Struct FocusManager 

pub struct FocusManager { /* private fields */ }

Centralized focus manager.

Call register for each focusable element, then rebuild_order to sort by tabindex before navigating.

Implementations

impl FocusManager

pub fn new() -> Self

Create an empty focus manager with no focused element.

pub fn current(&self) -> Option<FocusId>

The currently focused element, if any.

pub fn is_focus_visible(&self) -> bool

Whether the focus ring should be visible (set by keyboard navigation).

pub fn set_focus_visible(&mut self, visible: bool)

Explicitly set focus-ring visibility.

pub fn set_focus(&mut self, id: FocusId)

Programmatically focus a specific element.

pub fn clear_focus(&mut self)

Clear focus from all elements.

pub fn register(&mut self, id: FocusId, tabindex: i32)

Register a focusable element with a tabindex.

• tabindex >= 0: participates in keyboard navigation.
• tabindex < 0: focusable via set_focus only, skipped by navigate.

If the element is already registered, its tabindex is updated.

pub fn unregister(&mut self, id: FocusId)

Remove a focusable element. If it was focused, focus is cleared.

pub fn rebuild_order(&mut self)

Rebuild the internal navigation order from registered elements.

Must be called after registering or unregistering elements, and before calling navigate.

Ordering rules:

1. Elements with tabindex < 0 are excluded.
2. Elements with tabindex > 0 come first, sorted ascending.
3. Elements with tabindex == 0 follow, in registration (document) order.

pub fn navigate(&mut self, direction: FocusDirection) -> FocusResult

Navigate focus forward or backward.

Automatically enables focus_visible.
