Field Detail

accessibleContainerHandler

protected ContainerListener accessibleContainerHandler

Receives notification when a child component is added to the JComponent and fires a PropertyChangeEvent on listeners registered with the AccessibleJComponent.

UNKNOWN: AccessibleAWTContainer has a protected field with the same name. Looks like a bug or nasty misdesign to me.

accessibleFocusHandler

protected FocusListener accessibleFocusHandler

Receives notification if the focus on the JComponent changes and fires appropriate PropertyChangeEvents to listeners registered with the AccessibleJComponent.

UNKNOWN: AccessibleAWTComponent has a protected field accessibleAWTFocusHandler. Looks like a bug or nasty misdesign to me.

Method Detail

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

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

Parameters: listener the listener to add

getAccessibleChild

public Accessible getAccessibleChild(int i)

Returns the accessible child component at index i.

Parameters: i the index of the accessible child to return

public String getAccessibleName()

Returns the localized name for this object. Generally this should almost never return {@link Component#getName()} since that is not a localized name.
