All Implemented Interfaces:
  AccessibleComponent, AccessibleExtendedComponent, AccessibleSelection, Serializable

Enclosing class:
  JMenuBar

protected class JMenuBar.AccessibleJMenuBar
extends JComponent.AccessibleJComponent
implements AccessibleSelection

This class implements accessibility support for the `JMenuBar` class. It provides an implementation of the Java Accessibility API appropriate to menu bar 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. As of 1.4, support for long term storage of all JavaBeansTM has been added to the `java.beans` package. Please see `XMLEncoder`.

Constructor Detail

### JMenuBar.AccessibleJMenuBar

    protected JMenuBar.AccessibleJMenuBar()

Method Detail

### getAccessibleStateSet

    public AccessibleStateSet getAccessibleStateSet()

  Get the accessible state set of this object.

  Overrides:
    `getAccessibleStateSet` in class `JComponent.AccessibleJComponent`
  Returns:
    an instance of AccessibleState containing the current state of the object
  See Also:
    `AccessibleState`

### 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`

### 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
  See Also:
    `AccessibleSelection`

### getAccessibleSelectionCount

    public int getAccessibleSelectionCount()

  Returns 1 if a menu is currently selected in this menu bar.

  Specified by:
    `getAccessibleSelectionCount` in interface `AccessibleSelection`
  Returns:
    1 if a menu is currently selected, else 0

### getAccessibleSelection

    public Accessible getAccessibleSelection(int i)

  Returns the currently selected menu if one is selected, otherwise null.

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

### isAccessibleChildSelected

    public boolean isAccessibleChildSelected(int i)

  Returns true 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)

  Selects the nth menu in the menu bar, forcing it to pop up. If another menu is popped up, this will force it to close. If the nth menu is already selected, this method has no effect.

  Specified by:
    `addAccessibleSelection` in interface `AccessibleSelection`
  Parameters:
    `i` - the zero-based index of selectable items
  See Also:
    `getAccessibleStateSet()`

### removeAccessibleSelection

    public void removeAccessibleSelection(int i)

  Removes the nth selected item in the object from the object's selection. If the nth item isn't currently selected, this method has no effect. Otherwise, it closes the popup menu.

  Specified by:
    `removeAccessibleSelection` in interface `AccessibleSelection`
  Parameters:
    `i` - the zero-based index of selectable items
  See Also:
    `AccessibleContext.getAccessibleChild(int)`

### clearAccessibleSelection

    public void clearAccessibleSelection()

  Clears the selection in the object, so that nothing in the object is selected. This will close any open menu.

  Specified by:
    `clearAccessibleSelection` in interface `AccessibleSelection`

### selectAllAccessibleSelection

    public void selectAllAccessibleSelection()

  Normally causes every selected item in the object to be selected if the object supports multiple selections. This method makes no sense in a menu bar, and so does nothing.

  Specified by:
    `selectAllAccessibleSelection` in interface `AccessibleSelection`
