2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function
