Somehow I'm missing the beginning of this thread (at least by the current
subject).
Assuming you're using the 'namespaces' branch and use the TreeFullControl
class, there are events dispatched when a tree node is opened or closed.
There are in fact three events:
qx.constant.Event.TREEOPENWITHCONTENT
Dispatched when a tree folder is opened and already has children
qx.constant.Event.TREEOPENWHILEEMPTY
Dispatched when a tree folder is opened but has no children
qx.constant.Event.TREECLOSE
Dispatched when a tree folder is closed
These events are dispatched on the top-level Tree node.
The example demo/example/TreeFullControl.html shows how to use it.
AFAIK, there are no events dispatched in the Tree class in version 0.5.x nor
in the Tree class of 'namespaces'. This applies only to the TreeFullControl
class in 'namespaces'.

treeNode.getParentFolder() may be used to retrieve the parent node of the
requesting tree node.
