Package 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 class should be treated as a "protected" inner class. Instantiate it only within subclasses of BasicOptionPaneUI.
