I am pleased to announce version 1.15 of the scrolling utilities package
Scrollutil.

What is new in Scrollutil 1.15?
-------------------------------

1. The plainnotebook widget now supports the navigation between the
selectable tabs via the mouse wheel (thanks to Harald Oehlmann for
his TIP 591 and proposal), as well as with the keys "Down", "Up",
"Control-Tab", and "Control-Shift-Tab".

2. The scrollednotebook widget now provides two arrow buttons placed on
demand in the top-left and top-right or bottom-left and bottom-right
corners (depending on the notebook's style), used for scrolling the
tab row (thanks to Harald Oehlmann for his proposal).

3. The scrollednotebook widget now correctly interprets the x coordinate
within an index of the form "@x,y" or passed to the "identify"
subcommand as being relative to the scrollednotebook widget (rather
than the ttk::notebook contained in the latter).

4. Corrected a typo in the implementation of the
scrollutil::addMouseWheelSupport command.

5. Made the detection of the desktop environment when calculating the
scaling percentage corresponding to the display's DPI scaling level
on X11 more reliable (thanks to Florian Pigorsch for his bug report).

6. Numerous further improvements in the code, the demo script
"PagesManDemo.tcl", and the helper script "styleUtil.tcl", which is
source'd in all demo scripts.

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

Scrollutil is available for free download from the Web page

https://www.nemethi.de

he distribution file is "scrollutil1.15.tar.gz" for UNIX and
"scrollutil1_15.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 "scrollutil1.15.tar.gz":

gunzip -c scrollutil1.15.tar.gz | tar -xf -

On most UNIX systems this can be replaced with

tar -zxf scrollutil1.15.tar.gz

Both commands will create a directory named "scrollutil1.15", with the
subdirectories "demos", "doc", and "scripts".

On Windows, use WinZip or some other program capable of unpacking the
distribution file "scrollutil1_15.zip" into the directory
"scrollutil1.15", 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 widget; 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 "scrollutil" namespace and provide identical commands (except for
the "scrollutil::scrollednotebook" command, which is 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.

Csaba,
thank you so much, I really appreciate.
It is time to also obsolete the page manager of BWidget, as this was the
last point which was only available there.

Thank you,
Harald
