javax.swing
类 JScrollPane.ScrollBar

java.lang.Object
  继承者 java.awt.Component
      继承者 java.awt.Container
          继承者 javax.swing.JComponent
              继承者 javax.swing.JScrollBar
                  继承者 javax.swing.JScrollPane.ScrollBar
所有已实现的接口：
Adjustable, ImageObserver, MenuContainer, Serializable, Accessible, UIResource
正在封闭类：
JScrollPane
protected class JScrollPane.ScrollBar
extends JScrollBar
implements UIResource

默认情况下，JScrollPane 创建的滚动条为此类的实例。Scrollbar 重写 getUnitIncrement 和 getBlockIncrement 方法，所以如果视口的视图为 Scrollable，会要求该视图计算这些值。除非显式设置了单位/块增量。

警告：此类的序列化对象将与以后的 Swing 版本不兼容。当前的序列化支持适用于短期存储或运行相同 Swing 版本的应用程序之间的 RMI。从 1.4 版本开始，已在 java.beans 包中添加了支持所有 JavaBeansTM 长期存储的功能。请参阅 XMLEncoder。
