34 *
35 * This class is only used for gtk(mm) <= 2. If application is compiled against
36 * gtk(mm) >= 3 then this class is not compiled at all. gtk(mm) 3 added support
37 * for automatic multi-line labels by calling its set_line_wrap() method.
38 * However Gtk::Label may still cause size calculation problems under certain
39 * conditions. If you encountered such a problem, then use @c MultiLineLabel for
40 * for gtk(mm) >= 3 instead.
