The **wxWindows** project and library is now known as
**wxWidgets**. Please see here_ for more details.

This won't really affect wxPython all that much, other than the fact
that the wxwindows.org domain name will be changing to wxwidgets.org,
All of the EVT_* functions are now instances of the wx.PyEventBinder
class. They have a __call__ method so they can still be used as
functions like before, but making them instances adds some
-flexibility.
+flexibility that I expect to take advantave of in the future.
wx.EvtHandler (the base class for wx.Window) now has a Bind method that
makes binding events to windows a little easier. Here is its
If you create your own custom event types and EVT_* functions, and you
want to be able to use them with the Bind method above then you should
change your EVT_* to be an instance of wxPyEventBinder instead of a
-function. If you used to have something like this::

aware that you now need to also build the ogl, stc, xrc, and gizmos

+libraries in addition to the main wx lib.
The wxPython.h and other header files are now in
.../wxPython/include/wx/wxPython instead of in wxPython/src. You should
include it via the "wx/wxPython/wxPython.h" path and add
-.../wxPython/include to your list of include paths. [[TODO: Install
-these headers on Linux...]]
+.../wxPython/include to your list of include paths. On OSX and
+unix-like systems the wxPython headers are installed to the same place
+that the wxWidgets headers are installed, so if you building wxPython
+compatible extensions on those platforms then your include path shoudl
+already be set properly.
+
+If you are also using SWIG for your extension then you'll need to
+adapt how the wxPython .i files are imported into your .i files. See
+the wxPython sources for examples. Your modules will need to at least
+``%import core.i``, and possibly others if you need the definition of
+other classes. Since you will need them to build your modules, the
+main wxPython .i files are also installed with the wxPython headers in
+an i_files sibdirectory. It should be enough to pass a -I/pathname on
+the command line for it to find the files.
+
+The bulk of wxPython's setup.py has been moved to another module,
+wx/build/config.py. This module will be installed as part of wxPython
+so 3rd party modules that wish to use the same setup/configuration
+code can do so simply by importing this module from their own setup.py
+scripts using ``import wx.build.config``.
You no longer need to call wxClassInfo::CleanUpClasses() and
wxClassInfo::InitializeClasses() in your extensions or when embedding
wxPython.
+The usage of wxPyBeginAllowThreads and wxPyEndAllowThreads has changed
+slightly. wxPyBeginAllowThreads now returns a boolean value that must
+be passed to the coresponding wxPyEndAllowThreads function call. This
+is to help do the RightThing when calls to these two functions are
+nested, or if calls to external code in other extension modules that
+are wrapped in the standard Py_(BEGIN|END)_ALLOW_THERADS may result in
+wx event handlers being called (such as during the call to
+os.startfile.)

The hack allowing the old "option" keyword parameter has been removed.

reflect those calls to the real ActiveX control. There is also a
script/tool module named genaxmodule that given a CLSID or progID and
a class name, will generate the module for you. There are a few

It is intended that this new wx.activex module will replace both the
older version of Lindsay's code available in iewin.IEHtmlWindow, and
also the wx.lib.activexwraper module. Probably the biggest

(besides events working better without causing deadlocks) is that
events are no longer caught by overriding methods in your derived
class. Instead ActiveXWindow uses the wx event system and you bind
'event' any more times in a single sentence? ;-) ) For example the
StatusTextChange event will also send the text that should be put into
the status line as an event parameter named "Text" and you can access

+Usually these event object attributes should be considered read-only,
+but some will be defined by the TypeInfo as output parameters. In
+those cases if you modify the event object's attribute then that value

+So how do you know what methods, events and properties that an ActiveX
control supports? There is a funciton in wx.activex named GetAXInfo
that returns a printable summary of the TypeInfo from the ActiveX
instance passed in. You can use this as an example of how to browse
wx.TaskBarIcon, then when the frame is closed Python reference
counting takes care of the rest.
