I am pleased to announce version 6.22 of the multi-column listbox and
tree widget package Tablelist.

What is new in Tablelist 6.22?
------------------------------

1. If SVG is supported, i.e., if the Tk version is at least 8.7 or the
tksvg package can be loaded into the interpreter, then the new
variable "tablelist::svgfmt" is set to a Tcl list that you can pass
to the commands that create or manipulate SVG images as the value of
their "-format" option to make sure that your images will be
properly scaled (see the new section "More on tablelist::svgfmt" in
Tablelist Programmer's Guide for details).

2. In the presence of SVG support, added the arrow style "photo0x0",
whose sort arrows are SVG images that will scale automatically
according to the display's real scaling percentage (which can be
greater than 200, the maximum value of the variable
"tablelist::scalingpct").

3. Removed the very rarely needed arrow styles "flat6x4", "flat7x5",
"flat9x6", "flatAngle9x7", and "flatAngle10x7", and added the styles
"flat10x5", "flat12x6", "flat14x7", and "flat16x8".

4. The default value of the "-arrowstyle" option on X11 is now
"photo0x0" if SVG is supported, and (depending on the display's
scaling level) one of "flat8x4", "flat10x5", "flat12x6", "flat14x7",
or "flat16x8" otherwise (POTENTIAL INCOMPATIBILITY!).

5. In the presence of SVG support, added the tree styles "plain",
"bicolor", "white", and "classic", which are quite similar to the
styles "plain*", "bicolor*", "white*", and "classic*", except that
they use SVG images whose sizes are automatically adapted to the
display's real scaling percentage.

6. The BWidget SpinBox and ComboBox widgets used for interactive cell
editing are now scaled according to the display's real scaling
percentage rather than to the value of the variable
"tablelist::scalingpct".

7. If SVG is supported then the temporarily or persistently embedded
checkbuttons as well as the calendar and watch icons of the Iwidgets
dateentry and timeentry widgets used for interactive cell editing
now use SVG images that will scale automatically according to the
display's real scaling percentage.

8. For Tcl versions 8.4 and later replaced the deprecated "trace
variable" and "trace vdelete" invocations with "trace add variable"
and "trace remove variable", respectively.

9. Improvements in the themepatch package, especially regarding the
"default" theme.

10. In the presence of SVG support, the demo scripts now use SVG images
created with the aid of the variable "tablelist::svgfmt", and on X11
the demo scripts "browseTree(_tile).tcl" and "dirViewer(_tile).tcl"
now set the "-treestyle" option to the SVG-based style "bicolor".

11. Guarded against destroying a tablelist widget in which interactive
cell editing is in progress (thanks to Alexandru Dadalau for his bug
report).

12. Several further improvements and minor bug fixes.

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

Tablelist is available for free download from the URL

https://www.nemethi.de

The distribution file is "tablelist6.22.tar.gz" for UNIX and "tablelist6_22.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 "tablelist6.22.tar.gz":

gunzip -c tablelist6.22.tar.gz | tar -xf -

On most UNIX systems this can be replaced with

tar -zxf tablelist6.22.tar.gz

Both commands will create a directory named "tablelist6.22 with the subdirectories "demos", "doc", and "scripts".

On Windows, use WinZip or some other program capable of unpacking the distribution file "tablelist6_22.zip" into the directory
"tablelist6.22", 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 Tcl/Tk 8.4 or higher and 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.
