1st stab at scrollbars adjusting to visible region.
    Move selection code into a new file, no changes.
    Minor const fixups.

Re-vamped & improved D&D code moved around too :-)

Fix Bug 1732, 1638.

Add more Biff record types in excel.

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  Miguel de Icaza  <miguel@gnu.org>

	* ms-excel-write.c (biff_put_text): Intiialize variable.

this breaks some peoples stuff, but I'll get on to that now...

1999-06-21  Miguel de Icaza  <miguel@gnu.org>

	* src/func.c: Do not pre-initialize them.  If they need to be
	pre-initialized something is wrong in some other place.  Fix that
	instead.

	* src/clipboard.c (do_clipboard_paste_cell_region): Implement
	transpose-on-paste command.  Change the increment steps for
	transpose and compute a different target column as well.

	(sheet_paste_selection): Swap the paste dimesions here if we are
	pasting/transpose.

1999-06-18  Miguel de Icaza  <miguel@gnu.org>

	* src/func.c: Remove static initialization of the error messages.

1999-06-14  Miguel de Icaza  <miguel@gnu.org>

	* src/clipboard.h: Define PASTE_TRANSPOSE.

	* src/dialog-paste-special.c (dialog_paste_special): Add new

1999-06-12  Miguel de Icaza  <miguel@gnu.org>

	* src/dialog-cell-comment.c (dialog_cell_comment): Process the
	return value from gnome_dialog_run correctly as well.  (ie we
	should catch the return value -1 as the "user closed dialog box"
 	message and avoid destroying the dialog box ourselves).

	* src/item-grid.c (context_paste_special_cmd): Handle a cancel
	operation from the dialog_paste_special dialog box.

	* src/dialog-paste-special.c (dialog_paste_special): Hanlde the
	case in which the window manager closed the dialog box.

	* src/cell.c (cell_comment_destroy): Changed invocation from
	gtk_object_destroy to gtk_object_unref.
	(cell_comment_unrealize): ditto.
	(cell_comment_clicked): ditto.
	* src/dialog-cell-sort.c (dialog_cell_sort): ditto.
	* src/dialog-function-select.c (dialog_function_select): ditto
	* src/dialog-function-wizard.c (dialog_function_wizard): ditto
	* src/dialog-paste-special.c (dialog_paste_special): ditto
	* src/dialog-solver.c (constr_add_click): ditto.
	(constr_add_click): ditto
	(dialog_solver_options): ditto
	* src/gnumeric-sheet.c (gnumeric_sheet_stop_cell_selection): ditto
	(destroy_item_editor): ditto.
	(gnumeric_sheet_key_mode_object): ditto, and clear the pointer to
	the current_object.
	* src/sheet-object-container.c (sheet_object_container_destroy): ditto.
	* src/item-cursor.c (item_cursor_drag_event): ditto.
	(item_cursor_autofill_event): ditto
	* src/item-bar.c (item_bar_event): ditto
	* src/workbook.c (workbook_setup_auto_calc): ditto.
	* src/widget-editable-label.c (el_stop_editing): ditto
	* src/sheet-object.c (sheet_object_destroy): ditto
	(sheet_view_object_unrealize): ditto
	(sheet_object_destroy_control_points): ditto
	* src/sheet-view.c (sheet_view_destroy): ditto

1999-06-10  Miguel de Icaza  <miguel@gnu.org>

	* src/pattern-selector.c (pattern_selector_init): Use the GNOME
	canvas fill_stipple feature instead of using the hack of creating
	the bitmap and setting the stipple on the realize handler.

1999-06-01  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* po/hr.po: Added croat translation from Vladimir Vuksan
	<vuksan@cs.unm.edu>.

1999-06-09  Nat Friedman  <nat@gnome-support.com>

	* src/sheet-view.c (sheet_view_insert_object): Commented out call
 	to gnome_bonobo_object_new_view since the API changed and this
 	function doesn't do anything anyways.

	* src/sheet-object-container.c: Include gnome-component-client.h
 	and view-frame.h.
	(sheet_object_container_land): Pass soc->client_site to
 	gnome_bonobo_object_new_view.  Get the view wrapper widget from
 	the view frame.
	(sheet_object_container_realize): Likewise.

1999-05-31  Matt Loper  <matt@gnome-support.com>

	* src/sheet-view.c: Because GNOME::Component was renamed to
	GNOME::BonoboObject, some bonobo function call names needed to be
	changed here (ex. gnome_component_new_view to
	gnome_bonobo_object_new_view).

	* src/sheet-object-container.c (sheet_object_container_land):
	likewise.
	(sheet_object_container_realize): likewise.

Warning fixes;  Keep up with Bonobo changes;  Render the views in all
of the graphic wizard view bits.

Miguel

1999-04-12  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/clipboard.c (x_selection_to_cell_region): Fixed the
	computation of columns in the paste code.

1999-04-11  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/workbook.c (insert_object_cmd): Add sample bonobo support.
	Still lacking an object server selector.

	* src/sheet.c (sheet_insert_object): Add Bonobo support.

	* src/sheet-view.c (sheet_view_insert_object): Add basic Bonobo
	support.  I need to reuse the SheetObject stuff to add control
	points to the objects and to handle repositioning.

1998-12-16  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* src/workbook.c (workbook_setup_status_area): Do not set_usize()
	on the info item.

	* src/sheet-view.c (new_canvas_bar): Set the width or height to -1
	in set_usize().

	* src/gnumeric-sheet.c (gnumeric_sheet_new): Do not set_usize() on
	the sheet.

1998-12-02  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/gnumeric-sheet.c (gnumeric_sheet_set_top_row,
	gnumeric_sheet_set_top_col): New functions to set the sheet top
	column and row respectively.

	(gnumeric_sheet_bar_set_top_row, gnumeric_sheet_bar_set_top_col):
	Renamed from their old names to reflect their actual action.

	* src/item-cursor.c (item_cursor_autofill_event): Do not pass
	negative numbers to item_grid_find_col and item_grid_find_row.

	* src/item-grid.c (item_grid_find_row, item_grid_find_col): Check
	for possitive numbers. I think the right fix is to accept negative
	numbers and find the column even if the number is negative instead
	of this ugly restriction.

Two things that have been on my hard disk for a long time:

1. Comments-on-cells code is working.  We just need the nice dialog to
actually type something in.

It needs xml-io.c support though, hopefully Daniel will add this soon.

2. Dropped cell->entered_text.  We now only store the parsed version
of the cell (either as an ExprTree or as a Value).  This should help
mmeeks with his Excel-formula importing code, it should be possible
to do the right thing now instead of constructing a string representation
of the formula and re-parsing it.

Various fixes here and there as well.

Miguel

1998-11-10  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/sheet-view.c (sheet_view_comment_get_points): Scale properly
	the points to be in window cordinates.

	* src/sheet.c (sheet_col_set_width): Move comments on column
	change.

	* src/cell.c (cell_copy): Duplicated cells get col, row and sheet
	values set to NULL.

1998-11-05  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/fn-misc.c: Add ctype.h

	* src/sheet-view.c (sheet_view_comment_get_points): New utility
	routine used.
	(sheet_view_comment_relocate): New function used to relocate a
	comment canvas item in a cell to its new location.

	* src/cell.c (cell_relocate): Move the comments with the cell.
	(cell_realize, cell_unrealize, cell_comment_realize,
	cell_comment_unrealize): New functions used to create and destroy
	view-specific cell components (the comments are canvas objects
	that need to be created on a per-view basis).

Get the Excel plugin incorporated into the build process (right now
it is not a real plugin, it gets loaded directly into gnumeric address
space, I guess we can fix this).

Cell comments are working, but still need some work.

Miguel.

1998-10-13  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/utils.c (col_name): It is amazing the number of times I
	duplicated this code.  I wonder if I took prozac by accident.
	This should fix the bug reported by Morten Welinder

	decoding.  I wonder when I will learn.

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

	* src/sheet-view.c (sheet_view_col_selection_changed): Make sure
	the column is allocated (so that the column size change picks up
	the column during the iteration).
	(sheet_view_row_selection_changed): Same

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

	* src/style.c (font_init): New routine: loads a couple of default
	fonts to be used in Gnumeric.

	* src/item-bar.c (bar_draw_cell): Make the SELECTION cells display
	with a bold font.
	(item_bar_realize, item_bar_unrealize): reference and unreference

1998-10-07  Jakub Jelinek  <jj@ultra.linux.cz>

	* src/item-grid.c (item_grid_button_1): Handle shift+click
	on cells (removes last selection and selects from last base
	to current mouse location).
	(item_grid_event): Don't lock up if mouse is moved during
	selection behind left or top margin of sheet canvas (later
	on we should move the current view).

	* src/cell.c (cell_formula_changed): Cast void * to something
	reasonable.

	* src/item-bar.c (draw_bar_cell): Switch from 2 state bars
	to 3 state: whole column/row is selected in one of the current
	selections, some cells are selected in one of the selections
	or nothing is selected. Get rid of ci->selected, compute it
	from the selections.
	(item_bar_draw): Ditto.

	* src/cell.h (selected): Ditto.

	* src/sheet.c (sheet_init_default_styles, sheet_init_dummy_stuff):
	Ditto.
	(sheet_selection_row_extend_to, sheet_selection_col_extend_to):
	Remove.
	(sheet_all_is_selected): True if any of the selections covers whole
	sheet.
	(sheet_col_selection_type, sheet_row_selection_type): New functions.
	(sheet_selection_set): New function.

	* src/sheet-view.c (sheet_view_row_set_selection,
	sheet_view_col_set_selection): Remove.
	(sheet_view_col_selection_changed, sheet_view_row_selection_changed):
	Handle shift+click and ctrl+click on whole columns/bars as well.
	(sheet_view_col_size_changed, sheet_view_row_size_changed): Use
	sheet_*_selection_type instead of ci->selected.

	* src/item-bar.h (ItemBarSelectionType): Enum for the new 3 state
	column/row titles.

1998-10-06  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/cell.c (cell_modified): Cells from the clipboard do not have
	a Sheet parameter attached.

	* src/sheet.c (sheet_cell_add): Check the computed style:  if the
	computed style includes a format, then turn on the cell flag for
	format is set to avoid the auto guess of cell content.
	(sheet_style_compute): Now can return the flags of the style that
	were not part of the default style.

	* src/file.c (dialog_query_load_file, workbook_save_as): Put the
	window close to the mouse.

	* src/workbook.c (sheet_check_dirty, workbook_close): Do not
	cancel without warning the user if the workbook has changed.
	(workbook_new, workbook_can_close, workbook_window_destroy,
	quit_cmd, close_cmd): Reorganized the code to suit the new code to
	prevent inadvertent quits.

1998-09-25  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/sheet.c (sheet_selection_row_extend_to,
	sheet_selection_col_extend_to): New version that makes sure the
	column information has been allocated.

	* src/workbook.c (workbook_parse_and_jump): Maximum ranges were a
	little bit off.

	* src/parser.y (return_cellref): Fixed the same bug we had in
	parse_cell_name:  The parsing of the column name to a column index
	was wrong here too.

	* src/sheet.c (sheet_row_info_set_height,
	sheet_col_info_set_width): New functions based on the older
	non-ColRowInfo versions.

	* src/sheet-view.c (sheet_view_row_size_changed,
	sheet_view_col_size_changed): Apply changes globaly if the whole
	sheet is selected.

New:

	- Bold button works properly (ie, it detects what sort of
	  stuff you have and presses/unpresses accordingly).

	- GNumeric now has operation modes: sheet and object.
	  Using delete/backspace/edit-cut will let you kill
	  objects.

	- Lots of the bug fixes reported by Adrian/Federico.

Miguel

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

	* src/style.h: Color style is now a single color

1998-09-06  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/sheet-object.c: New file.  The support for adding graphical
	objects to the spreadhseet is here.  The main entry point is
	sheet_set_mode_type which hooks to the signal handlers for object
	creation.

	Various routines for per-view creation, destruction are provided.

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.
