I am pleased to announce version 6.21 of the multi-column listbox and
tree widget package Tablelist.

What is new in Tablelist 6.21?
------------------------------

1. For the built-in themes "alt", "clam", "classic", and "default", the
"-stripebackground" option now has a nonempty theme-specific default
value (for the "aqua" theme this has always been the case).

2. In disabled state, the "finishediting" subcommand now returns
immediately, without terminating the interactive cell editing
(thanks to Ulrich Seidl for his proposal).

3. Improvements related to the appearance of the Tk core checkbutton
widgets embedded into a header label or a cell (temporarily or
persistently).

4. The (ttk::)checkbutton embedded into the header label of the column
"available" of the tablelist widget created by the demo-scripts for
interactive cell editing now appears in tri-state mode and is
selected/deselected or set into the tri-state mode whenever the
editing changes the value of any cell contained in this column.

5. The scaleutil package now scales more styling options of the
ttk::treeview widget and some styling options of a series of widgets
of the "winnative" theme, too.

6. The scaleutil package now supports also the case that on Xfce the
DPI value was set in the "Fonts" tab of the "Appearance" dialog or
(on Linux Lite 5+) via the "HiDPI Settings" dialog, or on MATE it
was set via the "Font Rendering Details" dialog.

7. The scaleutil package now takes into account that current MATE
versions scale the font DPI for HiDPI displays.

8. The Tablelist distribution now includes the themepatch package,
whose "themepatch::patch" command significantly improves the look
and behavior of the ttk::checkbutton and ttk::radiobutton widgets of
the "alt", "clam", and "default" themes, and makes the "clam"
theme's ttk::button and ttk::menubutton widgets as well as its
ttk::treeview and tablelist headers smaller. If the tk version is
at least 8.7 or the tksvg extension can be loaded into the
interpreter, then the package uses fully scaling-aware SVG images
for drawing the indicators of the patched ttk::checkbutton and
ttk::radiobutton widgets. The demo script "tileWidgets.tcl" now
patches the "default" theme on X11 via "themepatch::patch default".

9. Added support for the case that the "alt" theme was modified by
invoking the "themepatch::patch" command of the themepatch package.

10. Extended the description of the "tablelist::setThemeDefaults"
command by the hint that with current Tablelist_tile versions there
is no need for invocations of this procedure in application code,
and this is now reflected by the demo scripts, too.

11. Fixed two bugs related to the "embedcheckbutton(s)",
"embedttkcheckbutton(s)", "header embedcheckbutton(s)", and
"header embedttkcheckbutton(s)" subcommands (thanks to Adrian
Medrano Calvo for his bug report).

12. Fixed a few bugs related to the comparison of package versions.

13. 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 "tablelist6.21.tar.gz" for UNIX and
"tablelist6_21.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 "tablelist6.21.tar.gz":

gunzip -c tablelist6.21.tar.gz | tar -xf -

On most UNIX systems this can be replaced with

tar -zxf tablelist6.21.tar.gz

Both commands will create a directory named "tablelist6.21 with the
subdirectories "demos", "doc", and "scripts".

On Windows, use WinZip or some other program capable of unpacking the
distribution file "tablelist6_21.zip" into the directory
"tablelist6.21", 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.

Really great stuff, thank you for the detailed work on each visible
pixel. You rock !

I am also happy, that a couple of this work will go into TK8.7.
For me, all this functionality should be in the core.

Thanks again,
Harald
