15.9.ChangeListener
	15.9.1.	Listening to JMenu Events with a ChangeListener: register a ChangeListener with a JMenu
	15.9.2.	Registers a change listener on a slider that controls animation speed. The change listener ignores the change events until the user releases the slider.
	15.9.3.	Uses a change listener on the selection model of a color chooser to learn when the user changes the current color.
	15.9.4.	Uses a change listener on a date-field spinner to change the color of the text as the spinner's date changes.
	15.9.5.	Tab change listener
	15.9.6.	Get value of BoundedRangeModel in its change listener
