java.lang.Object java.awt.Component java.awt.Container javax.swing.JComponent javax.swing.JSeparator
public class JSeparator
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: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 JavaBeansTM 长期存储的功能。请参见 XMLEncoder
。
