I'm using Tree object in my SWT application.
I dynamically insert TreeItem objects as my application generates them
(work fine).
I need to also be able to delete nodes (TreeItem) dynamically.
I don't see anything in the Tree or a TreeItem that allows me to delete
a node.
The best that I can find is Tree's 'removeAll()' method which implies
that to delete a node I have to:
- get all the existing nodes into a collection,
- remove all the nodes from the Tree,
- remove the selected node from the collection,
- re-insert all the nodes back into the Tree.
This is a draconian solution which doesn't scale up properly when there
are many nodes in the Tree.
-TIA

You can use TreeItem.dispose() to get rid of individual nodes.

It worked... thanks.
Its such a 'well documented' side effect of 'dispose' that I would never
have found it! ;-)
