The possible accessible relations of a Accessible.

Accessible relations can be references to other widgets, integers or strings.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ActiveDescendant

Identifies the currently active element when focus is on a composite widget, combobox, textbox, group, or application. Value type: reference

ColCount

Defines the total number of columns in a table, grid, or treegrid. Value type: integer

ColIndex

Defines an element’s column index or position with respect to the total number of columns within a table, grid, or treegrid. Value type: integer

ColIndexText

Defines a human readable text alternative of ColIndex. Value type: string

ColSpan

Defines the number of columns spanned by a cell or gridcell within a table, grid, or treegrid. Value type: integer

Controls

Identifies the element (or elements) whose contents or presence are controlled by the current element. Value type: reference

DescribedBy

Identifies the element (or elements) that describes the object. Value type: reference

Details

Identifies the element (or elements) that provide additional information related to the object. Value type: reference

ErrorMessage

Identifies the element that provides an error message for an object. Value type: reference

FlowTo

Identifies the next element (or elements) in an alternate reading order of content which, at the user’s discretion, allows assistive technology to override the general default of reading in document source order. Value type: reference

LabelledBy

Identifies the element (or elements) that labels the current element. Value type: reference

Owns

Identifies an element (or elements) in order to define a visual, functional, or contextual parent/child relationship between elements where the widget hierarchy cannot be used to represent the relationship. Value type: reference

PosInSet

Defines an element’s number or position in the current set of listitems or treeitems. Value type: integer

RowCount

Defines the total number of rows in a table, grid, or treegrid. Value type: integer

RowIndex

Defines an element’s row index or position with respect to the total number of rows within a table, grid, or treegrid. Value type: integer

RowIndexText

Defines a human readable text alternative of aria-rowindex. Value type: string

RowSpan

Defines the number of rows spanned by a cell or gridcell within a table, grid, or treegrid. Value type: integer

SetSize

Defines the number of items in the current set of listitems or treeitems. Value type: integer

Implementations

impl AccessibleRelation

pub fn init_value(self, value: &mut Value)

Trait Implementations

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

Formats the value using the given formatter.

impl Display for AccessibleRelation

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

Formats the value using the given formatter.

impl From<AccessibleRelation> for Value

fn from(v: AccessibleRelation) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for AccessibleRelation

type Checker = GenericValueTypeChecker<AccessibleRelation>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for AccessibleRelation

type ParamSpec = ParamSpecEnum

type SetValue = AccessibleRelation

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: AccessibleRelation) -> ParamSpecEnumBuilder<'_, AccessibleRelation>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for AccessibleRelation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AccessibleRelation

fn cmp(&self, other: &AccessibleRelation) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
