fn get_next( &self, element: &Ref<InputElement>, direction: NavigationDirection, ) -> (bool, Option<Ref<InputElement>>)

Gets the next element in the specified navigation direction.

element is the element being navigated from. Returns a tuple consisting of:

  • a boolean indicating whether the request was handled. If false is returned then custom navigation will be bypassed for the request.
  • if handled is true: the next element in the navigation direction, or None if default navigation should continue outside the element.
