Adds a PropertyChangeListener to the listener list for a specific
property. The specified property may be user-defined, or one of the
following:

* this Component's font ("font")
* this Component's background color ("background")
* this Component's foreground color ("foreground")
* this Component's focusability ("focusable")
* this Component's focus traversal keys enabled state
("focusTraversalKeysEnabled")
* this Component's Set of FORWARD_TRAVERSAL_KEYS
("forwardFocusTraversalKeys")
* this Component's Set of BACKWARD_TRAVERSAL_KEYS
("backwardFocusTraversalKeys")
* this Component's Set of UP_CYCLE_TRAVERSAL_KEYS
("upCycleFocusTraversalKeys")

Note that if this Component is inheriting a bound property, then no
event will be fired in response to a change in the inherited property.

Try call typeChoice.setForeground() from other GUI event handler.
