JavaTM 2 Platform Standard Edition 5.0 API 规范中文版
JRadioButton (Java 2 Platform SE 5.0) - JavaTM 2 Platform Standard Edition 5.0 API 规范中文版
javax.swing
类 JRadioButton
java.lang.Object
java.awt.Component
java.awt.Container
javax.swing.JComponent
javax.swing.AbstractButton
javax.swing.JToggleButton
javax.swing.JRadioButton
- 所有已实现的接口：
- ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, SwingConstants
public class JRadioButton
- extends JToggleButton
- implements Accessible
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。
有关进一步的内容，请参阅《The Java Tutorial》中的 How to Use Buttons, Check Boxes, and Radio Buttons。
警告：此类的序列化对象将与以后的 Swing 版本不兼容。当前的序列化支持适用于短期存储或运行相同 Swing 版本的应用程序之间的 RMI。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。

JRadioButton
public JRadioButton()
- 创建一个初始化为未选择的单选按钮，其文本未设定。
JRadioButton
public JRadioButton(Icon icon)
- 创建一个初始化为未选择的单选按钮，其具有指定的图像但无文本。
- 参数：
icon - 此按钮应显示的图像
JRadioButton
public JRadioButton(Action a)
- 创建一个单选按钮，其属性来自提供的 Action。
- 从以下版本开始：
- 1.3
JRadioButton
public JRadioButton(Icon icon,
boolean selected)
- 创建一个具有指定图像和选择状态的单选按钮，但无文本。
- 参数：
icon - 此按钮应显示的图像selected - 如果为 true，按钮被初始化为选择；否则，按钮被初始化为未选择
JRadioButton
public JRadioButton(String text)
- 创建一个具有指定文本的状态为未选择的单选按钮。
- 参数：
text - 单选按钮上显示的字符串
JRadioButton
public JRadioButton(String text,
boolean selected)
- 创建一个具有指定文本和选择状态的单选按钮。
- 参数：
text - 单选按钮上显示的字符串selected - 如果为 true，按钮被初始化为选择；否则，按钮被初始化为未选择
JRadioButton
public JRadioButton(String text,
Icon icon)
- 创建一个具有指定的文本和图像并初始化为未选择的单选按钮。
- 参数：
text - 此单选按钮上显示的字符串icon - 此按钮应显示的图像
JRadioButton
public JRadioButton(String text,
Icon icon,
boolean selected)
- 创建一个具有指定的文本、图像和选择状态的单选按钮。
- 参数：
text - 此单选按钮上显示的字符串icon - 此按钮应显示的图像
updateUI
public void updateUI()
- 将 UI 属性重置为当前外观对应的值。
- 覆盖：
- 类
JToggleButton 中的 updateUI
- 另请参见：
JComponent.updateUI()
getUIClassID
public String getUIClassID()
- 返回呈现此组件的 L&F 类的名称。
- 覆盖：
- 类
JToggleButton 中的 getUIClassID
- 返回：
- "RadioButtonUI" 字符串
- 另请参见：
JComponent.getUIClassID(),
UIDefaults.getUI(javax.swing.JComponent)
configurePropertiesFromAction
protected void configurePropertiesFromAction(Action a)
- 该工厂方法根据 Action 实例中的值设置
ActionEvent 源的属性。对于子类，设置的属性可能不同。默认情况下，设置的属性为 Text、Mnemonic、Enabled、ActionCommand 和 Mnemonic。
- 覆盖：
- 类
AbstractButton 中的 configurePropertiesFromAction
- 参数：
a - 要从其获得属性的 Action，或为 null- 从以下版本开始：
- 1.3

Action,
AbstractButton.setAction(javax.swing.Action)
createActionPropertyChangeListener
protected PropertyChangeListener createActionPropertyChangeListener(Action a)
- 该工厂方法创建 PropertyChangeListener，当属性在其 Action 实例中更改时，用于更新 ActionEvent 源。如果子类应当保持更新的属性组不同于默认属性（Text、Icon、Enabled、ToolTipText），则可以重写此方法以提供它们自己的 PropertyChangeListener。
注意，PropertyChangeListener 应该避免保持对 ActionEvent 源的强引用，因为这可能妨碍 ActionEvent 源及其容积分层结构中所有组件的垃圾回收。
- 覆盖：
- 类
AbstractButton 中的 createActionPropertyChangeListener
- 参数：
a - 按钮的新操作- 从以下版本开始：
- 1.3
- 另请参见：

null。
- 覆盖：
- 类
JToggleButton 中的 paramString
- 返回：
- 此 JRadioButton 的字符串表示形式。
getAccessibleContext
public AccessibleContext getAccessibleContext()
- 获取与此 JRadioButton 相关联的 AccessibleContext。对于 JRadioButton，AccessibleContext 采用 AccessibleJRadioButton 的形式。必要时创建新的 AccessibleJRadioButton 实例。
- 指定者：
- 接口
Accessible 中的 getAccessibleContext - 覆盖：
- 类
JToggleButton 中的 getAccessibleContext
- 返回：
- 一个 AccessibleJRadioButton，它将充当此 JRadioButton 的 AccessibleContext
