A corner case in JTree behaviour:
One of my test applications does the following to ensure that the
tree node selected by the user becomes visible:
...
TreePath treepath = new TreePath( node.getPath() );
fileListTree.setSelectionPath( treepath );
fileListTree.scrollPathToVisible( treepath );
fileListTree.expandPath( treepath ); // FIXME: required?
When the selected subtree has more leaf nodes than fit on screen,
classpath (cvs 2006.10.19) scrolls the tree to show the path from
root-node to selected subtree, but the currently selected leaf node
might become invisible. The JDK scrolls the tree to always show the
selected leaf node, which is better.
Note that the above code might be questionable, because the call to
expandPath() after scrollPathToVisible() is redundant. I probably
added it to get an earlier version of classpath or the JDK (1.3.x?)
to work...
