Getting there, slowly... but a few more questions.

Firstly, the return of the function gtk_ctree_new() is GtkWidget* rather
than GtkCTree* - so do I have to get around this with typecasting?

Secondly, If I want to display the Ctree in a scrolled window, I would
try to use the function gtk_scrolled_window_add_with_viewport() but
again run into problems with type. Is this the right function to use? 

If I change the type of 'the_tree' then I can get everything to compile,
but can't get the ctree to be viewed.

Thanks,


Andy


PS When I've struggled my way through this then I will make the
resulting code available to anyone else having problems.
