2000-12-04 Havoc Pennington <hp@redhat.com> * gtk/gtkpaned.c (gtk_paned_expose): fix this to be sane * gtk/gtkvpaned.c (gtk_vpaned_expose): Add an expose handler * gtk/gtkhpaned.c (gtk_hpaned_expose): Add an expose handler * gtk/gtknotebook.c (gtk_notebook_draw_tab): put in a temporary hack to avoid infinite loops (queue draw instead of draw) - Owen has more appropriate fixes in a branch he'll check in later. * gtk/gtktextiter.c (gtk_text_iter_ends_line): handle paragraph separator, CR, and CRLF as line ends * gtk/gtktextbtree.c (gtk_text_btree_insert): on insertion, break into lines using pango_find_paragraph_boundary(); other bits of the widget are still going to be broken if the boundary isn't '\n' though
