JRadioButtonMenuItem (Java Platform SE 6) - JavaTM 2 Platform Standard Edition 6.0 API 规范中文版
javax.swing
类 JRadioButtonMenuItem
java.lang.Object
java.awt.Component
java.awt.Container
javax.swing.JComponent
javax.swing.AbstractButton
javax.swing.JMenuItem
javax.swing.JRadioButtonMenuItem
- 所有已实现的接口:
- ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, MenuElement, SwingConstants
public class JRadioButtonMenuItem
- extends JMenuItem
- implements Accessible
一个单选按钮菜单项的实现。JRadioButtonMenuItem
是属于一组菜单项中的一个菜单项,该组中只能选择一个项。被选择的项显示其选择状态。选择此项的同时,其他任何以前被选择的项都切换到未选择状态。要控制一组单选按钮菜单项的选择状态,请使用 ButtonGroup
对象。
通过 Action
可以配置菜单项,并进行一定程度的控制。对菜单项使用 Action
有许多直接配置菜单项所不及的优点。有关更多信息,请参阅支持 Action
的 Swing 组件,可以在 The Java Tutorial 中的 How
to Use Actions 一节找到更多信息。
有关更多内容和示例,请参阅 The Java Tutorial 中的 How to Use Menus 一节。
警告:Swing 不是线程安全的。有关更多信息,请参阅 Swing's Threading
Policy。
警告:此类的序列化对象与以后的 Swing 版本不兼容。当前序列化支持适用于短期存储,或适用于在运行相同 Swing 版本的应用程序之间进行 RMI(Remote Method Invocation,远程方法调用)。从 1.4 版本开始,已在 java.beans
包中添加了支持所有 JavaBeansTM 长期存储的功能。请参见 XMLEncoder
。
