Today:
	Bug fixes.
	Beginning of the cell/backgorund pattern drawing code.
	Include various MiggeeStipplePatterns

Miguel.

Last night hacking:

	- Bound toolbar alignment buttons.
	- Redraw logic fixed (although multi-span single-repaint
	  is still broken).
	- Small other fixes.

Miguel.

Implemented the new strategy for computing the region that should
be redrawn for a given cell.

Basically: got font changing working.

Miguel.

Today:

   Gnumeric had a big design problem:  It did not support
   multiple vies of the same sheet, this has been now fixes.

   Huge changes to adapt to the new SheetView object that is
   a per-view object.

   Some things might be a little broken due to these changes.

Today:

	- Column delete and Row delete work.  Bindings all over the
	  place are working (context menus, menus, etc).

	- Made scrollbars usable and include a tooltip-like thing
	  like Excel does.

	  They still are kind of inacurrate, and I just figured
	  out a terrible design mistake that will be fixed tomorrow
	  (it is kind of big).

	- Various bug fixes to little things I had overlooked in
	  cell insert/shift routines.

Miguel.

Lots of changes during the weekend:

	- New style management code:  All styles are now managed by
	  regions on a sheet (the default region, is attached to the
	  complete sheet).

	- Styles can now be partial: Only some parts of the style
	  might be valid (this is very important).

	- Insert column/Insert row/Shift rows has been fixed and
	  it now computes properly the dependencies on any
	  data change.

	- Linking/unlinking formulas now takes care also of
	  adding/removing the dependencies of the cell.

Miguel.

Last night hacking got us:

	- Column insertion.
	- COlumn shifting (insert and delete).

Next step: row insertion.

Miguel.

Change of strategy:

	- We dont do "smart" autoformat of numbers and strings.
	  That is what the "general" format is for.

MigueL

New value format framework installed.

The idea is that we will precompile formats to avoid parsing the
format everytime a cell is repainted.

1998-08-19  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/format.c (format_value): The new entry point for formating
	values.  This takes a Value instead of a float.
	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

Basically:

	- auto-alignment on cells without style works.

	- Clean ups (use the new cell_ routines).

	- Couple of bug fixes.

	- Figured that aligment code works better if you
	  actually call the routine on the cell.

Miguel

1998-08-19  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/sheet.c (sheet_cursor_set): New function.  Use this instead
	of the view-specific routine (gnumeric_cursor_set).

	* src/gnumeric-sheet.c (gnumeric_sheet_can_move_cursor): ':' is a
	valid separator for activating the cursor-cell selection mode.

	* src/cell.c (cell_auto_align): New function.  This tries to
	auto-align the cell contents depending on the value type.

	* src/dialog-cell-format.c (cell_properties_apply): Create a
	single style that is attached to a region and let each property
	page fill the structure in.
	(apply_align_format): Implement.  No wonder it was not working
	last night.
	(apply_number_formats): Fill the passed Style structure only.
	Remove obsolete code.

	* src/sheet.c (sheet_cell_new): New cells are born with auto-style
	flag turned on.

	* src/clipboard.c (paste_cell): Render the cell after computation
	is finished.  Clean up the usage of the cell manipulation;  make
	auto-style work on pasted cells.

	* src/str.c (string_ref): Return the value referenced.

Alignment dialog box (does not work though, wonder why).

Various fixes to the cursor handling;

Stippled cursors for autofill and drag;

check in before going home.

Miguel.

1998-08-18  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/gnumeric-sheet.c (gnumeric_sheet_compute_visible_ranges):
	Make the selected column and row be always fully visible (ie, use
	the ->last_full_[col|row] instead of last_visible_[col|row].

	* src/cell.c (cell_set_format): Call cell_queue_redraw after
	changing the cell contents.

Today:

	- Cell format dialog box + working number formats.

Miguel.

1998-08-17  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/eval.c (cell_eval): Use the formating routine now.

	* src/expr.c (value_format): Format a Value with a StyleFormat.

	* src/item-cursor.c (item_cursor_set_bounds_visibly): Force a
	canvas update after moving the selection.

	* src/sheet.c (sheet_selection_to_list): New function: generates a
	list of cells from the sheet->selections list.

	* src/style.c: Now styles have a "valid_flag" that has a bit
	turned on for those parts of the style that are actually used.
	This is required for adding the regions of style application in a
	Sheet.
	(style_destroy): destroy only those valid parts in a style.

	* src/dialog-cell-format.c: New file.   Implements the cell/format
	dialog box.

	* src/cell.c (cell_render_value): new routine used to render the
	cell->value into cell->text.
	(cell_queue_redraw): new routine to queue individual redraws of
	the screen.  I believe it is buggy, as the screen does not update
	after an apply in the cell/format dialog box.
	(cell_set_format): New routine to change the format of an existing
	cell.

	* src/format.c (format_number): Added color argument;  smaller
	fixes to use it within gnumeric.

	* src/main.c (main): Include i18n setup as per namsh's suggetion.

Various small fixes + goto dialogs + improved paste special.

Paste special dialog box.
Expression tree decoder (required for copy paste).
Selection walking works properly just like in Excel.

OK, first version of Gnumeric with cut/copy/paste support.

It has a bug or two that I will fix tomorrow first thing in
the morning.

Tomorrow I will also do the "move" region thingie with the
new fix to the canvas from Federico.

Miguel.

Work on the clipboard

Autocalc works (but I managed to break the recursive detection
stuff, will fix that tomorrow).

Quick-computations on the selected area (like Excel) works with
different user-selectable functions.

Fixed the horrible crash due to not removing my strings from the
hash table ;-)

Miguel

It autocalcs!

My technique is incredibly cool!  The engine should support
most excel features for recursive computations (we just need
the dialog boxes now).

It still has a wierdo crash from a mismatched string ref/unref
but that is going to be trivial to fix.

Next step:  Functions in Perl.

Lots of work as usual :-)

Cell lookup is still broken.
More functions!  COUNT, AVERAGE, AND, OR.

Changed the function framework: it is now easier to write
functions that take multiple arguments.

Added some documentation on writing functions.

Miguel.

1998-07-21  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/parser.y (yylex): Numbers are parsed correctly.  Bits of
	Oleo number parsing plugged in.

	* src/util.c, src/util.h: New files with assorted number utilities.

	* src/numbers.h: New file: takes care of using gmp or regular
	double/int.

	* src/expr.c (eval_release_node): Implement.
	(eval_release_value): New function.

	* src/sheet.c (sheet_col_selection_changed,
	sheet_row_selection_changed): Implement.
	(sheet_selection_clear, sheet_selection_clear_only): Splitted
	functionality into two routines.
	(sheet_selection_clear_only): Remove any marks from the bars.
	(sheet_row_set_selection, sheet_col_set_selection): Implement.

	* src/item-bar.c (is_pointer_on_division): Return the column
	changed.

	* src/item-grid.c (item_grid_draw_cell): Fix the computation for
	right indentation.

More work.

Miguel.
