Changing the pop-up icon is one example of customizing the look and feel. To do this,
you'll need to install a new user interface. (This process is discussed at length in Chapter 20.)
Basically, you inherit the default functionality from either the
BasicComboBoxUI
or
MetalComboBoxUI
user interface delegate, and then override only the
protected JButton createArrowButton()
method.
Figure 13-20 shows the results of this change to the
JComboBox
user interface.
