protected class JSlider.AccessibleJSlider
extends JComponent.AccessibleJComponent
implements AccessibleValue, ChangeListener, AccessibleAction
This class implements accessibility support for the
JSlider class. It provides an implementation of the
Java Accessibility API appropriate to slider user-interface elements.
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.

getAccessibleRolein classJComponent.AccessibleJComponent- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:
-
getAccessibleValue
Get the AccessibleValue associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleValue interface on behalf of itself.- Overrides:
getAccessibleValuein classAccessibleContext- Returns:
- this object
- See Also:

- AccessibleAction if supported by object; else return null
- See Also:
-
getAccessibleActionCount
public int getAccessibleActionCount()Returns the number of accessible actions available in this object If there are more than one, the first one is considered the "default" action of the object. Two actions are supported: AccessibleAction.INCREMENT which increments the slider value and AccessibleAction.DECREMENT which decrements the slider value- Specified by:
getAccessibleActionCountin interfaceAccessibleAction- Returns:
- the zero-based number of Actions in this object
-
getAccessibleActionDescription
Returns a description of the specified action of the object.- Specified by:
getAccessibleActionDescriptionin interfaceAccessibleAction- Parameters:
i- zero-based index of the actions- Returns:
- a String description of the action
- See Also:
-
doAccessibleAction
public boolean doAccessibleAction(int i) Performs the specified Action on the object- Specified by:
doAccessibleActionin interfaceAccessibleAction- Parameters:
i- zero-based index of actions. The first action (index 0) is AccessibleAction.INCREMENT and the second action (index 1) is AccessibleAction.DECREMENT.- Returns:
- true if the action was performed, otherwise false
