The JToggleButton Class
JToggleButton is an extension of AbstractButton and is used to represent
buttons that can be toggled on and off (as opposed to buttons like
JButton which, when pushed, “pop back
up”). It should be noted that while the subclasses of JToggleButton (JCheckBox and JRadioButton) are the kinds of JToggleButtons most commonly used, JToggleButton is not an abstract class. When
used directly, it typically (though this is ultimately up to the
L&F) has the appearance of a JButton that does not pop back up when pressed
(see Figure 5-6).

Properties
The JToggleButton class
inherits all of its properties and most of its default values from its
superclass. The exceptions are shown in Table 5-10. The model property is set to a new instance of
ToggleButtonModel when a JToggleButton is created. ToggleButtonModel (described in the next
section) is a public inner class that extends DefaultButtonModel.

Events
Like JButton, JToggleButton defines no new events. However, the events fired by
JToggleButtons are slightly
different than those fired by
