Errata

In the SiteManager example code, there is a small error..

You add a ListSelectionListener to the nameList. In this function, you need to check whether the
selection is in progress or is finished. The way it is written causes the selected PageFrame to
be displayed twice.

To fix it, you need only add one conditional statement:

nameList.addListSelectionListener (new ListSelectionListener () {
public void valueChanged (ListSelectionEvent lse) {

// Add this conditional statement:
if (!lse.getValueIsAdjusting ()) {
parent.addPageFrame ((String)nameList.getSelectedValue ());
}// end if
} // end valueChanged ()
});

This will ensure that the page is only displayed once upon selection.

From the book:

"Swing currently provides several styles of borders, including an empty border. Each
one extends the javax.swing.border.Border interface."

The word "extends" should be "implements." Technically, it is the AbstractBorder
class that implements the Border interface, with the concrete border classes, such as
EmptyBorder, extending the AbstractBorder class.

The sample in the book tries to load sample icons 1.gif .. 6.gif, that are not
included with the downloadable samples. Editing the IconSpinner.java file, replace
these with something like

Icon nums[] = new Icon[] {
new ImageIcon("covers/ant.gif"),
new ImageIcon("covers/java2d.gif"),
new ImageIcon("covers/jdbc.gif"),
new ImageIcon("covers/jcook.gif"),
new ImageIcon("covers/jsoap.gif"),
new ImageIcon("covers/swing.gif")
};

While Table 11-17 suggests that the Spring class has the properties maximum, minimum and
preferred, it has in fact the properties maximumValue, minimumValue and preferredValue.

While text states that the nodesWereRemoved() method has the signature

public void nodesWereRemoved(TreeNode node, int childIndices[])

the correct signature according to the Java API 1.5.0 is in fact

public void nodesWereRemoved(TreeNode node, int childIndices[], Object[] removedChildren)

Both Table 24-16 and the text suggest that cursor is a read-only property of the
DragSourceContext class. However, at least for Java 5 and 6 (I didn't check for earlier
versions), there does in fact exist a setCursor() method for setting it.

In Java 5 and 6 (I didn't check for earlier versions), the DragSourceEvent class has also a
location property (and respective getLocation(), getX() and getY() methods), which is mentioned
neither in the text nor in Table 24-18.
