  35  * A layout manager that allows multiple components to be laid out either
  36  * vertically or horizontally. The components will not wrap so, for
  37  * example, a vertical arrangement of components will stay vertically
  38  * arranged when the frame is resized.

  49  * Nesting multiple panels with different combinations of horizontal and
  50  * vertical gives an effect similar to GridBagLayout, without the
  51  * complexity. The diagram shows two panels arranged horizontally, each
  52  * of which contains 3 components arranged vertically.
  53  *
  54  * <p> The BoxLayout manager is constructed with an axis parameter that
  55  * specifies the type of layout that will be done. There are four choices:
  56  *
  57  * <blockquote><b>{@code X_AXIS}</b> - Components are laid out horizontally
  58  * from left to right.</blockquote>
  59  *
  60  * <blockquote><b>{@code Y_AXIS}</b> - Components are laid out vertically
  61  * from top to bottom.</blockquote>
