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

All Implemented Interfaces:

PropertyChangeListener， Serializable， EventListener， AccessibleComponent， AccessibleExtendedComponent， ChangeListener

Enclosing class:

JScrollPane

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

这个类实现了对 JScrollPane类可访问性支持。它提供了API适当滚动窗格的用户界面元素的可访问性的java实现。

警告：序列化该类的对象与以后的Swing版本不兼容。当前的序列化支持适用于短期贮藏或RMI运行相同Swing版本的应用程序之间。为1.4，为所有JavaBeans™长期存储的支持已被添加到java.beans包。请看XMLEncoder。
