* Since we require GLib-1.3, and thus can no longer build the examplesOwen Taylor2000-05-281-1/+1
| | | | | | | | | | | | | | | | Sun May 28 16:24:43 2000 Owen Taylor <otaylor@redhat.com> * examples/Makefile.am examples/viewer-qt.cc examples/viewer-qt.h: Since we require GLib-1.3, and thus can no longer build the examples against GTK+-1.2, and since there is a nasty circular dependency if we build examples against GTK+-1.3, rewrite (optional) example program in Qt. (I wasn't going to do it in Xaw or straight Xlib...) * configure.in: Added checks for Qt. * pango/pango-layout.h: Fix constness.
* New function for visual (left-right, not forward-back) cursor navigationOwen Taylor2000-04-241-16/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sun Apr 23 23:33:10 2000 Owen Taylor <otaylor@redhat.com> * pango/pango-layout.c (pango_layout_move_cursor_visually): New function for visual (left-right, not forward-back) cursor navigation within a layout. Thu Apr 20 22:16:39 2000 Owen Taylor <otaylor@redhat.com> * pango/pango-layout.c (pango_layout_line_x_to_index): As a hack, for x-positions at the edge of a line, fudge the position to be one before the line end (which is, for programs that don't properly handle the trailing flag), instead of at the end of the line. This works fine for whitespace-broken languages, but won't work right for languages that don't use whitespace to break lines. (GtkText* needs to keep track of whether a cursor is trailing or not) * pango/pango-layout.c (pango_layout_check_lines): Prohibit breaking a line at a non-whitespace -> space transition. (So that we never put wrap single character of whitespace at the beginning of a line) * pango/break.c (pango_break): Always allow a break before the first char. * pango/pango-layout.c (pango_layout_line_x_to_index): Remove the return value from the function, make it return the appropriate index depending on the base direction of the layoutt.
* Add a function pango_layout_line_get_x_ranges(), to allow handlingOwen Taylor2000-04-181-24/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mon Apr 17 12:04:20 2000 Owen Taylor <otaylor@redhat.com> * pango/pango-layout.[ch]: Add a function pango_layout_line_get_x_ranges(), to allow handling selections not as attributes. Which is necessary, since currently setting the background/foreground results in splitting shaped runs. Fri Apr 14 13:20:05 2000 Owen Taylor <otaylor@redhat.com> * pango/pango-layout.c (pango_layout_check_lines): Fix bug with indent handling. * pango/pango-layout.c (process_item): Never break a line at a non-break position, even if that position ends an item. Fri Apr 14 10:43:09 2000 Owen Taylor <otaylor@redhat.com> * pango/pangox.c (pango_x_render_layout_line): Fix a missing PANGO_SCALE factor for UNDERLINE_SINGLE. * pango/pango-layout.c (pango_layout_get_cursor_pos): New function to determine cursor positions corresponding to a particular index. Wed Apr 12 15:44:22 2000 Owen Taylor <otaylor@redhat.com> * pango/pango-attributes.[ch]: Add PANGO_ATTR_FONT_DESC, which allows an entire font description to be specified as a single attribute, instead of as 6 separate attributes.
* Add user data to PangoContextOwen Taylor2000-04-051-0/+2
| | | | | | | | | | | | | | | | | | Tue Apr 4 20:13:06 2000 Owen Taylor <otaylor@redhat.com> * pango/pango-context.h: Add user data to PangoContext * pango/pangox.[ch] examples/viewer.c: Rework system for create GC's so that the necessary information is stored on the PangoContext instead of being passed to layout_render() * pango/utils.[ch] pango/pango-context.c: fribidi-0.1.9 wants UCS-4 not UCS2; switch accordingly. * pango/fonts.c pango/pango-font.h pango/pangox.c: Add functions to get overall font metrics, possibly per-language. (Right now, just font ascent, descent.) The implementation of this for X is horribly complex.
* Use "UTF-8" with the dash as the charset name for utf-8. (Change suggestedOwen Taylor2000-03-301-0/+4
| | | | | | | | | | | Thu Mar 30 16:49:06 2000 Owen Taylor <otaylor@redhat.com> * modules/basic/basic.c pango/utils.c (find_converter): Use "UTF-8" with the dash as the charset name for utf-8. (Change suggested by Adrian Havill <havill@turbolinux.co.jp>) * pango/pango-layout.[ch]: Add function to get logical attributes of the text string.

Use this to handle underlining for PangoLayout. * examples/viewer.c (reload_font): Make paragraphs global to save the complexity of passing it around all over the place. * pango/pango-layout.[ch] (pango_layout_context_changed): Add a function to reset the layout on changes to the layout's context. * pango/pangox.c (pango_x_make_matching_xlfd): Prefer bitmap to scaleable if the discrepancy is < 1 pixel. (Probably not the ideal criterion.) * pango/pangox.c (pango_x_font_map_for_display): Fix resolution computation error. * pango/pango-layout.c (pango_layout_check_lines): Handle text with embedded newlines. * pango/pangox.c (pango_x_render_layout): Fix y to refer to the top of the layout, not the baseline of the first line. * pango/pango-layout.c (process_item): Don't wrap if width is set to -1. * Makefile.am configure.in **/*.[ch]: move libpango/ directory and fix all headers to install under include/pango/
* Release pango-0.8Owen Taylor2000-03-101-23/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | Thu Mar 9 19:55:21 2000 Owen Taylor <otaylor@redhat.com> * Release pango-0.8 * docs/TEXT/coding-style: Added some notes about coding style within Pango. * modules/*.[ch]: New version from Karl Koehler adding support for vowels marks, better ligatures. * docs/tmpl/*: Doc updates * libpango/pango-layout.[ch] libpango/pangox/.[ch]: Add functions for handling paragraphs as 2-D objects, not simple lists of lines, to make things easier for people using pango-layout. * examples/viewer.c: Simplify using the now 2-D layout-capabable PangoLayout. * libpango/fonts.c (pango_font_{get_coverage,find_shaper}): Allow NULL language tag. * libpango/modules.c (_pango_find_map): Fix for allowing NULL language tag.
* First draft of highlevel driver. It currently only handles a paragraph asOwen Taylor2000-03-081-31/+40

It currently only handles a paragraph as a list of lines, but it is probably necessary to make it handle 2D layout for a paragraph as well * examples/viewer.c: Move over to new layout driver (much of the code moved into pango-layout.c) * libpango/glyphs.c libpango/pango-glyphs.h: Fixes to get_extents(), add pango_glyph_string_get_logical_widths. * libpango/pango-itemize.c: Handle 0-length text properly. * libpango/pangox.c: When loading particular sized fonts, use the original XLFD, since XFree86 doesn't handle wildcards in aliases properly. * libpango/pangox.[ch] (pango_x_render_layout_line): Add function to render an entire PangoLayoutLine. * libpango/reorder-items.c: Add a note to the effect that pango_reorder_items() is basically replaced by a similar function in PangoLayout. Wed Mar 8 10:58:56 2000 Owen Taylor <otaylor@redhat.com> * modules/arabic/arconv.c (shapecount): Fix from Karl Koehler to joining behavior. * modules/Makefile.am modules/arabic/*: Added arabic shaper from Karl Koehler <koehler@or.uni-bonn.de> * modules/basic/tables-{small,big}.i: Remove arabic from the ranges that the basic shaper marks as "exact". * examples/HELLO.utf8: Partially alphabetize, add arabic.

(We may want to fastpath the width in the future, since getting the width seems to be a very common and time-critical operation)
* The great header file reorganization. Split up roughtly by objects.Owen Taylor2000-02-011-0/+44
Wed Feb 2 00:07:13 2000 Owen Taylor <otaylor@redhat.com> * libpango/pango-*.h: The great header file reorganization. Split up roughtly by objects. * libpango/pango-font.h libpango/fonts.h: Add generic font-loading and listing interfaces. * libpango/pangox.c: Implement font-listing/loading interfaces for X. * libpango/pango-context.[ch]: Flesh out context structure. Add appropriate accesors, font loading-methods, etc. * libpango/pango-coverage.[ch]: Coverage map objects. * examples/viewer.c: First stab at adding font-selection. Majorly deficient for the moment until we add font lists and fallbacks based on coverage maps.
