Implement custom library browser / type hierarchy in an Eclipse plugin

Question

I'm creating an Eclipse Plugin for development using the Grammatical Framework (GF), and once of the major features I want to implement a custom "library browser" for searching the GF Resource Grammar Library (which will internally involve parsing a lot of header files manually). It would basically behave a lot like Eclipse's Java Type Hierarchy view, with my own implementation behind the scenes.

My question is, do you think the Common Navigator Framework (CNF) what I should be looking at? It seems suitable for my UI needs, but I thought I might ask just in case there's some other option I've overlooked.

Answer 1

Basically, the point of CNF is to make your tree-like view extensible: to allow several different bundles to provide items in the tree, actions on them, etc.

If the usual TreeViewer with a content and label provider is enough, there is no reason to go for CNF; if it isn't, do use CNF.
