Perhaps you could custom draw a separator line across the top of your
second root-level item. For info on using custom draw in Tables and

Thank you for your advice. I use one of the snippets in the link to solve my other problem About the separator problem, I settle with the naive method above.
Hm, usually trees don't contain separators. Hence there is no direct way to do it. I'd try to avoid it or use your suggested naive way.
I wish I wouldn't have to use separator but using separator seems to be the easiest way to solve my problem.
Moreover, I don't know if I understand the Viewer framework exactly. This is an image I think that describes the framework :http: //i.imgur.com/wx1je.png. In my understanding, when we setInput on an object for a Tree, this object is feeded to the ContentProvider. The elements come out from the ContentProvider will be filtered by various filters. After that, the remaining elements will be sorted. Finally, the tree widget will take these elements and display them. Is it correct ?
