2000-12-14 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (_gtk_text_btree_validate_line): remove unused call to get_last_line() * gtk/gtkobject.c (gtk_object_add_arg_type): add G_TYPE_POINTER here until boxed is working (and maybe after that - we should really not gratuitously break old code) * gtk/gtktexttag.c (gtk_text_tag_class_init): add commented-out specific types for font_desc and tabs args, move them to GTK_TYPE_POINTER for now, waiting on g_param_spec_boxed() to get fixed. Move GdkColor args to GTK_TYPE_POINTER also. * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): temporarily use GTK_TYPE_POINTER for signal signatures as a hack-around * gtk/gtk-boxed.defs: Add boxed types for PangoFontDescription and PangoTabArray * gtk/gtktextlayout.c (line_display_iter_to_index): make static (line_display_index_to_iter): make static * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): fix marshaller to marshal a string not a boxed * gtk/gtkmarshal.list: add marshaller for GtkTextBuffer:insert_text * gtk/testtext.c (fill_file_buffer): don't use g_utf8_next_char since the UTF-8 isn't validated yet * gtk/gtktextsegment.c (char_segment_check_func): don't require lines to end in '\n' * gtk/gtktextview.c (gtk_text_view_move_cursor): update to use forward_to_delimiters, and grapheme boundaries (gtk_text_view_delete_from_cursor): properly handle non-newline delimiters, and grapheme boundaries * gtk/gtktextiter.c (gtk_text_iter_forward_to_newline): rename to gtk_text_iter_forward_to_delimiters, and make it work properly if empty lines end with a character other than '\n' * gtk/gtktextiter.h, gtk/gtktextiter.c: Add movement by cursor position
