widgets, input: PatternGrid for pattern unlock, framed icon buttons, and text keys that bubble past a focused non-text widget; Debian 0.3.0-2
PatternGrid is a 3×3 drag widget for the unlock pattern. It is stateless: the app owns the visited nodes and passes them back in for drawing; a press or a drag that reaches a node within the snap radius fires on_node with the index, 0 to 8 row-major, and release fires on_release, so the crossing and minimum-length rules stay in the app. Geometry lives in widget/pattern_grid/theme.rs (size, dot and node radii, stroke width, snap radius, ring alpha), and the snap radius is resolved through the widget-scaling mode at layout time like the slider thumb (set_pattern_snap_px). The gesture machine reuses the slider's drag ownership: WidgetHandlers::is_drag_target covers both, so hover painting, pointer capture and release behave the same, and hover_affects_paint no longer special-cases sliders. The a11y tree maps it to GenericContainer, since a drawn gesture has no assistive equivalent and the app must offer another method. Exported as pattern_grid / PatternGrid, documented in widgets.md, theming.md and architecture.md, with tests for node centres, a wide rect, snapping, the builders, the handler snapshot and map_msg, and a Security tab in examples/widgets.rs that shows the drawn path. Icon buttons given a width or height are framed keys: preferred_size honours the explicit size instead of the icon size, and drawing paints the variant's background, border and focus ring, shared with text buttons through paint_frame, then centres the icon. An icon button without a size keeps the circular hover overlay it had. This is what lets the PIN keypad's backspace and OK keys sit in the same circles as the digits. Keyboard routing now matches what App::on_key documents. handle_key_default, Backspace, Delete and Space checked focused_idx.is_some() and sent the key into text insertion whenever any widget had focus, which is a no-op on a button, so a focused button or pressable swallowed typed characters. focused_text_input replaces the five copies of that check; characters, Backspace and Delete stay in a focused text input and reach the app otherwise, Return and Space still go to the focused widget's submit or press message when it has one, and the arrow, Home and End handlers use the same helper. The lockscreen relies on this to take PIN digits with its dots row focused. debian/changelog: 0.3.0-2. |

Session management: xdg-session-management-v1 client, mandatory App::app_id / save_state / restore_state, runtime-managed state persistence and clean exit on signals (0.3.0)
Applications built on ltk had no way to come back where the user left them: the toolkit hardcoded `app_id = "ltk"` on every toplevel, never wrote anything to disk, and died on SIGTERM without a chance to save. This release gives the runtime the whole plumbing and asks each application only for the bytes worth keeping, in the spirit of Android's saved-instance state. The `App` trait gains three mandatory methods, deliberately without default bodies so every application states its position: `app_id()` (reverse-DNS, used for `xdg_toplevel.set_app_id`, the AccessKit application name and the state directory — the `app_id` element of the deprecated `window_config` tuple is now ignored and a one-time warning reports a mismatch), `save_state() -> Option<Vec<u8>>` and `restore_state(Vec<u8>)`. The bytes are opaque; the trait carries no serde bound. Their rustdoc is the contract: when the runtime saves, where the files live, when the bytes come back and when they do not, what must never go in them, and a worked serde_json example. The runtime persists under `$XDG_STATE_HOME/<app_id>/` (falling back to `~/.local/state`): `session.json` holds the compositor session id, a clean-exit marker and the writer's pid; `state.bin` holds the application bytes. Writes are atomic (temp file + rename, mode 0600, directory 0700) and best-effort. State is saved every 30 s when the bytes changed, once after the event loop exits (which covers `on_close_requested`, `requested_exit` and lost connections), and on SIGTERM/SIGINT — a calloop signal source, installed before any thread exists, now turns those into a clean exit of the loop instead of process death. `restore_state` runs synchronously in `try_run` before the window is created and before the first `view()`, and only when the process is relaunched as part of a session restore (`LTK_SESSION_RESTORE=1`, removed from the environment before the app can spawn children) or when the previous run left `clean_exit: false`; a plain launch starts fresh. A second concurrent instance detects the live pid and runs with persistence disabled rather than clobbering the first. The compositor side of geometry restore goes through `xdg-session-management-v1`. Neither wayland-protocols nor sctk ship generated code for it yet, so the XML is vendored under `protocols/` and `wayland-scanner` generates the client module in-tree (`src/protocol/`), resolving the crate names through sctk's reexports so the bindings stay on the crate instances sctk links. Before the first commit of a `ShellMode::Window` toplevel the runtime binds `xdg_session_manager_v1`, calls `get_session(reason, stored_id)` and `restore_toplevel(toplevel, "main")`; the three window-creation paths in `run.rs` are folded into one `make_window` helper so the attach always sits immediately before `commit()`. `created` persists the id, `replaced` destroys the objects and stops persisting. Compositors without the global lose only the geometry half. Layer-shell and session-lock surfaces skip the whole machinery. Every `App` implementor in the tree is updated: the twelve examples (`showcase`, `scroll` and `mini_shell` persist real state; the rest return `None`), both integration tests (`event_loop_flow` gains `save_restore_round_trip`), the in-source and markdown doctests, README, onboarding, cookbook (new recipe "Surviving relaunch: session state") and architecture docs, and the changelog. `src/session_state.rs` carries unit tests over a temporary state directory. `Makefile install` now copies `protocols/` into the cargo registry — without it downstream builds would fail inside the proc-macro — and `debian/copyright` covers the vendored XML. The trait change is breaking, hence 0.3.0. Also fixes the pre-existing `viewport_tests` module in `render/mod.rs`, which used `Length` without importing it and broke `cargo test`. |

layout: adaptive grid and vertical flex; enforce the mechanical style rules
grid_min_cell( width ) adds the adaptive mode WrapGrid was missing: instead of a fixed column count, the count is derived at layout time from the available width so every cell is at least `width` wide (any Length, so a fluid threshold works; never fewer than one column), re-derived on every resize. Cells then share the width equally, and WrapGrid::max_columns( n ) caps the derived count so cells grow instead of multiplying on very wide surfaces — the cap only applies to the adaptive mode, grid( n ) keeps the fixed behaviour untouched. Four new layout tests cover width derivation, spacing accounting, the one-column floor and the cap; the row-wrap assertions check X positions rather than Y because zero-height spacer children produce zero-height rows. flex( child ) now distributes leftover height inside a Column, mirroring its leftover-width behaviour in a Row: flex children join the weight pool alongside weight-only spacers and y-scrolls, draw their child inside the allocated share at full inner width, and contribute zero to the column's natural height exactly like a row counts flex width. This closes the documented "vertical flex is not yet implemented" gap; the Flex rustdoc and the widgets.md entry now describe both axes. Add scripts/style-check.sh and a make stylecheck target, wired into CI: mechanical verification of the grep-checkable subset of code_style_guide.md — tab indentation and spaces inside attribute brackets — with comment lines skipped so prose may cite raw attribute syntax. To turn the check on green, the 82 unspaced attribute sites across 24 files (#[test], #[derive(...)], #[cfg(...)], #[allow(...)]) were normalized to the spaced form. CONTRIBUTING and the style guide reference the new target; brace placement and paren spacing remain review concerns. |

docs overhaul, orientation API, fluid-sizing fixes, examples made honest
Documentation pass: every claim in docs/ and the meta files was audited against the source and the drift fixed — around ninety corrections. CONTRIBUTING and the CI workflow now run cargo test with --features test-support (the gated test_support module made both the documented commands and the CI build fail to compile), make example becomes make examples, make doctest-md and the debhelper requirement of make clean are documented, and patch shape asks for a CHANGELOG entry. theming.md loses the nonexistent surface.backdrop, gains the real gradient defaults (linear-rgb, oklab), the six slot variants including typography, the ten-field palette, a truthful effects-consumer table, the ThemePreference/from_hour API and a responsive-sizing note; the stale docstrings in src/theme that fed the drift are fixed too. architecture.md's "Known gaps" section is rewritten against reality (multi-touch slots, xdg-activation, a11y live regions and SetValue/Increment/Decrement are implemented), gains a module map, subsurfaces and window-lifecycle coverage, and correct crustace/loginmanager paths. widgets.md fixes the ten factual errors (stateless spinner, toast/combo via overlays(), tooltip hover contract, row has no max_width, scroll axes, multiline text_edit, dialog panic wording) and now states the column() 16 px default padding — the recurring ambush — plus row's differing 0 default and dialog's max_width. onboarding, README and cookbook get the remaining sweep: build/test instructions, complete example lists, img_widget, clipping-parity honesty, ~30 Hz software cap, read_rgba_pixels signature, tab indentation in snippets, and rustdoc-style links that rendered literally are gone everywhere. CHANGELOG is restructured per Keep a Changelog with the missing entries (window_resizable, claims_raw_touch, Row::align_top/fill_height, caret fixes, dependency pins) and the pad_v Added/Changed contradiction resolved. New adaptive-layout API: ltk::orientation() with the Orientation enum, backed by viewport_size()/set_viewport_size — the runtime records the main surface's physical dimensions on every configure, before App::on_resize, so view() can branch a layout on portrait vs landscape without hand-tracking resizes. The portrait rule matches Length::orient (square counts as portrait); embedders driving core::UiSurface call set_viewport_size themselves. Documented in the crate root's responsive-design section and architecture.md. Fluid-vs-fixed sizing fixes in widgets, all the same disease — fluid content inside a fixed-pixel box. TextEdit::fixed_width takes impl Into<Length> (f32 call sites keep compiling as px) and the time picker's digit fields move to Length::fluid( 72.0 ), matching their fluid font so digits can no longer outgrow the box. Dialog::max_width takes impl Into<Length> with a Length::fluid( 480.0 ) default so the card scales with the stock buttons inside it, and the card's interior no longer stacks the column() default 16 px padding on top of CARD_PADDING — that double inset squeezed the action row until its buttons clipped on narrow windows. App::on_pointer_axis now triggers a view rebuild and repaint; previously state mutated in the hook did not paint until the next unrelated event. Examples reworked to be honest demos: responsive's mode/density controls become stock buttons in a grid/column so they follow the modes they demonstrate instead of overflowing; dialog's openers stack vertically, and the example gains the app-level ESC handler so the ESC chain closes an open dialog first and quits second; widgets' tab strip now switches real per-tab pages; carousel gains pointer/touch drag through the horizontal-swipe hooks (crustace's pager pattern), one-tile-per-detent mouse wheel, and snap math driven by the real surface width from on_resize instead of a hardcoded 800; clip_path arranges its cells by ltk::orientation() and sizes them from the counter-axis of the flow. |
