The problem is the same for every "scrollable" widget
which can be added to a scrolled_window. E.g. CList only
returns the border size too, as long as CLists
scroll_adjustments are != NULL. If you call
gtk_clist_set_hadjustment(clist, NULL) clist will
answer size requests with its exact width.
I like that behavior, because it works without
scrolled_windows and its policies. If you don't want
to scroll a CList in one direction, don't add an adjustment.
So a GTK_POLICY_NEVER would be very straight forward :
gtk_widget_scroll_adjustments (widget, NULL, NULL);
