# toddy-iced
Vendored fork of [iced](https://github.com/iced-rs/iced) maintained
for the [Toddy UI](https://github.com/toddy-ui) project. Tracks
iced's master branch with additional features. Version numbers are
independent of upstream iced releases.
## What's different from upstream iced
### Accessibility
- Full accessibility tree via [AccessKit](https://accesskit.dev)
(Linux AT-SPI2, Windows UI Automation, macOS NSAccessibility)
- Accessible properties on all built-in widgets: role, label,
description, value, live regions, orientation, relationships
(labelled-by, described-by), and more
- Alt text support for Image and SVG widgets
- RadioGroup widget with proper radio group semantics
(single Tab stop, arrow key navigation, active descendant tracking)
- Form validation, modal, busy, hidden, and read-only properties
- Alt-key mnemonics mapped to AccessKit keyboard shortcuts
### Keyboard navigation
- Tab/Shift+Tab focus cycling across all interactive widgets
- Ctrl+Tab unconditional focus escape from any widget
- Focus-visible pattern (focus ring on keyboard navigation only,
not on mouse clicks)
- Keyboard activation: Button (Space/Enter), Checkbox (Space),
Radio (Space), Toggler (Space), Slider (arrows, Home/End,
Page Up/Down), PickList (arrows, Enter/Space, Escape), ComboBox
(arrow navigation with Escape state preservation, Tab autocomplete,
Enter/Tab select from dropdown)
- Keyboard scrolling: Page Up/Down, arrows, Home/End; Shift swaps
to horizontal axis
- Scroll-into-view on Tab navigation with nested scrollable cascade
(properly handles backward scrolling and scrollbar overlap)
- Scroll bubbling through ancestor scrollables with tree-wide
directional fallback
- PaneGrid keyboard pane switching (F6/Shift+F6)
- Modal dialog focus trapping via scoped focus operations
- Alt-key mnemonic activation with synthetic click injection
- Escape-to-unfocus with layered dismissal (widget first, then
container)
### Framework APIs
- `runtime::keyboard` module with backend-agnostic keyboard
handlers for custom event loops
- Scoped focus operations (`focus_next_within`, `focus_previous_within`)
for modal and dialog patterns
- Mnemonic lookup operation for Alt+letter widget activation
- Accessibility selectors in `iced_test` for headless a11y testing
- `focus_color`, `focus_border_color`, `focus_shadow`,
`focus_shadow_subtle` palette helpers for consistent focus indicators
- TextEditor undo/redo (Ctrl+Z/Ctrl+Y, Cmd on macOS)
- TextInput/TextEditor `input_purpose` for IME hints
- Markdown `code_theme` for syntax highlighting themes
- `find_focused` runtime operation
- Runtime font loading at any time (not just startup)
### Removed from upstream
- **macOS URL scheme handling** (`event::listen_url`,
`ReceivedUrl` subscription event). Upstream iced uses a forked
winit to support macOS deep links / custom URL schemes. This fork
switches to upstream winit from crates.io, which doesn't include
that feature. We'd like to support it once upstream winit does.
### Crate naming
All crates are published under a `toddy-iced-` prefix. Cargo's
`package` aliasing means Rust source code still uses `use iced::*`
-- the renaming is entirely in Cargo.toml.
