Struct FocusRequester 

pub struct FocusRequester { /* private fields */ }

A handle an app holds to move focus onto a node imperatively.

remember one, hang it on a node with Modifier::focus_requester next to a Modifier::focus_target (or Modifier::on_focus_changed), and call request_focus — from a click handler, an effect that runs once a screen appears, wherever the app decides focus should move.

let requester = remember(FocusRequester::new).with(Clone::clone);
// ... in the composition:
Modifier::empty().focus_requester(&requester).focus_target()
// ... later, imperatively:
requester.request_focus().ok();

Implementations

pub fn request_focus(&self) -> Result<(), FocusRequestError>

See FocusRequestError for the two predictable ways this can fail instead of moving focus.

pub fn node_id(&self) -> Option<NodeId>

The node this requester is attached to, if attached.
