filesystem tree familiar to many PC users, the
JTree
allows you to view multi-
ple levels at once and to open and close nodes, exposing or hiding their subtrees.
It would make more sense to use the
JTree
in our example, but then we
wouldn't have been able to describe all the ins and outs of the
JTable
, a class
that is so useful in so many applications.
There are many more Swing classes that we haven't discussed, though
many will behave similarly to those you have seen here. There are topics that
we have avoided—for example, we haven't talked about sorting
JTable
s by
clicking on the column headings, or about
TableColumnModel
s which add
another layer to
JTable
s. Some of what you would need to know in order to
use these Swing classes you can glean from the Javadoc pages. The information
there should make more sense now, based on your experience with the various
Swing mechanisms that you've seen in these pages. For some other Swing topics
you will have to search farther, and there are plenty of topics on the topic—the
classic one, the
The JFC Swing Tutorial
from Sun, being over 900 pages long.
Is it any wonder that we didn't cover it all in this chapter?

. Don't let the mention of AWT scare you away. Almost
all of the layout managers (except
BoxLayout
and
SpringLayout
) are
actually from AWT, and they all apply to Swing.
