[Bug swing/28061] New: JTree issues and regressions

[hendrich at informatik dot uni-hamburg dot de]

At the moment, the state of JTree is much worse than some time ago...
Run the free swing demo and select "tree demo".


1. clicking on the "switches" does nothing. It should expand/collapse the
   corresponding subtree.

2. double-clicking an intermediate node correctly expands its subtree,
   but double-clicking again does not collapse the subtree. As a result 
   of 1. and 2., we can never collapse a subtree again.

3. clicking the text label a node correctly selects that node, but double-
   clicking the label of an node does nothing. The reference implementation
   expands/collapses the subtree of an intermediate node (and users will
   expect this).

4. The JTree ignores the cursor-key navigation: cursor-up and -down should
   move one node up and down, cursor-right and cursor-left on an intermediate
   node should expand/collapse the subtree. This was working sometime ago.

5. doesn't look that nice (switches just ugly, a little too much spacing).

6. scrollPathToVisible( treepath ) does not work.

I also attach the first version of a class, whose more polished version
might make it into the free swing demo later on... JTree on the left,
with lots of nodes in it (repainting slow because of the JTextArea).
