The creation routine for the clist and ctree is very strict, and
the scroll bars are controlled greatly by the clist or ctree.

The proper way to have the horizontal scroll bar function properly
on a GtkCTree (not just a plain GtkCList) is to use:

gtk_ctree_set_line_style(ctree, GTK_CTREE_LINES_DOTTED);
gtk_clist_set_column_auto_resize(
        GTK_CLIST(ctree), 0, TRUE
);
gtk_clist_set_column_justification(
        GTK_CLIST(ctree), 0, GTK_JUSTIFY_LEFT
);

I'm assuming you only have one column in the GtkCTree btw.
If you have other regular columns in the ctree then it might
be a bit different but try the above anyways.
