These are those parts of Komponenten's main library which are of interest to a wider user group. This library contains: - SimpleTree: a widget which interactively transforms a linear list into a tree and displays it - more Model/View/Controller like Widgets for gtkmm2 and perhaps more. I apologize for not documenting them up to now and (of course) these classes have a long history so they sometimes start to smell ... Use them, improve them, share them. Jacek, Malte & Christof
