This class implements accessibility support for the
JMenu

JMenu.AccessibleJMenu
protected JMenu.AccessibleJMenu()
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
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
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
- Following copied from interface:
javax.accessibility.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.- See Also:
AccessibleContext.getAccessibleChild(int)
addAccessibleSelection
public void addAccessibleSelection(int i)
- Selects the
i
th 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
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
