Struct FocusScopeNode 

pub struct FocusScopeNode { /* private fields */ }

Persistent focus scope handle.

Scopes own restore behavior and provide imperative traversal within a subtree.

Examples

use tessera_ui::FocusScopeNode;

let first = FocusScopeNode::new();
let second = FocusScopeNode::new();
assert_ne!(first, second);

Implementations

impl FocusScopeNode

pub fn new() -> Self

Creates a new persistent focus scope handle.

pub fn request_focus(&self)

Requests focus within this scope, restoring the last focused descendant when possible.

pub fn clear_focus(&self)

Clears focus from this scope.

pub fn restore_focus(&self)

Restores focus to the last focused descendant of this scope.

pub fn move_focus(&self, direction: FocusDirection) -> bool

Moves focus to another focusable descendant inside this scope.

pub fn cycle_focus(&self, direction: FocusDirection) -> bool

Cycles focus inside this scope, wrapping when traversal reaches an end.

pub fn state(&self) -> FocusState

Returns the current focus state for this scope.

pub fn has_focus(&self) -> bool

Returns true when this scope participates in the active focus path.

pub fn is_focused(&self) -> bool

Returns true when this scope itself is the primary focused node.

Trait Implementations

impl Clone for FocusScopeNode

fn clone(&self) -> FocusScopeNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FocusScopeNode

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

Formats the value using the given formatter.

impl Default for FocusScopeNode

fn default() -> Self

Returns the “default value” for a type.

impl Hash for FocusScopeNode

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 PartialEq for FocusScopeNode

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
