所有已实现的接口：

ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, SwingConstants

直接已知子类：

JCheckBox, JRadioButton

public class JToggleButton
extends AbstractButton
implements Accessible

具有两个状态的（two-state）按钮的实现。JRadioButton 和 JCheckBox 类是此类的子类。有关如何使用按钮，请参阅 The Java Tutorial 中的 How to Use Buttons, Check Boxes, and Radio Buttons 一节。

通过 Action 可以配置按钮，并进行一定程度的控制。对按钮使用 Action 有许多直接配置按钮所不及的优点。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。

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 JavaBeans^TM 长期存储的功能。请参见 XMLEncoder。
