```
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.

JavaFX 8u40

- Enum Constant Detail
  - BLOCK_DECREMENT
```
public static final AccessibleAction BLOCK_DECREMENT
```
    Request that the node be decremented by a large value. A smaller decrement is requested using DECREMENT.
    Used by Slider, ScrollBar, and others
  - BLOCK_INCREMENT
```
public static final AccessibleAction BLOCK_INCREMENT
```
    Request that the node be incremented by a large value. A smaller increment is requested using INCREMENT.
    Used by Slider, ScrollBar, and others
  - COLLAPSE
```
public static final AccessibleAction COLLAPSE
```
    Request that the node should become collapsed.
    Used by TreeItem, TitledPane, and others
  - DECREMENT
```
public static final AccessibleAction DECREMENT
```
    Request that the node be decremented by a small value. A larger decrement is requested using BLOCK_DECREMENT.
    Used by Slider, ScrollBar, and others
  - EXPAND
```
public static final AccessibleAction EXPAND
```
    Request that the node should become expanded.
    Used by TreeItem, TitledPane, and others
  - FIRE
```
public static final AccessibleAction 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
```
public static final AccessibleAction INCREMENT
```
    Request that the node be incremented by a small value. A larger increment is requested using BLOCK_INCREMENT.
    Used by Slider, ScrollBar, and others
  - REQUEST_FOCUS
```
public static final AccessibleAction REQUEST_FOCUS
```
    Request that the node take focus. By default, a node will request focus using Node.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
```
public static final AccessibleAction SHOW_ITEM
```
    Request the node to show an item, scrolling if required.
    Used by ListView, TreeView, and others
    Parameters:
    
    Node the item to show
  - SHOW_TEXT_RANGE
```
public static final AccessibleAction SHOW_TEXT_RANGE
```
    Request the node to show a text range, scrolling if required.
    Used by TextField and TextArea.
    Parameters:
    
    Integer the start offset
    
    Integer the end offset
  - SET_SELECTED_ITEMS
```
public static final AccessibleAction SET_SELECTED_ITEMS
```
    Request the node to set the selection to a list of items.
    Used by ListView, TreeView, and others
    Parameters:
    
    ObservableList<Node> the items to select
  - SET_TEXT_SELECTION
```
public static final AccessibleAction SET_TEXT_SELECTION
```
    Request the node to set the selection to range of text.
    Used by TextField and TextArea.
    Parameters:
    
    Integer the start offset
    
    Integer the end offset
  - SET_TEXT
```
public static final AccessibleAction SET_TEXT
```
    Request the node to set the current text.
    Used by TextField and TextArea.
    Parameters:
    
    String the new text
  - SET_VALUE
```
public static final AccessibleAction SET_VALUE
```
    Request the node to set the current value.
    Used by Slider, Scrollbars, and others
    Parameters:
    
    Double the new value
  - SHOW_MENU
```
public static final AccessibleAction SHOW_MENU
```
    Request the node to show a menu. If the node is a control, then the context menu for the control is shown. If the node is a menu, then the submenu for the menu is shown.
    Used by Node, Menu

    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static AccessibleAction valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
