wxPython 4.0.1
by Robin Dunn 03 Feb '18

03 Feb '18

Announcing wxPython 4.0.1 ========================= PyPI: https://pypi.python.org/pypi/wxPython/4.0.1 Extras: https://extras.wxPython.org/wxPython4/extras/ Pip: ``pip install wxPython==4.0.1`` This release is a quick hot-fix of some issues discovered in 4.0.0 just after the release, plus a bit of low-hanging fruit that was easy to squeeze in too. Changes in this release include the following: * A fix for a segfault that happens upon startup on newer linux releases. (#648) * Set LD_RUN_PATH for the wxWidgets part of the build so the wx libs that are loaded by other wx libs can be found successfully. (#723) * Use wxApp::GetInstance to check if there is an existing wxApp object. (#720) What is wxPython? ----------------- wxPython is a cross-platform 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 set of Python extension modules that wrap the GUI components of the popular wxWidgets cross platform library, which is written in C++. Supported platforms are Microsoft Windows, Mac OS X and macOS, and Linux or other unix-like systems with GTK2 or GTK3 libraries. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. What is wxPython Phoenix? ------------------------- wxPython's Project Phoenix is a new from-the-ground-up implementation of wxPython, created with the intent of making wxPython “better, stronger, faster than he was before.” In other words, this new implementation is focused on improving speed, maintainability and extensibility of wxPython, as well as removing most of the cruft that had accumulated over the long life of Classic wxPython. The project has been in development off and on, mostly behind the scenes, for many years. For the past few years automated snapshot builds have been available for those adventurous enough to try it, and many people eventually started using the snapshots in their projects, even for production releases. While there are still some things on the periphery that need to be completed, the core of the new wxPython extension modules which wrap the wxWidgets code has been stable for a long time now. Due to some things being cleaned up, reorganized, simplified and dehackified wxPython Phoenix is not completely backwards compatible with wxPython Classic. This is intended. In general, however, the API differences tend to be minor and some applications can use Phoenix with slight, or even with no modifications. In some other cases the correct way to do things was also available in Classic and it's only the wrong way that has been removed from Phoenix. For more information there is a Migration Guide document available at: https://docs.wxpython.org/MigrationGuide.html The new wxPython API reference documentation, including all Python-specific additions and customizations, and docs for the wx.lib package, is located at: https://docs.wxpython.org/ -- Robin Dunn Software Craftsman http://wxPython.org

Developer docker images
by Barry Warsaw 01 Feb '18

01 Feb '18

With the release of 3.7b1, I’ve updated the semi-official python-dev big ol’ docker image you can use in various CI and development tasks, such as for GitLab CI runners. This image is based on Ubuntu 16.04 LTS, and comes with the latest Python 2.7, 3.4, 3.5, 3.6, 3.7, and git master (now 3.8a0), along with a bunch of other useful tools like mypy, coverage, tox, wget, zip, and git. For more information see: https://gitlab.com/python-devs/ci-images/tree/master The README.md file includes links to the quay.io repository, instructions on the image’s use, and a sample .gitlab-ci.yml file. I’ll be tracking the 3.7 releases now as well. Feedback welcome at: https://gitlab.com/python-devs/ci-images Cheers, -Barry

wxPython 4.0.0 final
by Robin Dunn 01 Feb '18

01 Feb '18

Announcing wxPython 4.0.0 ========================= PyPI: https://pypi.python.org/pypi/wxPython/4.0.0 Extras: https://extras.wxPython.org/wxPython4/extras/ Pip: ``pip install wxPython==4.0.0`` Changes in this release include the following: * Fixes in wx.aui to properly transfer ownership of the menubar, and also some tweaks in the AUI_MDI sample in the demo. (#540) * Added a wx.BUILD_TYPE value to distinguish between development, snapshot, and release builds. The value is also appended to wx.PlatformInfo. (Thanks Mesalu!) * Fix crash when trying to fetch multiple items from a composite data object in wx.DropTarget.OnData. (#550) Also fixed the CustomDragAndDrop sample to not fail on Python 2.7. * Add ability for wxArray wrappers to return a copy of the item in the ``__getitem__`` method. This solves problems where an array that is the return value of some method call is indexed immediately and a reference to the array is not held, which could result in garbage values for the indexed item. Currently this is turned on for just GridCellCoordsArray, but others can be switched in the future if needed. (#297) * Add missing ``wx.GetLocale`` function. (#572) * Add methods to wx.TextCtrl for output "file-like" compatibility. (#578) * Fix object ownership issue for menus added to toolbar items. (#580) * Updated SIP to version 4.19.5. One of the new features of this version is that integer overflows are no longer silently truncated and ignored. In other words, if a wrapped API has a parameter that is a C int type, and you pass a value that is larger than what will fit in that type of integer then an OverflowError exception will be raised. * Fixed wx.richtext.RichTextBuffer.GetExtWildcard to return a tuple of 2 values, as was done in Classic. (#594) * Various fixes in UltimateListCtrl, HyperTreeList and CheckListCtrlMixin. (#592, #349, #612) * Fixes in TextEditMixin to ensure that the new value is passed in the event. (#605) * Fix comparing DataViewItem and TreeListItem objects with None. (#595) * Fix event type name in wx/lib/sheet.py (#613) * The wx.MessageDialog methods which take ButtonLabel parameters are now able to accept either strings or stock IDs. (#607, #276) * Fix wx.EvtHandler.Unbind to work correctly when specifying the handler and it is a bound method. (#624) * Fix OGL's ShapeCanvas to draw properly when the window is scrolled, and to also adjust the mouse coordinates, etc. (#635) * Set a default background color for the generic buttons. (#651) * Fixed HtmlWindow's OnFoo virtual methods so calls to them are propagated to the Python class. (#642) * Fixed wx.CallLater to explicitly hold a reference instead of depending on an uncollectable cycle to keep the instance around. Like before the cycle is broken and the saved reference is deleted after the timer expires and the callable has been called. (#457) * Although it's more or less just an implementation detail, add wrappers for wx.aui.AuiTabCtrl so references to it will get the correct type. (#664) * List-like wrapper classes generated for accessing wxLists and wxArrays now support reverse indexing. (#669) For example:: child = panel.GetChildren()[-1] * Ported some of the classes in Classic's gizmos module from C++ to Python, including LEDNumberCtrl, DynamicSashWindow, and TreeListCtrl. The classes are now located in the wx.lib.gizmos package, with a compatibility module at the old wx.gizmos location. Please note that this TreeListCtrl class is a very different implementation than wx.dataview.TreeListCtrl, although there is some overlap in purpose. In addition, the new TreeListCtrl class is not actually a port from the old gizmos.TreeListCtrl but rather just a thin layer around AGW's HyperTreeList. This means that if you are using a non- default style flag you'll need to pass it to the agwStyle parameter instead of the style parameter. * Fix crash when deleting all wx.dataview.TreeListCtrl items with wxGTK3. (#679, #704) * Fix displaying '&' in the label of wx.RadioBox on GTK. (#39) * Fix problems of the wrong C++ method being called in wx.ProgressDialog on MS Windows. (#701) * Fixed how the scrollbar events are captured in DynamicSashWindow in order to fix regression in the sample. (#687) * Allow extra CLI args to be passed to build.py by setting WXPYTHON_BUILD_ARGS in the environment. * Added context manager methods to wx.DC that explicitly destroys the C++ part of the DC upon exit. Using DCs as context managers is not required, but can be handy in the rare cases where something holds on to a DC for too long, perhaps unintentionally. (#680) * Fixed crash due to too aggressive management of wxModules when we load subordinate extensions that have their own wxModules (wx.html, wx.adv, etc.) (#688) * Fixed StyledTextCtrl.MarkerDefineRGBAImage and RegisterRGBAImage methods to be able to accept any Python buffer compatible object for the pixel data.

[RELEASE] Python 3.7.0b1 is now available for testing
by Ned Deily 01 Feb '18

01 Feb '18

On behalf of the Python development community and the Python 3.7 release team, I'm happy to announce the availability of Python 3.7.0b1. b1 is the first of four planned beta releases of Python 3.7, the next major release of Python, and marks the end of the feature development phase for 3.7. You can find Python 3.7.0b1 here: https://www.python.org/downloads/release/python-370b1/ Among the new major new features in Python 3.7 are: * PEP 538, Coercing the legacy C locale to a UTF-8 based locale * PEP 539, A New C-API for Thread-Local Storage in CPython * PEP 540, UTF-8 mode * PEP 552, Deterministic pyc * PEP 553, Built-in breakpoint() * PEP 557, Data Classes * PEP 560, Core support for typing module and generic types * PEP 562, Module __getattr__ and __dir__ * PEP 563, Postponed Evaluation of Annotations * PEP 564, Time functions with nanosecond resolution * PEP 565, Show DeprecationWarning in __main__ * PEP 567, Context Variables Please see "What’s New In Python 3.7" for more information. Additional documentation for these features and for other changes will be provided during the beta phase. https://docs.python.org/3.7/whatsnew/3.7.html Beta releases are intended to give you the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We strongly encourage you to test your projects with 3.7 during the beta phase and report issues found to https://bugs.python.org as soon as possible. While the release is feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2018-05-21). Our goal is have no ABI changes after beta 3 and no code changes after rc1. To achieve that, it will be extremely important to get as much exposure for 3.7 as possible during the beta phase. Attention macOS users: with 3.7.0b1, we are providing a choice of two binary installers. The new variant provides a 64-bit-only version for macOS 10.9 and later systems; this variant also now includes its own built-in version of Tcl/Tk 8.6. We welcome your feedback. Please keep in mind that this is a preview release and its use is not recommended for production environments. The next planned release of Python 3.7 will be 3.7.0b2, currently scheduled for 2018-02-26. More information about the release schedule can be found here: https://www.python.org/dev/peps/pep-0537/ -- Ned Deily nad(a)python.org -- []
