Re: [Gtk2hs-users] [Gtk2hs-devel] Documentation and implementation of treeStoreInsertForest disagree

[Axel S. <Axe...@in...>]

If I'm not mistaken, the docu is of a newer version and the type is from some older Gtk version where the C function actually did not return the insertion function but void. I think it depends on the oldest Gtk version, we want to support.
