ANNOUNCE: GtkSheet-5.0

["Adrian E. Feiguin" <adrian ifir ifir edu ar>]

GtkSheet is a Matrix/Table widget for Gtk+
Originally, it was a variant of GtkClist widget (by Jay Painter) but
it became more than I expected, and actually it has almost nothing to do 
with it.

I would like to say that I have NO experience with other matrix widgets
but those used by the most popular spreadsheets. My intention was to add
to my widget all those features I think are more useful. I think you won't
get  disappointed.

This distribution includes a demo program where you can see many of the
widget's features.

You can download it from my ftp site:
  ftp://ripley.ifir.edu.ar/pub/gtk/gtksheet/gtksheet-5.0.tar.gz

If you have any problem, just let me know. The connection could be quite
slow...

BRIEF DESCRIPTION
=================

GtkSheet is a matrix where you can allocate cells of text.

Cell contents can be edited interactively with an specially designed
entry, based on GtkEntry (so it has the same features).

You can parse text connecting a parser to the "set cell" signal.
(See example 2 in the demo program)

You can change width, height, background color, foreground color, border
color, border style, and many other attributes of the cells.
(see examples in the demo program)

You can use the matrix as a browser with gtk_sheet_new_browser, and the
cell contents could not be edited.

TO DEVELOPERS
==============

GtkSheet is a composite widget: scrollbars, entry, and a button.

I realized that I can gain a lot of time and memory replacing button
widgets with button emulating gadgets. This is one of the main differences
with GtkClist GUI, and I don't use windows to resize rows/columns. 

To allocate memory, I used an array of pointers. I could used a linked
list or a hash table, but I was originally inspired in SC (I wanted to do
a Gtk port for it), so memory allocation routines are inspired on SC's.

I didn't take advantage of the use of glibs, maybe many features could be
 optimized in this way.

GtkSheetEntry is based on the gtk+-0.99.3 realease of GtkEntry, so many
bugs must be fixed, and features must be updated.

I have no experience on XFonts, so I left this part of the attributes
setting to be done by anyone who wants to.
