1998-07-30  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* src/sheet.c (canvas_bar_realized):
	* src/gnumeric-sheet.c (gnumeric_sheet_realize): Neat X hack:  set
	the window backing pixmap to NULL, so that the window does not get
	cleared when it receives an exposure event.  It will just leave
	whatever bits were on the window when the expose happened.  This
	allows us to avoid flicker.  *** MIGUEL, LOOK AT THIS ***

	* src/gnumeric-sheet.c (gnumeric_sheet_make_cell_visible): Fixed
	width/height confusion (cut&paste bug).

	* src/sheet.c (new_canvas_bar): Set outrageously big scrolling
	limits.  This has to be fixed to use the real sheet's dimensions.
	(sheet_new): Use correct table expansion parameters.

1998-07-30  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* src/sheet.c (sheet_set_zoom_factor): Use gnome_canvas_scroll_to().

	* src/gnumeric-sheet.c (gnumeric_sheet_set_top_row): Scroll using
	gnome_canvas_scroll_to().
	(gnumeric_sheet_set_top_col): Likewise.
	(gnumeric_sheet_make_cell_visible): Get the offsets using
	gnome_canvas_get_scroll_offsets().
	(gnumeric_sheet_make_cell_visible): Use gnome_canvas_scroll_to().

1998-07-30  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* src/gnumeric-sheet.c (gnumeric_sheet_color_alloc): Query the
	colormap with gtkdget_get_colormap(), because the canvas structure
	no longer has a colormap field in it.
	(gnumeric_sheet_set_top_row): Use the canvas layout adjustment to
	scroll.
	(gnumeric_sheet_set_top_col): Use the canvas layout adjustment to
	scroll.
	(gnumeric_sheet_make_cell_visible): Get the values from the canvas
	adjustments.

	* src/sheet.c (new_canvas_bar): Call gnome_canvas_new() correctly.
	(scroll_to): New helper function to scroll a canvas.
	(sheet_set_zoom_factor): Use scroll_to().

	* src/gnumeric-sheet.c (gnumeric_sheet_create): Do not call
	gnome_canvas_construct() at is does not exist anymore.
	(gnumeric_sheet_new): Use outrageously big values for the canvas
	scrolling region, for now.  This needs to be fixed.
	(gnumeric_sheet_make_cell_visible): Use the canvas layout
	adjustment to scroll.

1998-07-30    <miguel@nuclecu.unam.mx>

	* src/parser.y (alloc_clean): Free the record that tracks the
	allocation records.
	(alloc_clean): Handle Strings.
	(alloc_list_free): New function: cleans up the allocation list.

	* src/gnumeric-sheet.c (gnumeric_sheet_load_cell_val): Fix to use
	the new Strings.

	* src/cell.h: Use the new Strings instead of the Symbols.  That
	was just a stupid idea.

	* src/str.c (string_ref): New file:  Implements string sharing.

	* src/symbol.c (symbol_install): Use our copy of the allocated key
	when installing the symbol.

1998-07-29    <miguel@nuclecu.unam.mx>

	* src/symbol.c (symbol_unref_ptr): New function that does symbol
	unreferencing and if the reference count reaches zero, it also
	sets the value pointed to NULL.

	* src/sheet.c (cell_set_text): Release evaluation tree after
	entering new contents in a cell.

	* src/sheet.h (Cell): We now keep all of the character information
	as refcounted Symbols.

	* src/expr.c (eval_node_release): Renamed and made static.  New
	allocation strategy: EvalTree's top node are now refcounted to
	simplify cell duplication.
	(eval_expr): Now it takes column and row arguments for evaluating
	the expression in that context.
	(expr_parse_string): Same.

	* src/parser.y: Renamed EvalNode to EvalTree.
	(return_cellref): CellRefs now contain offsets relative to the
	current column/row if the references are not absolute.

	* src/gnumeric-sheet.c (gnumeric_sheet_make_cell_visible): Use new
	helper routines for doing the scrolling.  Scroll vertically.
	(gnumeric_sheet_set_top_row, gnumeric_sheet_set_top_col): New
	routines for keeping the contents of the canvas and the bars in
	sync.
	(gnumeric_sheet_new): Take the ItemBars for the columns and rows
	as a parameter now.

	* src/sheet.c (sheet_select_all): New routine: select the complete spreadsheet.

	* src/item-bar.c (item_bar_class_init): Signal now takes an extra
	argument which indicates the beginning of a column selection.

	* src/sheet.c (sheet_selection_col_extend_to,
	sheet_selection_row_extend_to): New methods for implementing the
	extending column and row selection.
	(sheet_row_selection_changed, sheet_col_selection_changed): Now
	they use the new parameter to start the selection.

* Sync some i18n bits...

1998-07-27  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* 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).

Sat Jul 25 14:10:23 1998  Tom Tromey  <tromey@cygnus.com>

	* src/Makefile.am (test_parser_LDADD): Added INTLLIBS.
	(test_format_LDADD): Likewise.
	(check_PROGRAMS): Renamed from noinst_PROGRAMS.

	* src/format.c (do_roundup): Renamed from roundup (my Linux
	install has a 2-argument `roundup' macro in sys/types.h).  Now
	static.

Don't know why it thinks stamp-h.in is changed. Oh well...

More work.

now, oh well, I gave it a shot :)

Copy from pc to pc trough cvs :-)

Elliot can beat this commit message

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.

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.

1998-07-19  Federico Mena Quintero  <federico@nuclecu.unam.mx>

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

* src/Makefile.am (noinst_PROGRAMS): Don't bother installing
`test-format' and `test-token'.

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.

Miguel.
