The scan/opening/status/error lines, offline mode and its retry, pinning a
collection offline, the sync and thumbnail-sweep state, and the callbacks
that route the grid to a rescan, a sync, another library, a panorama merge
or an export — the last of what AppWindow still carried under the
library- prefix — move onto the `Library` global started earlier on this
branch. Rust reaches them through window.global::<Library>() rather than
window.set_/get_/on_/invoke_ on the root.
library-visible is the one name that stays: it is computed from
active-page and active-view, the shell's own routing state, which a
global cannot read. AppWindow now declares no other library- property or
callback.
The date-range fields and their band on the capture-time axis, the
timeline's bars, labels, scrub/pinch/pan/zoom callbacks and its
sweep/current-bucket/anchored state, and the filter bar's people chips,
mode, eyes-open toggle and gesture reference move from AppWindow onto the
`Library` global. Rust reaches them through window.global::<Library>()
rather than window.set_/get_/on_ on the root, as the earlier commits on
this branch did for the grid's cells, selection, ratings and keywords.
The keywording sheet's rows and its open/assign/unassign callbacks, the
star and flag callbacks a cell click or a judgement key fires, the burst
toggle and representative-chosen callbacks, the trash-selection shortcut,
and the rating/unjudged/flag filter chips with their rating-counts model
move from AppWindow onto the `Library` global started in the previous
commit. Rust reaches them through window.global::<Library>() rather than
window.set_/get_/on_ on the root.
AppWindow carried the grid's loaded window of cells, the keyboard cursor,
drag and drop, the held-row long-press state, columns and cell size, the
scroll and viewport bookkeeping, the photo roll's pick and centre-request,
and the local-only/reorder/collection-filing gestures that act on a
selection, as properties and callbacks on the root component. That state now
lives in the `Library` global declared in library.slint, next to the structs
(LibraryCell, TimelineBar, KeywordRow, PersonChip) it and the grid's other
components already share; Rust reaches it through
window.global::<Library>() instead of window.set_/get_/on_/invoke_ on the
root, the same change collections.slint's `Collections` global made for the
sidebar.
library-visible stays on AppWindow: it is computed from active-page and
active-view, the shell's own routing state, which a global cannot read.
Everything else still prefixed library- — the timeline, the filter bar,
ratings and flags, keywording, and the routes and status lines — stays on
the window for now and moves in the commits that follow.
AppWindow carried the sidebar's tree, its row menu, renaming, drag and
drop between rows, the trash row, and the membership sheet as ~40
properties and callbacks on the root component, in the pattern CH-1
describes and the develop screen's globals (Adjustments, Framing, Steps,
...) already replaced. Collections.* in collections.slint now holds that
state, declared next to the MembershipRow struct it and the membership
sheet both use; Rust reaches it through window.global::<Collections>()
instead of window.set_/get_/on_/invoke_ on the root.
collection-selected, collection-select, and collection-offline-menu stay
on AppWindow: library_ui.rs invokes collection-select directly and
registers collection-offline-menu's handler, and lib.rs reads
collection-selected for back-navigation, so moving them would have meant
editing library_ui.rs, which another change on this branch is splitting
into a module directory. collections-visible stays too — it is
lib.rs's panel-layout state, seeded from the saved layout before the
sidebar exists, and collections_ui never touches it. Everything prefixed
library- (the grid's drag, selection and keyword state that the sidebar's
Rust also wires for cross-feature gestures like filing a selection into
a collection) stays on the window as well, since it belongs to the
library screen, not the sidebar.
collections_ui.rs had grown to 4,591 lines covering the sidebar controller,
the click/drag selection policy, tree refresh, the drag gesture, the trash
worker, twelve wiring functions, and the row's rename/create/context menu,
all in one file. Split into collections_ui/ with one module per area, the
way develop/ and library/ were already split on this branch:
- controller.rs: CollectionsController and the pure drop/delete/release
decisions (decide_drop, decide_delete, decide_release, menu_detail,
delete_warning) that a test can drive without a window.
- press.rs: PressUndo and the click-and-release selection policy
(apply_press, select_row, commit_press, cancel_press).
- tree_sync.rs: rebuilding the sidebar from the catalog and pushing
catalog-derived state into the grid (refresh_tree, offline_state,
sync_lifted/sync_selection/sync_reorderable/sync_badges,
refresh_membership, direct_holdings).
- drag.rs: the cursor bitmap (compose_drag_image, blit_scaled) and the
hold/spring timers (arm_hold, arm_spring, should_spring,
collapse_spring_opened) plus their delay constants.
- trash.rs: the soft delete (start_trash, start_restore, drain_trash,
stop_trash, refresh_trash, format_bytes).
- wiring_grid.rs / wiring_tree.rs: the wire() entry point and its twelve
wire_* functions, split in two because together they were the largest
single piece (grid-facing selection/drag/trash vs. sidebar-facing
navigation/create/rename/row-drag/menu/membership).
- rename_menu.rs: creating, naming and renaming collections, and the row's
context menu (apply_rename, create_child, unique_name, open_row_menu,
close_row_menu, close_rename).
mod.rs carries the module's own top-level doc comment, the `pub use`
re-exports for the eight items the rest of the crate reaches by
`collections_ui::` path (CollectionsController, wire, refresh_tree,
sync_badges, sync_selection, select_row, commit_press, cancel_press), and a
shared `test_support` for the one fixture (`ids`) more than one file's
tests needed. Every item that only crossed a boundary within this module,
not out of it, was narrowed to `pub(super)` rather than kept at the
crate-wide `pub` a single file gave it for free.
Extracted with a brace-aware pass that kept each item's own leading doc
comment and attributes attached to it, and tests moved with the code they
exercise; every TRACES/GESTURE comment lands on the same code it did
before. No file outside the new directory changed — lib.rs's `mod
collections_ui;` resolves to the directory automatically, and every
outside caller's `collections_ui::` path still resolves through mod.rs's
re-exports.
