ANNOUNCE: GtkSheet-5.5

[Adrian Feiguin <adrian ifir ifir edu ar>]

GtkSheet-5.5
============

Many bugs fixed, mainly reported by Mario Motta. 

All warnings fixed. 

Signals: 
"changed" is emited when typing into the active cell, changing its contents. 
"set_cell" is emited when changing current cell's position. 
"activate_cell" is emited when the new cell is activated.

NOTE: gtksheet crashes on Solaris. I couldn't fix this, yet.

GtkSheet-5.4
============

Following Mario Motta's suggestions (mmotta@guest.net) I added a new feature:

You can hide/show row and/or column titles (see Example 2 in the demo program)

and I patched gtksheet.h for C++ compatibility.

I fixed a couple of bugs:
multiple emission of the "activate_cell" signal;
problems when selecting a row/column and moving with the cursor keys. 
 
NOTE: All versions of GtkSheet compile fine with gtk+-1.0.6
Any of the "bugs" reported in the gtk-list has been verified. 

Please, if you have problems I suggest you to verify if you have gtk+-1.1 
intead of gtk+-1.0 installed. If you can't compile, edit the Makefile file. 

I aknowledge to all of you on the list who are using gtksheet and reporting 
problems and bugs. Please, give me your suggestions.
 
GtkSheet-5.3
============

The graphic interface is nicer and more friendly. 
The appeareance is more familiar and I added some new features:

You can make a selection and move it dragging the border.

You can resize the selection dragging the bottom-right corner.

You can store the selection on the clipboard. 

(All this functions emit a signal. You can cutomize your application
 connecting a signal handler in order to do the desired action. See
 the example 1 in the demo program) 

NOTE: the selection handler has not been implemented yet.
The demo program is an application which includes an external entry 
connected with the sheet's entry. The external entry does not belong to the 
widget, the widget has its own entry and the text is edited interactivelly
and "on the site". 
You can download it from my ftp site:
  ftp://ripley.ifir.edu.ar/pub/gtk/gtksheet/gtksheet-5.3.tar.gz
I'm uploading the new version to gtk.org
I hope it will be included in future releases of gtk.

--------------------------------------------------------------------------

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.

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-5.3.tar.gz

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.
