Class JScrollPane.AccessibleJScrollPane

java.lang.Object

javax.accessibility.AccessibleContext

java.awt.Component.AccessibleAWTComponent

java.awt.Container.AccessibleAWTContainer

javax.swing.JComponent.AccessibleJComponent

javax.swing.JScrollPane.AccessibleJScrollPane

所有已实现的接口:

PropertyChangeListener, Serializable, EventListener, AccessibleComponent, AccessibleExtendedComponent, ChangeListener

封装类:

JScrollPane

       protected class JScrollPane.AccessibleJScrollPane extends JComponent.AccessibleJComponent implements ChangeListener, PropertyChangeListener
      

该类为JScrollPane类实现了辅助功能支持。它提供了适用于滚动窗格用户界面元素的Java辅助功能API的实现。

警告: 该类的序列化对象将不兼容未来的Swing版本。当前的序列化支持适用于短期存储或在运行相同Swing版本的应用程序之间的RMI。从1.4版本开始，已将所有JavaBeans的长期存储支持添加到java.beans包中。请参阅XMLEncoder。
