wxPython 4.0.0b2 release

Announcing wxPython 4.0.0b2 =========================== PyPI: https://pypi.python.org/pypi/wxPython/4.0.0b2 Extras: https://extras.wxPython.org/wxPython4/extras/ Pip: ``pip install wxPython==4.0.0b2`` Changes in this release include the following: * Added a deprecated compatibility helper for wx.CustomDataFormat. * Transfer ownership of the wx.EvtHandler object when pushing/popping them, and also for Set/RemoveEventHandler. (#443) * Add missing wx.VScrolledWindow methods listed in the docs as deprecated but still present. (#441) * Fixed copy/paste error in wx.BusyInfo.__exit__ (#449) * Added new tool wxget, (a minimal wx implementation of wget) * Added new tools wxdocs and wxdemos to launch the respective items, fetching and unpacking as required. (#437) * Fixes to ensure that the locale message catalogs are included in the release files. (#464) * Fix wx.ListCtrl.SetItemData to check that the data value is not out of the range of a C long. (#467) * Changed the default port on *nix builds to be GTK3. The new ``--gtk2`` flag for build.py can be used to force a build for GTK2 instead, and the ``--gtk3`` flag still exists, but defaults to True unless ``--gtk2`` is specified. Please note that there is currently no auto-detection of whether GTK3 is available or not, so if you know you need to build for GTK2 then you need to use the build flag, and there is currently no way to specify that flag for builds performed by pip. (#431) * Fix parameter names in Toolbar.AddTool methods to be consistent. (#475) * Remove inconsistent GetVirtualSize method in ScrolledWindow and let it be inherited from wx.Window instead. (#474) * Fix crashing bug caused by importing a module that reinitializes the wxModule system after having imported wxpyTag. (#468) * Fix missing methods in various DataObject classes. (They were actually accidentally marked "private" when they should have been public.) (#480) * Add missing ListCtrl.DeleteAllColumns. (#486) * Various fixes in the demo. * Fixed improper initial scale factor in wx.lib.agw.speedmeter * Fix for calls to wx.Notebook.HitTest calling the wrong instance (base class version) of the method. (#499) * Add wx.Simplebook class. * Fix exception in wx.lib.agw.customtreectrl when calling SortChildren. (#463, #500) * Fix missing imports needed for drawing the legend in wx.lib.plot. (#503) * Fix other instances of list.sort using old cmp-style ordering functions. (#508) * Update SizedControls to do a sanity check on the parent's sizer, as GetSizer can return None for SizedParent under certain circumstances, such as when AUI reparents the control during pane movement. (#523, #537) * Added Vagrant configs for Fedora 23 and Fedora 26, and dropped Fedora 24. Wheels built on F23 can also be used on F24 and F25, and F26 adds Python 3.6 support. * Fix bitwise OR bug in wx.lib.agw.aui.framemanager. (#493) * Fix bugs in wx.lib.plot when saving file. (#526) * Fix integer division bug in ultimatelistctrl. (#528) * Fix bug in wx.SearchCtrl.SetCancelBitmap (#532) * Fixed property grid SetPropertyValue method to not truncate floating point values to integers, and a couple other possible incorrect conversions. (#536) 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 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.
