What this is

examples/lims_gallery implements ten real LIMS screens in ui/1 to find out what the declarative UI can and cannot express: a sample receipt, a sample list, a results worksheet, a review and sign-off, a plate layout, a stability study, an instrument console, an audit trail, an e-signature dialog and a scanner console. It has no backend: sample data lives in screen state. Each screen has a compact and an expanded layout, a recording-backend test and a Qt Quick render smoke at both widths. Green (#17784A) is the main colour.

Run it with morph_examples_client --app lims-gallery --ui=qt.

Every gap the screens hit is in examples/lims_gallery/design/gaps.md (G1–G56). The fixes landed in five framework batches, each designed and reviewed once (docs/superpowers/specs/2026-10-25-lims-gallery-batch-{b,c,d,e}-design.md). After each batch, the gallery dropped the workarounds that batch replaced.

The framework batches

A: defects and responsive layout.

• env.widthClass is set by every backend, measured in units.
• Exact decimals in progress and component numbers.
• forEach keeps its common properties.
• A splitter honours sizes, and close: self closes the enclosing dialog.
• One key order on every backend.
• Qt Quick:
  • the dialog, drawer and progress bar follow the theme;
  • read-only inputs look read-only;
  • table cells are sized by kind;
  • touch-sized controls when compact;
  • the head row wraps.

B: tables.

• A mono text role and a font.mono token.
• Column align and valign.
• A bound selection with Replace and Extend changes, reachable from the keyboard.
• A check-box select column.
• A selected push button.
• Sortable columns and the sort form.
• pageSize and page, and the slice function.
• The runs form.
• group heading rows.
• showHeader is read as the flag it is.

C: text, fields and small controls.

• Qt Quick draws document text as plain characters.
• Inline emphasis spans.
• Label-over-value pairs and toned values.
• The required mark after the caption.
• Help text, and a value's evaluation, under an input.
• A dialog and drawer description line.
• A group of inputs with a legend.
• A text input's unit, announced to screen readers.
• An outlined destructive button, an outlined badge and a segmented select.
• List entries of several lines.
• One application-wide date pattern.
• A focal scanner field.

D: layout, overlays and navigation.

• The client mounts the app document.
• Bound tab labels and choosing a tab from a command.
• surface as an expression.
• Focus resolves into switch cases and other rows.
• Pinned bars and scrollable pages.
• A stepper helper.
• Grid column tracks.
• A menu drawn as one button.
• Removable badges.
• The screen head's own menu, search and select.
• A dialog shown as a sheet on compact.
• navigate as a dialog that answers its opener.
• Navigation counts and a compact shell.

E: expressions and charts.

• Out-of-range list indexes read as null.
• A get form.
• One checked 128-bit rounding everywhere expr/1 rounds, so no saturated values.
• Half-up rounding.
• abs, sqrt, stdev and rsd, exact until one correct rounding.
• dateAdd.
• A chart node, drawn by every frontend, with colour-blind-safe series colours and a marker per series.

Closes #1046, #1047, #1048, #1049, #1050, #1051, #1052, #1053, #1054, #1055, #1058, #1059, #1060, #1061, #1062, #1063, #1064, #1065, #1066.

Not closed here: #1056 (env locale, platform and online are never set), #1067 (two default tones below 3:1 on the dark sidebar, weak evidence) and #1068 (a state declared any with an init takes the init's type; found by this PR's coverage tests and kept as a [!shouldfail] case).

Verification

Run on the branch's tip (linux-everything, clang, -Werror), Qt suites with QT_QPA_PLATFORM=offscreen:

• The full build: no warnings.

• morph_tests: 3360 cases, 3358 passed, 2 failed as expected (the replay-ledger negative control and the ui/1: a state declared "any" with an init takes the init's type #1068 case, both marked so).

• morph_qt_quick_tests 189 cases (also on Qt 6.8.1, which the ladder job uses), morph_tui_tests 367, morph_client_tests 38, lims_gallery_tests 54, gallery_tests and all ten render smokes: all pass.

• include/morph/ui branch coverage 92.57%, measured locally with clang 21.

• qmllint (qt_quick_qmllint) passes.

• Doxygen with warnings as errors passes.

• clang-format 22 over every tracked C++ file: no differences.

• 54 conformance cases and 16 layout cases, run by the recording backend, Qt Quick and the TUI.

• Every new test has a control: the feature was broken, the test was seen to fail, and the feature was restored.

• clang-tidy 22 was run on changed lines in include/ and src/ (Qt sources with a local clang-tidy, because the tidy container has no Qt).

• Not run locally: MSVC, GCC 15 -O3. The new looks were checked through grabs and the render smoke only.

Known follow-ups

• The plate's well grid uses stretch tracks, and on Qt Quick at 1280 × 900 "STD1" is cut to "S…". Whether stretch tracks should take their widest cell's width is a framework decision.
• stepper cannot pin its footer, so the stability screen's Continue button scrolls on compact.
• A check-box toggle and a select choice now mark their field touched, so a required group's message shows under the default policy.

The run's tracker and handoff note are in examples/lims_gallery/design/ (status/, next.md).
