## Class BasicOptionPaneUI.ButtonAreaLayout

- java.lang.Object
- - javax.swing.plaf.basic.BasicOptionPaneUI.ButtonAreaLayout

- All Implemented Interfaces:
    LayoutManager
  Enclosing class:
    BasicOptionPaneUI

      public static class BasicOptionPaneUI.ButtonAreaLayout
      extends Object
      implements LayoutManager

  `ButtonAreaLayout` behaves in a similar manner to `FlowLayout`. It lays out all components from left to right. If `syncAllWidths` is true, the widths of each component will be set to the largest preferred size width. This class should be treated as a "protected" inner class. Instantiate it only within subclasses of `BasicOptionPaneUI`.
