tree model complaints

[D M <isaac belial pl eu org>]

        Hi.

        I'm implementing a custom tree model in my application. And one
thing itrigues me a little - why does it involve implementing 
a functions which are complementary - getting n'th child is kind
of equivalent of getting first child and then iterating 
over consecutive elements. Moreover - path conversion does'nt
make life easier - why is that? I have taken a look at Java's API
and there it is much simpler and starighforward.
