javax.swing
类 JSeparator

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JSeparator

所有已实现的接口：: ImageObserver, MenuContainer, Serializable, Accessible, SwingConstants

直接已知子类：: JPopupMenu.Separator, JToolBar.Separator

public class JSeparator
extends JComponent

implements SwingConstants, Accessible
extends JComponent
implements SwingConstants, Accessible

JSeparator 为实现分隔线提供了一个通用组件 - 通常用作菜单项之间的分隔符，以便将菜单项分成几个逻辑组。可以使用 JMenu 或者 JPopupMenu 的 addSeparator 方法来创建和添加一个分隔符，而不是直接使用 JSeparator。JSeparator 还可能用于 GUI 中任何一个需要可视化分隔符的地方。

有关更多信息和示例，请参阅《The Java Tutorial》中的 How to Use Menus 一节。

警告：此类的已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 JavaBeans^TM 长期存储的功能。请参见 XMLEncoder。
