deafdudecomputers PST GUI Architecture — palworld_aio
App lifecycle (main.py)
Entry: run_aio() (main.py:106). Module-level bootstrap (4-75) resolves binary root, patches sys.path (palworld_coord, palsav, palworld_xgp_import, resources, palworld_aio), and if frozen sets multiprocessing exe + mocks stdin/stdout/stderr.
run_aio() has 3 branches:
- CLI/headless (main.py:112-251): if argv[1] is a Level.sav path. Resets constants, backs up, sav_to_gvas_wrapper, builds caches.
-logsgenerates scan logs;-fixruns 7 cleanup fns then wrapper_to_sav. No GUI. - Loading popup test (--test-loading-popup): shows LoadingPopup 5s.
- GUI mode (264-274): init_language('en_US') → QApplication → excepthook→show_error_screen → Fusion style → MainWindow() → center_window → show → app.exec().
MainWindow (ui/main_window.py:220)
QMainWindow, frameless (Qt.FramelessWindowHint), min 1448×800. Custom title-drag (mousePressEvent:747).
__init__ order (221-252): set is_dark_mode/_is_refreshing/user_settings/lang_map → load_exclusions → _load_user_settings (CONFIG_DIR/user.cfg) → _setup_ui → _load_theme (ThemeManager.apply_global) → sidebar.set_active('tools') [DEFAULT TAB] → _setup_menus → _setup_connections → QTimer async update check → StatusBarStream redirects stdout/stderr → setup_logging.
UI composition (_setup_ui:253-314): HeaderWidget (top) + QHBoxLayout body = SidebarWidget (left, 48px) + QSplitter[ QStackedWidget (center, 9 pages) | ResultsWidget (right dashboard, collapsible) ]. QStatusBar hidden (status sink only).
9 stacked pages (index → tab → setup): 0=Tools(ToolsTab), 1=BaseInventory(BaseInventoryTab), 2=PlayerInventory(PlayerInventoryTab), 3=PalEditor(PalEditorTab), 4=Players(inline SearchPanel+bulk), 5=Guilds(inline, 2 SearchPanels in splitter), 6=Bases(inline SearchPanel), 7=Map(MapTab), 8=Exclusions(inline, 3 SearchPanels).
Signal wiring (_setup_connections:554-556): ONLY save_manager.load_finished→_on_load_finished and save_manager.save_finished→_on_save_finished. Everything else is direct calls.
refresh_all() (685-702): reentrancy-guarded (_is_refreshing) fan-out → re-pulls from constants/save_manager into every panel. F5 triggers it (keyPressEvent:2106).
Action flow: menu items → (label, handler) → QAction.triggered → handler → runs work via run_with_loading → refresh_all(). Context menus build ScrollableContextMenu/QMenu with _create_action.
GLOBAL STATE HUB — constants.py (THE central pattern)
constants.py is a module of globals — every manager/tab does from palworld_aio import constants and reads/writes attributes directly. No encapsulation, no classes. This is how data flows between managers.
Loaded save data:
loaded_level_json(50) — THE GvasFileWrapper holding decoded Level.sav. Single mutable source of truth. Its['properties']['worldSaveData']['value'](="wsd") is what everything edits.current_save_path(49) — path to save FOLDER (Level.sav + Players/).original_loaded_level_json(51) — snapshot for comparison/reset.backup_save_path(52).
Guild/player caches:
srcGuildMapping(53) — MappingCacheObject (has .GroupSaveDataMap, .BaseCampMapping, ._worldSaveData).base_guild_lookup(55) — {base_id_str: {GuildName, GuildID}}.player_levels(54),PLAYER_PAL_COUNTS(58),PLAYER_DETAILS_CACHE(59),PLAYER_REMAPS(60),selected_source_player(64).
Container lookups: container_lookup (56) — lazy memoized {container_id_lower: container_dict}. get_container_lookup() (69-84) builds on demand; invalidate_container_lookup() (85-87) resets. The cross-cutting invalidation call — invoked by load, deletes, mutations, bulk ops.
DPS/deletion state: files_to_delete (57, set), exclusions (61, {players/guilds/bases} persisted to EXCLUSIONS_FILE), death_bag_protected_instance_ids (62), death_bag_protected_container_ids (63), dps_executor (65), dps_futures (66), dps_tasks (67).
Static config (4-48): theme colors (BG/GLASS/ACCENT/TEXT/etc), fonts (FONT_FAMILY), URLs (GITHUB_RAW_URL, GIT_REPO_URL, *_VERSION_URL), paths (ICON_PATH, EXCLUSIONS_FILE), path helpers (get_base_path/get_src_path/get_icon_path).
CRITICAL GOTCHA — the reset block is triplicated: on new load, ALL globals reset to defaults. This block is copy-pasted in 3 places: main.py:132-151, save_manager.py:52-71, and inline in reload_current_save. Adding a new global requires editing all three.

Data flow (concrete trace)
Load: _load_save → save_manager.load_save → reset constants → backup → run_with_loading(load_task): sav_to_gvas_wrapper(p) → constants.loaded_level_json → invalidate_container_lookup → scan_and_protect_death_bags → dynamic_manager.sync → _build_player_levels → MappingCacheObject.get → srcGuildMapping → base_guild_lookup → _count_pals_found → PLAYER_PAL_COUNTS+logs → emit load_finished(True) → refresh_all.
Edit: tabs call managers directly. Managers mutate constants.loaded_level_json IN PLACE (by dict reference). Some also write player .sav files independently (PlayerInventory._save_player_sav, player_manager, guild_manager.move_player_to_guild).
Save: _save_changes → save_manager.save_changes → wrapper_to_sav(loaded_level_json, Level.sav) → serializes GvasFileWrapper.gvas_file → compress_gvas_to_sav → writes Level.sav → deletes files_to_delete UIDs → emit save_finished.
KEY INSIGHT — mutable save data lives in TWO places:
constants.loaded_level_json(world/Level.sav data) — mutated in place, flushed to disk only by save_changes.- Per-player .sav files — loaded independently, edited, written back IMMEDIATELY via gvasfile_to_sav (NOT deferred). So "Save Changes" persists only Level.sav; in-flight player edits are already on disk.
Communication patterns
- constants.py globals = PRIMARY. All data flows through module globals, not parameters.
- Direct function calls = most manager invocations. No message bus/service locator.
- Qt signals = MINIMAL — only SaveManager↔MainWindow. UI widgets use signals internally.
- Singletons: BaseInventoryManager.get_instance(), get_dynamic_item_manager(), ItemData(), save_manager module instance.
- Invalidation protocol: invalidate_container_lookup() is the cross-cutting call; BaseInventoryManager.invalidate_cache(); MappingCacheObject._MappingCacheInstances.clear() on load.
Coupling smells: triplicated reset block; DataManager get_bases defined twice (dead code); main_window.py is a 2144-line god-class (~80 handlers); many managers write player .sav independently bypassing save_manager.
