converting Swing JTree to SWT Tree [message #461431]

I'm currently converting a software project from Swing to SWT and run into
problems by trying to replace parts of Swing's JTree. It looks like Swing
makes use of a DefaultMutableTreeNode, e.g. for the root node, which is not
given in SWT. Has anybody an idea how I can get rid of that (workaround?)
and if there is a way to address the root node of a Tree in SWT?

I think I got the solution for that (I worked with an old SWT API :-(). SWT
provides TreeItems instead of DefaultMutableTreeNodes and further more the
option to set the rootNode by using the setTopItem() function:

Tree tree = new Tree(this, SWT.SINGLE | SWT.BORDER);
rootNode = new TreeItem(tree, SWT.NULL);
rootNode.setText("Root");
tree.setTopItem(rootNode);

One question still remains open besides that but concerning Trees. Is it
right to remove a TreeItem by using the dispose() method? Because I can't
find any method like removeItem(int index) or something like that.
