Class JMenuItem.AccessibleJMenuItem

java.lang.Object

javax.accessibility.AccessibleContext

java.awt.Component.AccessibleAWTComponent

java.awt.Container.AccessibleAWTContainer

javax.swing.JComponent.AccessibleJComponent

javax.swing.AbstractButton.AccessibleAbstractButton

javax.swing.JMenuItem.AccessibleJMenuItem

所有已实现的接口:

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

直接已知的子类:

JCheckBoxMenuItem.AccessibleJCheckBoxMenuItem, JMenu.AccessibleJMenu, JRadioButtonMenuItem.AccessibleJRadioButtonMenuItem

封装类:

JMenuItem

       protected class JMenuItem.AccessibleJMenuItem extends AbstractButton.AccessibleAbstractButton implements ChangeListener
      

该类实现了对 JMenuItem 类的辅助支持。它提供了适用于菜单项用户界面元素的 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，已将对所有 JavaBeans 的长期存储支持添加到 java.beans 包中。请参阅 XMLEncoder。
