The fragment can get the component of the UI of the parent screen by ID.
For example, such a code a fragment::

@Subscribe(target = Target.PARENT_CONTROLLER)
    public void onAfterShow(Screen.AfterShowEvent event) {

Component fromParent = event.getSource().getWindow().getOwnComponent("scrollBox");
...
}
