javax.swing.JComponent.AccessibleJComponent

javax.swing.AbstractButton.AccessibleAbstractButton

javax.swing.JToggleButton.AccessibleJToggleButton

所有已实现的接口:

ItemListener, Serializable, EventListener, AccessibleAction, AccessibleComponent, AccessibleExtendedComponent, AccessibleText, AccessibleValue

直接已知的子类:

JCheckBox.AccessibleJCheckBox, JRadioButton.AccessibleJRadioButton

封装类:

JToggleButton

       protected class JToggleButton.AccessibleJToggleButton extends AbstractButton.AccessibleAbstractButton implements ItemListener
      

该类实现了对 JToggleButton 类的辅助功能支持。它提供了适用于切换按钮用户界面元素的 Java Accessibility API 实现。

警告: 该类的序列化对象将不兼容未来的 Swing 发布版。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 版开始，已将对所有 JavaBeans 的长期存储支持添加到 java.beans 包中。请参阅 XMLEncoder。
