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.
