I am pleased to announce version 7.3 of the multi-column listbox and
tree widget package Tablelist.

What is new in Tablelist 7.3?
-----------------------------

1. Added the virtual events <<TablelistXViewChanged>> and
    <<TablelistYViewChanged>>, generated when the horizontal/vertical
    view in the tablelist widget's window changes.

2. Significantly improved the performance of "cellconfigure ... -text"
    (thanks to Paul Obermeier for his valuable contribution).

3. Guarded against the case that an embedded image was deleted (thanks
    to Paul Obermeier for his proposal).

4. Made sure that the handling of the <TouchpadScroll> event won't
    pollute the global namespace (thanks to Rolf Ade for drawing my
    attention to this issue).

5. Adapted the handling of the <FocusIn> and <FocusOut> events to recent
    changes made in Tk related to these events and the detail field
    "NotifyInferior".

6. Restored the support for Tcl/Tk 8.4, which was broken due to the use
    of package version numbers with a trailing "-" and of a submodifier
    in text widget indices (thanks to Samuel Brown for his bug report).

7. Fixed a long-standing bug related to the optimization of item
    insertion.


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

Tablelist is available for free download from the URL

     https://www.nemethi.de

The distribution file is "tablelist7.3.tar.gz" for UNIX and
"tablelist7_3.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 "tablelist7.3.tar.gz":

     gunzip -c tablelist7.3.tar.gz | tar -xf -

On most UNIX systems this can be replaced with

     tar -zxf tablelist7.3.tar.gz

Both commands will create a directory named "tablelist7.3 with the
subdirectories "demos", "doc", and "scripts".

On Windows, use WinZip or some other program capable of unpacking the
distribution file "tablelist7_3.zip" into the directory
"tablelist7.3", 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.
