2005-06-13 Matthias Clasen <mclasen@redhat.com> Make invisible text work a bit better (#66194, patch by Jeroen Zwartepoorte) * gtk/gtk.symbols: * gtk/gtktextiter.[hc]: Add function to move by visible lines. * gtk/gtktextview.c (gtk_text_view_move_cursor_internal): Skip invisible text when moving by paragraphs. * gtk/gtktextlayout.c (gtk_text_layout_move_iter_visually): Skip invisible lines here too.
