protected class JMenu.AccessibleJMenu extends JMenuItem.AccessibleJMenuItem implements AccessibleSelection
This class implements accessibility support for the
JMenu
class. It provides an implementation of the
Java Accessibility API appropriate to menu 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 JavaBeans
has been added to the java.beans
package.

Method Details

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 classJComponent.AccessibleJComponent
- Returns:
- the number of accessible children in the object.
-
getAccessibleChild
Returns the nth Accessible child of the object.- Overrides:
getAccessibleChild
in classJComponent.AccessibleJComponent
- Parameters:
i
- zero-based index of child- Returns:
- the nth Accessible child of the object
- See Also:
AccessibleContext.getAccessibleChildrenCount()
-
getAccessibleRole
Get the role of this object.- Overrides:
getAccessibleRole
in classJMenuItem.AccessibleJMenuItem
- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:
AccessibleRole
-
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 classAccessibleContext
- 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 interfaceAccessibleSelection
- Returns:
- 1 if a menu is currently selected, else 0
-
getAccessibleSelection
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 interfaceAccessibleSelection
- 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 interfaceAccessibleSelection
- Parameters:
i
- the zero-based index of the child in this Accessible object.- Returns:
true
if the current child of this object is selected; elsefalse
- See Also:
AccessibleContext.getAccessibleChild(int)
-
addAccessibleSelection
public void addAccessibleSelection(int i)Selects thei
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 interfaceAccessibleSelection
- 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 interfaceAccessibleSelection
- 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 interfaceAccessibleSelection
-
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 interfaceAccessibleSelection
