Struct FocusManager 

pub struct FocusManager;

Owner-scoped focus manager for traversal and forced clear operations.

Use the focus manager to trigger application-level traversal without storing a specific scope or requester.

Implementations

impl FocusManager

pub fn current() -> Self

Returns the focus manager for the current component tree.

pub fn save_focus(self) -> Option<FocusRestorationTarget>

Saves the current target for restoring focus after temporary UI closes.

Saving does not move focus or keep the target alive. Restore only while the temporary UI still owns focus, so later user navigation is preserved.

pub fn focus_change_direction(self) -> Option<FocusDirection>

Returns the traversal direction responsible for the focus callback currently running. Explicit focus requests, restoration, and calls outside a focus callback return None.

pub fn defer_keyboard_until_layout(self)

Defers queued keys until the next layout and its focus updates finish.

Use when opening or closing focusable content so subsequent keys reach the resulting focus target.

pub fn clear_focus(self, force: bool)

Clears the current focus. Set force to true to break captured focus.

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

Moves focus in the requested direction.

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

Queues traversal after the next layout, revealing lazy content as needed.

Later requests replace an earlier queued direction. Returns false when the window is unfocused or focus is captured. Following keyboard input waits for the requested traversal and its layout updates. Explicit focus requests, focus capture, and window blur cancel it.
