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.

	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/fn-math.c (gnumeric_countif): ditto.

	* src/fn-math.c (gnumeric_seriessum): Add check for NULL nodes
	pointer.

1999-07-08  Jody Goldberg  <jgoldberg@home.com>

	* 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>

	* 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
 	statistics.

	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

	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.

	(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

	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

	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

	xml_cell_styles_shutdown to init and shutdown the cell styles in a
	per-sheet basis.

	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.

	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/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.

	* 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.

	GNOME::BonoboObject, some bonobo function call names needed to be

	* 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.

1999-02-23  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	default: handler in the case.

	* src/fn-math.c: provide a break for default handlers.

	* 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

	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

	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.

	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.

	* src/item-bar.c (set_cursor): This routine can be invoked before
	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

	nodes.

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

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

	  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
