All Implemented Interfaces:
  AccessibleAction, AccessibleComponent, AccessibleSelection, Serializable

Enclosing class:
  JComboBox

protected class JComboBox.AccessibleJComboBox
extends JComponent.AccessibleJComponent
implements AccessibleAction, AccessibleSelection

This class implements accessibility support for the `JComboBox` class. It provides an implementation of the Java Accessibility API appropriate to Combo Box user-interface elements.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.

Constructor Detail

### JComboBox.AccessibleJComboBox

    protected JComboBox.AccessibleJComboBox()

Method Detail

### getAccessibleChildrenCount

    public int getAccessibleChildrenCount()

  Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.
  Overrides:
    `getAccessibleChildrenCount` in class `JComponent.AccessibleJComponent`
  Returns:
    the number of accessible children in the object.

### getAccessibleChild

    public Accessible getAccessibleChild(int i)

  Returns the nth Accessible child of the object. The child at index zero represents the popup. If the combo box is editable, the child at index one represents the editor.
  Overrides:
    `getAccessibleChild` in class `JComponent.AccessibleJComponent`
  Parameters:
    `i` - zero-based index of child
  Returns:
    the nth Accessible child of the object

### getAccessibleRole

    public AccessibleRole getAccessibleRole()

  Get the role of this object.
  Overrides:
    `getAccessibleRole` in class `JComponent.AccessibleJComponent`
  Returns:
    an instance of AccessibleRole describing the role of the object
  See Also:
    `AccessibleRole`

### getAccessibleAction

    public AccessibleAction getAccessibleAction()

  Get the AccessibleAction associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleAction interface on behalf of itself.
  Overrides:
    `getAccessibleAction` in class `AccessibleContext`
  Returns:
    this object

### getAccessibleActionDescription

    public String getAccessibleActionDescription(int i)

  Return a description of the specified action of the object.
  Specified by:
    `getAccessibleActionDescription` in interface `AccessibleAction`
  Parameters:
    `i` - zero-based index of the actions

### getAccessibleActionCount

    public int getAccessibleActionCount()

  Returns the number of Actions available in this object. The default behavior of a combo box is to have one action.
  Specified by:
    `getAccessibleActionCount` in interface `AccessibleAction`
  Returns:
    1, the number of Actions in this object

### doAccessibleAction

    public boolean doAccessibleAction(int i)

  Perform the specified Action on the object
  Specified by:
    `doAccessibleAction` in interface `AccessibleAction`
  Parameters:
    `i` - zero-based index of actions
  Returns:
    true if the the action was performed; else false.

### getAccessibleSelection

    public AccessibleSelection getAccessibleSelection()

  Get the AccessibleSelection associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleSelection interface on behalf of itself.
  Overrides:
    `getAccessibleSelection` in class `AccessibleContext`
  Returns:
    this object

### getAccessibleSelectionCount

    public int getAccessibleSelectionCount()

  Returns the number of Accessible children currently selected. If no children are selected, the return value will be 0.
  Specified by:
    `getAccessibleSelectionCount` in interface `AccessibleSelection`
  Returns:
    the number of items currently selected.

### getAccessibleSelection

    public Accessible getAccessibleSelection(int i)

  Returns an Accessible representing the specified selected child in the popup. If there isn't a selection, or there are fewer children selected than the integer passed in, the return value will be null.

  Note that the index represents the i-th selected child, which is different from the i-th child.

  Specified by:
    `getAccessibleSelection` in interface `AccessibleSelection`
  Parameters:
    `i` - the zero-based index of selected children
  Returns:
    the i-th selected child
  See Also:
    `getAccessibleSelectionCount()`

### isAccessibleChildSelected

    public boolean isAccessibleChildSelected(int i)

  Determines if the current child of this object is selected.
  Specified by:
    `isAccessibleChildSelected` in interface `AccessibleSelection`
  Parameters:
    `i` - the zero-based index of the child in this Accessible object.
  Returns:
    true if the current child of this object is selected; else false
  See Also:
    `AccessibleContext.getAccessibleChild(int)`

### addAccessibleSelection

    public void addAccessibleSelection(int i)

  Adds the specified Accessible child of the object to the object's selection. If the object supports multiple selections, the specified child is added to any existing selection, otherwise it replaces any existing selection in the object. If the specified child is already selected, this method has no effect.
  Specified by:
    `addAccessibleSelection` in interface `AccessibleSelection`
  Parameters:
    `i` - the zero-based index of the child
  See Also:
    `AccessibleContext.getAccessibleChild(int)`

### removeAccessibleSelection

    public void removeAccessibleSelection(int i)

  Removes the specified child of the object from the object's selection. If the specified item isn't currently selected, this method has no effect.
  Specified by:
    `removeAccessibleSelection` in interface `AccessibleSelection`
  Parameters:
    `i` - the zero-based index of the child
  See Also:
    `AccessibleContext.getAccessibleChild(int)`

### clearAccessibleSelection

    public void clearAccessibleSelection()

  Clears the selection in the object, so that no children in the object are selected.
  Specified by:
    `clearAccessibleSelection` in interface `AccessibleSelection`
