Interface AccessibleValue
- All Known Implementing Classes:
- Button.AccessibleAWTButton, Checkbox.AccessibleAWTCheckbox, CheckboxMenuItem.AccessibleAWTCheckboxMenuItem, MenuItem.AccessibleAWTMenuItem, Scrollbar.AccessibleAWTScrollBar, AbstractButton.AccessibleAbstractButton, JInternalFrame.AccessibleJInternalFrame, JInternalFrame.JDesktopIcon.AccessibleJDesktopIcon, JSplitPane.AccessibleJSplitPane, JScrollBar.AccessibleJScrollBar, JProgressBar.AccessibleJProgressBar, JSlider.AccessibleJSlider
- public interface AccessibleValue
The AccessibleValue interface should be supported by any object
that supports a numerical value (e.g., a scroll bar). This interface
provides the standard mechanism for an assistive technology to determine
and set the numerical value as well as get the minimum and maximum values.
Applications can determine
if an object supports the AccessibleValue interface by first
obtaining its AccessibleContext (see
Accessible) and then calling the
AccessibleContext.getAccessibleValue() method.
If the return value is not null, the object supports this interface.
