ANN: wxPython 2.7.2.0

Robin · November 8, 2006, 7:59am

Announcing

···

----------

The 2.7.2.0 release of wxPython is now available for download at
http://wxpython.org/download.php. This is expected to be the last
stepping stone in the path to the next stable release series,
2.8.x. We're pushing full speed ahead in order to get 2.8.0 included
with OSX 10.5, and so far we are very close to being on schedule. This
release has some house-keeping style changes, as well as some
user-contributed patches and also the usual crop of bug fixes. Source
and binaries are available for both Python 2.4 and 2.5 for Windows and
Mac, as well some pacakges for varous Linux distributions. A summary
of changes is listed below and also at
http://wxpython.org/recentchanges.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 GTK2, and Mac OS X 10.3+, in most
cases the native widgets are used on each platform.

Changes in 2.7.2.0
------------------

Patch [ 1583183 ] Fixes printing/print preview inconsistencies

Add events API to wxHtmlWindow (patch #1504493 by Francesco Montorsi)

Added wxTB_RIGHT style for right-aligned toolbars (Igor Korot)

Added New Zealand NZST and NZDT timezone support to wx.DateTime.

wx.Window.GetAdjustedBestSize is deprecated. In every conceivable
scenario GetEffectiveMinSize is probably what you want to use instead.

wx.Image: Gained support for TGA image file format.

wx.aui: The classes in the wx.aui module have been renamed to be more
consistent with each other, and make it easier to recognize in the
docs and etc. that they belong together.

     FrameManager --> AuiManager
     FrameManagerEvent --> AuiManagerEvent
     PaneInfo --> AuiPaneInfo
     FloatingPane --> AuiFloatingPane
     DockArt --> AuiDockArt
     TabArt --> AuiTabArt
     AuiMultiNotebook --> AuiNotebook
     AuiNotebookEvent --> AuiNotebookEvent

wx.lib.customtreectrl: A patch from Frame Niessink which adds an
additional style (TR_AUTO_CHECK_PARENT) that (un)checks a parent when
all children are (un)checked.

wx.animate.AnimationCtrl fixed to display inactive bitmap at start
(patch 1590192)

Patch from Dj Gilcrease adding the FNB_HIDE_ON_SINGLE_TAB style flag
for wx.lib.flatnotebook.

wx.Window.GetBestFittingSize has been renamed to GetEffectiveMinSize.
SetBestFittingSize has been renamed to SetInitialSize, since it is
most often used only to set the initial (and minimal) size of a
widget.

The QuickTime backend for wx.media.MediaCtrl on MS Windows works
again. Just pass szBackend=wx.media.MEDIABACKEND_QUICKTIME to the
constructor to use it instead of the default ActiveMovie backend,
(assuming the quicktime DLLs are available on the system.)

Playing with the new wx.GCDC I noticed that the DrawRectangle behaves strange. The width and height seams to be off by 1 px (GCDC draws larger rectangles)

this happens in wxpython 2.7.2.0
but is this is visible in 2.7.1 too.

EVT_AUI_PANECLOSE = wx.PyEventBinder( wxEVT_AUI_PANECLOSE )
EVT_AUI_PANECLOSE = wx.PyEventBinder( wxEVT_AUI_PANEMAXIMIZE )
EVT_AUI_PANECLOSE = wx.PyEventBinder( wxEVT_AUI_PANERESTORE )
mistake right? can’t catch the real EVT_AUI_PANECLOSE event now

Is there a new version of Demo Docs released also?

I get this error from Sourceforge after clicking on
the link at wxPython page.

Could not read file.

Looks like there was an error when building that installer file. I'll get it fixed and upload it again soon.

Another bug in pycrust...
using Python 2.5 on XP.

click on locals()-> shell -> other. crash.
Last time it crashed on expanding "shell".

also crashes when clicking on "other" inside
shell-> __dict__

Hope this helps...

Yes, this is known. There are certain graphics context operations that need to have an 0.5 offset applied to them, along with an adjustment to the width and height, but it hasn't been done for the GDIPlus or Cairo backends yet. Now that the graphics context API is reasonably finalized we'll be able to go back and pick up some of these things that slipped through the cracks along the way.

[For those that are interested the reason for the offset has to do with the floating point coordinate space, and the fact that the "center" of a pixel located at (x,y) is actually considered to be at (x+0.5, y+0.5), so to make it look like the old integer based wx.DC some adjustments need to be done here and there.]

Yep, it does.

This reminds me that PyCrust doesn't do anything special for properties, it just evaluates them as if they were normal attributes. If somebody wants to put the time into it and submit a patch I think that it would nice for PyCrust to be aware that properties are properties and to display them as such in the tree and the display panel.

Looks like somebody (probably me ) changed something that caused a couple of the base package names to be changed, without adding the right tags so the new ones replace the old ones. You'll need to deselect (uninstall) the old packages (libwxbase2.7-0 and libwxgtk2.7-0) first, and then install the new ones. Sorry about that.

Someone on the Matplotlib is having trouble compiling matplotlib against wxPython 2.7.1 on OS-X. I'm going to see if I can give it a try with 2.7.2, but in the meantime, I thought someone here might have some insight. Here's the compiler error:

gcc: src/_wxagg.cpp
src/_wxagg.cpp: In function 'wxBitmap* convert_agg2bitmap(RendererAgg*, Bbox*)':
src/_wxagg.cpp:238: error: conversion from 'wxImage*' to 'const wxString' is ambiguous

/usr/local/lib/wxPython-unicode-2.7.1.3/include/wx-2.7/wx/string.h:676: note: wxString::wxString(int) <near match>

This same error is repeated a bunch.

You need to dereference the image pointer:
