I am pleased to announce version 1.14 of the scrolling utilities package Scrollutil.
What is new in Scrollutil 1.14?
-------------------------------
1. Improvements in the scaleutil package, related to setting the default
height of the ttk::treeview rows to a value based on the font's
metrics (see the section "More on scrollutil::scalingpct" in
Scrollutil Programmer's Guide for details); several extensions.
2. Pressing and later releasing the left mouse button over the
"closetab" element of a ttk:notebook tab now generates a
<<CloseTabRequested>> virtual event, whose handling by closing the
tab via the notebook's "forget" subcommand if appropriate lies in
the responsibility of the application (thanks to Alexandru Dadalau
for his proposal) (POTENTIAL INCOMPATIBILITY!).
3. The title label as well as the tabs created with the "addlabel" and
"insertlabel" plainnotebook subcommands now have their own styles
"PnbTitle.TLabel" and "PnbLabel.TLabel" (thanks to Harald Oehlmann
for his proposal).
4. Added the plainnotebook "titlepath" subcommand, which returns the
path name of the widget's title label.
5. The Scrollutil distribution now includes the new clampatch package,
whose "clampatch::patchClamTheme" command makes the ttk::button
widgets as well as the ttk::treeview and tablelist headers of the
"clam" theme smaller and significantly improves the look and behavior
of its ttk::checkbutton and ttk::radiobutton widgets. The script
"styleUtil.tcl", which is source'd in all demo scripts, now invokes
this procedure.
6. Fixed a bug related to changing the value of the "-xscrollbarmode" or
"-yscrollbarmode" scrollarea option from "none" to "static" or
"dynamic" (thanks to Bo Berggren for his bug report and valuable
contribution).
7. Several improvements in the demo scripts. For example, they now
retrieve the current theme via "[ttk::style theme use]" when possible
rather than relying on the value of the variable "ttk::currentTheme"
(which is set by the procedure "ttk::setTheme" only).
8. Improvements in the code and documentation, especially in Scrollutil
Programmer's Guide and the description of the plainnotebook widget
(thanks to Harald Oehlmann for his feedback).
How to get it?
--------------
Scrollutil is available for free download from the Web page
https://www.nemethi.de
he distribution file is "scrollutil1.14.tar.gz" for UNIX and "scrollutil1_14.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 "scrollutil1.14.tar.gz":
gunzip -c scrollutil1.14.tar.gz | tar -xf -
On most UNIX systems this can be replaced with
tar -zxf scrollutil1.14.tar.gz
Both commands will create a directory named "scrollutil1.14", with the subdirectories "demos", "doc", and "scripts".
On Windows, use WinZip or some other program capable of unpacking the distribution file "scrollutil1_14.zip" into the directory
"scrollutil1.14", 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.
