All Implemented Interfaces:

Serializable, AccessibleComponent, AccessibleExtendedComponent, AccessibleSelection

Enclosing class:

JMenuBar

protected class JMenuBar.AccessibleJMenuBar
extends JComponent.AccessibleJComponent
implements AccessibleSelection

This class implements accessibility support for the JMenuBar class. It provides an implementation of the Java Accessibility API appropriate to menu bar 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^TM has been added to the java.beans package. Please see {@link java.beans.XMLEncoder}.

JMenuBar.AccessibleJMenuBar

protected JMenuBar.AccessibleJMenuBar()

addAccessibleSelection

public void addAccessibleSelection(int i)

Selects the nth menu in the menu bar, forcing it to pop up. If another menu is popped up, this will force it to close. If the nth menu is already selected, this method has no effect.

Parameters:

i - the zero-based index of selectable items

clearAccessibleSelection

public void clearAccessibleSelection()

Clears the selection in the object, so that nothing in the object is selected. This will close any open menu.

getAccessibleRole

public AccessibleRole getAccessibleRole()

Get the role of this object.

Overrides:

getAccessibleRole in class JComponent.AccessibleJComponent

Returns:

an instance of AccessibleRole describing the role of the object

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

getAccessibleSelection

public Accessible getAccessibleSelection(int i)

Returns the currently selected menu if one is selected, otherwise null.

Parameters:

i

getAccessibleSelectionCount

public int getAccessibleSelectionCount()

Returns 1 if a menu is currently selected in this menu bar.

Returns:

1 if a menu is currently selected, else 0

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()

Get the accessible state set of this object.

Overrides:

getAccessibleStateSet in class JComponent.AccessibleJComponent

Returns:

an instance of AccessibleState containing the current state of the object

isAccessibleChildSelected

public boolean isAccessibleChildSelected(int i)

Returns true if the current child of this object is selected.

Parameters:

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

removeAccessibleSelection

public void removeAccessibleSelection(int i)

Removes the nth selected item in the object from the object's selection. If the nth item isn't currently selected, this method has no effect. Otherwise, it closes the popup menu.

Parameters:

i - the zero-based index of selectable items

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.
