Enum AccessibleAction

java.lang.Object
  • java.lang.Enum<AccessibleAction>
    • javafx.scene.AccessibleAction

All Implemented Interfaces:

Serializable, Comparable<AccessibleAction>



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.

Since:

JavaFX 8u40

    • 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

      Parameters:
    • 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

      Parameters:
    • COLLAPSE

      public static final AccessibleAction COLLAPSE
      Request that the node should become collapsed.

      Used by TreeItem, TitledPane, and others

      Parameters:
    • 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

      Parameters:
    • EXPAND

      public static final AccessibleAction EXPAND
      Request that the node should become expanded.

      Used by TreeItem, TitledPane, and others

      Parameters:
    • 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

      Parameters:
    • 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

      Parameters:
    • 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

      Parameters:
    • 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

    • values

      public static AccessibleAction[] values()
      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
      for (AccessibleAction c : AccessibleAction.values())
          System.out.println(c);
