I am pleased to announce version 7.2 of the multi-column listbox and
tree widget package Tablelist.

What is new in Tablelist 7.2?
-----------------------------

1. Added the virtual event <<TablelistCopyFinished>>, generated by the
default bindings for the key sequences that terminate the editing
with an automatic postprocessing, when the copying of the new cell
value to some other cells of the column is finished.

2. Added the "-aftercopycommand" configuration option, specifying a Tcl
command to be invoked when after terminating the editing with an
automatic postprocessing, the copying of the new cell value to some
other cells of the column is finished.

3. Added the "-allowduplicates" column configuration option, specifying
whether the interactive cell editing is allowed to set the text of a
cell within the column to the text of some other cell of the column.

4. The demo scripts "bwidget*.tcl", "iwidgets*.tcl", "miscWidgets*.tcl",
and "tileWidgets.tcl" now also demonstrate how to use the new
"-aftercopycommand" and "-allowduplicates" options.

5. On Mac OS X/11+ Aqua the termination of the editing with subsequent
"fill all" action is no longer bound to the <Command-a> event (which
for most widgets on the Mac stands for "select all"), but to
<Control-Command-a> (POTENTIAL INCOMPATIBILITY!).

6. Improved the performance of the photo image creation in the Tablelist
and themepatch code as well as in the demo scripts, by explicitly
specifying the "-format" option.

7. Adapted the scaleutil package to the recent improvements in the
"classic" theme by Emiliano Gavilan.

8. Adapted the default value of the "-selectborderwidth" option in
Tablelist_tile to recent changes in the "default" and "classic"
themes.

9. Eliminated the temporary hang-ups experienced sporadically during
scrolling in the presence of many embedded images (including tree
indentations) or multi-line cells (thanks to Laszlo Zoltan for his
bug report).

How to get it?
--------------

Tablelist is available for free download from the URL

https://www.nemethi.de

The distribution file is "tablelist7.2.tar.gz" for UNIX and
"tablelist7_2.zip" for Windows. These files contain the same
information, except for the additional carriage return character
preceding the linefeed at the end of each line in the text files for
Windows.

Tablelist is also included in tklib, which has the address

https://core.tcl.tk/tklib

How to install it?
------------------

Install the package as a subdirectory of one of the directories given
by the "auto_path" variable. For example, you can install it as a
directory at the same level as the Tcl and Tk script libraries. The
locations of these library directories are given by the "tcl_library"
and "tk_library" variables, respectively.

To install Tablelist on UNIX, "cd" to the desired directory and unpack
the distribution file "tablelist7.2.tar.gz":

gunzip -c tablelist7.2.tar.gz | tar -xf -

On most UNIX systems this can be replaced with

tar -zxf tablelist7.2.tar.gz

Both commands will create a directory named "tablelist7.2 with the subdirectories "demos", "doc", and "scripts".

On Windows, use WinZip or some other program capable of unpacking the distribution file "tablelist7_2.zip" into the directory
"tablelist7.2", with the subdirectories "demos", "doc", and "scripts".

How to use it?
--------------

The Tablelist distribution provides two packages, called Tablelist and Tablelist_tile. The main difference between the two is that
Tablelist_tile enables the tile-based, theme-specific appearance of
tablelist widgets; this package requires tile 0.6 or higher. It is not possible to use both packages in one and the same application, because
both are implemented in the same "tablelist" namespace and provide
identical commands.

To be able to use the commands and variables implemented in the package Tablelist, your scripts must contain one of the lines

package require tablelist ?version?
package require Tablelist ?version?

Likewise, to be able to use the commands and variables implemented in
the package Tablelist_tile, your scripts must contain one of the lines

package require tablelist_tile ?version?
package require Tablelist_tile ?version?

Since the packages Tablelist and Tablelist_tile are implemented in the "tablelist" namespace, you must either import the procedures you need,
or use qualified names like "tablelist::tablelist".

For a detailed description of the commands and variables provided by
Tablelist and of the examples contained in the "demos" directory, see
the tutorial "tablelist.html" and the reference pages, all located in
the "doc" directory.
