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. Please see XMLEncoder

protected AccessibleJMenu()
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.
getAccessibleChildrenCount
in class JComponent.AccessibleJComponent
public Accessible getAccessibleChild(int i)
Returns the nth Accessible child of the object.
getAccessibleChild
in class JComponent.AccessibleJComponent
i
- zero-based index of childAccessibleContext.getAccessibleChildrenCount()
public AccessibleRole getAccessibleRole()
Get the role of this object.
getAccessibleRole
in class JMenuItem.AccessibleJMenuItem
AccessibleRole
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.
getAccessibleSelection
in class AccessibleContext
AccessibleSelection
public int getAccessibleSelectionCount()
Returns 1 if a sub-menu is currently selected in this menu.
getAccessibleSelectionCount
in interface AccessibleSelection
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).
getAccessibleSelection
in interface AccessibleSelection
i
- the zero-based index of selected childrenAccessibleSelection.getAccessibleSelectionCount()
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).
isAccessibleChildSelected
in interface AccessibleSelection
i
- the zero-based index of the child in this Accessible object.AccessibleContext.getAccessibleChild(int)
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.
addAccessibleSelection
in interface AccessibleSelection
i
- the index of the item to be selectedAbstractButton.AccessibleAbstractButton.getAccessibleStateSet()
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).
removeAccessibleSelection
in interface AccessibleSelection
i
- the zero-based index of the selected itemAccessibleContext.getAccessibleChild(int)
public void clearAccessibleSelection()
Clears the selection in the object, so that nothing in the object is selected. This will close any open sub-menu.
clearAccessibleSelection
in interface AccessibleSelection
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.
