Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`addAccessibleSelection(int i)`	Selects the `i`th menu in the menu.
`void`	`clearAccessibleSelection()`	Clears the selection in the object, so that nothing in the object is selected.
`Accessible`	`getAccessibleChild(int i)`	Returns the nth Accessible child of the object.
`int`	`getAccessibleChildrenCount()`	Returns the number of accessible children in the object.
`AccessibleRole`	`getAccessibleRole()`	Get the role of this object.
`AccessibleSelection`	`getAccessibleSelection()`	Get the AccessibleSelection associated with this object.
`Accessible`	`getAccessibleSelection(int i)`	Returns the currently selected sub-menu if one is selected, otherwise null (there can only be one selection, and it can only be a sub-menu, as otherwise menu items don't remain selected).
`int`	`getAccessibleSelectionCount()`	Returns 1 if a sub-menu is currently selected in this menu.
`boolean`	`isAccessibleChildSelected(int i)`	Returns true if the current child of this object is selected (that is, if this child is a popped-up submenu).
`void`	`removeAccessibleSelection(int i)`	Removes the nth item from the selection.
`void`	`selectAllAccessibleSelection()`	Normally causes every selected item in the object to be selected if the object supports multiple selections.

protected AccessibleJMenu()
```
- 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.
    Overrides:
    getAccessibleChild in class JComponent.AccessibleJComponent
    Parameters:
    i - zero-based index of child
    Returns:
    the nth Accessible child of the object
    See Also:
    AccessibleContext.getAccessibleChildrenCount()
  - getAccessibleRole
```
public AccessibleRole getAccessibleRole()
```
    Get the role of this object.
    Overrides:
    getAccessibleRole in class JMenuItem.AccessibleJMenuItem
    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 sub-menu is currently selected in this menu.
    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 sub-menu if one is selected, otherwise null (there can only be one selection, and it can only be a sub-menu, as otherwise menu items don't remain selected).
    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 (that is, if this child is a popped-up submenu).
    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 ith menu in the menu. If that item is a submenu, it will pop up in response. If a different item is already popped up, this will force it to close. If this is a sub-menu that is already popped up (selected), this method has no effect.
    Specified by:
    addAccessibleSelection in interface AccessibleSelection
    Parameters:
    i - the index of the item to be selected
    See Also:
    AbstractButton.AccessibleAbstractButton.getAccessibleStateSet()
  - removeAccessibleSelection
```
public void removeAccessibleSelection(int i)
```
    Removes the nth item from the selection. In general, menus can only have one item within them selected at a time (e.g. one sub-menu popped open).
    Specified by:
    removeAccessibleSelection in interface AccessibleSelection
    Parameters:
    i - the zero-based index of the selected item
    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 sub-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
