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 pushbutton. Hitting TAB while the pushbutton has focus will navigate focus to the next tabbable component.
ALT+ACCESSKEY	Pressing ALT+ACCESSKEY will navigate focus to the pushbutton. The ACCESSKEY indicates the keyboard character used as a shortcut to activate the element.
ALT+RIGHT ARROW	Pressing the ALT+RIGHT ARROW while the pushbutton has focus, presses the pushbutton.
ENTER	Pressing ENTER while the pushbutton has focus, presses the pushbutton.

The following keyboard equivalents are supported by this component:

KeyBoard Access	Behavior/Result
Tab	Navigate to the PushButton to give it focus
Alt + AccessKey	Gives the PushButton focus
Alt + RightArrow key	To press the PushButton
Enter key	To press the PushButton

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

• AccessKey
• TabIndex
• KeyDown
• KeyPress
• KeyUp

The PushButton 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:PushButton custom tag.
