public class JRadioButton
extends JToggleButton
implements Accessible

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. Tocreate 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.

See How to Use Buttons, Check Boxes, and Radio Buttons in The Java Tutorial for further documentation.

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 JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.

JRadioButton

public JRadioButton(String text)
Creates an unselected radio button with the specified text.

Parameters:
text - the string displayed on the radio button

JRadioButton

public JRadioButton(String text,
                    boolean selected)
Creates a radio button with the specified text and selection state.

Parameters:
text - the string displayed on the radio button
selected - if true, the button is initially selected; otherwise, the button is initially unselected

Method Detail

updateUI

public void updateUI()
Resets the UI property to a value from the current look and feel.

Overrides:
updateUI in class JToggleButton
See Also:
JComponent.updateUI()

getUIClassID

public String getUIClassID()
Returns the name of the L&F class that renders this component.

Overrides:
getUIClassID in class JToggleButton
Returns:
String "RadioButtonUI"
See Also:
JComponent.getUIClassID(), UIDefaults.getUI(javax.swing.JComponent)

configurePropertiesFromAction

protected void configurePropertiesFromAction(Action a)
Factory method which sets the ActionEvent source's properties according to values from the Action instance. The properties which are set may differ for subclasses. By default, the properties which get set are Text, Mnemonic, Enabled, ActionCommand, and ToolTipText.

Overrides:
configurePropertiesFromAction in class AbstractButton
Parameters:
a - the Action from which to get the properties, or null
Since:
1.3
See Also:
Action, AbstractButton.setAction(javax.swing.Action)

createActionPropertyChangeListener

protected PropertyChangeListener createActionPropertyChangeListener(Action a)
Factory method which creates the PropertyChangeListener used to update the ActionEvent source as properties change on its Action instance. Subclasses may override this in order to provide their own PropertyChangeListener if the set of properties which should be kept up to date differs from the default properties (Text, Icon, Enabled, ToolTipText). Note that PropertyChangeListeners should avoid holding strong references to the ActionEvent source, as this may hinder garbage collection of the ActionEvent source and all components in its containment hierarchy.

Overrides:
createActionPropertyChangeListener in class AbstractButton
Parameters:
a - the new action for the button
Since:
1.3
See Also:
Action, AbstractButton.setAction(javax.swing.Action)

paramString

protected String paramString()
Returns a string representation of this JRadioButton. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Overrides:
paramString in class JToggleButton
Returns:
a string representation of this JRadioButton.

getAccessibleContext

public AccessibleContext getAccessibleContext()
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.

Specified by:
getAccessibleContext in interface Accessible
Overrides:
getAccessibleContext in class JToggleButton
Returns:
an AccessibleJRadioButton that serves as the AccessibleContext of this JRadioButton

Remarques

Contenu

Le contenu de cette page provient du site de Sun, et est généré depuis un cache sur l'infobrol après certains traitements automatisés. La présentation peut donc différer du document original, mais le contenu aussi. Vous pouvez utiliser ce bouton pour afficher la page originale du site de Sun :

Quels sont les motivations de cette démarche?

Maintenir les pages en cache sur différents sites peut offrir plus de disponibilité.

Chaque page est indexée dans la base de donnée, ce qui permet de retrouver facilement les informations, au moyen des sommaires, du moteur de recherche interne, etc.

Des facilités sont mises en place pour que les membres de l'infobrol puissent effectuer des traductions en français des différents documents. Ceci devrait permettre aux débutants en programmation Java de consulter les API en français s'ils maîtrisent moins bien la langue de Shakespeare. Dans le cas où une traduction a été soumise, elle est disponible au moyen d'un lien en bas de page. Si la traduction a été validée, la page s'affiche par défaut en français, et un lien en bas de page permet d'atteindre la version en anglais.

Le code sur l'infobrol est automatiquement coloré selon la syntaxe, et les différents mots clés sont transformés en liens pour accéder rapidement aux informations.

Vous avez la possibilité de partager vos expériences en proposant vos propres extraits de code en utilisant le bouton "ajouter un commentaire" en bas de page. Si vous visitez simplement l'infobrol, vous avez déjà accès à cette fonction, mais si vous étes membre du brol, vous pouvez en plus utiliser des boutons supplémentaires de mise en forme, dont la coloration automatique de vos extraits de codes.
