You should generally be working with content and label providers, not
directly with tree items. In the later case your question is an SWT
question, not a JFace question. JFace manages the underlying widgets
for you via the providers so you should only operate on the model level
and content/label provider level. I.e., you'd tell the viewer that some
object's label is changed and ensure that the label provider returns the
appropriate new image when asked for the image.
