Class JTextArea.AccessibleJTextArea

java.lang.Object

javax.accessibility.AccessibleContext

java.awt.Component.AccessibleAWTComponent

java.awt.Container.AccessibleAWTContainer

javax.swing.JComponent.AccessibleJComponent

javax.swing.text.JTextComponent.AccessibleJTextComponent

javax.swing.JTextArea.AccessibleJTextArea

所有已实现的接口:

Serializable, EventListener, AccessibleAction, AccessibleComponent, AccessibleEditableText, AccessibleExtendedComponent, AccessibleExtendedText, AccessibleText, CaretListener, DocumentListener

封装类:

JTextArea

       protected class JTextArea.AccessibleJTextArea extends JTextComponent.AccessibleJTextComponent
      

该类实现了对JTextArea类的辅助功能支持。它提供了适用于文本区域用户界面元素的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。
