Field Detail

ANCESTOR_ADDED

public static final int ANCESTOR_ADDED

Enabled: An ancestor-component was added to the hierarchy of visible objects (made visible), and is currently being displayed.

public static final int ANCESTOR_REMOVED

Enabled: An ancestor-component was removed from the hierarchy of visible objects (hidden) and is no longer being displayed.

Constructor Detail

AncestorEvent

public AncestorEvent(JComponent source,
                     int id,
                     Container ancestor,
                     Container ancestorParent)

Suppressed: Constructs an AncestorEvent object to identify a change in an ancestor-component's display-status.

Parameters:

source - the JComponent that originated the event (typically this)

id - an int specifying ANCESTOR_ADDED, ANCESTOR_REMOVED or ANCESTOR_MOVED

ancestor - a Container object specifying the ancestor-component whose display-status changed

ancestorParent - a Container object specifying the ancestor's parent

Method Detail

getAncestor

public Container getAncestor()

Suppressed: Returns the ancestor that the event actually occurred on.

getAncestorParent

public Container getAncestorParent()

Suppressed: Returns the parent of the ancestor the event actually occurred on. This is most interesting in an ANCESTOR_REMOVED event, as the ancestor may no longer be in the component hierarchy.

getComponent

public JComponent getComponent()

Suppressed: Returns the component that the listener was added to.
