Found and fixed in a Windows pass of everyday workflows: unsaved documents are now copied in the background (at most every 10 s) and offered back after a crash or forced quit (file.recover); Ctrl+arrow / Ctrl+Backspace / Ctrl+Delete text motion follows Windows and Linux conventions (keymap::text_motion); number-field scrubbing keeps its value; typing in a Tab-focused field works; default linear gradients and their handles behave; Escape closes dialogs without deselecting; clipped panel hints wrap; the unsaved-changes dialog is translated.

//! The control channel's UI-thread side. The app crate accepts JSON lines on a localhost socket
|
||
//! and queues [`ControlRequest`]s; [`drain`] runs them at the start of a frame so replies reflect
|
||
//! the real UI. Methods:
|
||
//!
|
||
//! - `engine.execute {command, params}` — run any command (no dialogs open)
|
||
//! - `engine.commands {}` — every command with its params doc
|
||
//! - `document.inspect {depth?, allPages?}` / `node.get {id, depth?}`
|
||
//! - `ui.inspect {}` — panel/tab/tool state, canvas rect, timings
|
||
//! - `ui.pointer {kind: down|move|up|click|double|hover|drag, x, y (page) | sx, sy (screen), to?, shift?, alt?, cmd?}`
|
||
//! - `ui.key {key, shift?, cmd?, alt?}` — a shortcut as if typed on the canvas
|
||
//! - `ui.type {text}` — type into the text being edited
|
||
//! - `ui.input {events: [{move|down|up: [x, y], button?} | {key, shift?, alt?, cmd?} | {text} | {leave}
|
||
//! | {hold: {alt?, shift?, cmd?}}]}` — raw pointer and key events for the next frame, as if from the
|
||
//! window (panels, popovers); `hold` keeps modifier keys down for the frames that follow (all
|
||
//! false: released)
|
||
//! - `ui.menu.invoke {id}` — a menu item exactly like clicking it (may open a dialog)
|
||
//! - `ui.set {rightTab?, leftTab?, theme?, home?, palette?, focusRegion?, preview?, presentScroll?, …}`
|
||
//! - `ui.screenshot {path}` — PNG of the window (needs a visible window)
|
||
//! - `ui.render {path, scale?, ids?}` — PNG of the document (no UI chrome; works without a window)
|
||
//! - `window.new {path?, index?}` → `{window}` / `window.list {}` / `window.focus {id}` — several
|
||
//! windows (desktop)
|
||
//! - `app.quit {}`
|
||
//!
|
||
//! Any method takes `window` (an id from `window.list`) to run in that window, with its tabs and
|
||
//! panels; without it, requests go to the window last in front.
