Don't you have to use

Gtk::Box_Helpers::BoxList::iterator i;
    
for the i declaraction?
And, from what I see in <gtk--/box.h>, *i is not a pointer, but a
reference to an object of class Gtk::Box_Helpers::Child, so you should not
try to delete it.

How about

i = blist.begin();
i++;    /* Skip combo/button box */
blist.erase(i, blist.end());

for the rest? If all your contained widgets are managed, I think it should
work.
