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 &lt;tclconference AT googlegroups DOT com&gt; no later than August 27, 2012. Authors of accepted abstracts will have until October 29, 2012 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 25 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 August 6, 2012. Specific instructions for reserving WIP and BOF time slots will be provided in the registration information available in June 2012. Some WIP and BOF time slots will be held open for on-site reservation. All attendees with an interesting work in progress should consider reserving a WIP slot. Registration Information More information on the conference is available the conference Web site (http://www.tcl.tk/community/tcl2012/) and will be published on various Tcl/Tk-related information channels.

This version should work with all versions of Growl, including the latest version distributed with the App Store. More details here: http://www.codebykevin.com/blosxom.cgi/2012/02/26#tclgrowl Thanks to Steve Landers for his contributions to this package. </pre> Kevin Walzer 2012-02-27T03:17:26 http://permalink.gmane.org/gmane.comp.lang.tcl.mac/7021 <pre>Hi all, Apple released Xcode 4.3 this week, and the new version has some significant differences over previous iterations of the IDE. Xcode no longer installs in /Developer, but is instead a single app bundle that installs in /Applications. Additionally, Xcode no longer installs numerous command-line tools such as llvm, clang, gcc, etc. These can either be installed from Xcode 4.3's preferences menu, or as a separate download from Apple's developer site. The reason I'm mentioning this is that I ran into significant issues trying to patch and build a new version of Tk with Xcode 4.3. (I'm not alone in this respect. Many open-source projects, such as MacPorts, Fink, and Homebrew are also finding a lot of their packages are breaking because of the changes in Xcode.) Tk couldn't find standard headers like stdio.h, let alone the Cocoa and Carbon headers it depends on for the Aqua version. After a lot of Googling, trial and error, I got a new build of Tcl and Tk to work. Here's what I did: 1. Before installing Xcode 4.3 from the Mac App Store, I removed all previous installations of Xcode using the uninstall script that is found in /Developer. (Xcode 4.3 also allows you to do this.) I did this to avoid path conflicts. 2. Installed Xcode 4.3 and the command-line tools. 3. Ran this command: sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/. This command points system resources to the correct header paths, command-line tools, etc. if you have the full Xcode installation. After this, I had to rebuild Tcl and Tk from scratch, and everything ran smoothly. Apple also has made the command-line tools available as a download that does not require the full Xcode installation. I haven't tested this setup, so I can't speak to how it works with open-source software; my guess is that the xcode-select command would need to be run, possibly to point to a different location. The list archives and bug trackers of MacPorts, Fink, and Homebrew are full of discussion about this over the past several days, and it's not fully clear to me how they are resolving the issue or what setup they are recommending for end users. This release of Xcode was a bit bumpy for open-source projects, and I hope this basic discussion of what worked for me will be helpful to others.

If you check the list archives and the bug reports at SF, you'll see various reports, investigations (many by me), and discussions. Bottom line, this is extremely complex to address and I've found it frankly beyond my skill. Integrating Tk and Cocoa's event loops seems to be a much more complicated process than Carbon's; that is what Daniel Steffen has indicated. Its sheer complexity may make the integration more fragile and bugs harder to address. I'd welcome your input if you have time to take a look. I've found the internals of the event loop so hairy that I've not been able to make any headway, and have more or less punted in case someone else wants to take a stab at it. Thanks, Kevin </pre> Kevin Walzer 2012-02-13T22:20:32 http://permalink.gmane.org/gmane.comp.lang.tcl.mac/7017 <pre>Hi, I've been trying to port an application to Tk Cocoa and one of the differences I've been running into is display refresh. I don't know if there is just one problem or multiple problems, but it seems like updates from the Tk side are prioritized lower than in Carbon. Observations on 10.6 (all differences from Mac/Carbon, Windows, and X): 1) if you make changes to a canvas widget, and then take it offscreen, the changes are not visible the next time you bring it onscreen (instead they come after a short delay) 2) when extending the size of a window by PACKing something onto the bottom, the sequence happens thusly: a) the window size is extended; b) the entire contents of the window are redrawn starting from the new bottom; c) the height information for the contents of the new piece start getting paid attention to, which causes a second redraw of the contents back in the original position 3) the bug here (http://sourceforge.net/tracker/?func=detail&amp;aid=3166688&amp;group_id=12997&amp;atid=112997), where using pack / pack forget to switch a tabbed display fails to refresh in timely fashion Before I dive into the event loop and display refresh code in Tk Cocoa (and who knows if I'll come out), has anyone else taken a look at this and/or have any insights or suggestions to offer from other experience with refresh/event loop in Cocoa or Tk? thanks, Adrian ------------------------------------------------------------------------------ Try before you buy = See our experts in action!

For this particular plugin, the 64-bit binary side needs to use the Tcl.framework, and the included one is only 32-bit.

Thanks x </pre> xi0n0ix 2011-10-25T13:56:53 http://permalink.gmane.org/gmane.comp.lang.tcl.mac/7008 <pre>Hi all, I'm posting this here because a few of the list members make use of the Growl notification system (http://growl.info) in their apps. Growl has just released a new version that makes significant changes in its API--these changes are for compatibility with Mac App Store requirements and also to put the system on firmer developmental footing moving forward. Unfortunately, these changes also break many of the third-party language bindings for Growl. I've been informally maintaining two separate Tcl-Growl integration packages--one, macgrowl, is of my own creation and is a Tcl wrapper for Growl's AppleScript interface. The other, tclgrowl, was a "native" Objective-C library developed by the Growl team itself but was largely abandoned (I cobbled a TEA-compliant package out of it and host it at my SVN repo at SF). Neither package works with the new version of Growl. Since many of my commercial Tcl/Tk apps support Growl, I'm going to be putting together some sort of new package for Growl integration with Tcl, but I haven't yet decided how to proceed. Growl's "native" notification system uses a new network protocol that is completely incompatible with the old system. Its new AppleScript API requires fewer changes, but may not play nice with Apple's new "sandboxing" requirements in Lion and the Mac App Store. I don't yet have a timeline for implementing a new Growl package; it partly depends on how much work will be involved. I've asked the Growl team for some guidance on this. In the meantime, once I do have something ready, it will be released open-source somewhere, and I'll post an announcement here.
