.
- Measure flex lines against the container content box when padding
and explicit dimensions are present.
- Keep promoted positioned descendants of hidden ancestors out of
the paint list.
Allow each LineSeries to fill down to the plot’s bottom edge, using a translucent version of its line color by default or a custom fill color. Render overlapping fills beneath the strokes, document the new API, and demonstrate it in the charts example. Add coverage for blending, data gaps, and toggling fills.
Introduce UITextSelectionController to coordinate selection across independent
RichText owners while retaining RichText hit testing and painting. Support
forward and reverse dragging, nested content, gap hit testing, autoscroll,
plain-text copy, select-all, and context menus.
Enable UIRichText and UITextSpan selection by default. Add CSS user-select
semantics and the -webkit-user-select alias, while preserving the separate
text-selection capability flag.
Clear selection safely when owners or documents are destroyed, suppress link
activation after a selection drag, and add regression tests, documentation,
and an updated rich-text example.

across eepp UI apps, with valid environment values taking precedence
over application settings. Document and test the overrides.
- Add CPU, memory, GPU, and network charts with ten-minute history,
a 60-second view, clickable cards, and overall or per-core CPU views.
- Add Family Memory and Family Memory % to both process views. Use
proportional memory on Linux, count zero-memory zombies correctly,
and collect the data after the first frame without delaying it.

key encoding with support for alternate keys, event types, associated
text, and reporting all keys as escape sequences.
Forward key press, repeat, and release events through the terminal
worker while preserving legacy input behavior. Keep AltGr composition
distinct from Alt shortcuts and correlate SDL text events to prevent
missing or duplicated international-layout input.
Add protocol documentation and unit coverage for negotiation, state
transitions, modifiers, function and keypad keys, shifted input,
AltGr composition, repeats, releases, and duplicate suppression.
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.

Refactor of some examples, added a new hello world example but using UIApplication.
ecode: Fixed how it filters the `sbt`, `srt` and `sb` universal locator switches.
Fix a bug when initializing the LSP that provoked to not correctly send the initial commands.
Added `expand-text` to UIPushButton.
Added `setAcceptsDropOfWidgetFn` to externally control which widgets are accepted as droppable in UITabWidget.
Improved draw invalidation in UIStackWidget.
Hack auto-scroll in terminal for Windows 11.
Renamed ScrollViewType and made it global, properties are now `overlay` or `outside`.
Added a couple of goodies for the terminal mode (retain side panel configuration and restore it if no terminals are left).
Added a new UIMessageBox event: `Event::OnDiscard`, this will triggered when window is closed without confirmation (`Event::OnConfirm`). And now `Event::OnCancel` is only triggered when is manually cancelled (click the cancel button).
ecode: Greatly improved image viewing experience. Now you can switch images from the same directory with the mouse wheel, also zoom, translate and rotate the images, images open in a new tab by default but quick-preview can be activated in `Settings -> Window -> Quick Preview Images` (SpartanJ/ecode#96).
Fixed: Debugger gutter not drawing its background.
Fixed: horizontal scrollbar sometimes being visible on wrapped documents.
Updated CSS Specification documentation.
