- ## Constructor Details

  - ### AccessibleAWTMenuComponent

    protected AccessibleAWTMenuComponent()
    Although the class is abstract, this should be called by all sub-classes.

- ## Method Details

  - ### getAccessibleSelection

    public AccessibleSelection getAccessibleSelection()
    Gets the `AccessibleSelection` associated with this object which allows its `Accessible` children to be selected.
    Overrides:
      `getAccessibleSelection` in class `AccessibleContext`
    Returns:
      `AccessibleSelection` if supported by object; else return `null`
    See Also:
      - `AccessibleSelection`

  - ### getAccessibleName

    public String getAccessibleName()
    Gets the accessible name of this object. This should almost never return `java.awt.MenuComponent.getName`, as that generally isn't a localized name, and doesn't have meaning for the user. If the object is fundamentally a text object (e.g. a menu item), the accessible name should be the text of the object (e.g. "save"). If the object has a tooltip, the tooltip text may also be an appropriate String to return.
    Overrides:
      `getAccessibleName` in class `AccessibleContext`
    Returns:
      the localized name of the object -- can be `null` if this object does not have a name
    See Also:
      - `AccessibleContext.setAccessibleName(String)`

  - ### getAccessibleDescription

    public String getAccessibleDescription()
    Gets the accessible description of this object. This should be a concise, localized description of what this object is - what is its meaning to the user. If the object has a tooltip, the tooltip text may be an appropriate string to return, assuming it contains a concise description of the object (instead of just the name of the object - e.g. a "Save" icon on a toolbar that had "save" as the tooltip text shouldn't return the tooltip text as the description, but something like "Saves the current text document" instead).
    Overrides:
      `getAccessibleDescription` in class `AccessibleContext`
    Returns:
      the localized description of the object -- can be `null` if this object does not have a description
    See Also:
      - `AccessibleContext.setAccessibleDescription(String)`

  - ### getAccessibleRole

    public AccessibleRole getAccessibleRole()
    Gets the role of this object.

      `getAccessibleRole` in class `AccessibleContext`
    Returns:
      an instance of `AccessibleRole` describing the role of the object

    public AccessibleStateSet getAccessibleStateSet()
    Gets the state of this object.
    Specified by:

      - `AccessibleState`

  - ### getAccessibleParent

    public Accessible getAccessibleParent()
    Gets the `Accessible` parent of this object. If the parent of this object implements `Accessible`, this method should simply return `getParent`.
    Overrides:
      `getAccessibleParent` in class `AccessibleContext`
    Returns:
      the `Accessible` parent of this object -- can be `null` if this object does not have an `Accessible` parent

  - ### getAccessibleIndexInParent

    public int getAccessibleIndexInParent()
    Gets the index of this object in its accessible parent.
    Specified by:
      `getAccessibleIndexInParent` in class `AccessibleContext`
    Returns:
      the index of this object in its parent; -1 if this object does not have an accessible parent
    See Also:
      - `getAccessibleParent()`

  - ### getAccessibleChildrenCount

    public int getAccessibleChildrenCount()
    Returns the number of accessible children in the object. If all of the children of this object implement `Accessible`, then this method should return the number of children of this object.
    Specified by:
      `getAccessibleChildrenCount` in class `AccessibleContext`
    Returns:
      the number of accessible children in the object

  - ### getAccessibleChild

    Returns the nth `Accessible` child of the object.
    Specified by:
      `getAccessibleChild` in class `AccessibleContext`

      the `Accessible`, if it exists, at the specified location; else `null`

    Specified by:
      `isFocusTraversable` in interface `AccessibleComponent`
    Returns:
      true if object can accept focus; otherwise false

  - ### requestFocus

    public void requestFocus()
    Requests focus for this object.

  - ### addFocusListener

    public void addFocusListener(FocusListener l)
    Adds the specified focus listener to receive focus events from this component.
    Specified by:
      `addFocusListener` in interface `AccessibleComponent`
    Parameters:
      `l` - the focus listener
    See Also:
      - `AccessibleComponent.removeFocusListener(FocusListener)`

  - ### removeFocusListener

    public void removeFocusListener(FocusListener l)
    Removes the specified focus listener so it no longer receives focus events from this component.
    Specified by:
      `removeFocusListener` in interface `AccessibleComponent`

  - ### 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 object. 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`

  - ### selectAllAccessibleSelection

    public void selectAllAccessibleSelection()
    Causes every child of the object to be selected if the object supports multiple selections.
    Specified by:
      `selectAllAccessibleSelection` in interface `AccessibleSelection`
