From 3e82dbaa40fafdb60855a86d68e886827db61e1c Mon Sep 17 00:00:00 2001 From: Sebastian <53254078+cofade@users.noreply.github.com> Date: Fri, 22 May 2026 08:15:44 +0200 Subject: [PATCH 01/26] Migrate to PyQt6 and run SAM/DINO inference in-process (#4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * chore: Add PyQt6 + Torch coexistence smoke test (Phase 0 gate) Validates the central hypothesis of the upcoming subprocess-removal work: that PyQt6 sidesteps the WinError 1114 DLL load-order conflict on Windows + Python 3.14 that motivated sam_worker.py / dino_worker.py (see ADR-011). Run manually before deleting any worker code. Exit code 0 unblocks Phase 2 of the PyQt5 -> PyQt6 + in-process inference migration. https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL * feat: Migrate from PyQt5 to PyQt6 (Phase 1 of in-process inference PR) End-to-end migration of the GUI binding. 34 files, ~360 lines changed. All 65 tests still pass on PyQt6 6.11; the full app constructs and renders headlessly via QT_QPA_PLATFORM=offscreen. What changed ------------ - Dependency pins: PyQt5>=5.15 -> PyQt6>=6.7 (requirements.txt, setup.py) - Bulk import rewrite: `from PyQt5...` -> `from PyQt6...` (28 files) - Symbol relocations: * QAction moved from QtWidgets to QtGui (annotator_window.py) * QDesktopWidget removed -> QGuiApplication.primaryScreen() (snake_game.py) - Enum namespacing (Qt6 requires fully-qualified names everywhere): * Qt.AlignmentFlag / MouseButton / KeyboardModifier / Key * Qt.PenStyle / BrushStyle / CursorShape / GlobalColor * Qt.WindowType / WindowModality / FocusPolicy / TransformationMode * Qt.ItemDataRole / ItemFlag / ContextMenuPolicy / ScrollBarPolicy * Qt.TextFormat / TextInteractionFlag / MatchFlag / CheckState * QMessageBox.StandardButton / .Icon / .ButtonRole * QDialog.DialogCode, QFileDialog.AcceptMode / FileMode / Option * QAbstractItemView.SelectionMode / SelectionBehavior / EditTrigger * QHeaderView.ResizeMode, QSlider.TickPosition * QPainter.RenderHint, QImage.Format.Format_* * QDialogButtonBox.StandardButton / .ButtonRole * QKeySequence.StandardKey - Modern event API in image_label.py: event.pos()/.x()/.y() -> event.position() returning QPointF end-to-end. Scrollbar setValue() takes int() of the QPointF delta (the boundary). - Removed dead workaround in annotator_window.py: clearing WindowContextHelpButtonHint from dialog flags. Qt6 already suppresses this; the flag itself was removed. - exec_() -> exec() in main.py entry point. - CI: add libegl1/libgl1 to the Linux apt-install list (Qt6 needs them). - Docs: CLAUDE.md, README.md, docs/02_architecture_constraints.md updated to reflect PyQt6 and the relaxed Linux support story. Not touched ----------- - sam_worker.py, dino_worker.py, sam_utils.py, dino_utils.py subprocess pattern (Phase 2, gated on Win+Py3.14 validation). - exec_() call sites outside main.py (still work as deprecated alias). https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL * feat: Remove subprocess workers, run SAM/DINO in-process with QThread wrapping Phase 2 of the PyQt6 migration. The DLL conflict that motivated the subprocess workers (ADR-011) no longer applies under PyQt6, so the ~1-2 s subprocess spawn per inference is gone, and models stay cached across calls. What changed ------------ - Deleted sam_worker.py (288 lines), dino_worker.py (231 lines), tools/check_worker_isolation.py (134 lines). - Rewrote sam_utils.py end-to-end: * SAMUtils inherits QObject, caches the Ultralytics model in self._model * change_sam_model() loads eagerly (on worker thread, UI stays alive) * apply_sam_points / apply_sam_prediction / apply_sam_predictions_batch all run inference on a QThread via the new _run_sync helper * Lazy import of torch/ultralytics keeps app startup snappy * Added unload() for future Tools-menu memory release - Rewrote dino_utils.py with the same pattern (DINOUtils as QObject, model cached across calls, transformers lazy-imported). - Added _run_sync: spawns a QThread, pumps the calling thread's QEventLoop until done. Public API stays synchronous so the existing call sites in annotator_window.py work unchanged. UI events (timers, redraws, progress dialog cancels) keep flowing during the wait. - Removed the stale "If you are on Python 3.14, PyTorch may not yet be fully supported" message in change_sam_model error path. - utils.py docstring: drop sam_worker reference. Docs ---- - ADR-011 marked Superseded, with pointer to ADR-013. - New ADR-013 documents the in-process + QThread decision, the latency win, and the trade-offs (re-entrancy via QEventLoop pump, no more crash isolation). - arc42 docs/05_building_block_view.md, docs/06_runtime_view.md, docs/12_glossary.md updated to drop subprocess wording. - CLAUDE.md SAM Integration section rewritten. Verification ------------ - 65 tests pass (pytest, QT_QPA_PLATFORM=offscreen). - Full app constructs and renders headlessly. - _run_sync round-trip verified end-to-end against a 0.3 s sleep. - Phase 0 PyQt6+torch+transformers+ultralytics coexistence smoke test passes on Linux+Py3.11. Windows+Py3.14 verification is the user's responsibility before this PR ships. https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL * docs: Require senior reviewer to run in foreground, not background The quality gate is blocking by design — the next steps (address P0s, push, open PR) depend on its findings. Backgrounding it just defers the work and risks shipping unreviewed code. https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL * fix: Address senior reviewer P0/P1 findings on PyQt6+in-process PR P0 — correctness ---------------- - _InferenceThread.run no longer swallows exceptions. Stores them on the thread instance; _run_sync re-raises on the calling thread. Silent model-load failures previously showed up as "No mask matches" / "No detections" dialogs with no way to diagnose. (sam_utils.py) - Added _inference_in_flight module flag + InferenceBusyError. The earlier QMutex draft would have deadlocked: same-thread re-acquisition of a non-recursive mutex hangs, and a recursive mutex would defeat the whole serialization point. A flag with an explicit exception surfaces re-entry instead of corrupting the model with concurrent .forward() calls. (sam_utils.py) - Added _sam_inference_in_flight guard in annotator_window.apply_sam_prediction — the SAM debounce timer can fire while a previous inference is pumping inside _run_sync; the guard skips the re-entrant call so the next click + debounce restart issues a fresh inference with the up-to-date point set. P1 — should-fix --------------- - dino_utils._detect_blocking no longer shuffles the model CPU<->GPU on every call. Moving a 1.9 GB DINO base over PCIe was wiping out the in-process caching gain the whole PR was meant to deliver. - change_sam_model now flips current_sam_model AFTER successful load, not before. On load failure the state stays consistent. - _qimage_to_numpy always returns a fresh copy. The fallback path was particularly broken: the converted QImage was local, would go out of scope at return, and the worker thread's numpy buffer would have aliased freed memory. - Updated misleading dino_utils.detect comment about marshaling — the safety actually comes from the .copy() inside _qimage_to_numpy, not from where it runs. - ADR-001 marked Superseded with pointer to new ADR-014. - New ADR-014 documents the PyQt5->PyQt6 migration decision. - Updated ADR-013 consequences to honestly describe the re-entrancy guards (replaced the "acceptable for now; revisit if users hit it" hand-wave the reviewer specifically called out). - docs/01_introduction_and_goals.md, docs/05_building_block_view.md (ASCII diagram), docs/06_runtime_view.md (app.exec_() typo) all updated for PyQt6. - CLAUDE.md: Testing Checklist no longer references deleted sam_worker /dino_worker; senior-reviewer agent prompt no longer references deleted check_worker_isolation.py. - .claude/agents/senior-reviewer.md retargeted from PyQt5 -> PyQt6 and rewritten to check ADR-013 re-entrancy guards instead of ADR-011's retired subprocess isolation. P2 — opportunistic ------------------ - tools/check_pyqt6_torch_coexistence.py now constructs a QApplication after importing torch. Pure import alone does not load Qt's native platform plugin (qwindows.dll on Windows) — which is the actual site of the historical WinError 1114. The previous green result was a false positive on the strictest test. - CI matrix gains Python 3.13. ADR-013 claims PyQt6+torch coexist on modern Pythons; this adds CI evidence (Py3.14 still manual via the coexistence script — pip wheels not yet broadly available). - CI apt-install list deduped (libxcb-cursor0 was listed twice). Verification ------------ - 65 tests pass. - Smoke-tested both fixes: exception propagation works (boom() raises ValueError out of _run_sync); re-entry detection works (timer-driven inner call raises InferenceBusyError while outer is pumping). - coexistence script with QApplication construction passes end-to-end on Linux+Py3.11. https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL * fix: Address second-pass reviewer findings on PyQt6 PR P0 — correctness (regression unblocked by the first round's fix) ---------------------------------------------------------------- - annotator_window.py: import traceback at module level. The except block at the DINO call site (line 3022 pre-edit) referenced traceback.print_exc() without the module being importable in scope. Before the previous fix dino_utils.detect() returned None on error so the except was rarely entered; now it raises for real, so the NameError was about to start firing and leave the detect buttons permanently disabled with no user-visible dialog. P1 — should-fix --------------- - annotator_window.apply_sam_prediction now catches inference exceptions. The slot is driven by a QTimer; before this patch a CUDA OOM or InferenceBusyError would fall out into PyQt6's default unhandled-slot handler (stderr only). InferenceBusyError is suppressed silently (defense-in-depth alongside the call-site flag); other exceptions show a critical QMessageBox. - Same wrapping added to the unprotected SAM-batch calls inside both DINO flows (single image at line 3063, per-image loop at 3170). - Wired SAMUtils.unload() and DINOUtils.unload() to a new Tools menu entry "Unload AI Models (Free GPU Memory)". The DINO CPU<->GPU shuffle was removed in the previous round, which removes the automatic between-call free; this gives users on constrained GPUs a manual recovery path. - Bumped version 0.8.12 -> 0.9.0 in setup.py and __init__.py to signal the binding change (PyQt5 -> PyQt6) and the in-process inference rework. Anyone reading the wheel changelog now sees the binding switch in the version. - docs/05_building_block_view.md SAMUtils block rewritten to match the actual class shape (sam_model -> _model, qimage_to_numpy is a module-level helper not a method, _run_sync added). - Deleted PYTHON314_SETUP.md — it described the migration as future work, in the present tense, with the now-retired DLL workaround as a known issue. Easier to delete than keep coherent. P2 — cleanup ------------ - Dropped the unused `import traceback` in sam_utils.py (_InferenceThread captures exceptions on the instance now; no printing inside the worker). - The "No mask generated." batch fallback now builds a fresh dict per bbox via list comprehension instead of `[d] * N` (avoided shared-reference footgun). - Removed the dead `qimage_to_numpy` method on ImageAnnotator — module-level `_qimage_to_numpy` in sam_utils superseded it. - Folded the local `import traceback` inside `add_class`'s except block into the module-level import. Architectural belt-and-braces ----------------------------- - Added an assert at the top of `_run_sync`: the function MUST be called from the GUI thread. The `_inference_in_flight` flag is a plain global, not protected against cross-thread access — if a future contributor drives inference from a worker thread it becomes a true race. The assert is the tripwire. Reviewer flagged this as the kind of constraint that gets violated six months later when nobody remembers the design. Verification ------------ - 65 tests still pass. - Exception propagation and re-entry detection both re-tested in the full-app context — outer call returns 'done', timer-driven inner call raises InferenceBusyError, both as designed. - App constructs and renders headlessly. https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL * fix: Third-pass reviewer findings (TESTING.md + assert tripwire) P1 -- - TESTING.md: removed the "Known Issues — Python 3.14 + PyTorch Compatibility" section (the WinError 1114 it described is gone with the PyQt6 migration), removed the "Milestone 1.2: PyQt6 Migration" future-work entry (the migration is done), and added a brief "Headless Testing" section pointing at the CI deps list. Also bumped the CI Python row to mention 3.13. The file was not touched by earlier commits in this branch; the reviewer correctly pointed out that the branch is what made it wrong, so it's owed. P2 -- - Replaced the GUI-thread tripwire in sam_utils._run_sync with an explicit `if ...: raise RuntimeError(...)` instead of `assert`. `python -O` strips asserts; the tripwire was the kind of thing that would only matter once it had silently disappeared. Verification: 65 tests still pass. App still constructs. https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL * fix: Manual-testing fix pack on PyQt6 + in-process inference branch Closes user-reported regressions and rough edges discovered during Windows manual testing of PR #4. Covers crashes, UX bugs, and silent failures that the 65-test pytest-qt suite doesn't exercise. PyQt5 → PyQt6 mechanical migration gaps: - 15× .exec_() → .exec() across annotator_window, dino_merge_dialog, image_patcher, project_search, snake_game, stack_to_slices. The QMenu crash on right-click in the class list (annotator_window:4607) was the first user-visible casualty. - Missing `import traceback` in dino_merge_dialog.py. - F2 (Snake game) moved from keyPressEvent to QShortcut(ApplicationShortcut) so QTableWidget's in-cell-edit doesn't swallow it. Canvas — pan + zoom-to-cursor: - Pan now uses event.globalPosition() so the widget shifting under the cursor mid-drag doesn't absorb half the delta (former half-speed pan). - New cursor-anchored Ctrl+wheel zoom; post-zoom offset derived analytically from viewport().width() instead of the stale self.width() that's wrong on zoom-out before layout settles. DINO panel + detection: - Threshold column widths (88 px fixed) + setFrame(True) so values "0,25" / "0,50" are readable. - PhraseEditorPanel auto-reveals on class-add; row-0 phrase is now renamable. Removed the silent class-name re-prepend in get_phrases_for + _run_for_class so a renamed row-0 actually reaches DINO. - Auto-accept dropdown now honored by both single + batch paths. - "Detect All Images" extended to multi-dim image slices via _collect_dino_batch_work_items (was silently skipping stacks). - New _navigate_to_image_or_slice handles slice names in batch review; orphan results are popped instead of leaving a half-state. - temp_annotations is a single field — _refresh_dino_temp_for_current syncs it on every switch_slice / switch_image so masks don't bleed between slices. - Application-wide _DINOReviewEventFilter makes Enter / Escape work during review regardless of which widget has focus. ADR-015 documents the choice over QShortcut and force-focus alternatives. - dino_batch_results initialised in __init__; dropped 4 lazy-hasattr checks. - Verbose [DINO] / [SAM] diagnostic prints at decision points (un-gated per user request — print is the project convention). Multi-dim TIFF loading: - load_tiff reads tifffile.series[0].axes and maps Y→H, X→W into the app's dimension vocab. DimensionDialog defaults to these hints when ndim matches. - Explicit ndim 3-6 fallback table, plus generic ["T"]*(ndim-2) + ["H","W"] for ndim ≥ 7. The earlier default_dimensions[-ndim:] of a 4-element list silently degraded for 5D TZCYX inputs and produced 2560 one-row "slices". Tools → Unload AI Models: - Three-step recipe: model.cpu() → gc.collect() → empty_cache + ipc_collect + synchronize. Disclosure dialog now mentions the per-process CUDA context that survives unload. - Resets both SAM + DINO dropdowns and disables Detect buttons on unload. YOLO export: - image_paths lookup uses exact-key match first, substring fallback only (prevents "bee.jpg" matching "honeybee.jpg" by substring). - Diagnostic [YOLO v5+] / [YOLO v4] prints, warning when a class isn't in class_mapping. Dark mode: - Dark mode now on by default at startup. - Removed hardcoded #e0e0e0 / #f5f5f5 from ClassThresholdTable header and lbl_dino_status (they punched bright boxes into the dark sidebar). - Added QRadioButton / QCheckBox / QHeaderView / QTableWidget / QSpinBox / QDoubleSpinBox / QComboBox / QGroupBox rules to soft_dark_stylesheet so dataset splitter radio buttons + DINO panel widgets render with adequate contrast. - Annotated-slice highlight changed from light blue (173,216,230) to muted steel-blue (58,95,140) on dark mode. Docs: - ADR-015 added — application-wide event filter for DINO review. - Cross-cutting concepts gained sections for Pan + Zoom Reference Frames, Dark Mode No Hardcoded Colors Rule, Releasing Model GPU Memory, DINO Temp Annotations (lifecycle / event filter / batch / navigation / auto-accept), Multi-dim TIFF Axis Defaults, Export Format Filename Matching. - CLAUDE.md gained a "Patterns introduced in v0.9.0" index table pointing at the arc42 deep-dives so new contributors don't re-derive them.

No logic changes. Every move is a `git mv` followed by an import-path rewrite in the affected files. Subpackages introduced: - core/ constants, annotation_utils - widgets/ image_label - inference/ sam_utils, dino_utils - io/ export_formats, import_formats - ui/ default_stylesheet, soft_dark_stylesheet - dialogs/ 15 standalone dialog/tool windows (statistics, splitter, augmenter, registration, interpolator, patcher, dicom, snake, help, project_search, project_details, phrase editor, merge dialog, stack_to_slices, yolo_trainer, coco_json_combiner) Files staying at the package root: main.py, utils.py, annotator_window.py, __init__.py. The public API surface (ImageAnnotator, ImageLabel, SAMUtils, calculate_area, calculate_bbox) and the CLI entry points (digitalsreeni-image-annotator, sreeni) are unchanged. Tests updated for the new paths: - tests/integration/test_export_formats.py: import from io.export_formats - tests/unit/test_conversions.py: file-path loader points at widgets/image_label.py New tests/integration/test_smoke.py asserts the public API and that every internal module imports cleanly — the safety net for subsequent refactor phases. Result: 94 tests pass (47 unit + 18 integration + 29 new smoke). Phases 2–9 (controller extractions, ImageLabel signal decoupling, per-tool handlers, UI assembly extraction, docs) ship in follow-up PRs. --- src/digitalsreeni_image_annotator/__init__.py | 4 +-

Moves three self-contained method clusters out of the 5,900-line annotator_window.py into focused modules. ImageAnnotator keeps thin delegating methods so external callers (menu actions, signal connections, library consumers) keep working unchanged. New modules: - core/image_utils.py — pure NumPy/QImage helpers (no Qt main-window dependency): convert_to_serializable, normalize_array, adjust_contrast, convert_to_8bit_rgb, array_to_qimage. - ui/theme.py — theme + font-size application taking the main window as first arg: apply_theme_and_font, toggle_dark_mode, apply_stylesheet, update_ui_colors, setup_font_size_selector, on_font_size_changed, change_font_size. - controllers/io_controller.py — UI glue around the existing pure I/O format functions: import_annotations, export_annotations, save_slices. The format readers/writers themselves (io.export_formats, io.import_formats) are untouched. annotator_window.py shrinks from 5,900 to 5,476 lines (-424 lines, -7%). Dead imports of the stylesheet constants and the export/import format functions removed from the top of the file — they live with their new home modules now. No behaviour change. The .iap save/load schema is untouched (the delegating convert_to_serializable still produces the same JSON-ready dicts). ADR-013's in-process inference path is untouched. The is_loading_project guard remains in ImageAnnotator. Tests: all 94 pass (47 unit + 18 integration + 29 smoke). https://claude.ai/code/session_01QxGci8QYbXHtV6BpoBLfAU --- .../annotator_window.py | 460 +----------------- .../controllers/__init__.py | 0 .../controllers/io_controller.py | 338 +++++++++++++ .../core/image_utils.py | 74 +++ src/digitalsreeni_image_annotator/ui/theme.py | 68 +++ 5 files changed, 498 insertions(+), 442 deletions(-) create mode 100644 src/digitalsreeni_image_annotator/controllers/__init__.py create mode 100644 src/digitalsreeni_image_annotator/controllers/io_controller.py create mode 100644 src/digitalsreeni_image_annotator/core/image_utils.py create mode 100644 src/digitalsreeni_image_annotator/ui/theme.py diff --git a/src/digitalsreeni_image_annotator/annotator_window.py b/src/digitalsreeni_image_annotator/annotator_window.py index 9e8da65..9071f39 100644 --- a/src/digitalsreeni_image_annotator/annotator_window.py +++ b/src/digitalsreeni_image_annotator/annotator_window.py @@ -57,37 +57,23 @@ from shapely.validation import make_valid from tifffile import TiffFile +from .controllers import io_controller +from .core import image_utils +from .ui import theme from .dialogs.annotation_statistics import show_annotation_statistics from .dialogs.coco_json_combiner import show_coco_json_combiner from .dialogs.dino_phrase_editor import ClassThresholdTable, PhraseEditorPanel from .inference.dino_utils import DINOUtils from .dialogs.dataset_splitter import DatasetSplitterTool -from .ui.default_stylesheet import default_stylesheet from .dialogs.dicom_converter import DicomConverter from .dialogs.dino_merge_dialog import show_dino_merge_dialog -from .io.export_formats import ( - export_coco_json, - export_labeled_images, - export_pascal_voc_bbox, - export_pascal_voc_both, - export_semantic_labels, - export_yolo_v4, - export_yolo_v5plus, -) from .dialogs.help_window import HelpWindow from .dialogs.image_augmenter import show_image_augmenter from .widgets.image_label import ImageLabel from .dialogs.image_patcher import show_image_patcher -from .io.import_formats import ( - import_coco_json, - import_yolo_v4, - import_yolo_v5plus, - process_import_format, -) from .inference.sam_utils import InferenceBusyError, SAMUtils from .dialogs.slice_registration import SliceRegistrationTool from .dialogs.snake_game import SnakeGame -from .ui.soft_dark_stylesheet import soft_dark_stylesheet from .dialogs.stack_interpolator import StackInterpolator from .dialogs.stack_to_slices import show_stack_to_slices from .utils import calculate_area, calculate_bbox @@ -785,20 +771,7 @@ def check_missing_images(self): self.prompt_load_missing_images(missing_images) def convert_to_serializable(self, obj): - if isinstance(obj, np.integer): - return int(obj) - elif isinstance(obj, np.floating): - return float(obj) - elif isinstance(obj, np.ndarray): - return obj.tolist() - elif isinstance(obj, list): - return [self.convert_to_serializable(item) for item in obj] - elif isinstance(obj, dict): - return { - key: self.convert_to_serializable(value) for key, value in obj.items() - } - else: - return obj + return image_utils.convert_to_serializable(obj) def save_project(self, show_message=True): if not hasattr(self, "current_project_file") or not self.current_project_file: @@ -1258,20 +1231,7 @@ def open_images(self): self.add_images_to_list(file_names) def convert_to_8bit_rgb(self, image_array): - if image_array.ndim == 2: - # Grayscale image - image_8bit = self.normalize_array(image_array) - return np.stack((image_8bit,) * 3, axis=-1) - elif image_array.ndim == 3: - if image_array.shape[2] == 3: - # Already RGB, just normalize - return self.normalize_array(image_array) - elif image_array.shape[2] > 3: - # Multi-channel image, use first three channels - rgb_array = image_array[:, :, :3] - return self.normalize_array(rgb_array) - - raise ValueError(f"Unsupported image shape: {image_array.shape}") + return image_utils.convert_to_8bit_rgb(image_array) def add_images_to_list(self, file_names): first_added_item = None @@ -1856,36 +1816,10 @@ def add_slice_to_list(self, slice_name): self.slice_list.addItem(item) def normalize_array(self, array): - # print(f"Normalizing array.

This PR covers Phase 3a: extracting project-lifecycle methods. Phase 3b will extract image/slice loading into an ImageController in a follow-up PR. The original plan called for both controllers in one PR. Splitting makes the diff reviewable: 19 project methods is already ~550 lines of moved code, and ImageController would have added another ~25 methods including the multi-dimensional image handling that touches TIFF/CZI loaders. New controllers/project_controller.py (548 lines) — ProjectController(QObject) owns the project lifecycle: - new_project, open_project, open_specific_project, backup_project_before_open, restore_project_from_backup - load_project_data (the .iap reader, including DINO config restore) - save_project (the .iap writer), save_project_as, auto_save - close_project - handle_missing_images, remove_missing_images, prompt_load_missing_images, load_missing_images, check_missing_images - update_window_title ImageAnnotator now holds self.project_controller = ProjectController(self) and keeps thin delegating methods for each so menu actions and signal connections continue to work unchanged. State (is_loading_project, backup_project_path, current_project_file, current_project_dir, project_notes, etc.) deliberately STAYS on the main window in this phase. The controller reads/writes them via self.mw.X. A future phase can migrate ownership; for now this is pure method relocation and reduces risk. The is_loading_project guard (ADR-required, prevents autosave during load) is preserved: auto_save() still checks self.mw.is_loading_project, open_specific_project still flips it around load_project_data(). Methods NOT moved in this PR despite appearing in the plan: - clear_all — touches ~30 state attributes across every controller's domain; deferred until after all controllers exist so it can be decomposed properly - closeEvent — Qt method override on QMainWindow, conceptually belongs on the main window Dead imports of datetime and shutil dropped from annotator_window.py since their only consumers moved out. annotator_window.py: 5,476 → 4,944 lines (-532, -9.7%).

From 857ea4898b4af67275fbb257fb0ab53263e1b543 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 22 May 2026 09:51:09 +0000 Subject: [PATCH 05/26] refactor: Extract ImageController from ImageAnnotator (Phase 3b) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Second half of Phase 3 in the modular refactoring. Completes the work started by ProjectController (PR #7) by giving image and slice loading / navigation its own home. New controllers/image_controller.py (869 lines) — ImageController(QObject) plus the DimensionDialog class (moved out of annotator_window.py top level since it is only used by process_multidimensional_image). Methods relocated to ImageController: Loaders: - load_image (extension dispatch) - load_tiff (with axes-hint detection from TIFF series metadata — the bugfix from arc42 for ndim>=5 TZCYX inputs is preserved verbatim) - load_czi - load_regular_image - load_multi_slice_image (orchestrates TIFF/CZI multi-slice loading) - process_multidimensional_image (dimension assignment dialog flow) - create_slices (per-axis slicing + progress dialog) Navigation / activation: - switch_image, switch_slice, activate_slice, activate_current_slice - update_image_list, update_slice_list, clear_slice_list - add_slice_to_list, setup_slice_list Image lifecycle: - open_images, add_images_to_list, update_all_images - remove_image, delete_selected_image, redefine_dimensions - display_image - is_multi_dimensional State (current_image, current_slice, slices, image_paths, image_slices, image_dimensions, image_shapes, all_images, image_file_name, etc.) deliberately STAYS on the main window — accessed via self.mw.X. Same deferral as Phase 3a; future phase may migrate ownership. ImageAnnotator now holds self.image_controller = ImageController(self) and keeps thin delegating methods for each so menu actions and signal connections continue to work unchanged. DimensionDialog moved with the methods that use it. The pre-fill from TIFF series axes and the ndim>=7 fallback ("T"*N + ["H","W"]) are preserved verbatim — those are the fixes from arc42's "ndim≥5 [-ndim:] slice bug" note. Dead imports of czifile.CziFile and tifffile.TiffFile removed from annotator_window.py since their only consumers moved into the controller. annotator_window.py: 4,944 → 4,122 lines (-822, -16.6%). Total reduction vs original master: 5,900 → 4,122 (-30.1%).

Phase 4b (DINO) and Phase 4c (YOLO) follow as separate PRs. New controllers/sam_controller.py (267 lines) — SAMController(QObject) owns the SAM tool lifecycle (magic wand, box, points), the debounce timer state machine, and the model picker dropdown plumbing. Methods relocated: - activate_sam_magic_wand, deactivate_sam_magic_wand - toggle_sam_assisted, toggle_sam_magic_wand - toggle_sam_box, toggle_sam_points - schedule_sam_prediction, apply_sam_prediction, accept_sam_prediction - change_sam_model ADR-013 invariants preserved verbatim: - `_sam_inference_in_flight` flag set BEFORE calling sam_utils, cleared in `finally`. - `InferenceBusyError` swallowed silently — next user click restarts the debounce. - `change_sam_model` blocks via _run_sync event-loop pump. State stays on the main window (consistent with Phase 3): - sam_utils, sam_inference_timer, _sam_inference_in_flight, current_sam_model accessed via self.mw.X - External readers (image_label.py:1007 reads main_window.sam_inference_timer; clear_all resets current_sam_model; the sidebar button enabling logic reads current_sam_model) keep working unchanged. The sam_inference_timer.timeout signal connection in __init__ still points at self.apply_sam_prediction — that's now the thin delegate that calls into the controller. Single extra call frame, zero behaviour change. Dead import of InferenceBusyError removed from annotator_window.py since the only consumer moved into the controller. annotator_window.py: 4,122 → 3,913 lines (-209, -5.1%).

Phase 4c (YOLO) follows. New controllers/dino_controller.py (796 lines) — DINOController(QObject) plus the _DINOReviewEventFilter class. Methods relocated: - Model picker plumbing: _resolve_dino_model_path, _on_dino_model_changed, _ensure_dino_model_downloaded, browse_dino_model, on_dino_class_row_changed, _build_dino_class_configs - Detection workflows: run_dino_detection_single, run_dino_detection_batch, _collect_dino_batch_work_items, _commit_dino_results, _store_dino_batch_results, _show_dino_batch_review, _navigate_to_image_or_slice, _refresh_dino_temp_for_current, accept_dino_results, reject_dino_results - Temp-class review (shared with YOLO predictions): add_temp_classes, has_visible_temp_classes, verify_current_class, accept_visible_temp_classes, select_first_primary_class, reject_visible_temp_classes, check_temp_annotations, remove_all_temp_annotations The _DINOReviewEventFilter (ADR-015) moves alongside its only caller. It still installs into the QApplication during ImageAnnotator.__init__; the installation continues to call accept_dino_results / reject_dino_results on the main window, which now delegate into the controller. Behaviour preserved. State stays on the main window (consistent with prior phases): dino_utils, dino_model_loaded, dino_custom_model_path, dino_batch_results, all DINO widgets (phrase panel, threshold table, model selector, batch mode combo, status label, browse row, detect buttons) accessed via self.mw.X. External readers (clear_all touches dino_model_loaded / dino_custom_model_path; load_project_data restores dino_batch_results via add_temp_classes; ImageController calls self.mw._refresh_dino_temp_for_current() from switch_image / switch_slice) keep working unchanged. Also fixes 4 dormant import bugs left over from Phase 1's file moves — local imports inside method bodies that weren't updated: - .dino_utils → .inference.dino_utils (in _resolve_dino_model_path) - .project_search → .dialogs.project_search (in show_project_search) - .annotation_statistics → .dialogs.annotation_statistics - .project_details → .dialogs.project_details These didn't fail tests because they only run when their containing method is called, but the first user trying to open the project search or project details dialogs would have hit ModuleNotFoundError. Dead imports of QEvent, QObject, and QProgressDialog removed from annotator_window.py since their only remaining consumers (the filter class and process_multidim) have already moved out. annotator_window.py: 3,913 → 3,194 lines (-719, -18.4%).

With this PR all three inference engines (SAM / DINO / YOLO) live in their own modules. New controllers/yolo_controller.py (539 lines) — YOLOController(QObject) plus the TrainingThread(QThread) class. Methods relocated: - Menu: setup_yolo_menu - Training data + model loading: load_yolo_model, prepare_yolo_dataset, load_yolo_yaml, save_yolo_model, load_prediction_model, initialize_yolo_trainer - Training execution: show_train_dialog, start_training, training_finished - Prediction: set_confidence_threshold, show_predict_dialog, run_predictions, predict_single_image, process_yolo_results State (yolo_trainer, training_thread, training_dialog) stays on the main window for consistency. ImageAnnotator.__init__ still sets yolo_trainer = None; setup_yolo_menu (delegated to the controller) is called from __init__ after the menu bar exists. Dead top-level imports removed from annotator_window.py: - cv2 (only used by process_yolo_results) - numpy (only used by process_yolo_results) - QThread, pyqtSignal (only used by TrainingThread, now in YOLOController) - QDoubleSpinBox (only used by show_predict_dialog) - LoadPredictionModelDialog, TrainingInfoDialog, YOLOTrainer (referenced by methods that moved) annotator_window.py: 3,194 → 2,757 lines (-437, -13.7%). Total reduction vs original master: 5,900 → 2,757 (-53.3%).

Phase 5b (ClassController) follows. This is the cluster ImageLabel mutates most directly via main_window.add_annotation_to_list(...), main_window.save_current_annotations(), etc. Phase 5 keeps the delegation pattern on ImageAnnotator so ImageLabel's call sites continue to work; Phase 6 will replace those with Qt signals. New controllers/annotation_controller.py (823 lines) — AnnotationController(QObject). Methods relocated (24): - COCO conversion: create_coco_annotation - List widget updates: update_all_annotation_lists, update_annotation_list, update_annotation_list_colors, update_annotation_list_with_sorted - Per-image cache sync: load_image_annotations, save_current_annotations - Sorting: sort_annotations_by_class, sort_annotations_by_area - COCO JSON load (independent of project save/load): load_annotations - Highlighting/selection: clear_highlighted_annotation, update_highlighted_annotations, highlight_annotation, highlight_annotation_in_list, select_annotation_in_list - Annotation numbering: renumber_annotations - Delete/merge/change-class: delete_annotation, delete_selected_annotations, merge_annotations, change_annotation_class - Tool commit paths: finish_polygon, finish_rectangle, add_annotation_to_list - Edit mode: enter_edit_mode, exit_edit_mode State stays on the main window (consistent with prior phases): - all_annotations, image_label.annotations - editing_mode, loaded_json, current_sort_method - annotation_list, merge_button, change_class_button widgets Dead imports of copy, json, shapely (MultiPolygon, Point, Polygon, unary_union, make_valid), and utils (calculate_area, calculate_bbox) removed from annotator_window.py — all consumers moved. annotator_window.py: 2,757 → 2,038 lines (-719, -26.1%). Total reduction vs original master: 5,900 → 2,038 (-65.5%).

The ImageLabel-mutates-ImageAnnotator cluster is now fully extracted — Phase 6 can wire the signal decoupling. New controllers/class_controller.py (422 lines) — ClassController(QObject). Methods relocated (14): - Selection: select_class, on_class_selected, update_class_selection, is_class_visible - Add/delete/rename/colour: add_class, delete_class, delete_selected_class, rename_class, change_class_color - List widget: update_class_item_color, update_class_list - Visibility: toggle_class_visibility - Context menu: show_class_context_menu - Slice-list colouring driven by per-slice annotations: update_slice_list_colors State stays on the main window: - class_mapping, image_label.class_colors, image_label.class_visibility - current_class - class_list, slice_list widgets - DINO widgets (dino_class_table, dino_phrase_panel) Minor robustness improvement: ClassController.delete_class accepts either a QListWidgetItem (the right-click context-menu path) or a class-name string (the orphaned delete_selected_class path). delete_selected_class is dead code in the codebase — nothing calls it — but the original delete_class(class_name) would have crashed with AttributeError on str.text() if the path were ever wired up. Dead imports removed from annotator_window.py: - traceback - QIcon, QColorDialog (only used by class methods that moved) - QGridLayout (was used only by the DimensionDialog → moved in Phase 3b) - QListWidgetItem (used only by class/annotation methods) - QCheckBox (no consumers left) - QInputDialog (only used by methods that moved) - QDialogButtonBox (only used by show_train_dialog → moved in Phase 4c) annotator_window.py: 2,038 → 1,669 lines (-369, -18.1%). Total reduction vs original master: 5,900 → 1,669 (-71.7%).

The orchestrator (ImageAnnotator) wires each signal to the matching controller slot in __init__ via _connect_image_label_signals(). What changed: - New widgets/canvas_context.py: narrow read-only view of main-window state for ImageLabel (paint_brush_size, eraser_size, current_class, class_id, class_mapping, is_class_visible, current_image_key, all_annotations, scroll_area, dialog_parent). - widgets/image_label.py: removed self.main_window field and set_main_window() method. Added 20 pyqtSignals covering annotation lifecycle, SAM, class, tool/UI state, navigation. All 50 main_window references replaced with self._ctx.() or self..emit(). - annotator_window.py: drops set_main_window call; constructs CanvasContext(self) after controllers are instantiated and connects every ImageLabel signal to a controller slot. Adds two thin slots: _on_tool_size_changed (brush/eraser size RMW) and _on_annotations_batch_saved (finalize paint/accept-temp batch). - controllers/annotation_controller.py: new replace_annotations() takes (image_key, per-class dict) for the eraser path; does the full replace + list update + save + slice-colour refresh atomically. - controllers/sam_controller.py: new cancel_sam_prediction() handles the Escape-during-sam_points timer-stop path. Invariants preserved: - v0.9.0 pan/zoom (event.globalPosition() for pan, viewport().width() for post-zoom offset). - ADR-013 SAM re-entrancy guard. - DINO temp_annotations single-field re-sync (untouched). - is_loading_project autosave guard (untouched). All 94 tests pass. https://claude.ai/code/session_01QxGci8QYbXHtV6BpoBLfAU --- .../annotator_window.py | 57 +++++- .../controllers/annotation_controller.py | 10 + .../controllers/sam_controller.py | 5 + .../widgets/canvas_context.py | 48 +++++ .../widgets/image_label.py | 171 ++++++++++-------- 5 files changed, 219 insertions(+), 72 deletions(-) create mode 100644 src/digitalsreeni_image_annotator/widgets/canvas_context.py diff --git a/src/digitalsreeni_image_annotator/annotator_window.py b/src/digitalsreeni_image_annotator/annotator_window.py index 77bf544..ae54646 100644 --- a/src/digitalsreeni_image_annotator/annotator_window.py +++ b/src/digitalsreeni_image_annotator/annotator_window.py @@ -53,6 +53,7 @@ from .dialogs.dino_merge_dialog import show_dino_merge_dialog from .dialogs.help_window import HelpWindow from .dialogs.image_augmenter import show_image_augmenter +from .widgets.canvas_context import CanvasContext from .widgets.image_label import ImageLabel from .dialogs.image_patcher import show_image_patcher from .inference.sam_utils import SAMUtils @@ -90,7 +91,6 @@ def __init__(self): self.image_label.sam_points_active = False self.image_label.sam_positive_points = [] self.image_label.sam_negative_points = [] - self.image_label.set_main_window(self) # Initialize attributes self.current_image = None @@ -141,6 +141,12 @@ def __init__(self): self.annotation_controller = AnnotationController(self) self.class_controller = ClassController(self) + # CanvasContext gives ImageLabel a narrow read view of main-window + # state.

docs/11_risks_and_technical_debt.md: mark "ImageLabel ↔ ImageAnnotator tight coupling" debt as Resolved and point at ADR-016. - docs/05_building_block_view.md: dependency diagram now shows ImageLabel emitting signals to ImageAnnotator and reading via CanvasContext (was: "references ──> ImageAnnotator (callbacks)"). - docs/09_architecture_decisions.md: new ADR-016 recording the signals+CanvasContext decision, rules for adding new traffic in either direction, and the synchronous-emit ordering / batch-save invariants the pattern depends on. - docs/08_crosscutting_concepts.md: new "Canvas Decoupling" section with the rules of the pattern (no back-reference to ImageAnnotator; use CanvasContext for reads; batch-save signal preserves O(1) save). - CLAUDE.md: "Adding a New Annotation Tool" step 5 referred to main_window.add_annotation() (which never existed and is misleading post-Phase-6). Updated to emit annotationCommitted with a pointer to ADR-016. P2 code cleanups: - Drop the `committed` / `had_annotations` guards in commit_paint_annotation and accept_temp_annotations — the original pre-refactor code emitted save_current_annotations() + update_slice_list_colors() unconditionally inside the same branch. Restores literal semantic equivalence with the pre-Phase-6 code as promised in the Phase 6 commit body. - Rename SAMController.cancel_sam_prediction → cancel_sam_debounce. The method stops the debounce timer; it does NOT abort an in-flight inference (the _sam_inference_in_flight guard handles that — ADR-013). The old name conflated the two. All 94 tests pass. https://claude.ai/code/session_01QxGci8QYbXHtV6BpoBLfAU --- CLAUDE.md | 4 +- docs/05_building_block_view.md | 4 +- docs/08_crosscutting_concepts.md | 51 ++++++++++ docs/09_architecture_decisions.md | 97 +++++++++++++++++++ docs/11_risks_and_technical_debt.md | 29 ++---- .../annotator_window.py | 2 +- .../controllers/sam_controller.py | 8 +- .../widgets/image_label.py | 9 +- 8 files changed, 171 insertions(+), 33 deletions(-) diff --git a/CLAUDE.md b/CLAUDE.md index ae5b906..93fdf39 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -68,7 +68,9 @@ See [Building Block View](docs/05_building_block_view.md) for detailed class doc 2.

ImageLabel keeps a thin dispatcher: mouse/key events route to the active handler; paintEvent calls active_tool_handler.paint_overlay() for in-progress state rendering. What changed: - New widgets/tools/{__init__, base, rectangle_tool, polygon_tool, paint_tool, eraser_tool}.py: 525 LOC across 6 files. Each handler subclasses ToolHandler (plain Python object, not a QObject) and emits back through ImageLabel's Phase 6 signals — no controller imports. - widgets/image_label.py: dropped start_painting / continue_painting / finish_painting / commit_paint_annotation / discard_paint_annotation + the mirror eraser methods + finish_polygon / cancel_current_annotation / finish_current_annotation / get_rectangle_from_points / draw_temp_paint_mask / draw_temp_eraser_mask / draw_current_rectangle. paintEvent's tool-specific branches collapse to a single active_tool_handler.paint_overlay() call. Mouse/key event chains collapse to dispatch calls. check_unsaved_changes iterates has_unsaved_state across the handlers. 1239 -> 963 LOC (-276). - Added image_label.active_tool_handler property and set_active_tool() with deactivate() lifecycle hook. - annotator_window.py: tool-button toggle paths switch from `image_label.current_tool = "X"` to `image_label.set_active_tool("X")` (6 sites). closeEvent unsaved-changes path now routes through the paint_brush / eraser handlers' commit() / discard(). - controllers/image_controller.py: switch_slice unsaved-changes path same routing update. - tests/unit/test_conversions.py: dropped the spec_from_file_location trick (relative imports inside widgets/ subpackage break it); plain import works now and the comment about torch dependency is stale — widgets/__init__.py is empty. Removed dead code (no readers anywhere): - ImageLabel.paint_mask + ImageLabel.eraser_mask fields - draw_paint_mask + draw_eraser_mask methods - Stale Qt imports (cv2, numpy, QApplication, QPolygon) State ownership (deliberate deviation from the original plan): Tool handlers contain only behavior, not state. Fields like current_rectangle, start_point, end_point, current_annotation, temp_point, drawing_polygon, drawing_rectangle, temp_paint_mask, is_painting, temp_eraser_mask, is_erasing stay on ImageLabel — AnnotationController.finish_rectangle / finish_polygon and other controllers still read mw.image_label.X directly. Moving state into the handlers would require a parallel controller refactor; left for a follow-up. Invariants preserved: - ADR-013 SAM re-entrancy: SAM logic stays on ImageLabel. - v0.9.0 pan/zoom: Ctrl-modifier branches in mouse events run before tool dispatch. - ADR-015 DINO event filter: temp_annotations + accept/discard stays on ImageLabel. - ADR-016 (Phase 6) signal contract: tools emit via self.label.X.emit(). - Polygon edit mode (editing_polygon + handle_editing_click + handle_editing_move + draw_editing_polygon) stays on ImageLabel as a modal state orthogonal to tool selection. - Eraser commit OpenCV polygon-cutting moved byte-for-byte.

Narrowed has_unsaved_state to len > 2; commit() now matches. - widgets/image_label.py: paintEvent now iterates ALL handlers' paint_overlay(), not just the active tool's. Pre-Phase-7 the temp paint/eraser masks and polygon-in-progress drew whenever their state field was populated, regardless of current_tool; Phase 7 had silently hidden them on tool switch. Each handler's paint_overlay short-circuits when its state is empty, so the iteration is cheap. Dead duplicate dialog blocks removed: - annotator_window.py: closeEvent had a second "unsaved changes" dialog AFTER check_unsaved_changes had already prompted and committed/discarded. The block was dead in the happy path (masks were already None) and contained a pre-existing bug — event.accept() was called BEFORE the second prompt, so the post-prompt event.ignore() on Cancel had no effect. Removed the whole block. - controllers/image_controller.py: switch_slice had the same dead duplicate block. Removed. Other P2 cleanups: - widgets/tools/rectangle_tool.py: added has_unsaved_state() (returns True while drawing_rectangle is set) and commit() (treats Yes as discard since a mid-drag rectangle has no finishable state). Removed unused QPointF import. Documentation (CLAUDE.md mandates arc42 updates in the same PR): - docs/09_architecture_decisions.md: new ADR-017 covering the ToolHandler pattern, the deliberate state-on-widget non-decision with rationale, the iterate-all-handlers paint_overlay rule, the has_unsaved_state contract, and a pattern guide for adding a new tool. Acknowledges the state-leak architectural smell that will need a follow-up. - docs/05_building_block_view.md: updated package tree to reflect the full post-Phase-1/6/7 layout (core/, widgets/, controllers/, inference/, io/, ui/, dialogs/, widgets/tools/). Rewrote ImageLabel section to describe the dispatcher pattern and list per-tool state fields. Removed stale references to start_painting / start_erasing / image_label.py at root.

Each tool also owned helper methods on the widget +(`start_painting`, `commit_paint_annotation`, `commit_eraser_changes`, +`finish_polygon`, `cancel_current_annotation`, …).

Tools emit through the widget's existing + Phase 6 signals. + +**Decision**: Option 3. Each tool becomes a subclass of `ToolHandler` +in `widgets/tools/`.

Reason: `AnnotationController.finish_rectangle` +and `finish_polygon` (Phase 5a) read `mw.image_label.current_rectangle` +and `mw.image_label.current_annotation` directly. Moving the state +onto the handlers would have required a parallel controller refactor. +Handlers mutate `self.label.X` for those fields; pure-tool state +(e.g. future tool-internal counters) can live on the handler. See +the architectural-smell note below. + +**What stays on `ImageLabel` (intentional non-extraction)**: + +- Navigation (zoom, pan, offset, scaled pixmap) — cross-cutting. +- SAM bbox / points / magic-wand state — activates from any tool via + the magic-wand toggle, cuts across the main tools. +- Polygon edit mode (`editing_polygon`, `handle_editing_click`, + `handle_editing_move`, `draw_editing_polygon`) — modal state + orthogonal to tool selection; sets `current_tool = None` while + active. Promoting this to a handler would tangle the modal flow. +- DINO `temp_annotations` + `accept_temp_annotations` — + cross-cutting; already touched by ADR-015's event filter. +- `draw_tool_size_indicator` — small enough that splitting it across + paint/eraser handlers buys nothing. + +**`paintEvent` overlay pass**.

Reason: pre-Phase-7 the +temp paint mask, temp eraser mask, and polygon-in-progress rendered +whenever their state was populated, regardless of `current_tool`. +Each handler's `paint_overlay` short-circuits when its state is empty, +so the iteration is cheap and the user can switch tools mid-stroke +without losing visual feedback. + +**Consequences**: +- ✅ `image_label.py` shrinks from 1,239 to ~960 LOC. Adding a new + tool now means: create one file in `widgets/tools/`, register it + in `_tools`, wire a button in `annotator_window.py`. No event-method + edits. +- ✅ Each tool can be unit-tested by instantiating the handler with + a stub `label` carrying signals and `_ctx` — no controller fixture + needed. +- ✅ Phase 6's signal contract (ADR-016) is unchanged: handlers emit + via `self.label..emit(...)`. +- ⚠️ **State leak across the widget boundary.** Handlers reach into + `self.label.X` for state. The contract drifts toward "handler is a + namespaced function bag." Mitigation: revisit if/when controllers + are updated to ask the handler (e.g. `polygon_tool.points()`) + instead of reading the widget's field. +- ⚠️ `deactivate()` is no-op by default. If you make it + `discard()` later, audit the three call sites that still write + `current_tool = None` directly (`ImageLabel.clear()`, + `ImageLabel.start_polygon_edit`, three locations in + `SAMController`) — they bypass `set_active_tool` and therefore the + hook. +- ⚠️ `check_unsaved_changes` now iterates all handlers, not just + paint/eraser. Polygon participates via `has_unsaved_state() = len > 2` + (sub-3-point polygons are silently discarded on switch — they + can't be saved anyway). + +**Pattern for adding a new mouse-driven tool**: + +1. Create `widgets/tools/foo_tool.py` with `class FooTool(ToolHandler):`. +2. Override the event hooks you need; emit via + `self.label..emit(...)` and read via `self.label._ctx.X()`. +3. Register in `ImageLabel.__init__`'s `_tools = {…, "foo": FooTool(self)}`. +4. Add a button in `ImageAnnotator.setup_tool_buttons()` and a branch + in the tool-toggle handler that calls + `self.image_label.set_active_tool("foo")`. + +**Related**: +- Implementation: `widgets/tools/base.py`, + `widgets/tools/{rectangle,polygon,paint,eraser}_tool.py`, + `widgets/image_label.py:set_active_tool`, + `widgets/image_label.py:paintEvent` overlay-iteration block. +- Predecessor: ADR-016 (Phase 6 signal decoupling) made this safe by + removing the `main_window` reference; handlers don't need an + orchestrator handle. +- Cross-cuts: documented in + [Cross-cutting Concepts → Canvas Decoupling](08_crosscutting_concepts.md#canvas-decoupling--signals--canvascontext) + (extended to describe the tool dispatcher). + +--- + ## Decisions Under Consideration ### Consider pytest-qt for Utility Testing diff --git a/src/digitalsreeni_image_annotator/annotator_window.py b/src/digitalsreeni_image_annotator/annotator_window.py index 00d88c2..5ddbb10 100644 --- a/src/digitalsreeni_image_annotator/annotator_window.py +++ b/src/digitalsreeni_image_annotator/annotator_window.py @@ -414,33 +414,13 @@ def update_all_images(self, new_image_info): return self.image_controller.update_all_images(new_image_info) def closeEvent(self, event): + # check_unsaved_changes prompts and commits/discards as the + # user chooses; returns False on Cancel. if not self.image_label.check_unsaved_changes(): event.ignore() return event.accept() - if ( - self.image_label.temp_paint_mask is not None - or self.image_label.temp_eraser_mask is not None - ): - reply = QMessageBox.question( - self, - "Unsaved Changes", - "You have unsaved changes.

Also delete three dead UI builders that were never called from anywhere, and factor two inline init blocks (snake-game F2 shortcut, DINO review event filter) into small named functions. After this change, ImageAnnotator.setup_ui() is a short sequence of function calls: build_menu_bar(self) build_sidebar(self) build_image_area(self) build_image_list(self) self.setup_slice_list() self.update_ui_for_current_tool() What changed: - New ui/menu_bar.py (~115 LOC): build_menu_bar(window) — moves create_menu_bar verbatim. Every action.triggered connects to a window. (the existing delegate methods on ImageAnnotator that forward to controllers). - New ui/sidebar.py (~310 LOC): build_sidebar(window) + build_image_area + build_image_list. Widget refs attach as window.X = QWidget(...) so the rest of the code that reads self.class_list etc. keeps working unchanged. Private _section_header helper for the section labels. - New ui/shortcuts.py (~25 LOC): install_shortcuts(window) for F2 → snake game, install_event_filters(window) for the ADR-015 DINO review filter. - annotator_window.py: 1725 → 1169 LOC (-556). Methods removed: create_menu_bar, setup_sidebar, setup_image_area, setup_image_list (all moved), plus three dead methods that were never called from setup_ui or anywhere else (setup_class_list, setup_tool_buttons — the latter referenced a ghost self.load_sam2_button widget that's never created, setup_annotation_list). Inline init cleanup: dropped the duplicate early sam_magic_wand_button + tool_group creation (build_sidebar creates them), dropped the duplicate central_widget + layout early init (setup_ui creates them), dropped the duplicate sam_magic_wand_button.clicked.connect post-setup_ui (build_sidebar wires it), and moved class_list.itemChanged.connect next to the class_list construction inside build_sidebar. QtWidgets import block trimmed from ~22 names down to 10. Pattern: functions, not classes. ImageAnnotator builders run once at construction; a class would add nothing. Follows the existing ui/theme.py shape (functions taking the main window). Invariants preserved: - Construction order: menu bar -> central widget -> sidebar -> image area -> image list -> slice list -> update_ui_for_current_tool. - All widget refs that other modules read (class_list, annotation_list, scroll_area, zoom_slider, image_info_label, tool buttons, DINO widgets, etc.) end up on window.X after the builders return. - ADR-015 event filter still installs on QApplication.instance() via install_event_filters. - F2 shortcut still has ApplicationShortcut context. - Phase 6 signal connections (_connect_image_label_signals) unchanged. All 94 tests pass. App boots; menu bar populated; widget refs verified present. https://claude.ai/code/session_01QxGci8QYbXHtV6BpoBLfAU --- .../annotator_window.py | 569 +----------------- .../ui/menu_bar.py | 123 ++++ .../ui/shortcuts.py | 34 ++ .../ui/sidebar.py | 338 +++++++++++ 4 files changed, 512 insertions(+), 552 deletions(-) create mode 100644 src/digitalsreeni_image_annotator/ui/menu_bar.py create mode 100644 src/digitalsreeni_image_annotator/ui/shortcuts.py create mode 100644 src/digitalsreeni_image_annotator/ui/sidebar.py diff --git a/src/digitalsreeni_image_annotator/annotator_window.py b/src/digitalsreeni_image_annotator/annotator_window.py index 5ddbb10..ee41746 100644 --- a/src/digitalsreeni_image_annotator/annotator_window.py +++ b/src/digitalsreeni_image_annotator/annotator_window.py @@ -1,49 +1,34 @@ import os import warnings + from PyQt6.QtCore import Qt, QTimer -from PyQt6.QtGui import ( - QAction, - QColor, - QFont, - QImage, - QKeySequence, - QPalette, - QPixmap, - QShortcut, -) +from PyQt6.QtGui import QPixmap from PyQt6.QtWidgets import ( - QAbstractItemView, QApplication, - QButtonGroup, - QComboBox, QDialog, QFileDialog, QHBoxLayout, - QLabel, QLineEdit, - QListWidget, QMainWindow, QMenu, QMessageBox, - QProgressBar, - QPushButton, - QScrollArea, - QSlider, QTextEdit, - QVBoxLayout, QWidget, ) from .controllers import io_controller from .controllers.annotation_controller import AnnotationController from .controllers.class_controller import ClassController -from .controllers.dino_controller import DINOController, _DINOReviewEventFilter +from .controllers.dino_controller import DINOController from .controllers.image_controller import ImageController from .controllers.project_controller import ProjectController from .controllers.sam_controller import SAMController from .controllers.yolo_controller import YOLOController from .core import image_utils from .ui import theme +from .ui.menu_bar import build_menu_bar +from .ui.shortcuts import install_event_filters, install_shortcuts +from .ui.sidebar import build_image_area, build_image_list, build_sidebar from .dialogs.annotation_statistics import show_annotation_statistics from .dialogs.coco_json_combiner import show_coco_json_combiner from .dialogs.dino_phrase_editor import ClassThresholdTable, PhraseEditorPanel @@ -78,13 +63,8 @@ def __init__(self): self.setWindowTitle("Image Annotator") self.setGeometry(100, 100, 1400, 800) - self.central_widget = QWidget() - self.setCentralWidget(self.central_widget) - self.layout = QHBoxLayout(self.central_widget) - - self.create_menu_bar() - - # Initialize image_label early + # Initialize image_label early — setup_ui's sidebar/image-area + # builders expect it to exist. self.image_label = ImageLabel() self.image_label.sam_box_active = False @@ -147,15 +127,6 @@ def __init__(self): self.image_label.set_context(CanvasContext(self)) self._connect_image_label_signals() - # Create sam_magic_wand_button - self.sam_magic_wand_button = QPushButton("Magic Wand") - self.sam_magic_wand_button.setCheckable(True) - self.sam_magic_wand_button.setEnabled(False) # Initially disable the button - - # Initialize tool group - self.tool_group = QButtonGroup(self) - self.tool_group.setExclusive(False) - # Font size control self.font_sizes = { "Small": 8, @@ -185,32 +156,13 @@ def __init__(self): # Apply theme and font (this includes stylesheet and font size application) self.apply_theme_and_font() - # Connect sam_magic_wand_button - self.sam_magic_wand_button.clicked.connect(self.toggle_tool) - - self.class_list.itemChanged.connect(self.toggle_class_visibility) - # YOLO Trainer self.yolo_trainer = None self.setup_yolo_menu() - # F2 → Snake game (Easter egg).

Updated to point at ui/sidebar.py:build_sidebar. - ADR-015 "Related" block claimed _DINOReviewEventFilter and its installEventFilter call both live in annotator_window.py. The class actually moved to controllers/dino_controller.py in Phase 4b and the install call moved to ui/shortcuts.py in Phase 8. Updated. - docs/05_building_block_view.md: ui/ directory line listed only "menu_bar, sidebar, theme, stylesheets" — added shortcuts. P2 cleanups: - annotator_window.py: dropped the dead ClassThresholdTable / PhraseEditorPanel import (those widgets now instantiated in ui/sidebar.py; the orchestrator only mentions them in a comment). - Updated stale comment "Also, add the options in create_menu_bar method" — the method moved to ui/menu_bar.build_menu_bar in Phase 8. Comment now points there. - ui/sidebar.py: replaced hardcoded color:#555 on lbl_dino_custom with palette(text) so the colour follows the active stylesheet. Pre-existing CLAUDE.md "no hardcoded colors" violation; fixed while touching the file. - Deleted the duplicate self.showMaximized() call (pre-existing cruft). - Renamed controllers.dino_controller._DINOReviewEventFilter -> DINOReviewEventFilter. The underscore convention says "private to this module"; with Phase 8 the symbol is imported by both the orchestrator (historic, since removed) and ui/shortcuts.py. Two outside importers means the underscore was already a lie. Updated all 4 reference sites + docs. All 94 tests pass.

No code changes; the inventory found __init__.py already exposes the documented public API (ImageAnnotator, ImageLabel, SAMUtils, calculate_area, calculate_bbox), no Phase-1-era top-level shims survive, and docs/06_runtime_view.md already names the post-refactor call paths. What was left was three documents lagging the code. What changed: - CLAUDE.md: project-structure tree now shows the subpackage layout (core/, controllers/, widgets/, widgets/tools/, inference/, io/, ui/, dialogs/). "Key Classes" table grew from 3 rows to 14 — CanvasContext, ToolHandler, all 4 tool subclasses, all 7 controllers, SAMUtils, DINOUtils. Test count corrected from "65 tests" to "94 tests". - docs/05_building_block_view.md: new "Level 3: Controllers" section with a one-line responsibility per controller, mirroring the shape of the existing "Level 3: Export/Import Subsystem" section. Cross-references ADR-013 (SAM re-entrancy), ADR-015 (DINO event filter), ADR-016 (signal decoupling). - docs/12_glossary.md: added entries for CanvasContext, Controller (as a pattern term), ToolHandler, the four tool subclasses, and the ui/ builders (build_menu_bar / build_sidebar / build_image_area / build_image_list). "Key Classes (Code)" table grew from 6 rows to 18 with the same coverage as CLAUDE.md, plus the DINOReviewEventFilter and the dialog-housed YOLOTrainer / DimensionDialog / TrainingThread. - docs/11_risks_and_technical_debt.md: rewrote the "No Automated Tests" entry. Old text claimed zero tests (true pre-refactor); current state is 94 tests with ~15% line coverage. The remaining gap — canvas event flow + inference paths — is named, with a concrete plan that leans on the Phase 7 ToolHandler isolation (each handler can be unit-tested with a stub label). All 94 tests pass. Public API import still resolves: `from src.digitalsreeni_image_annotator import ImageAnnotator, ImageLabel, SAMUtils, calculate_area, calculate_bbox`. End state of the 9-phase refactor: - annotator_window.py: 5,900 -> 1,164 LOC (-80%) - image_label.py: 1,193 -> ~960 LOC, no main_window reference - 7 controllers (project, image, sam, dino, yolo, annotation, class) -

Constructed once in `ImageAnnotator.__init__` and passed via `image_label.set_context(ctx)`. ### Controller Architectural pattern used across `controllers/*`. A controller is a `QObject` subclass holding `self.mw = main_window` that owns a single responsibility cluster carved out of the old monolithic `ImageAnnotator` — project I/O, image loading, annotations, classes, SAM, DINO, or YOLO. The orchestrator delegates to the controllers via thin pass-through methods, keeping external entry points (menu actions, signal connections) stable across refactors. Seven controllers exist as of Phase 8. ### ToolHandler -Base class for per-tool mouse / key / paint behaviour inside `ImageLabel`. Plain Python object (not a `QObject`); holds a back-reference to the widget for signal emission and `CanvasContext` reads.

      1. Select a SAM model from the "Pick a SAM Model" dropdown. It's recommended to use smaller models like SAM2 tiny or SAM2 small for better performance.
      2. Note: When you select a model for the first time, the application needs to download it. This process may take a few seconds to a minute, depending on your internet connection speed. Subsequent uses of the same model will be faster as it will already be cached locally, in your working directory.
