@jsvision/ui / FocusHostAware

Interface: FocusHostAware ​

Defined in: ui/src/router/types.ts:98

Example ​

ts
import { Group } from '@jsvision/ui';

class Router extends Group {
  private focus: FocusHost | null = null;
  attachFocusHost(host: FocusHost): void { this.focus = host; }
}

attachFocusHost(host): void
