Enum Class AccessibleAttribute

java.lang.Object

java.lang.Enum<AccessibleAttribute>

javafx.scene.AccessibleAttribute

All Implemented Interfaces:: Serializable, Comparable<AccessibleAttribute>, Constable

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 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.
