Enum FocusAction

#[non_exhaustive]
pub enum FocusAction {
    Normal,
    Cancel,
    Lock,
}

The actions triggered by a Focusable.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Normal

Acts like a standard navigation node.

Goes into relevant menu if any MenuSetting is reachable from this Focusable.

Cancel

If we receive NavRequest::Action while this Focusable is focused, it will act as a NavRequest::Cancel (leaving submenu to enter the parent one).

Lock

If we receive NavRequest::Action while this Focusable is focused, the navigation system will freeze until NavRequest::Unlock is received, sending a NavEvent::Unlocked.

This is useful to implement widgets with complex controls you don’t want to accidentally unfocus, or suspending the navigation system while in-game.
