## javax.swing.plaf.basic
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 inner class is marked "public" due to a compiler bug. This class should be treated as a "protected" inner class. Instantiate it only within subclasses of BasicOptionPaneUI.

Field Summary
`protected boolean` | `centersChildren` If true, children are lumped together in parent.
`protected int` | `padding`
`protected boolean` | `syncAllWidths`

Constructor Summary
`BasicOptionPaneUI.ButtonAreaLayout(boolean syncAllWidths, int padding)`

Method Summary
`void` | `addLayoutComponent(String string, Component comp)` If the layout manager uses a per-component string, adds the component `comp` to the layout, associating it with the string specified by `name`.
`boolean` | `getCentersChildren()`
`int` | `getPadding()`
`boolean` | `getSyncAllWidths()`
`void` | `layoutContainer(Container container)` Lays out the specified container.
`Dimension` | `minimumLayoutSize(Container c)` Calculates the minimum size dimensions for the specified container, given the components it contains.
`Dimension` | `preferredLayoutSize(Container c)` Calculates the preferred size dimensions for the specified container, given the components it contains.
`void` | `removeLayoutComponent(Component c)` Removes the specified component from the layout.
`void` | `setCentersChildren(boolean newValue)`
`void` | `setPadding(int newPadding)`
`void` | `setSyncAllWidths(boolean newValue)`
