Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: u64

Identity, stable across frames for the same widget.

role: Role

What the node is.

name: Option<String>

The accessible name: a label, or the text inside for roles that take their name from content.

description: Option<String>

Extra description, read after the name.

value: Option<String>

A text value (text fields, combo boxes, sliders with formatted values).

numeric: Option<NumericValue>

A numeric value with its range.

toggled: Option<Toggled>

Checked state.

selected: Option<bool>

Selected state (tabs, options, rows, days).

expanded: Option<bool>

Expanded state of something that opens (menus, combo boxes, disclosures).

disabled: bool

The control does not respond to input.

read_only: bool

The value can be read and selected, but not changed.

focusable: bool

Keyboard focus can be on it.

modal: bool

While it is open, the rest of the app is inert (dialogs).

level: Option<u32>

Heading level, 1 to 6.

active_descendant: Option<u64>

The option highlighted inside a focused text field that drives a list (combobox pattern): screen readers announce it as if it had focus.

bounds: Rect

Absolute frame in logical pixels.

children: Vec<u64>

Child node ids in reading order.

actions: Vec<AccessAction>

Actions assistive technology may request.

Implementations
