PyGTK 2.12.0 released
by Johan Dahlin 16 Sep '07

16 Sep '07

PyGTK 2.12.0 is now available for download at: http://ftp.gnome.org/pub/gnome/sources/pygtk/2.12/ gtk+-2.12.0.tar.bz2 md5sum: e9c280afec29b11772af5a7c807abf41 gtk+-2.12.0.tar.gz md5sum: f2534dfaabb3dcff6da04976ef8d486e pygtk-2.12.0.tar.bz2 md5sum: 3c1a42b774600c353342cfa3782a7d77 pygtk-2.12.0.tar.gz md5sum: 627d5c7c8dd11ef3643e7785c30a8227 What is PyGTK ============= GTK is a toolkit for developing graphical applications that run on systems such as Linux, Windows and MacOS X. It provides a comprehensive set of GUI widgets, can display Unicode bidi text. It links into the Gnome Accessibility Framework through the ATK library. PyGTK provides a convenient wrapper for the GTK+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GTK+ library itself PyGTK is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full features applications. What's new in PyGTK+ 2.12 ========================= PyGTK 2.12 adds significant new functionality while maintaining source and binary compatibility with PyGTK 2.10. Highlights of new features and improvements from PyGTK 2.12 are: Tooltips GTK+ 2.12 brings a completely new tooltip implementation which allows many things that were not possible before. Tooltips can be placed on insensitive widgets and on treeviews. They can contain rich markup, or even arbitrary widgets. Interface builder support gtk.Builder can generate user interfaces from XML descriptions which are very similar to glade files. Going beyond the capabilities of libglade, gtk.Builder can also construct objects which are not widgets, such as tree models. New widgets and objects * gtk.VolumeButton, a volume control for multimedia applications * gtk.ScaleButton, the base class for gtk.VolumeButton * gtk.RecentAction, an action that represents a recent-files list Where to get more information about PyGTK ========================================= Information about PyGTK including links to documentation can be found at: http://www.pygtk.org/ Common questions: http://faq.pygtk.org/ Overview of Changes from PyGTK 2.11.0 to 2.12.0 =============================================== The GTK+ Team: Gustavo Carneiro, Johan Dahlin, John Finlay Christian Robottom Reis Special thanks to: Gian Mario Tagliaretti Paul Pogonyshev Thanks to everybody else who has contributed to PyGTK+ 2.12.0:

Announcing Python North-West
by g.lacava＠gmail.com 12 Sep '07

12 Sep '07

On the wave of the great time we had at PyConUK, it was decided we should have a proper mailing list dedicated to English North-West- based Python users... so here it comes! The list is open to everyone in the area who loves coding/playing/enjoying Python. To join, you don't need to know your django from your pylons or your pyqt from your wxwindows... and certainly you don't need to pronounce WSGI. Don't worry, it's going to be uber-informal and very low-traffic, and I promise we won't use lolcats (not much anyway). The group homepage, from where you can subscribe, is: >> http://groups.google.com/group/python-north-west and the email address to use for posting: >> python-north-west(a)googlegroups.com (ideas on how to link this list/announce to other social software are welcome) Best regards, and happy coding!

ANN: pyFltk-1.1.2
by andreas 12 Sep '07

12 Sep '07

Hi This is to announce the general availability of pyFltk-1.1.2. pyFltk is a Python binding for the FLTK GUI toolkit (see http://www.fltk.org) and can be downloaded from http://pyfltk.sourceforge.net. Changes include: - support for Python objects in callbacks - new interactive mode (courtesy of Michiel de Hoon) - resolution of several compilation issues using MinGW and Linux - improved documentation - several bugfixes FLTK and pyFltk are a very simple and intuitive GUI toolkit, enabling you to create professional user interfaces with a minimal effort. For instance, consider the following Hello World program, complete with button callback: from fltk import * import sys def theCancelButtonCallback(ptr): sys.exit(0) window = Fl_Window(100,100,200,90, sys.argv[0]) button = Fl_Button(9,20,180,50) button.label("Hello World") button.callback(theCancelButtonCallback) window.end() window.show(sys.argv) Fl.run() See http://pyfltk.sourceforge.net/examples.php for more examples.

ANN: Porcupine Web Application Server 0.1.1 is out
by t.koutsovassilis＠gmail.com 11 Sep '07

11 Sep '07

This release is mainly a bug fix release, which improves the overall stability of Porcupine. On the server side apart from a couple of annoying bugs being fixed, there is no new feature added. Unlike wise, QuiX includes quite a few important updates. It is now possible for the engine to render semi-transparent widgets by defining their opacity attribute. Drag and drop functionality is also supported by introducing draggables and droppables. Although this functionality is there, it is not yet utilized by the Porcupine desktop. Another new major productivity enhancement is that you can now define the QuiX namespace as the default one; this means that there is no need for namespace declaration (those strange "a:" before each node's tag name) for each one of the nodes of a QuiX document. There is also a new flow box widget, which automatically re-arranges its contained widgets in wrappable rows based on its size. Additionally, have a look at the custom QuiX widgets created for the Porcupine desktop. These widgets include ready made editors for the "Relator1" and "RelatorN" data types and a custom widget for editing each object's security descriptor. They will help you understand how to create your own custom widgets. I hope you'll find this release quite stable and useful.
