Struct FocusManager 

pub struct FocusManager {
    pub focusable_ids: Vec<String>,
    /* private fields */
}

Manages keyboard focus across interactive components.

Fields

focusable_ids: Vec<String>

Ordered list of focusable component IDs (depth-first traversal order).

Implementations

impl FocusManager

pub fn new() -> Self

Create an empty focus manager.

pub fn rebuild_from_components(&mut self, components: &SurfaceComponentsModel)

Rebuild the focus list by traversing the component tree depth-first.

Call this whenever the component tree changes (e.g. surface update). Components that are present in focusable_ids retain their focus if the focused ID still exists after the rebuild.

pub fn focus_next(&mut self)

Move focus to the next focusable component (Tab).

pub fn focus_prev(&mut self)

Move focus to the previous focusable component (Shift+Tab).

pub fn is_focused(&self, id: &str) -> bool

Returns true if the component with the given ID currently has focus.

pub fn focused_id(&self) -> Option<&str>

Returns the ID of the currently focused component, if any.

pub fn reset(&mut self)

Clear all focus state.

Trait Implementations

impl Default for FocusManager

fn default() -> Self

Returns the “default value” for a type.
