ANNOUNCE: wxPython 2.5.4.1
Announcing -- I'm pleased to announce the 2.5.4.1 release of wxPython, now available for download at http://wxpython.org/download.php What is wxPython? - wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit Microsoft Windows, most Linux or other Unix-like systems using GTK or GTK2, and Apple Macintosh OS X. Changes in 2.5.4.1 -- wx.Sizer Add, Insert, and Prepend functions now return a reference to the wx.SizerItem that was added to the sizer, and the wx.SizerItem has a GetRect accessor to give the position of the item on the parent window. Added wx.Sizer.GetItem method which returns the wx.SizerItem for the given wx.Window, wx.Sizer or position index. wxMSW: wx.RadioButtons in the same group no longer have to be consecutive (there may be intervening controls). Without this fix, an out-of-sync assert is generated when clicking on a radio button and then calling GetValue(). Some XRC changes: - Added 'icon' property to wxFrame and wxDialog - No longer ignores menu bitmaps on non-MSW platforms - Notebook page bitmaps are now supported - added system colours and fonts support (based on patch #1038207) wxMSW: fix for [ 1052989 ] TextCtrl.SetBackgroundColour(wx.NullColour) bug. Added wx.PasswordEntryDialog analagous to wx.TextEntryDialog, allows detecting entering an empty string vs. cancel unlike the wx.GetPasswordFromUser dialog function. OGL patch from Shane Holloway: Two simple problems found in the new python ogl code. First is the patch for _canvas.py. Essentially:: dx = abs(dc.LogicalToDeviceX(x - self._firstDragX)) dy = abs(dc.LogicalToDeviceY(y - self._firstDragY)) was incorrect because (x,y) and (self._firstDragX, self._firstDragY) are both already in Logical coordinates. Therefore the difference between the two is also in logical coordinates, and the conversion call is an error. This bug surfaces when you have OGL on a scrollwin, and you are far from the origin of the canvas. The second change in _composit.py basically removes the assumption that the child is in both self._children and self._divisions. Causes many problems when it's not. ;) Fixed GetSaveData and SetSaveData in wx.lib.multisash to not depend on the default way that class objectss are converted to strings. Fixed problem in StyledTextCtrl.Set[HV]ScrollBar that could leave the internal scrollbar visible. Added wx.StandardPaths which provides methods for determining standard system paths for each platform. wxMSW: The window background is now only erased by default if the background colour or background mode has been changed. This better allows the default system themed behaviour to show through for uncustomized windows. Explicit support added for using the correct theme texture for wx.Notebook pages and their children. wx.Image: Added support for alpha channels in interpolated and non-interpolated image rotation. Added ConvertAlphaToMask helper method for turning shades of grey into shades of alpha and a colour. wxGTK2: Reimplemented DoDrawRotatedText() by way of a rotation of an alpha blended text bitmap. It would be better if Pango could draw directly into an wxImage (as FreeType can,) but that is for later... Added wrappers and a demo for the wx.MediaCtrl class, which can play various forms of audio/video media using native codecs install on the system. So far it is only implemented for Windows and OSX. wxGTK: Patch applied for Freeze()/Thaw() for wxTextCtrtl. Added "gravity" for splitter window (patch 1046105). Gravity is a floating-point factor between 0.0 and 1.0 which controls position of sash while resizing the wx.SplitterWindow. The gravity specifies how much the left/top window will grow while resizing. wxMSW: wx.Slider's C++ implementation rewritten to be more maintainable and hopefully less buggy. The position of the labels has also been changed in order to better comply with Microsoft's examples of how to use the control. wxMSW: Fix wx.TreeCtrl to end label editing if the control loses focus (a slightly modified patch 1084592.) Added wx.EXEC_NODISABLE flag for wx.Execute, which will prevent all the app's windows being disabled while a synchronous child process is running. wxMSW: Much work to correct painting (or leaving transparent) of control backgrounds, properly using background themes on XP, etc. Fixed a circular reference problem with wx.Timer. It will now completely cleanup after itself when the last reference to the timer is removed. If you
PyCon 2005 Sprints
PyCon 2005 is just around the corner. PyCon is a great place to meet and collaborate with your colleagues. A great way to collaborate at PyCon is through sprints. A sprint is a multi-day session of intense development organized around extreme programming (XP) ideas such as pair programming. There will be four days, March 19-22, before the regular conference to sprint on a variety of projects. To see what sprints are planned, see: http://www.python.org/moin/PyConDC2005/Sprints There is also useful logistical information there! If you would like to lead a sprint, feel free to add the sprint to that page. If you want to participate in a sprint, visit a sprint-topic page and add your name to the list of attendees so that we know how many people are coming. If you have a question about the sprints, feel free to drop me a line at [EMAIL PROTECTED] Note that you don't have to attend PyCon to participate in a sprint.

ANN: ElementTree 1.2.6 (march 16, 2005)
The Element type is a simple but flexible container object, designed to store hierarchical data structures, such as simplified XML infosets, in memory. The ElementTree package provides a Python implementation of this type, plus code to serialize element trees to and from XML files. ElementTree 1.2.6 is a maintenance release, consisting of 1.2.5 plus a fix for proper expansion of entities defined in internal DTD:s, minor fixes in the HTML parser, and proper serialization also if Python's default encoding has been changed. You can get the ElementTree package from: http://effbot.org/downloads#elementtree Documentation, code samples, and pointers to articles about the Element- Tree package are available from: http://effbot.org/zone/element.htm enjoy /F -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
ANN: cElementTree 1.0.2 (march 2, 2005)
effbot.org proudly presents release 1.0.2 of the cElementTree library, a fast and very efficient implementation of the ElementTree API, for Python 2.1 and later. On typical documents, it's 15-20 times faster than the Python version of ElementTree, and uses 2-5 times less memory. cElementTree 1.0.2 is 1.0.1 plus the missing "iselement" function, and a couple of minor tweaks and bug fixes. The library is available as C source code, and as Windows installers for all recent Python versions. Get your copy here: http://effbot.org/downloads#celementtree The cElementTree module uses some support functions from the standard ElementTree library, and will not work properly without it. If you haven't installed it already, you can get it from: http://effbot.org/downloads#elementtree enjoy /F -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
New Mailing List for PyCon 2005 Attendees
The PyCon organizers have created a mailing list for PyCon 2005 attendees: http://mail.python.org/mailman/listinfo/pycon2005-attendees We've subscribed attendees we had email addresses for. If you are attending PyCon and haven't received a welcome message, then we probably don't have your email address and you should subscribe to get last minute information. Alternatively, you can keep an eye on the archives. We'll remove this list a week or two after PyCon. Jim (P.S. The subsciber list for this mailing list is only viewable by the list administrators.) -- Jim Fulton mailto:[EMAIL PROTECTED] Python Powered!

ANN: Leo 4.3-a4
Leo 4.3 alpha 4 is now available at http://sourceforge.net/projects/leo/ Leo 4.3 is the culmination of more than five months of work. This alpha 4 focuses on plugins: all known plugins are now in leoPlugins.leo. Most plugins now work with the 4.3 code base. This alpha 4 release also adds the frequently-requested Add Comments and Delete Comments commands to Leo's Edit Body menu. The defining features of Leo 4.3: - 1. Leo now stores options in @settings trees, that is, outlines whose headline is '@settings'. When opening a .leo file, Leo looks for @settings trees not only in the outline being opened but also in various leoSettings.leo files. Users can create arbitrarily complex user options with @settings trees. 2. The Preferences command temporarily replaces the outline pane with an outline showing all the @settings trees in effect. The Preferences command also replaces the body pane with a "settings pane". This settings pane allows you to change the settings selected in the outline pane using standard gui widgets. 3. Leo's read/write code in leoAtFile.py has been rewritten to support user-defined tangling and untangling. This is a major cleanup of Leo's core. 4. Leo now contains an excellent Plugins Manager plugin. This plugin enables and disables plugins automatically and tells you everything you need to know about each plugin. This plugin also lets you download plugins from Leo's cvs site. 5. You can install third-party extensions in Leo's extensions directory. Leo will attempt to import such extensions from the extensions directory when normal imports fail. The distribution contains Python Mega Widgets in the extensions directory. What people are saying about Leo "Word outlines are very useful. But Leo makes Word look like a clunky toy." --Joe Orr "Leo is an interactive editor for organizing text fragments hierarchically and sequentially into one or more files and hierarchical folders, without arbitrary limits on the number and size of text fragments and the depth of the hierarchy...Tangle is a tool for combining hierarchically and sequentially organized text fragments into text files, hierarchically grouped into folders, with hierarchical or sequential organization of text within the files, and without arbitrary limits on the size and number of files and the depth of the hierarchy of folders and text nesting within the files." -- Alex Abacus "Leo reminds me a great deal of things I loved when I used Userland's Frontier (an outlining cms with a native oodb) - but Frontier wasn't hackable enough for me, and it wasn't oriented towards coding and literate programming, and you couldn't round-trip rendered pages (big Leo win). This is really a super tool - in a matter of days I've started to use it on all my projects and I still haven't figured out how I lived without it." -- John Sequeira "Leo is EXACTLY the kind of outliner I was looking for--fantastic job!" -- Steve Allen "If you are like me, you have a kind of knowledge base with infos gathered over time. And you have projects, where you use some of those infos. Now, with conventional outliners you begin to double these infos, because you want to have the infos needed for the project with your project. With Leo you can do this too, but if you change text in one place IT IS UPDATED IN THE OTHER PLACE TOO! This is a feature I did not see with any other outliner (and I tried a few). Amazing! Leo directly supports the way I work!" -- F. Geiger More quotes at: http://webpages.charter.net/edreamleo/testimonials.html What makes Leo special? --- - Leo's outlines add a new dimension to programming. - Leo shows you your code and data the way _you_ want to see them. - Leo extends, completes and simplifies literate programming. - Leo's script buttons bring scripts to data. What is Leo? - A programmer's editor, an outlining editor and a flexible browser. - A literate programming tool, compatible with noweb and CWEB. - A data organizer and project manager. Leo provides multiple views of projects within a single outline. - Fully scriptable using Python. Leo saves its files in XML format. - Portable. leo.py is 100% pure Python. - Open Software, distributed under the Python License. Leo requires Python 2.2.1 or above and tcl/tk 8.4 or above. Leo works on Linux, Windows and MacOs X.
