HACK

If you wanted to hack further, you could make this and other small func-

tions like it each separate decorators. Then you could combine them at will,

depending on the needs of your application.

Wrapping Up

This table model decorator is now part of the main Lucene distribution. It’s

part of a new lucene-contrib project for Swing. In addition to this table

model decorator, there is also a list decorator. I imagine the search logic is

going to beef up, so definitely check out the Lucene site for more informa-

tion. You can get read-only web access to the Lucene repository at http://svn.

apache.org/repos/asf/lucene/java/trunk/contrib/swing/. Also note that because

these models are officially part of lucene-contrib, they are going to be distrib-

uted with all new Lucene builds. So, they are going to come free with

Lucene in the future.

Animate JTree Drops Hack #27

Who said working with tree paths was hard? Now you can reorganize tree

hierarchies with drag-and-drop.

JTrees are great for representing hierarchy, but they’re not so hot as control

widgets. You might want to drag items inside a tree, or accept a drop from

some other part of your application, and it turns out not to be well suited to

that. The problem is that the

JTree isn’t really a container, so from the

Swing programmer’s point of view, you see the tree’s
