The JRadioButton that you see in the JTree is nothing more than a "picture"
of a JRadioButton. The tree's cell renderer passes a JRadioButton to the UI,
which then takes a snapshot picture, and draws it in the tree. There is no
component to receive those events.

You have to add a mouse listener to the JTree. In this mouse listener, you
will determine which row is being affected, update the node at that row, and
trigger a redraw of the tree. You may want to get on devx.com and search the
Java Pro archives for an article by James Cooper (Javatecture Column). The
article has the words "Forest" and "Trees" in the title. It showed how to
enable checkboxes in a tree. Most of the advanced Swing books also have
these examples.
