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 JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.

Constructor Detail

JMenu.AccessibleJMenu

protected JMenu.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
