}

A focusable event region that participates in text input / IME routing.

Fields

layout: LayoutStyle

enabled: bool

text_boundary_mode_override: Option<TextBoundaryMode>

ime_cursor_area: Option<Rect>

Optional IME cursor area in window visual space.

When set, this is forwarded to WindowTextInputSnapshot.ime_cursor_area while the region is focused. This is a data-only escape hatch for editor ecosystems that own the geometry mapping (buffer ↔ rows ↔ caret rect) outside the mechanism layer.

a11y_label: Option<Arc<str>>

Optional accessibility label for this text input region.

a11y_value: Option<Arc<str>>

Optional accessibility value text for this text input region.

When present, selection and composition ranges are interpreted as UTF-8 byte offsets within this value (ADR 0071).

a11y_required: bool

a11y_invalid: Option<SemanticsInvalid>

a11y_text_selection: Option<(u32, u32)>

Optional selection range (anchor, focus) in UTF-8 byte offsets within a11y_value.

a11y_text_composition: Option<(u32, u32)>

Optional IME composition range (start, end) in UTF-8 byte offsets within a11y_value.

ime_surrounding_text: Option<WindowImeSurroundingText>

Best-effort surrounding text excerpt for IME backends that support it.

This SHOULD exclude any active preedit/composing text and SHOULD be limited to WindowImeSurroundingText::MAX_TEXT_BYTES.
