Weee!  Regular strings are now treated as values (so they
can be used in cell expressions).  This means you can actually
start typing expressions and they will actually make sense
(note that no recalc is yet supported).

The code to do interactive selections is there, but for some
reason the cursor is not paying much attention to me.

This feature lets you select a cell for an expression if you
type in a formula in the spreadsheet (just type '=' and use
the arrow keys to see my buggy code).

More work.

	* 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.

Weee!  I realized that columns were not rows and rows were not
columns.  Cell storage manager works now.

Now I also keep a hash table with the cell contents just for the
lookup portion of the code.

Also the code for displaying various alignements is there give
or take a couple of off-by-ones clipping rectangles (the code
right now has hardcoded styles so different columns have different
alignment styles, just in case someone tested this).

Miguel.

Lots of work: parser, symbol management, cell storage, finally some
cell content rendering, currently it is in debug mode, so you wont see
much.

	* src/gnumeric-sheet.c src/item-bar.c src/sheet.c: Removed the
	canvas parameter from calls to gnome_canvas_item_new().

More work.

Today:
	1. First pass at selections (multiple selections are allowed).
	2. Cursor selection works.  Do not try to drag outside the
	   window though, there is a little bug to be fixed and it will
	   keep a pointer grab.
	3. Started to add destructors all over the place, better to
	   keep an eye on those memory leaks since the beginning.

Miguel.

Typing text into cells feels almost like Excel (modulo the fact that
my input line is not as cute).  No Cell manager yet, so everthing yuo
type is gratiously dropped.  Very baboon like.

Also, some notes from one hour figuring Excel.

	* src/item-bar.c (item_bar_event): Do world->canvas cordinate
	conversion to get zoomed resizng working).

	* src/sheet.c (sheet_row_set_height): Silly mistake, add the newly
	created rowinfo to the row array, not the column array.

Lots of stuff.

Mouse resizing columns and rows is fully working.  Other random
internal goodies, the engine is nicer, the code is nicer, the stuff is
starting to make sense, etc.

It is nice to `see' what it does right now.

Miguel.

1998-07-10  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/style.c: New file.  Implement the style manager for the
	spreadsheet.

1998-07-09  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/*: Dropped the ColInfo and RowInfo structures, they are now
	unified into a single ColRowInfo structure, they were really the
	same thing.  Thanks to Federico for the suggestion.

Total excitement! (take two, as the previous ChangeLog message was
discarded because someone commited before me).

Cool stuff today: we got the columns and rows displayed, with nice
cursor change working; New canvas paint item strategy works very
nicely (much better than the previous stuff); got a region-cursor
working with various of selection modes (still have to figure out how
to draw selected stuff though); basic cursor movement works for now;
sample demo of the toy is included.

Miguel.

Ok, the fact that life sucks manifests itself in various ways.

First of all GDK_INVERT and GDK_XOR gc functions do not do
what you want them to do, but what they are supposed to do, so
my cursor instead of being a nice black and firm box, is just
a pinkie thingie on my Indy.

Second, I got all of the grid draw logic wrong.  That is not
the way Excel does it, so tomorrow, I rewrite it.

Miguel.

More work.  It displays the Grid Item now.
Exposes are hossed on the Canvas, need Federico to fix it.
Next step: style allocator.
