[gnumeric.git] / OChangeLog-1999-07-09

1999-07-09  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/about.c (dialog_about): Sort in alphabetical order.

        * src/print-info.c (print_hf_free): Killed the style_format feature.

        * src/print.c (print_job_info_get): Create render info context
        here for header/footer printing.
        (print_sheet_range): Setup number of pages here;  Increment pages
        after each one is outputed.
        (print_headers): Implemented the header/footer printing.

        * src/print-info.c (hf_render_info_new, hf_render_info_destroy):
        New routines.

        * src/fn-date.c (gnumeric_return_current_time): New function.

1999-07-09  Miguel de Icaza  <miguel@gnu.org>

        * configure.in (GNOMEGNORBA_LIBS): Simplified the Bonobo detection code.

1999-07-09  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/analysis-tools.c: Changed prototype of int_compare to
        eliminate a warning.

        Removed unused variables.

        * src/cell.c: #inlcude gnumeric-util to eliminate warning.

        * src/fn-financial.c: Fixed all the help strings to get the
        SEELASO correctly done

        * src/style.c: Zoom factor 1.0 is a reminder to me, not a warning.

1999-07-09  Miguel de Icaza  <miguel@gnu.org>

        * src/sheet-view.c (sheet_view_construct): Reverted last plan.  We
        do need a sheet_view_construct, as we require sheet_view->sheet to
        be set.

1999-07-08  Miguel de Icaza  <miguel@gnu.org>

        * src/cell.c (calc_text_dimensions): Use gdk_fonts for measuring
        the strings on the screen.  Basically, back out using GnomeFont here.

        * src/print-info.c (render_date, render_time): Finished
        implementing.
        (render_opcode): Enable argument mechanism to extend the number of
        possible formats.  Excel accepts stuff like &[DATE], we extend
        this to accept &[DATE:mmmm-yyyy].  The argument for &[DATE] and
        &[TIME] is a regular Gnumeric formatting code (ie, compattible
        with the cell formating in Excel).

        * src/sheet-view.h: Change style to suit forward declaration
        structure.

        * src/sheet.h: Use forward declaration for SheetView.

        * src/sheet.c (sheet_new_sheet_view, sheet_destroy_sheet_view):
        New routines for managing the sheet views.

        * src/sheet-view.c: Killed sheet_view_construct, there was nothing
        really required there.  Moved all the code to sheet_view_init.
        (sheet_view_scrollbar_display, sheet_view_set_header_visibility):
        New routines that control the visibility of the various gadgets of
        a SheetView.

        * embeddable-grid.c, embeddable-grid.h: New files.  They implement
        the Bonobo GnomeEmbeddable interfaces for embedding Gnumeric in
        applications.

        * src/workbook.c (workbook_new, workbook_core_new): Split this
        routine in two:  GUI independant and GUI dependant.  The next step
        is to provide multiple views of a workbook (although, I am not
        sure I want this).
        (workbook_new_with_sheets): Kill dead code.

        * src/corba-sheet.c (Sheet_row_height, Sheet_col_width,
        Sheet_max_cols_used, Sheet_max_rows_used): New methods.

        * src/Gnumeric.idl (Sheet): new methods max_cols_used,
        max_rows_used, col_width, row_height.

        (Grid): New interface for embeddable grids.

        * src/print-info.c (hf_format_render): Rendering routine for the
        header and footers formats.

1999-07-09  Michael Meeks  <michael@edenproject.org>

        * src/Gnumeric.idl: Add GNOME::Unknown back in.

        option to all tools to print the results to a new workbook.

        * src/dialog-analysis-tools.c, src/analysis-tools.c: Added Moving
        Average and Rank and Percentile tools.

1999-07-09  Michael Meeks  <michael@edenproject.org>

        * src/eval.c (add_value_deps): Add warning on default:
        (add_cell_range_deps): Fixup for correct inter-sheet
        dependencies; massive bug.

        * TODO: Updated.

        * doc/C/formulas.sgml: Wrote the 'name' documentation.

1999-07-08  Michael Meeks  <michael@edenproject.org>

        * src/func.c (function_iterate_do_value): Fix for NULL CellRef
        Sheet *, fallback to EvalPosition's Sheet *

        * src/cell-draw.c (cell_split_text) : Honour embedded newlines.
          Why do we call str_trim_spaces ?

        * src/print-cell.c (cell_split_text) : Ditto.  Adjust gnome-print to
          make the code even more similar to cell-draw version.  Should we be
          using double rather than int for width calculations ?
          NOTE : This requires some recent (1999/7/7) changes to gnome-print.

        * src/cell.c (cell_comment_realize) : reference the comment object
          to avoid verbose warnings when we exit.

1999-07-08  Jukka-Pekka Iivonen  <iivonen@iki.fi>

        * doc/C/analysis-tools.sgml: New file. Added documentation for the

        Statistics, Random Number Generation, Sampling, and F-Test.

        * src/dialog-analysis-tools.c: Added some default parameters for
        the random number generation tool.

        * src/dialog-analysis-tools.c, src/analysis-tools.c: Started the
        implementation of regression tool.  Feel free to fill in the rest
        of the calculations if you are familiar with the regression

        * samples/engfuns.xls, samples/mathfuns.xls: Updated.

1999-06-29  Jukka-Pekka Iivonen  <iivonen@iki.fi>

        * src/fn-stat.c: Added FORECAST() and INTERCEPT().

        * src/fn-math.c: SUMIF() can now take an optional argument
        (actual_range).

        * src/fn-information.c: Made N() return 0 if the given string is
        non-number, not an error.

1999-06-28  Michael Meeks  <michael@edenproject.org>

        * src/main.c (gnumeric_main): removed xbase_init.

        * src/Makefile.am: Removed xbase static link.

1999-06-28  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/dialog-printer-setup.c (load_image): Use a constant relative
        to the Gnumeric installation directory, do not use the gnome
        pixmap path routine.

1999-06-28  Michael Meeks  <michael@edenproject.org>

        * CHANGES: Updated for new release.

1999-06-27  Raja R Harinath  <harinath@cs.umn.edu>

        * src/Makefile.am (Gnumeric-impl.o): This depends on Gnumeric.h,
        Gnumeric-impl.c doesn't.

        Reinstate Perl plugin.
        * plugins/perl/Makefile.am: Clean up build.
        * plugins/perl/ext/Gnumeric.xs (register_function):
        Use FunctionCategory and `function_add_args' API instead of
        `install_symbol'.
        (marshal_func): Update to new callback prototype.
        * plugins/perl/ext/Makefile.PL.in ('INC'): Use @top_srcdir@ rather
        than @srcdir@/../../...

        * doc/C/Makefile.am: Misc. srcdir != builddir fixes.
        * configure.in (GNOME_PRINT_CFLAGS): Fix typo.

1999-06-25  Michael Meeks  <michael@edenproject.org>

        * src/dialog-function-wizard.c: Re-vamped table layout.

        * src/fn-string.c (string_functions_init): Change category
        name to 'String'; silly me.

        * src/dialog-function-select.c (function_definition_update): Fixed
        old & broken function pointer code.

        * src/expr.c (eval_funcall): Updated to use union.
        (function_def_call_with_values): ditto.

        * src/func.c (function_add_nodes): ditto.
        (function_add_args): ditto.

        * src/expr.h: Changed void *fn pointer to a slicker union.

        * src/plugin.h: Added a prototype for the one external function
        every plugin must have ( kills some plugins warnings ).

        * src/workbook.c (workbook_new): Updated call to set_auto_expr
        (change_auto_expr): ditto.
        (workbook_do_destroy): Update.
        (workbook_set_auto_expr): Updated, just to set text leaving heavy
        lifting for sheet.c. This removes possible error checking of our
        quick-functions, but an error will be displayed in the status bar
        having set the function, and the functionality wasn't used.

        * src/sheet.h: Removed previously extern'd workbook_set_auto_expr,
        this should be internal.
        Remove auto_expr_tree from Workbook *.

        * src/sheet.c (sheet_update_auto_expr): Moved auto_expr parsing
        into sheet_update_auto_expr. Rational; neater, and not performance
        critical.

1999-06-26  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/pixmaps.h: Removed unused pixmaps.

        * src/corba-sheet.c (Sheet_corba_class_init): Fill in some missing
        values fomr the GNOME::Gnumeric::Sheet epv interface.

        * src/expr.c (eval_funcall): Removed unused variable.

        * src/workbook.c (workbook_sheets): prepend and reverse instead of
        appending all the time.  It is more efficient.

        * src/style.c (x11_font_compute_hints): Renamed as well.  Might be
        useful in the future.

        * src/gnumeric-util.c (x11_font_get_italic_name,
        x11_font_get_bold_name, x11_font_change_component): Renamed these
        functions to reflect their actual usage.

        * src/expr.c (expr_tree_new_constant): Change style to use early
        return to keep indentation of the rest of the code at tab-1.  This
        is a trick to keep indentation nice with 8-tab spaces.  Liberal
        use of early returns, early continues, early breaks.

        * src/cell.h (CELL_TEXT_GET): Kill unused macro.

1999-06-25  Miguel de Icaza  <miguel@gnu.org>

        * src/xml-io.c (xml_read_cell): Merge the style we just read with
        the existing information from the cell (which are the defaults).
        This is only for compatibility with the old format

1999-06-24  Miguel de Icaza  <miguel@gnu.org>

        * src/xml-io.c (style_font_new_from_x11): Implemented

        * src/style.c (style_font_new): Improved matching of the font.

        * src/xml-io.c  (xml_write_style): Save Bold and Italic
        properties.  Save Units as double.
        (xml_read_style): Add conversion hook from old format.
        (xml_read_style): Load properly italic and bold properties.

        (xml_read_cell): Add new style reading code.  It is
        compatible with the old Style reading code.
        (xml_read_rows_info, xml_read_cols_info, xml_read_styles): Moved
        Cols, Rows and Styles loading code here, for code clarity.

        * src/style.c (style_font_new_simple): Include the scale in the
        key lookup variable.

        * src/xml-io.c: The FontDefs and the HREFs to the fonts were never
        being used.  The new code for styles simplifies this.  Kill all
        the references to the FontDefs urls and the font indeces.

        * src/xml-io.c

1999-06-23  Miguel de Icaza  <miguel@gnu.org>

        * src/xml-io.c: Major updates.
        (xml_read_colrow_info): Use floating point for loading the
        units, margin_a and margin_b.
        (xml_write_colrow_info): Save units, margin_a and margin_b using
        floating point.
        (xml_set_value_double): Activate this function.
        (xml_write_cell): Do not save the style here.  Lookup the style
        id, and write a record with the style id link.
        (xml_sheet_write): Add call to xml_cell_styles_init and
        xml_cell_styles_shutdown to init and shutdown the cell styles in a
        per-sheet basis.

        Renamed functions to suit the gnumeric coding
        sytle.  Fixed indentation.

        File format now saves a different version.  We store all cell
        styles first, and then we reference them.

        (parse_xml_context_t): renamed from
        parseXmlContext.  Add style_table hash table for storing all the
        styles used by the cells on a workbook.  Used to dump Styles first
        and then have the cells reference it.

        * src/style.c (style_hash, style_compare): New routines to
        put Styles on hash tables.

        * src/workbook.c (workbook_sheets): Use g_list_prepend instead of
        g_list_append and reverse the result.

1999-06-14  Miguel de Icaza  <miguel@gnu.org>

        * src/cell.h: Killed ColType and RowType definitions.  They do not
        save any noticeable amount of memory; we are not using them but
        on the most useless places and finally they are the current limit
        to our spreadsheet size.

        * src/gnumeric-sheet.h: Use int instead of ColType, RowType
        * src/item-cursor.h: Use int instead of ColType, RowType
        * src/item-grid.h: Use int instead of ColType, RowType

        * src/print-cell.c (CELL_DIM): Use _pt variants of the margins here.
        (print_cell_text): and here.
        (print_cell): and here.
        (print_cell_range): and here.
        (print_cell_grid): and here.

1999-06-13  Miguel de Icaza  <miguel@gnu.org>

        * src/sheet.c (sheet_compute_col_row_new_size): Update margin_a
        and margin_b from the points.
        (col_row_info_init): New function to initialize a sample
        ColRowInfo.  Inits the _pt fields.
        (col_row_unit_distance): Use the new fields in computation.
        (sheet_col_get_unit_distance): Use new fields in computation.

        * src/dialog-printer-setup.c (do_setup_margin): Set scroll region.
        (preview_page_create): Implement routine that draws the page for
        the margin setup.

        * src/sheet.h (ColRowInfo): Units are now doubles; margin_a_pt and
        margin_b_pt are doubles that represent the a and b margins in
        points.

        * src/sheet.c (sheet_compute_col_row_new_size): Use the

1999-06-11  Miguel de Icaza  <miguel@gnu.org>

        * src/cell-draw.c (cell_draw): Move the foreground setting routine
        here and handle single-line and multiline coloring properly.

        * src/print-info.c (unit_name_to_unit): New routine, returns the
        UniName from the string name.

        * src/dialog-printer-setup.c (dialog_printer_setup): Use
        print_info_save and kill the do_save_settings routine for the
        cleaner print_info routine.

        * src/print-info.c (print_info_new): Now loads the default
        settings from the saved configuration.
        (print_info_save): Saves the print information to the gnome_config.

1999-06-08  Miguel de Icaza  <miguel@gnu.org>

        * src/utils.c (str_trim_spaces): Moved str_trim_spaces ere.

        * src/dialog-printer-setup.c (do_setup_main_dialog): Connect print
        buttons.

        * src/print-cell.c (print_cell_grid): Simplify routine.

        * src/sheet.c (sheet_row_get_unit_distance,
        sheet_col_get_unit_distance): Include  margins in computation.
        This is broken, as the margins are now pixels, and they should be
        made points.

        * src/dialog-printer-setup.c (do_fetch_page_info): Fetch other values.
        (do_save_settings): Saves the configuration.

        * src/print-cell.c (print_border): Implement border drawing.
        (print_cell_grid): Make this work as it should.

        * src/print.c (compute_groups): Handle the case where the contents
        fit entirely in one page.

1999-06-07  Miguel de Icaza  <miguel@gnu.org>

        * src/print.c: New file.  Implements high-level printing.

        * src/dialog-printer-setup.c: New file.  Implements the "Print
        Setup" dialog box.

1999-04-30  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/cell-draw.c: New file.  All of the cell screen drawing code
        has been moved here now.

        * src/print-cell.c: Enhanced code.

        * src/workbook.c: hardcoded page size for testing purposes.

1999-03-10  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        I do not like the current approach.  I do think that StyleFonts
        should be static with regard to Zoom.

        And we would keep a cache of X fonts that are used for a
        particular size.

        * src/style.c (style_font_new_from): New routine that creates a
        new font.

        * src/sheet.c (sheet_set_zoom_factor): Scale fonts used in the
        Sheet.

        page configuration dialog box.

        * src/print-info.c, src/print-info.h: Manages the per-worbook
        print options.

1999-02-07  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/style.c (font_equal): Adapt function to the new StyleFont.
        (style_font_new, style_font_new_simple): Adapt for the upcoming
        gnome-print support.
        (font_init): Adapt.

        * src/xml-io.c: Use Gnome Print font scheme.
        * src/workbook.c: ditto.
        * src/cell.c: ditto.
        * src/item-bar.c, src/item-edit.c: ditto

        * src/dialog-cell-format.c: Disable font selector for now.

1999-06-26  Morten Welinder  <terra@diku.dk>

        * src/fn-financial.c (gnumeric_rate): New function.

        * src/sheet.c (sheet_destroy): Sssshhhh!

        * src/fn-eng.c (eng_functions_init): Extend impower to handle two
        complex numbers.
        (eng_functions_init): Prepare for besseli and besselk.  Docs
        please.

        (gnumeric_skewp): New function.

        * src/mathfunc.c (range_skew_est): Rename from range_skew.
        (range_skew_pop): New function.
        (range_kurtosis_m3_est): New function.
        (range_kurtosis_m3_pop): New function.

        * src/fn-math.c (gnumeric_gcd): Cleanup and fix.

1999-06-24  Michael Meeks  <michael@edenproject.org>

        * src/expr.c (error_message_new): Fix stupid bug,
        such that every error was set.

        * src/fn-math.c: Add sumproduct back in.

1999-06-24  Michael Meeks  <michael@edenproject.org>

        before reading it in set_auto_expr.
        (workbook_do_destroy): Add freeing of auto_expr_text.
        (workbook_set_auto_expr): Hacked to cache expression until we
        have a sheet context.

        * src/expr.h: Add extra Parser error type for invalid args.

        * src/fn-financial.c (finance_functions_init): Fix financial
        functions, using 'i' as a token ( invalid ).

1999-06-23  Michael Meeks <michael@edenproject.org>

        * docs/writing-functions.sgml: Updated to reflect my changes,
        expanded and removed anachronisms.

        * src/expr.h: Added FunctionArgs, FunctionNodes typedefs
        Created struct EvalPosition, struct FunctionEvalInfo and
        implemented through functions where necessary.

        * src/expr.c (function_error, function_error_alloc): created
        helper error return functions.
        (eval_pos_init, eval_pos_cell): Helper EvalPosition fn's
        (func_eval_info_init, func_eval_info_cell, func_eval_info_pos):
        created helper FunctionEvalInfo fn's
        (error_message_new, error_message_set_alloc),
        (error_message_set_small, error_message_txt, error_message_free):
        created error class.

        * src/expr.c (expr_parse_string, gnumeric_expr_parser),
        (expr_decode_tree, expr_tree_invalidate_referenced),
        (expr_tree_fixup_references, eval_expr): Updated to pass / use
        new EvalPosition / FunctionEvalInfo structures.

        * src/parser.y (gnumeric_expr_parser): Updated arguments to use
        EvalPosition, added more stringent checks.

        * src/func.h: Updated lots of things to new structures.
        Changed the iterators arguments to new structures, altered
        FunctionIterateCallback to suit.
        Re-implemented function storage / mapping.

        * src/func.c (function_get_category, function_add_args),

        * src/fn-*: Major major changes:
        - All function definitions changed to use:
        typedef Value *(FunctionArgs)  (FunctionEvalInfo *fe, Value **args); or
        typedef Value *(FunctionNodes) (FunctionEvalInfo *fe, GList *nodes);
        - All error returns altered to use:
                return function_error (ei, _("foo"));
        instead of
                {
                        *error_string = _("baa");
                        return NULL;
                }
        this will allow for changing the error handling.
        - A few functions that used Sheet *, eval_col, eval_row updated.

        * src/collect.c, src/collect.h: New files.

        * src/Makefile.am (GNUMERIC_BASE_SOURCES): Add collect.c and
        collect.h.

        * src/fn-stat.c: Rewrite range-taking using collect and new range
        handling functions.  Most look really nice now.  (This fixes and
        number of leaks and makes error cases handled better.  We might
        return the wrong error from time to time, though.)

        * src/fn-math.c: Ditto.

        * src/expr.c (eval_funcall): Fix insanity check.

1999-06-22  Morten Welinder  <terra@diku.dk>

        * samples/mathfuns.xls: New test file for math functions.

        * samples/statfuns.xls: Accuracy dropped to 1e-5 (since Excel is

        * src/xml-io.c: Fix major thinko in writing fonts.  (The name hash
        table was used to look up a font, which always failed since keys

        patient died.)

1999-05-31  Matt Loper  <matt@gnome-support.com>

        * src/sheet-view.c: Because GNOME::Component was renamed to
        GNOME::BonoboObject, some bonobo function call names needed to be
        changed here (ex. gnome_component_new_view to
        gnome_bonobo_object_new_view).

        (workbook_save): Ditto.

        CHIDIST(), CHIINV(), FDIST(), FINV(), and TDIST() to return the
        complement of the probablity.  It looks like TINV() is still
        broken after file restructurations.

1999-05-26  Morten Welinder  <terra@diku.dk>

        (this is only for inter-workbook copy-paste).

        * src/sheet.c (find_workbook_with_clipboard): Tries to find a
        workbook with clipboard information.  Probably the clipboard

        Add new plugin TXT for simple text inport/export
        tab separated text. multiple sheet in a workbook is separated by

        interpreted as sheet name.

        * src/gnumeric-sheet.c: Add new mean for hard-coded keyboard short
        cut CTRL-Return.  Because ItemEdit does not support XIM, I must
        click the entry whenever I want to input janapese character.  If
        user does not edit the cell, this key combination switchs a
        keyboard focus to entry .

        * Replace gdk_font_load() with gdk_fontset_load()
        src/style.c gdk_font_load() makes impossible to show international
        string.

        * src/clipboard.h 'copy by value' was not possible because of
        miss-definition of PASTE_* enume.

        * src/file.c: gnumeric_notice was called with wrong arguments.

        * plugins/excel/ms-formula.c (parse_data_new): Trap null pointers
        on entry, ( coming from biff_get_text ).
        (ms_excel_parse_formula): Removed nasty static buffers.

1999-02-23  Bruno Unna  <bruno@iac.com.mx>

        * src/dialog-cell-format.c (create_background_radio): Activated
        the patterned background control (although in my machine the
        boxes are all black) and added a radio button to let the
        user do nothing with backgrounds (analogous to the one in
        foreground section).

        * src/dialog-cell-format.c (apply_coloring_format): Now this
        functions takes into account the changes in create_background_radio,
        that is, if the user decides not to change the background,
        the background will not be changed. Also, assigned default
        values to some variables, just to avoid an annoying warning.

        * src/dialog-cell-format.c (create_coloring_page): If there
        are different backgrounds in the range, select by default
        the "no change" radio button for the background.

        default format if no colon is specified

1999-02-22  Tim Mooney  <mooney@dogbert.cc.ndsu.nodak.edu>

        * plugins/guile/plugin.c (func_scm_apply): Initialization of
        structure is done in the function body, rather thatn when it is
        declared.  This is necessary because struct initializer must be
        determinable at compile time, and those aren't.

        * src/expr.c (eval_expr): Add at least one statement to the
        default: handler in the case.

        * src/fn-math.c: provide a break for default handlers.
        * src/item-edit.c (entry_event): ditto
        * src/sheet-autofill.c (fill_item_destroy): ditto.

        * src/dialog-cell-format.c (create_number_format_page): Initialize

        (clear_cell_content): Added a call to workbook_recalc
        (sheet_clear_region_content): same.

1999-02-21  Michael Meeks <michael@imaginator.com>

        * plugins/excel/ms-formula.c FORMULA_PTG_EXP: Fixed several bugs.

        * plugins/excel/ms-excel.c (ms_excel_set_cell_font, biff_font_data_get_style_font):
        Body of the former moved to the latter, loop invariant code removed for
        big speedup.
        (ms_excel_set_cell_xf): Burdern of border color stuff moved to
        (ms_excel_palette_get): New routine to cache and create

        * src/Makefile.am: Use $(GNOME_CONFIG) instead of `gnome-config'
        to run the gnome-config script.
        (BUILT_SOURCES): Swap with GNUMERIC_CORBA_GENERATED to be
        conceptually clean.

1999-02-19  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/fn-misc.c (gnumeric_min): Implement ISERROR.

        * src/clipboard.c (paste_cell): Do not render the value if the
        result is an error.

        * src/cell.c (cell_copy): Do not copy the value of a cell when the
        value is NULL (due to the cell having an error).

        radio button to let the users 'no change' the text colour, useful
        when there is a range selected with differently colored cells
        and it is desired to change the background of them without
        touching the foreground.

        * src/dialog-cell-format.c (create_coloring_page): When there
        are different foreground colours in the selected cells, the
        default selection is 'no change'.

        * src/cell.c (cell_draw): Now the function draws the cell
        using the cell background color setting. Although it does
        the job, I guess there must be a better way to do it. Thanks
        to Michael for the hint.

        * src/item-grid.c (item_grid_draw_cell): Commented out the lines
        involved with patterns display in the cell, for that code is

        formula, always mark it as changed.  We were doing that before
        only for the case where the location had changed, but we use
        cell_relocate in other cases as well.

        * src/fn-string.c (gnumeric_lower, gnumeric_upper): These
        functions were wrong.  They were never incrementing the pointer
        and they were releasing the wrong pointer.

        * src/clipboard.c (paste_cell): When pasting a cell, mark the
        contents as modified.

        * src/file.c (file_saver_is_default_format): Make sure the saver

        argument to bind the dialog boxes properly to the main window.  We
        use gnome_messagebox now to report errors.  We now take a type
        parameter for the message box type.

        * plugins/ff-csv/csv-io.c: Use gnumeric_error

        * src/workbook.c (wb_input_finished): Call sheet_set_current_value
        instead of the cancel pending input routine.

        * src/workbook.c (workbook_configure_minimized_pixmap): Provide an
        icon.  Note that I could not get this to work on fvwm2 though.  I
        will wait for other people to try it.

1999-02-01  Jaka Mocnik  <jaka.mocnik@kiss.uni-lj.si>

        * src/widget-editable-label.c (el_realize): new function.

        * src/fn-misc.c: Added documentation for the functions in this file.

1999-01-26  Bruno Unna  <bruno@iac.com.mx>

        * src/dialog-cell-format.c (create_coloring_page): Now, the
        method to find out whether a cell has been colored or not
        is to compare the RGB values to zero.
        Commented out the attachment of background_radio_list
        because the functionality is not ready yet.

        * src/dialog-cell-format.c (apply_coloring_format): Added support
        for background solid coloring. Howver, changes to the style of
        the cells in this regard have no effect in the display. The reason
        for this is unknown to me as of now.

1999-01-25  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/sheet-autofill.c (sheet_autofill_dir): Add a call to

1999-01-23  Bruno Unna  <bruno@iac.com.mx>

        * src/dialog-cell-format.c: Reactivated the 'Coloring' page
        in struct array cell_format_pages.

        * src/dialog-cell-format.c (create_coloring_page): Lots of
        changes, practically a full rewrite. One problem is that cells
        are thrown into this world with the flag STYLE_FORE_COLOR of
        their style set, which causes a lack of synchronization with
        what is expressed in the global variable foreground_radio_list.

        * src/dialog-cell-format.c (apply_coloring_format): By the moment
        being, deactivated the call of function cell_set_pattern, along
        with the STYLE_PATTERN bit flag of style->valid_flags. I will
        concentrate in fg/bg coloring of the cell.

1999-01-19  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/widget-editable-label.c   (el_init): Set the scroll region
        to something very big.  This fixes the label-sliding problem.
        Thanks to Federico for his quick debugging eye.

        (el_button_press_event): WOW.  I am amazed.  I now gtk grab add
        and if I receive a widget->window different than the canvas, I
        drop the grab and stop editing.

1999-01-19  Francisco Bustamante  <pancho@nuclecu.unam.mx>

        * src/workbook.c (workbook_delete_event)  Return TRUE when the
        workbook should not be destroyed. (i.e. the user presses cancel)

1999-01-19  Jeff Garzik  <jgarzik@pobox.com>

        * src/dialog-cell-format.c, src/gnumeric-util.c,

        Renamed deprecated Gtk+ functions.

1999-01-18  Bruno Unna  <bruno@iac.com.mx>

        * src/dialog-cell-format.c: Now the terminator element of the
        cell_format_pages has three null elements (as stated in the struct
        definition), instead of two. Fixed up some comments. Started
        to pursue the bug that causes that when adding the "Coloring"
        tab the program generates a Gdk-ERROR. Modifications not commited.

1999-01-17  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/gnumeric-sheet.c (gnumeric_sheet_can_move_cursor): Do not

        (workbook_save_as): ditto.

1999-01-10  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/format.c (format_value): Use 0.0########## instead.  Looks saner.

1999-01-10  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/workbook.c (change_auto_expr_menu): Use the event->button
        field to get the popup menu to behave correctly.
        (workbook_setup_auto_calc): Put the information display inside a
        GtkFrame.

        we are realized.

        * src/workbook.c (sheet_label_button_press): We need to do the
        page flipping ourselves, as the GtkNotebook wont take events if
        they are not for a window it knows about.

        * src/widget-editable-label.c (el_button_press_event): Forward
        events to parent.

        * src/parser.y: New non-terminal "cellref".  Make this
        non-terminal include CELLREF and SHEETREF!CELLREF constructions.

        * src/expr.c: Changed the whole module according to the dropping
        of VALUE_CELLREF.

        * src/expr.h: VALUE_CELLREF did not make much sense.  Better add
        to the ExprTree union a CellRef field specifically for OPER_VAR
        nodes.

1999-01-10  Michael Meeks <michael@imaginator.com>

        * plugins/excel/ms-excel.c (ms_excelReadWorkbook): Only believe the

        enumerations / types.
        (get_style_color_from_idx): Implemented.

        * src/style.h: Major expansion of 'StyleBorderType', massive simplification
        of StyleBorder to use directional [ StyleSide ] arrays instead of lots of
        unique member names.

        * src/style.c (border_equal, border_hash, style_border_new,
        style_border_new_plain): Major overhaul and shrink to fit new structure.

        arrays and struct.

        * src/cell.c, src/cell.h: Added cell_set_border.

        sheet_accept_pending_input instead of sheet_set_current_value.
        (workbook_setup_auto_calc): Stick the information display inside
        the status bar.

        * src/eval.c (add_value_deps): Reorganization.  Hanlde

        routine that returns an ExprTree relocated.

        * plugins/excel/ms-excel-biff.h: Split from ms-biff.h removing all

          to compile you need to update your libxml from the CVS tree too.
          Not a definite solution I'm thinking about a more general API
          for XML tree values encoding/decoding. I modified the endoding
          format but backward compatibility should be maintained.

1998-10-23  Federico Mena Quintero  <federico@nuclecu.unam.mx>

        Right/Down expand.
        (selection_expand_vertical): likewise.

        * src/format.c (format_number): Fixed memory leak: this is a

        cells that depend on the contents of the argument.
        (cell_set_format_simple): New routine, like cell_set_format but

        Reordered this file to have the help always before the function
        that defines it.

        to be TRUE.
        (gnumeric_fact): Use exp (lgamma (n+1)) to compute large

        Note that jannuary 1st is day 1, not day zero.

        (split_time): Fixed silly mistake I did last time I looked at this code

        * src/cell.c (cell_set_formula): Try to set the cell style if the
        style is General.

        format matching engine.

        * autogen.sh (PKG_NAME): Another hack to get rid of the annoying

        * src/number-match.c (compute_value): New file:  Implements a
        smart way of parsing numbers:  From all of the registered formats,
        it creates regexps for matching at the time the user inputs data.
        If that data matches any of the regexps, then the input is
        converted into a float, and a display format is assigned to it.

        * src/format.c (append_day, append_month): Skip the -now included-
        start at the begining for internationalization purposes.
        (split_time): Fixed the hour and second renddering.

        * src/sheet.c (sheet_selection_paste): Simplified as most of the
        work is now

        * src/clipboard.c (x_selection_received): Perform the paste
        operation, moved most of the logic from sheet.c.  This does both
        internal paste and paste from the X selection (and everything
        works the way the user expects it to behave).

1998-09-27  Miguel de Icaza  <miguel@nuclecu.unam.mx>

        * src/gnumeric-sheet.c (gnumeric_sheet_key): Last fix was a little

        in the range expected by Microsoft Excel [1900,1900+65535].  We of
        course work on a wider range than Excel can.  We can work on
        pre-1900 dates and on 1900+2^31 dates, but it might make little sense.

        NULL is never returned from format_value now: if there is a format
        error, then value_string is used to display it.

        (format_compile): This routine should always return, it cant fail,
        in the worst * case it should just downgrade to simplistic formatting.

        (format_destroy): This routine is invoked when the last user of
        the format is gone (ie, refcount has reached zero) just before the
        StyleFormat structure is actually released.  resources allocated
        in format_compile should be disposed here

        single style that is attached to a region and let each property
        page fill the structure in.

        This is required for adding the regions of style application in a
        Sheet.

        (cell_set_format): New routine to change the format of an existing
        cell.

        * src/format.c (format_number): Added color argument;  smaller

        of the ExprTree between cells.
        (do_expr_decode_tree): Decoding an expression now takes into
        account the precedence of the operators and uses paretheses only
        when they are actually required.

        * src/numbers.h: Compatibility functions to make the code work
        with or without GMP.
