Interface Focusable.FocusJs

All Superinterfaces:
Serializable
Enclosing interface:
Focusable<T extends Component>
@JsDefinition public static interface Focusable.FocusJs extends Serializable
The client-side operations behind Focusable, as a JavaScript definition for Element.executeJs(Class).

Focus and blur are marked as server-initiated for the client, so that the resulting event reports isFromClient() == false. A driver of the client side that implements this interface instead of running the scripts is responsible for the same.
