How would I do this using GtkBuilder? As far as I can see 
gtk_builder_add_from_file doesnt support a similar argument.

Using gtk_builder_get_object (builder, "mainvbox"))  doesnt stop parent 
widgets being obtained as well.

The mainvbox is in a window in Glade because you have to put it in one, 
but when I read the file into my program I already have a window for it 
to go in, I only need the vbox.

Just doing

gtk_builder_add_from_file (builder, "./gladexml/general.xml", NULL);
        generalpage= GTK_WIDGET (gtk_builder_get_object (builder, 
"mainvbox"));

then

gtk_scrolled_window_add_with_viewport(GTK_SCROLLED_WINDOW(rightpanescrollview),GTK_WIDGET(generalpage));

is giving the error:
 Gtk-CRITICAL **: gtk_scrolled_window_add_with_viewport: assertion 
`child->parent == NULL' failed
