javax.swing.JRadioButton
An implementation of a radio button -- an item that can be selected or deselected, and which displays its state to the user. Used with a ButtonGroup object to create a group of buttons in which only one button at a time can be selected. (Create a ButtonGroup object and use its add method to include the JRadioButton objects in the group.)
Note: The ButtonGroup object is a logical grouping -- not a physical grouping. To create a button panel, you should still create a JPanel or similar container-object and add a Border to it to set it off from surrounding components.
Buttons can be configured, and to some degree controlled, by Actions. Using an Action with a button has many benefits beyond directly configuring a button. Refer to Swing Components Supporting Action for more details, and you can find more information in How to Use Actions, a section in The Java Tutorial.
See How to Use Buttons, Check Boxes, and Radio Buttons in The Java Tutorial for further documentation.
Warning: Swing is not thread safe. For more information see Swing's Threading Policy.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

Constructor. Creates a radio button that has the specified text, image, and selection state. text - the string displayed on the radio button - `java.lang.String` icon - the image that the button should display - `javax.swing.Icon` selected - `boolean`
get-accessible-contextclj
(get-accessible-context this)Gets the AccessibleContext associated with this JRadioButton. For JRadioButtons, the AccessibleContext takes the form of an AccessibleJRadioButton. A new AccessibleJRadioButton instance is created if necessary.
returns: an AccessibleJRadioButton that serves as the
AccessibleContext of this JRadioButton - javax.accessibility.AccessibleContext
Gets the AccessibleContext associated with this JRadioButton.
For JRadioButtons, the AccessibleContext takes the form of an
AccessibleJRadioButton.
A new AccessibleJRadioButton instance is created if necessary.
returns: an AccessibleJRadioButton that serves as the
AccessibleContext of this JRadioButton - `javax.accessibility.AccessibleContext`get-ui-class-idclj
(get-ui-class-id this)Returns the name of the L&F class that renders this component.
returns: String "RadioButtonUI" - java.lang.String
Returns the name of the L&F class that renders this component. returns: String "RadioButtonUI" - `java.lang.String`
update-uiclj
(update-ui this)Resets the UI property to a value from the current look and feel.
