1st paragraph

Rectangle r = new Rectangle( ); r = frame.getBounds(r); System.out.println("X = " + r.x( )); System.out.println("Y = " + r.y( )); System.out.println("Width = " + r.width( )); System.out.println("Height = " + r.height( )); I found this topic 3.5.6 Position, Size, and Alignment talk about the propertys,and I read http://java.sun.com/javase/6/docs/api/java/awt/Rectangle.html. The Rectangle class has the fields: Field Summary int height The height of the Rectangle. int width The width of the Rectangle. int x The X coordinate of the upper-left corner of the Rectangle. int y The Y coordinate of the upper-left corner of the Rectangle. so We need to change the code to : Rectangle r = new Rectangle( ); r = frame.getBounds(r); System.out.println("X = " + r.x); System.out.println("Y = " + r.y); System.out.println("Width = " + r.width); System.out.println("Height = " + r.height);

Note from the Author or Editor:
This is correct. It looks like the author of this page couldn't decide whether to use the properties, or the public fields (yuck) in the Rectangle object. The code should be either as the reader shows (removal of the parentheses from the field accesses), or it should use getX(), getY(), getWidth() and getHeight(). I would vote for the latter.

Note from the Author or Editor:
The reader is correct; the line should be as they specified in their erratum. Thanks for catching that.

Table 7-2

Table 7-2 lists the property elementAt as an indexed property with a bullet under the "set" column. Although there is a setElementAt(Object obj, int index) method on DefaultListModel, this is not the signature of a setter for an indexed property and you cannot use reflection on elementAt with an indexed write method. The bullet under the set column should be removed for elementAt. It seems other tables correctly show this situation such as Table 7-12, page 196, as an example. AUTHOR: The reader is correct. The proper method signature would be setElementAt(int, Object). The bullet should be removed, although I would note in the errata that both of the following methods are available for setting the value of a particular element: public void setElementAt(Object elem, int index); public void set(int index, Object elem); We probably should have footnoted that fact...

GlassExample.java

There is an updated version of the GlassExample available at - http://examples.oreilly.com/9780596004088/code/ch08/newglass.zip This fixes two bugs: 1) Key events were not supressed in the original example, they are now 2) On 1.2 and 1.3 systems, first mouse click after removing glass pane would not be sent to the component under the mouse. This was a bug in the way JRootPane handled the glass pane component that has been fixed in the 1.4 release. FixedGlassPane.java (see below) provides a workaround for 1.2 and 1.3, but is still safe to use with 1.4. The updated files are: GlassExample.java Updated to use (and control) the new glass pane FixedGlassPane.java Extension of JPanel that allows for redispatching erroneous events to their rightful owners

"The toggleClickCount property allows you to specify how many clicks are required to start editing a tree node." should read: "The toggleClickCount property allows you to specify how many clicks trigger an action on a tree node. If that node is a leaf and the tree is editable, it will start the editing process. For non-leaf nodes (folders), the appropriate number of clicks will expand or collapse the node."

Text reads "Don't worry too much about the TransferableTreeNode class (we discuss this in greater detail in the next section)." The class is never described or defined in the "next section" or the rest or the chapter (or in any other), and can only be found on the website. AUTHOR: True. The code is online, but the discussion of it is indeed missing from the book. An explanation should be included in future reprints/editions of this book.

3rd paragraph

With J2SE SDK 1.4, the MacMetrics jar file contains classes that were compiled in the default package. As such, they will only work with your application if it, too, resides in the default package. Regrettably, we have neither the source nor the permission to alter the jar file. A simple launching application written as part of the default package however, should be able to bootstrap larger applications during development.
