Submission of Summaries

Tcl/Tk 2018 will be held in Houston, Texas, USA from October 15, 2018 to October 19, 2018.

The program committee is asking for papers and presentation proposals
from anyone using or developing with Tcl/Tk (and extensions). Past
conferences (Proceedings: http://www.tcl.tk/community/conferences.html)
have seen submissions covering a wide variety of topics including:

* Scientific and engineering applications
* Industrial controls
* Distributed applications and Network Managment
* Object oriented extensions to Tcl/Tk
* New widgets for Tk
* Simulation and application steering with Tcl/Tk
* Tcl/Tk-centric operating environments
* Tcl/Tk on small and embedded devices
* Medical applications and visualization
* Use of different programming paradigms in Tcl/Tk and proposals for new
  directions.
* New areas of exploration for the Tcl/Tk language

Submissions should consist of an abstract of about 100 words and a
summary of not more than two pages, and should be sent as plain text
to tcl...@go... no later than August 20, 2018. Authors of accepted
abstracts will have until September 24, 2018 to submit their final
paper for the inclusion in the conference proceedings. The proceedings
will be made available on digital media, so extra materials such as
presentation slides, code examples, code for extensions etc. are
encouraged.

Printed proceedings will be produced as an on-demand book at lulu.com
Online proceedings will appear via
	http://www.tcl.tk/community/conferences.html

The authors will have 30 minutes to present their paper at
the conference.

The program committee will review and evaluate papers according to the
following criteria:

* Quantity and quality of novel content
* Relevance and interest to the Tcl/Tk community
* Suitability of content for presentation at the conference

Proposals may report on commercial or non-commercial systems, but
those with only blatant marketing content will not be accepted.

Application and experience papers need to strike a balance between
background on the application domain and the relevance of Tcl/Tk to
the application. Application and experience papers should clearly
explain how the application or experience illustrates a novel use of
Tcl/Tk, and what lessons the Tcl/Tk community can derive from the
application or experience to apply to their own development efforts.

Papers accompanied by non-disclosure agreements will be returned to
the author(s) unread. All submissions are held in the highest
confidentiality prior to publication in the Proceedings, both as a
matter of policy and in accord with the U. S. Copyright Act of 1976.

Other Forms of Participation

The program committee also welcomes proposals for panel discussions of
up to 90 minutes. Proposals should include a list of confirmed
panelists, a title and format, and a panel description with position
statements from each panelist. Panels should have no more than four
speakers, including the panel moderator, and should allow time for
substantial interaction with attendees. Panels are not presentations
of related research papers.

Slots for Works-in-Progress (WIP) presentations and Birds-of-a-Feather

Re: [MACTCL] building X11 Mac Tcl/Tk on Mac OS 10.12

[nicolas b. <sl1...@gm...>]

Hi guys,
I use an X11 (XQuartz) based version of Tcl/Tk 8.6.8, and it runs fine.
I built separate version for 10.6&10.7, 10.8 and 10.9and above

Tcl is compiled like that:

export CXX=/usr/bin/clang++

export CC=/usr/bin/clang

export
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/opt/X11/include:/sw/bin:/sw/sbin:/opt/local/bin:/opt/local/sbin:/usr/local/bin

export PKG_CONFIG_PATH=
"/opt/X11/share/pkgconfig:/opt/X11/lib/pkgconfig:/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH"

export
SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10
.13.sdk

./configure --enable-threads --disable-symbols

make -j 4 CFLAGS="-mmacosx-version-min=10.9"


Tk is compiled like that:

./configure --enable-threads --enable-xft
--with-tcl=/Users/nico/daylight/lib/tcl8.6.8/unix --with-x
--x-includes=/opt/X11/include --x-libraries=/opt/X11/lib

make  -j 4 CFLAGS="-mmacosx-version-min=10.9" LDFLAGS="-lfontconfig"


and after for distribution purpose:

install_name_tool -id @executable_path/../lib/libtcl8.6.dylib libtcl8.6
.dylib

install_name_tool -id @executable_path/../lib/libtk8.6.dylib libtk8.6.dylib


hope it helps,

I don't have any specifics, but I suspect it might be a permissions or authentication problem, either with wish executable or with XQuartz in general.
Do you have *any* X11 applications that run ok? (not provided by Apple or XQuartz)
Check the system logs for any interesting messages. (System Preferences: Software->Logs)
Maybe an xauth problem?

[MACTCL] Blog entry on Tk-Mac

[Kevin W. <kw...@co...>]

Hi all,

I wanted to mention a blog entry I've just posted highlighting a lot of 
recent work and improvements on Tk-Cocoa, with due credit to Marc 
Culler, Francois Vogel, and Christian Gollwitzer, who have contributed 
an enormous amount to this last round of development:

https://www.codebykevin.com/blosxom.cgi/2017/12/14#tk-cocoa-25

Tk on the Mac is in an increasingly good place these days, not just 
because of its good pace of improvement, but because it is attracting a 
good developer community that is allowing us to make major progress.

Thanks to all,

Kevin

Tk 8.6.6 but also happens with 8.6.4.   Both running on MacOS HIgh Sierra 10.13.2 Beta.

I fully understand that the received wisdom is that Tk should only be run on the main thread, but this is the first time I have ever encountered it not working.

Time for a documentation update methinks.

Re: [MACTCL] Tk in thread on MacOS

[Marc C. <mar...@gm...>]

You don't say which version of Tk you are using, or which version of macOS,
but when I run your script using the current leaf of the core-8-6-branch on
my Sierra system I get a small window with a label inside which says "this
is a label".

That is not to say that all is well with your script.  Wish crashes with a
segfault when the small window is closed.  But it is far from clear to me
how that crash is related to the process of "running Tk on a child thread".

It helps, when discussing problems like this, to try to be extremely
precise with your language.  When Jim says "You are not supposed to use
AppKit (underlying Tk on macOS) on anything but the main thread" I think he
probably means that you are not supposed to call any methods of the
NSApplication object from threads other than the main thread.  Presumably
that is also true for objects like NSView or NSWindow, although in many
cases methods of those objects are necessarily called from the same thread
as the NSApplication methods. But is that happening here?  Maybe.  However,
the fact that a Tk interpreter is running in a child thread does not imply
that any NSApp methods are being executed in that child.  It would surely
be possible for the event queue of an interpreter running in a child thread
to be shared with the main thread, and for the actual calls to
NSApplication methods to be executed by the main thread. Whether that is
happening in this case depends on how the Threads package is implemented.
It will not be possible to understand what is actually going on without
doing some serious debugging work.  Slogans don't suffice.

It also is essential for everyone involved in a discussion of a problem
like this to be running in the same environment.  Would you please try
running your script in the current leaf of the core-8-6-branch?

I wasn't aware that Tk could be run anywhere except on the main thread. 
My understanding is that it's generally a best practice not to run GUI 
code on a background thread, not just Tk and not just on the Mac, but 
all tookits on all platforms; trying to do so is a Bad Thing. Perhaps 
I've been misinformed.

Re: [MACTCL] Tk in thread on MacOS

[Steve L. <st...@di...>]

My experience is in iOS, where Xcode will warn you but still run the resulting program. Best practice is definitely to run on the default queue (a.k.a. main thread). I suspect that at some point in the future this will be a runtime error.

Back to Tk, my question is whether Tk on MacOS should print a warning or throw an error if run on a child thread?  And, if so, does that mean MacOS Tk diverges from other platforms like Windows and Linux. Or should all platforms be consistent?

At very least the documentation should mention the MacOS restriction, but where in the documentation?

Re: [MACTCL] Tk in thread on MacOS

[Jim I. <ji...@ap...>]

You are not supposed to use AppKit (underlying Tk on macOS) on anything but the main thread.  The Xcode team even added a "Main Thread Checker" tool in the latest version of Xcode to flag uses of AppKit not on the main thread:

It is common for GUI frameworks to only want to use the main thread for all their GUI work.

When I tried out your code in wish I saw the label, so it works for me. Only when I tried quitting the application an exception occurred.

[MACTCL] Tk in thread on MacOS

[Steve L. <st...@di...>]

Should Tk work in a thread on MacOS ?

The following script works on Linux and Windows, but not MacOS the toplevel window resizes but the label doesn’t appear.

I can’t find any documentation that says it shouldn’t work.
package require Thread
set id [thread::create]
thread::send $id {
package require Tk
label .l1 -text "This is a label"
grid configure .l1
}

It seems the grid is the problem, because I can see the label widget exists.  Replacing grid with a pack doesn’t fix it.

Can anyone shed some light?

[MACTCL] Request for feedback: wm iconphoto support on macOS

[Kevin W. <kw...@co...>]

Hello all,

I've opened up a "mac-wm-icon" branch on Fossil that adds support for 
the "wm iconphoto" command on macOS. This command lets you set a wm icon 
from a Tk image, and is used on Windows and X11 to customize the icon in 
the window display and taskbar, as appropriate. This command has not 
previously been supported on the Mac. I've implemented this on macOS 
using a Cocoa API call to set the app's icon in the Dock, in native 
dialog boxes, and other contexts appropriate for the platform.

At the script level, the command works as documented, with a few caveats:

wm iconphoto window ?-default? image1 ?image2 ...?

At the script level the command will accept only the first image passed 
in the parameters as support for multiple sizes/resolutions on macOS is 
outside Tk's scope. Developers should use the largest icon they can 
support (preferably 512 x 512 pixels) to ensure smooth rendering on the 
Mac. Smaller icons will be sized to the correct resolution by macOS and 
may appear jagged if they are too small.

Additionally, while images sourced in GIF format will retain their alpha 
channel/transparency when converted to the Mac icon format, PNG images 
will not. As PNG images work just fine with full alpha channel support 
when sourced directly into a Mac icon, this may indicate some issue with 
PNG reading or conversion within Tk. This issue may have been addressed 
by TIP 166, but in any case, fixing the PNG issue is outside the scope 
of this request for feedback. The proposed documentation notes that GIF 
images work just fine.

I'd like feedback on this over the next couple of weeks if possible. 
Suggestions (and patches) are welcome. If there is no significant 
negative feedback, I will commit this change to 8-6-branch and trunk.

Thanks,

Kevin

Submission of Summaries

Tcl/Tk 2017 will be held in Houston, Texas, USA from October 16, 2017 to October 20, 2017.

The program committee is asking for papers and presentation proposals
from anyone using or developing with Tcl/Tk (and extensions). Past
conferences have seen submissions covering a wide variety of topics
including:

* Scientific and engineering applications
* Industrial controls
* Distributed applications and Network Managment
* Object oriented extensions to Tcl/Tk
* New widgets for Tk
* Simulation and application steering with Tcl/Tk
* Tcl/Tk-centric operating environments
* Tcl/Tk on small and embedded devices
* Medical applications and visualization
* Use of different programming paradigms in Tcl/Tk and proposals for new
  directions.
* New areas of exploration for the Tcl/Tk language

Submissions should consist of an abstract of about 100 words and a
summary of not more than two pages, and should be sent as plain text
to tcl...@go... no later than August 21, 2017. Authors of accepted
abstracts will have until September 25, 2017 to submit their final
paper for the inclusion in the conference proceedings. The proceedings
will be made available on digital media, so extra materials such as
presentation slides, code examples, code for extensions etc. are
encouraged.

Printed proceedings will be produced as an on-demand book at lulu.com

The authors will have 30 minutes to present their paper at
the conference.

The program committee will review and evaluate papers according to the
following criteria:

* Quantity and quality of novel content
* Relevance and interest to the Tcl/Tk community
* Suitability of content for presentation at the conference

Proposals may report on commercial or non-commercial systems, but
those with only blatant marketing content will not be accepted.

Application and experience papers need to strike a balance between
background on the application domain and the relevance of Tcl/Tk to
the application. Application and experience papers should clearly
explain how the application or experience illustrates a novel use of
Tcl/Tk, and what lessons the Tcl/Tk community can derive from the
application or experience to apply to their own development efforts.

Papers accompanied by non-disclosure agreements will be returned to
the author(s) unread. All submissions are held in the highest
confidentiality prior to publication in the Proceedings, both as a
matter of policy and in accord with the U. S. Copyright Act of 1976.

The primary author for each accepted paper will receive registration
to the Technical Sessions portion of the conference at a reduced rate.

Other Forms of Participation

The program committee also welcomes proposals for panel discussions of
up to 90 minutes. Proposals should include a list of confirmed

Submission of Summaries

Tcl/Tk 2017 will be held in Houston, Texas, USA from October 16, 2017 to October 20, 2017.

The program committee is asking for papers and presentation proposals
from anyone using or developing with Tcl/Tk (and extensions). Past
conferences have seen submissions covering a wide variety of topics
including:

* Scientific and engineering applications
* Industrial controls
* Distributed applications and Network Managment
* Object oriented extensions to Tcl/Tk
* New widgets for Tk
* Simulation and application steering with Tcl/Tk
* Tcl/Tk-centric operating environments
* Tcl/Tk on small and embedded devices
* Medical applications and visualization
* Use of different programming paradigms in Tcl/Tk and proposals for new
  directions.
* New areas of exploration for the Tcl/Tk language

Submissions should consist of an abstract of about 100 words and a
summary of not more than two pages, and should be sent as plain text
to tcl...@go... no later than August 21, 2017. Authors of accepted
abstracts will have until September 25, 2017 to submit their final
paper for the inclusion in the conference proceedings. The proceedings
will be made available on digital media, so extra materials such as
presentation slides, code examples, code for extensions etc. are
encouraged.

Printed proceedings will be produced as an on-demand book at lulu.com

The authors will have 30 minutes to present their paper at
the conference.

The program committee will review and evaluate papers according to the
following criteria:

* Quantity and quality of novel content
* Relevance and interest to the Tcl/Tk community
* Suitability of content for presentation at the conference

Proposals may report on commercial or non-commercial systems, but
those with only blatant marketing content will not be accepted.

Application and experience papers need to strike a balance between
background on the application domain and the relevance of Tcl/Tk to
the application. Application and experience papers should clearly
explain how the application or experience illustrates a novel use of
Tcl/Tk, and what lessons the Tcl/Tk community can derive from the
application or experience to apply to their own development efforts.

Papers accompanied by non-disclosure agreements will be returned to
the author(s) unread. All submissions are held in the highest
confidentiality prior to publication in the Proceedings, both as a
matter of policy and in accord with the U. S. Copyright Act of 1976.

The primary author for each accepted paper will receive registration
to the Technical Sessions portion of the conference at a reduced rate.

Other Forms of Participation

The program committee also welcomes proposals for panel discussions of
up to 90 minutes. Proposals should include a list of confirmed
panelists, a title and format, and a panel description with position
statements from each panelist. Panels should have no more than four
speakers, including the panel moderator, and should allow time for
substantial interaction with attendees. Panels are not presentations
of related research papers.

Slots for Works-in-Progress (WIP) presentations and Birds-of-a-Feather
sessions (BOFs) are available on a first-come, first-served basis
starting in July 24, 2017. Specific instructions for reserving WIP
and BOF time slots will be provided in the registration information

for on-site reservation. All attendees with an interesting work in
progress should consider reserving a WIP slot.

I see the behavior, and one thing that immediately comes to mind is that 
you are using Control-Shift- as the accelerator and 
Control-Shift-Key-Greater as the binding: those are two different 
accelerators. In my apps I set accelerators such as Control-P and then 
bind all Control-P. I wonder if the control-shift is inadvertently 
causing the event to fire twice. Any reason for the mismatch between 
accelerators?
