[cp-patches] FYI: expand/collapse for JTree

[Lillian Angel]

I committed a minor fix for my last patch.

2005-07-06  Lillian Angel  <address@hidden>

        * javax/swing/plaf/basic/BasicTreeUI.java
        (getNextVisibleNode): Implemented
        (getPathForRow): Fixed so the next node retrieved is visible.
