"Duplicate originals" appears under the trash in the collections sidebar while the catalog holds any, and Settings says how many there are beside the other whole-library passes. Both open one page: every group with its picture and paths, the copy that stays (tap another path to change it), a per-group Include box, what the survivor will gain and any flag, label or face conflict, and why a group was skipped. The summary is the dry run -- "N groups, M files to trash, K skipped" -- and nothing moves until "Check" has read the copies and "Move M copies to trash" is pressed. Both run on workers with progress on the page, in the activity register and, for the move, on the library status line; Stop ends a job between groups. When it ends the grid, the sidebar and the trash are refreshed and the survivors' judgements are written to their sidecars and XMP the way a rating keystroke writes them. The page is paginated at 30 groups, so a redraw decodes 30 thumbnails and previews 30 merges whatever the size of the library. Back and Escape leave it like its own Back button.

//! TRACES: FR-CAT-7 | FR-UI-5 | NFR-P9
|
|
//! The collections sidebar, grid selection, and the drag between them.
|
|
//!
|
|
//! `dr_catalog::collections` owns the data rules — hierarchy, membership,
|
|
//! revisions, cycles. This module owns the *interaction*: what is selected,
|
|
//! what a drag is carrying, and where a release lands.
|
|
//!
|
|
//! # What this module does and does not own
|
|
//!
|
|
//! Slint's `DragArea`/`DropArea` own the *gesture* — pointer capture, the
|
|
//! threshold separating a click from a drag, arbitration against the grid's
|
|
//! Flickable, the image under the cursor, and hit-testing the release. So the
|
|
//! drop arrives already addressed to a collection, and nothing here tracks
|
|
//! pointer positions or guesses a target.
|
|
//!
|
|
//! What is left here is what Slint cannot know:
|
|
//!
|
|
//! - **the payload** — which images the drag carries, built from the selection
|
|
//! at the moment the drag starts;
|
|
//! - **the spring** — a dwell timer that opens a collapsed collection so a
|
|
//! nested child can be reached mid-drag, and closes again what the drag only
|
|
//! passed over.
|
|
//!
|
|
//! An earlier version hand-rolled the whole gesture on `TouchArea` and did not
|
|
//! work, for a reason worth keeping: an interactive `Flickable` claims any drag
|
|
//! starting inside it for scrolling and cancels the child TouchArea's press, so
|
|
//! the drag could never leave the grid.
|
|
//!
|
|
//! # Selection
|
|
//!
|
|
//! Selection is by **catalog image id**, never by row index. The grid is a
|
|
//! window over the catalog (FR-CAT-4) and scrubbing replaces every row, so an
|
|
//! index-based selection would silently come to mean forty different
|
|
//! photographs after a scrub. Ids survive that; they also survive a rescan.
|
|
//!
|
|
//! # Split into one module per area (docs/dev/code-health.md CH-1)
|
|
//!
|
|
//! `controller` holds the running state and the pure drop/delete/release
|
|
//! decisions; `press` the click-and-release selection policy; `tree_sync`
|
|
//! rebuilding the sidebar and pushing catalog state into the grid; `drag` the
|
|
//! cursor bitmap and the spring; `trash` the soft delete; `wiring_grid` and
|
|
//! `wiring_tree` the callbacks, split in two because together they were the
|
|
//! largest single piece; and `rename_menu` creating, naming and the row's
|
|
//! context menu. `mod.rs` re-exports what the rest of the crate calls by
|
|
//! `collections_ui::` path, so nothing outside this module needs to change.
