pub struct FocusManager {
    pub chain: Vec<u64>,
    pub focused: Option<u64>,
}

A manager for programmatic focus navigation.

Wraps a &Scheduler and provides methods to move focus. Can also be used standalone with a focus chain and focused element.

Fields

chain: Vec<u64>

The ordered list of focusable element IDs.

focused: Option<u64>

The currently focused element (if any).

Implementations

impl FocusManager

pub fn new(chain: Vec<u64>, focused: Option<u64>) -> Self

pub fn move_focus(&mut self, dir: FocusDirection) -> Option<u64>

Move focus in the given direction. Returns the new focused element ID, or None if no movement is possible.

pub fn move_focus_spatial( &mut self, dir: FocusDirection, hit_regions: &[HitRegion], ) -> Option<u64>

Spatial focus navigation: find the closest focusable element in a given direction using bounding rect geometry.

pub fn move_tab(&mut self, reverse: bool) -> Option<u64>

Tab forward or backward in the focus chain.

pub fn set_requester_target(requester: &FocusRequester, id: u64)

Set target ID on a FocusRequester (called during layout).
