By default, SortingFocusTraversalPolicy implicitly transfers focus down-
cycle. That is, during normal focus traversal, the Component
traversed after a focus cycle root will be the focus-cycle-root's default
Component to focus. This behavior can be disabled using the
By default, methods of this class with return a Component only if it is
visible, displayable, enabled, and focusable. Subclasses can modify this
behavior by overriding the accept method.
This policy takes into account focus traversal
policy providers. When searching for first/last/next/previous Component,
if a focus traversal policy provider is encountered, its focus traversal
policy is used to perform the search operation.
