Jean-Eloi Dussartre: The Spreadsheet widget, the AtTable object, the 
Xcell demo program.

The main purpose of this project is to provide the AtSpreadsheet widget.
However it was necessary to have some other piece to make it possible to
test. The testing program is Xcell.

To test:

	setenv XENVIRONMENT Xcell.ad
	Xcell -f<filename> -R<# of rows> -C<# of columns>

KNOWN BUG
Feb 1990
	- There is this bug in computing the base line to write in a cell
	  I can't figure out what it is.
	- There is some remaining bug in the scrolling.

TO BE TESTED
May 1990 
	- The support for row / column with different height and row is there
          but it has to be tested. In particular the ability to support
          hidden row / column has not been tested.
	- Try to run it on an RT.


TO BE DONE
        - Setvalue need to be done.
	- The entry points to set the attributs for cells/rows/columns.
	- The handler for cursor move has to handle page scrolling. The 
	  skeleton is there, it has to be written.
	- Most of the library stuff (i.e. think about setvalues and
	  library funtions as short cuts).

KNOWN BUG
	- The spreadsheet widget lose focus once the textedit widget has
          been used. Then the left arrow /right arrow are useless in the 
          spreadsheet widget. Possible fix : accelerator table?

TO BE DONE 
	- Two procedures haven't been implemented I think they are the
          move and copy.
