Semantics configuration for accessibility.

Fields

content_description: Option<String>

state_description: Option<String>

Compose’s stateDescription.

on_click_label: Option<String>

Compose’s onClick(label = …); implies clickable.

role: Option<SemanticsWidgetRole>

Compose’s Role.

selected: Option<bool>

toggled: Option<bool>

enabled: bool

is_clickable: bool

is_editable_text: bool

text_selection: Option<TextRange>

custom_actions: Vec<SemanticsCustomAction>

canvas_children: Vec<CanvasSemanticsNode>

Controls this node drew itself instead of laying out. See CanvasSemanticsNode.

is_modal: bool

Whether this node takes over the screen: everything outside it is inert, and a screen reader keeps its traversal inside.

live_region: Option<LiveRegionMode>

Compose’s liveRegion. When set, a screen reader reads this node again whenever its text changes, without the user moving to it.

progress: Option<ProgressBarRangeInfo>

Compose’s progressBarRangeInfo. A control with it is adjustable: a screen reader offers its own way to move the value.

set_progress: Option<SemanticsSetProgress>

What the control does when a screen reader moves its value. Compose’s setProgress.

vertical_scroll: Option<ScrollAxisRange>

How far this container scrolled up and down. Compose’s verticalScrollAxisRange.

horizontal_scroll: Option<ScrollAxisRange>

How far this container scrolled left and right. Compose’s horizontalScrollAxisRange.

scroll_by: Option<SemanticsScrollBy>

What this container does when a screen reader pages it. Compose’s scrollBy.

Implementations

impl SemanticsConfiguration

pub fn merge(&mut self, other: &SemanticsConfiguration)

pub fn is_activatable(&self) -> bool

Whether a screen reader should offer activation. A named click label is how Compose declares onClick, so it implies the action the same way.

Trait Implementations

impl Clone for SemanticsConfiguration

fn clone(&self) -> SemanticsConfiguration

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SemanticsConfiguration

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for SemanticsConfiguration

fn default() -> SemanticsConfiguration

Returns the “default value” for a type.

impl PartialEq for SemanticsConfiguration

fn eq(&self, other: &SemanticsConfiguration) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
