@JavaBean(defaultProperty="UIClassID",
          description="An implementation of a two-state button.")
public class JToggleButton
extends AbstractButton
implements Accessible

一个两状态按钮的实现。 JRadioButton和JCheckBox类是JCheckBox的子类。 有关使用它们的信息，请参阅“Java教程”中的“ How to Use Buttons, Check Boxes, and Radio Buttons ”一节。

按钮可以配置，并在一定程度上由Action s控制。 使用带按钮的Action除了直接配置按钮之外，还有很多好处。 有关更多详细信息，请参阅Swing Components Supporting Action ，您可以在“Java教程”一节中的 How to Use Actions中找到更多信息。

警告： Swing不是线程安全的。 有关详细信息，请参阅Swing's Threading Policy 。

警告：此类的序列化对象与将来的Swing版本不兼容。 当前的序列化支持适用于运行相同版本的Swing的应用程序之间的短期存储或RMI。 从1.4开始，支持所有JavaBeans的长期存储已被添加到java.beans包中。 请参阅XMLEncoder 。

从以下版本开始：

1.2

重写：

updateUI中的 AbstractButton

另请参见：

JComponent.updateUI()

getUIClassID

@BeanProperty(bound=false,
              description="A string that specifies the name of the L&F class")
public String getUIClassID()
