What a semantics node reports beyond its place, its name, its value and its click: the properties few nodes set. A node holds them only when it sets one, so a node without any stays small.

Fields

state_description: Option<String>

What the control says about itself after its name.

on_click_label: Option<String>

What activating the control does, as a verb phrase a reader reads out.

on_long_click: Option<SemanticsLongClick>

What this control does when a screen reader asks for its long press.

on_long_click_label: Option<String>

What the long press does, as a verb phrase a reader reads out.

on_magic_tap: Option<SemanticsMagicTap>

What this control does on VoiceOver’s magic tap.

on_magic_tap_label: Option<String>

What the magic tap does, as a verb phrase a reader reads out.

input_labels: Vec<String>

The short names a person says to Voice Control to reach this control.

language: Option<String>

The language of this control’s text, as a BCP 47 tag.

custom_actions: Vec<SemanticsCustomAction>

The actions a screen reader lists for the control beyond its click.

canvas_children: Vec<CanvasSemanticsNode>

Controls this node drew rather than laid out; their bounds are relative to this node’s own top-left. See CanvasSemanticsNode.

editable_text: bool

Whether this node is a field a person types into.

multiline: bool

Whether an editable field accepts line breaks, independent of its current text.

is_modal: bool

Whether this subtree makes content outside it unavailable to assistive technology.

selectable_group: bool

Whether the selectable controls under this node form one group.

pane_title: Option<String>

The title of the screen or pane this node is the root of.

error: Option<String>

Why the control’s content is wrong, when it is.

password: bool

Whether this field holds a secret, so its text stays unspoken.

text_selection: Option<TextRange>

Where the caret of an editable field sits, or which stretch of its text is picked.

live_region: Option<LiveRegionMode>

How urgently a screen reader reads this node when its text changes. Compose’s SemanticsProperties.LiveRegion.

progress: Option<ProgressBarRangeInfo>

The value this control holds inside a range. Compose’s ProgressBarRangeInfo.

set_progress: Option<SemanticsSetProgress>

What this control does when a screen reader moves its value.

set_text: Option<SemanticsSetText>

What this field does when a screen reader hands it text.

set_selection: Option<SemanticsSetSelection>

What this field does when a screen reader moves its caret or picks a stretch of its text.

expand: Option<SemanticsExpand>

What this control does when a screen reader asks it to open.

collapse: Option<SemanticsExpand>

What this control does when a screen reader asks it to close.

dismiss: Option<SemanticsDismiss>

What this control does when a screen reader asks to send it away.

vertical_scroll: Option<ScrollAxisRange>

How far this container scrolled up and down, when it scrolls.

horizontal_scroll: Option<ScrollAxisRange>

How far this container scrolled left and right, when it scrolls.

scroll_by: Option<SemanticsScrollBy>

What this container does when a screen reader pages it.

scroll_to_index: Option<SemanticsScrollToIndex>

What this list does when a screen reader asks for the row at an index.

collection: Option<CollectionInfo>

How many rows and columns this list holds, when it is a list.
