java.lang.Object java.awt.Component java.awt.Container javax.swing.JComponent javax.swing.AbstractButton javax.swing.JToggleButton javax.swing.JRadioButton
public class JRadioButton
实现一个单选按钮,此按钮项可被选择或取消选择,并可为用户显示其状态。与 ButtonGroup
对象配合使用可创建一组按钮,一次只能选择其中的一个按钮。(创建一个 ButtonGroup 对象并用其 add
方法将 JRadioButton 对象包含在此组中。)
注:ButtonGroup 对象为逻辑分组,不是物理分组。要创建按钮面板,仍需要创建一个JPanel
或类似的容器对象并将Border
添加到其中以便将面板与周围的组件分开。
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。
有关更多内容,请参阅 The Java Tutorial 中的 How to Use Buttons, Check Boxes, and Radio Buttons。
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
