JCheckBoxMenuItem (Java 2 Platform SE 5.0) - JavaTM 2 Platform Standard Edition 5.0 API 规范中文版
javax.swing
类 JCheckBoxMenuItem
java.lang.Object
java.awt.Component
java.awt.Container
javax.swing.JComponent
javax.swing.AbstractButton
javax.swing.JMenuItem
javax.swing.JCheckBoxMenuItem
- 所有已实现的接口：
- ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, MenuElement, SwingConstants
public class JCheckBoxMenuItem
- extends JMenuItem
- implements SwingConstants, Accessible
可以被选定或取消选定的菜单项。如果被选定，菜单项的旁边通常会出现一个复选标记。如果未被选定或被取消选定，菜单项的旁边就没有复选标记。像常规菜单项一样，复选框菜单项可以有与之关联的文本或图标，或者二者兼而有之。
isSelected/setSelected 或 getState/setState 都可以用来确定/指定菜单项的选择状态。首选方法是 isSelected 和 setSelected，它们可用于所有菜单和按钮。getState 和 setState 方法用于与其他组件集的兼容性。
有关使用复选框菜单项的更多信息和示例，请参阅《The Java Tutorial》中的 How to Use Menus 一节。
警告：此类的序列化对象将与以后的 Swing 版本不兼容。当前的序列化支持适用于短期存储或运行相同 Swing 版本的应用程序之间的 RMI。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。
