Method Detail

addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener listener)

Adds a property change listener to the list of registered listeners. This sets up the accessibleContainerHandler and accessibleFocusHandler fields and calls super.addPropertyChangeListener(listener).

Parameters:

listener - the listener to add

See Also:

AccessibleContext.ACCESSIBLE_NAME_PROPERTY, AccessibleContext.ACCESSIBLE_DESCRIPTION_PROPERTY, AccessibleContext.ACCESSIBLE_STATE_PROPERTY, AccessibleContext.ACCESSIBLE_VALUE_PROPERTY, AccessibleContext.ACCESSIBLE_SELECTION_PROPERTY, AccessibleContext.ACCESSIBLE_TEXT_PROPERTY, AccessibleContext.ACCESSIBLE_VISIBLE_DATA_PROPERTY

removePropertyChangeListener

public void removePropertyChangeListener(java.beans.PropertyChangeListener listener)

Removes a property change listener from the list of registered listeners. This uninstalls the accessibleContainerHandler and accessibleFocusHandler fields and calls super.removePropertyChangeListener(listener).

Parameters:

listener - the listener to remove

See Also:

AccessibleContext.addPropertyChangeListener(PropertyChangeListener)

getAccessibleChildrenCount

public int getAccessibleChildrenCount()

Returns the number of accessible children of this object.

Returns:

the number of accessible children of this object

See Also:

getAccessibleChild

public javax.accessibility.Accessible getAccessibleChild(int i)

Returns the accessible child component at index i.

Parameters:

i - the index of the accessible child to return

Returns:

the accessible child component at index i

See Also:

getAccessibleChildrenCount()

getAccessibleStateSet

public javax.accessibility.AccessibleStateSet getAccessibleStateSet()

Returns the accessible state set of this component.

Returns:

the accessible state set of this component

See Also:

getAccessibleName

public java.lang.String getAccessibleName()

Returns the localized name for this object. Generally this should almost never return Component.getName() since that is not a localized name. If the object is some kind of text component (like a menu item), then the value of the object may be returned. Also, if the object has a tooltip, the value of the tooltip may also be appropriate.

Returns:

the localized name for this object or null if this object has no name
