I have a TreeViewer, whose label provider supplies a folder icon for the
folder nodes being displayed in the tree.
We have a requirement that when the folder node is expanded, the icon
against it must change to an expanded folder icon. I could not find how
I can make the label provider do this. There is no hook I could find to
trigger the label provider to provide an updated icon. I do not want to
refresh the node - just need the icon to be updated on expand.
Is there any way to accomplish this?
I am using Eclipse 3.5, but may need this for 3.2 and 3.3 (on which our
product is supported as well).
