public class Radio
implements RadioStyleKeysInterface, ComplexStyleInterface

The Radio is a TransformationBean™ that generates the appropriate HTML 4.0 for creating an HTML Radio input field, which is used for attributes which can take a single value from a set of alternatives.

The Radio Transformation Bean gathers the alternatives from a model via the setModel method. A model must implement the javax.swing.ListModel interface in order to be used.

Accessibility

The Section 508 Accessibility standards, such as making application tasks available through the keyboard, are incorporated into our components to improve usability for all of our software products which benefits every SAS user.

This component is fully compliant with the Web-based standards outlined in Section 508. The compliance is based on producing the correct output, having keyboard equivalent and surfacing the necessary properties to assist consumers of the component to be compliant.

The following keyboard equivalents are supported by this component:

KeyBoard Access	Behavior/Result
TAB	TAB moves the focus to the radio button. Hitting TAB while the radio button has focus will navigate focus to the next tabbable component.
ALT+ACCESSKEY	Pressing ALT+ACCESSKEY will navigate focus to the radio button. The ACCESSKEY indicates the keyboard character used as a shortcut to activate the element.
ARROW KEYS	Arrow keys allow the user to navigate to and select a radio button.

The following properties are provided to assist in making the application using this component accessible:

• AccessKey
• TabIndex
• KeyDown
• KeyPress
• KeyUp

The Radio is one of several TransformationBeans™ that rely on a set of style classes that are used by default when generating the resulting markup language. For more information on style sheets and the default style classes that apply to this TransformationBean™, refer to the AppDev Studio Developer Site. You'll find a useful reference document entitled Cascading Style Sheets, Images, and TransformationBeans™ as well as the TransformationBeans™ Style Sheet Reference.

Note that the toString() method on this class calls the write method, which may have undesirable side effects. See BaseTransformation.toString() for more information. Debuggers often use toString() to show the value of a variable, and this may cause unexpected behavior while debugging

For More Information:

Visit the AppDev Studio Developer's Site to access step-by-step examples, white papers and additional usage information at http://support.sas.com/rnd/appdev/.

Examples for this class may be found on the Examples Site.

JSP custom tags provide an alternative to using the TransformationBeans™. Visit the Custom Tag Library Reference for additional information on the sas:Radio custom tag.

The Radio is one of several TransformationBeans™ that rely on JavaScript to provide some of its functionality. These JavaScript files are including automatically by the tbean. See JavaScriptIncludeHandler for more information about how these files are included and how to customize this behavior. The Radio uses the following JavaScript files:
