implements AccessibleSelection

The class used to obtain the accessible role for this object.

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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

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.

Returns:

the number of accessible children in the object.

Overrides:

getAccessibleChildrenCount in class JComponent.AccessibleJComponent

getAccessibleChild

public Accessible getAccessibleChild(int i)

Return the nth Accessible child of the object.

Parameters:

i - zero-based index of child

Returns:

the nth Accessible child of the object

Overrides:

getAccessibleChild in class JComponent.AccessibleJComponent

getAccessibleRole

public AccessibleRole getAccessibleRole()

Get the role of this object.

Returns:

an instance of AccessibleRole describing the role of the object

Overrides:

getAccessibleRole in class JMenuItem.AccessibleJMenuItem

See Also:

AccessibleRole

getAccessibleSelection

public AccessibleSelection getAccessibleSelection()

Get the AccessibleSelection associated with this object if one exists. Otherwise return null.

Overrides:

getAccessibleSelection in class AccessibleContext

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

isAccessibleChildSelected

public boolean isAccessibleChildSelected(int i)

Returns true if the current child of this object is selected. (i.e. if this child is a pop-ed up sub-menu)

Specified by:

isAccessibleChildSelected in interface AccessibleSelection

Parameters:

i - the zero-based index of the child in this Accessible object.

See Also:

getAccessibleChild

addAccessibleSelection

public void addAccessibleSelection(int i)

Selects the nth menu in the menu. If that item is a sub-menu, 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 poppoed up (selected), this method has no effect.

Specified by:

addAccessibleSelection in interface AccessibleSelection

Parameters:

i - the zero-based index of selectable items

See Also:

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
