update to reflect text widget changes.

Browse Source 
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

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
2000-07-25 Havoc Pennington <hp@redhat.com>
* gtk/gtkprogressbar.h: Implement new sane, 5-function API for
