Enum AccessibleAttribute

java.lang.Object
java.lang.Enum<AccessibleAttribute>
javafx.scene.AccessibleAttribute
All Implemented Interfaces:
Serializable, Comparable<AccessibleAttribute>

public enum AccessibleAttribute extends Enum<AccessibleAttribute>
This enum describes the attributes that an assistive technology such as a screen reader can request from the scene graph. The AccessibleRole dictates the set of attributes that the screen reader will request for a particular control. For example, a slider is expected to return a double that represents the current value.

Attributes may have any number of parameters, depending on the particular attribute.

When the value of an attribute is changed by a node, it must notify the assistive technology using

invalid @link
Node#notifyAccessibleAttributeChanged(AccessibleAttribute)
. This will allow the screen reader to inform the user that a value has changed. The most common form of notification is focus change.
