public enum AccessibleAction extends Enum<AccessibleAction>
This enum describes the actions that an assistive technology
such as a screen reader can request from the scene graph.
The
AccessibleRole
dictates the set of actions that
the screen reader will request for a particular control. For
example, a push button normally fires an event to indicate
that it was pressed in response to the FIRE action.
An action may have any number of parameters, depending on the particular action.

Enum Constant Details
-
BLOCK_DECREMENT
Request that the node be decremented by a large value. A smaller decrement is requested usingDECREMENT
.Used by Slider, ScrollBar, and others
-
BLOCK_INCREMENT
Request that the node be incremented by a large value. A smaller increment is requested usingINCREMENT
.Used by Slider, ScrollBar, and others
-
COLLAPSE
Request that the node should become collapsed.Used by TreeItem, TitledPane, and others
-
DECREMENT
Request that the node be decremented by a small value. A larger decrement is requested usingBLOCK_DECREMENT
.Used by Slider, ScrollBar, and others
-
EXPAND
Request that the node should become expanded.Used by TreeItem, TitledPane, and others
-
FIRE
Fires the primary action for the node. For example, a push button will normally send an action event to notify listeners that is has been activated.Used by Button, Hyperlink, and others
-
INCREMENT
Request that the node be incremented by a small value. A larger increment is requested usingBLOCK_INCREMENT
.Used by Slider, ScrollBar, and others
-
REQUEST_FOCUS
Request that the node take focus. By default, a node will request focus usingNode.requestFocus()
. Both JavaFX and the assisteve technology have the concept of a focus node and most of the time, they are the same. In some cases, a control might want the JavaFX focus to remain on the parent, while the assistive technology focus is on the child. For example, a table may respond to this request by setting focus to a cell inside the table before allowing the default to run.Used by Node, TabItem, TableCell and others
-
SHOW_ITEM

-
-
SET_VALUE
