Ok, fixed the problems with the bounds in the ItemCursor,
but i still cant get events after I do a gnome_canvas_grab
for the case of the dragging selection.

Work on the clipboard

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.

Lots of things today:

- New functions implemented:
	SELECTION(),  SUM(),  IF()

- Autocompute of an expression that applies to the selection.

- Added comparission to the expression grammar.

- Added array values.

Bug fixes as usual and lots other thingies I forget.

	* src/main.c (main): Rename currentWorkbook to current_workbook,
	so that it follows the style of the rest of my code ;-)

	* src/item-cursor.c (item_cursor_init): Add a timeout handler for
	drawing the anted animation.
	(item_cursor_set_bounds): Setup the Canvas Item bounding box when
	the bounds of the cursor change.

	* src/gnumeric-sheet.c (start_cell_selection): Create the
	selection cursor at the same position the regular cursor is.

	(gnumeric_sheet_init): Share colors between items and the canvas.

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).

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

More work.

Miguel.

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.

Editing of cell contents Canvas Item Type + getting the main GUI ready.

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

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.

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.
