I am pleased to announce version 2.3 of the scrolling utilities package
Scrollutil.

What is new in Scrollutil 2.3?
------------------------------

1. Several improvements in the implementation of the scrollarea widget.
For example, made sure that mapping or unmapping the horizontal
scrollbar as a result of resizing the toplevel window no longer
causes the toplevel to get higher.

2. 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).

3. Added the demo script ScrolledCanvas.tcl; improvements in several
other demo scripts.

4. Fixed a bug that under some circumstances caused the dynamic
horizontal scrollbar of a newly created scrollarea widget to get
mapped for a short time, even though the embedded widget's "xview"
command returned the list {0 1}.

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

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

Scrollutil is available for free download from the Web page

https://www.nemethi.de

The distribution file is "scrollutil2.3.tar.gz" for UNIX and
"scrollutil2_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.

Scrollutil 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 Scrollutil on UNIX, "cd" to the desired directory and unpack
the distribution file "scrollutil2.3.tar.gz":

gunzip -c scrollutil2.3.tar.gz | tar -xf -

On most UNIX systems this can be replaced with

tar -zxf scrollutil2.3.tar.gz

Both commands will create a directory named "scrollutil2.3", with the
subdirectories "demos", "doc", and "scripts".

On Windows, use WinZip or some other program capable of unpacking the
distribution file "scrollutil2_3.zip" into the directory
"scrollutil2.3", with the subdirectories "demos", "doc", and "scripts".

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

The Scrollutil distribution provides two packages, called Scrollutil and
Scrollutil_tile. The main difference between the two is that
Scrollutil_tile enables the tile-based, theme-specific appearance of
scrollarea, scrollsync, and scrollableframe widgets, and provides the
themed scrollednotebook and plainnotebook widgets; this package requires
tile 0.8 or higher. It is not possible to use both packages in one and
the same application, because both are implemented in the same
"scrollutil" namespace and provide identical commands (except for the
commands "scrollutil::scrollednotebook", "scrollutil::plainnotebook",
"scrollutil::addclosetab", "scrollutil::removeclosetab", and
"scrollutil::closetabstate", which are provided by the Scrollutil_tile
package only).

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

package require scrollutil ?version?
package require Scrollutil ?version?

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

package require scrollutil_tile ?version?
package require Scrollutil_tile ?version?

Since the packages Scrollutil and Scrollutil_tile are implemented in the
"scrollutil" namespace, you must either import the procedures you need,
or use qualified names like "scrollutil::scrollarea".

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