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.
