title: How to attach data to TreeItem in SWT/Java?
body: <p>I'm starting to use the SWT GUI toolkit in Java. I have a need to attach some data to the TreeItems. Each toolkit I've previously used had a tree item, which contained a raw pointer or a base object reference to provide basic data containment, but I cannot find one in TreeItem in SWT.</p>
  
  <p>How can I attach data to the TreeItem?</p>
