FocusTrigger

public final class FocusTrigger

A trigger for focus and blur actions.

This type is meant to be used in conjunction with FocusState; you will usually not create it directly. For information about adding focus support to a custom element, see FocusBinding.

Triggers allow imperative actions to be invoked on backing views, by creating a trigger in a declarative model before the view is realized, late-binding the actions to a backing view after that view has been realized, and then invoking the action on the trigger later in response to some other event.
