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/setSelectedgetState/setState 都可以用来确定/指定菜单项的选择状态。首选方法是 isSelectedsetSelected,它们可用于所有菜单和按钮。getStatesetState 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
