it through. drawing The closed drawing command set a Canvas node carries. elements events message Transient messages: the one sentence an application says after something happened. prelude protocol Fixed-layout little-endian boundary protocol. renderer schema Closed Rust-side schema and metadata used for Kotlin code generation. spans Runs of different treatment inside one Text. tokens Design token tables. window The window’s measured size, and the hook components read it through. android_main Declares the Android entry point for an application’s cdylib. ios_main Declares the entry point an iOS application starts at. rsx The rsx! macro makes it easy for developers to write jsx-style markup in their components. web_main Declares the browser entry point for an application’s wasm module. FileDrop The paths of the files a reader let go over a node. KeyEvent A key-down event whose consumption state is shared with the Host boundary. RangeRequest The visible item range the Renderer asks the Host to materialise. VirtualDom A virtual node system that progresses user events and diffs UI trees. Badge A small mark on something else that says how many, that there is something new, or one
short word. Box Props Button The variant is the seam the design system’s component rule attaches to.
The same rsx draws differently per system, and that is correct behaviour. Canvas Pixels the widget vocabulary cannot produce: charts, sparklines, signature pads, rings. Card A grouped container. What a card looks like, its background, corner and resting
elevation, is the design system’s decision, so the widget carries no appearance of its
own. Modifier::Elevation overrides the resting height when the Host has a reason to. Checkbox A two-state box. Column Props DatePicker A date, as whole days since 1970-01-01. Dialog A modal. open seeds the Renderer’s own open state and carries changes that came from
somewhere other than the Renderer; the Renderer runs the enter and exit itself so the
animation never round trips through the Host. on_dismiss fires when the user asks to
close it, and the Host decides whether to honour that by setting open to false. Divider A line between two things. The axis is the only decision the Host makes: the
thickness, the colour and the inset all come from the design system. Dropdown One choice out of a list. Each child is one option, and the Renderer reports the
position the user landed on. FileDropTarget A place files may be dropped. Icon A registered icon, tinted by a role. Host::register_icon registers the meaning rather
than a picture, so the same declaration comes out as the icon each design system draws. Image A registered asset drawn as a picture. The bytes reached the Renderer once, through
Host::register_asset, and what crosses per frame is the id. LazyColumn A windowed list. The Host declares item_count and a stable key per item, and
materialises exactly the range the Renderer last requested. LazyGrid A grid that only builds the rows it can show. LazyRow The horizontal axis of the same windowing protocol LazyColumn uses, with the same
contract: the Host materialises exactly the range the Renderer last asked for, and the
read-ahead buffer belongs to the Renderer because the scroll position does. LinearProgressIndicator Material 3’s determinate linear progress indicator, as a worked extension example. Menu A popup anchored to anchor, which is the widget the menu hangs off. The anchor is the
first child on the wire and the entries follow it, so the Renderer can place the popup
without the Host knowing any screen coordinates. Navigation A set of destinations with one of them selected, plus the screen they lead to. NavigationItem One destination inside a Navigation ProgressIndicator Work in progress. determinate says whether value means anything, and circular
picks between the two forms every supported design system has. RadioButton One choice out of several. Which siblings it excludes is the Host’s business, so the
widget carries only whether this one is the chosen one. Row Props Scaffold The screen’s frame: a top bar, a bottom bar, a floating action and the page. ScrollColumn The whole content with a vertical scroll attached. The scroll position is the
Renderer’s, like focus and animation state, so scrolling never reaches the Host. SelectionContainer A region whose text can be dragged over and copied as one selection. Separator A hairline between two rows of a grouped list. Sheet A temporary surface that slides in from an edge, holding whatever its children are. Slider A value picked from a range. Spacer Props Surface A plain background-and-elevation container. Use it where a Card’s grouping meaning
would be wrong and only the surface is wanted. Switch An on/off control. The same contract as Checkbox: the Host owns the value, and the
track, the thumb and the way the change is animated belong to the design system. Tabs A row of tabs. Each child is one tab. Text type_role alone takes the design system’s size, weight, line height and letter
spacing. Each override replaces one axis and costs one SetProp, so changing the font
size does not resend the rest of the text’s styling.TextField Props TimePicker A time of day, as minutes since midnight. Tooltip An explanation attached to its child. It is a description as much as a hover popup: the
Renderer also exposes the text to the accessibility tree, so a pointer is not the only
way to reach it. TopAppBar The bar across the top of a screen. Its children are its content, left to right. How the
bar is sized, spaced and separated from what is below it is the design system’s rule. Element An ElementVNoderender on ScopeIdScopeState component Component Props Props
