Focus(Option<ViewId>)

Manages input focus state for focusable views like InputField.

This event controls which view currently receives keyboard input. It is not a navigation event — use Event::Show to transition between screens or display new UI components.

Variants

• Focus(Some(view_id)) — Grants focus to the view matching view_id. The focused view will receive Event::Keyboard events. Parent views typically use this to show the on-screen keyboard.
• Focus(None) — Clears focus from all views. Parent views typically use this to hide the on-screen keyboard.

Dispatch behavior

Focus events are broadcast: InputField returns false after handling this event so that all input fields in the hierarchy can update their focused/unfocused state.

Sending

Typically sent through the hub (hub.send(...)) by:

• An InputField when tapped while unfocused
• A parent view after building a screen that contains an input field
• A keyboard’s hide method to clear focus

Example

use cadmus_core::view::{Event, ViewId};
use cadmus_core::view::ota::OtaViewId;

// Focus the PR input field (e.g. after building the PR input screen).
// Note: `hub` is provided by the application's event loop.
hub.send(Event::Focus(Some(ViewId::Ota(OtaViewId::PrInput)))).ok();

// Clear focus from all views.
hub.send(Event::Focus(None)).ok();
