Currently wxPython is available for Win32 platforms and the GTK
-toolkit (wxGTK) on most *nix/X-windows platforms. The effort to
-enable wxPython for wxMotif will begin shortly. See \helpref{Building
-Python}{wxpbuild} for details about getting wxPython working for you.

So why would you want to use wxPython over just C++ and wxWindows?

of the program in Python.
days or longer with C++. Converting a wxPython app to a C++/wxWindows app
should be a straight forward task.

\item Build wxWindows with \tt{wxUSE_RESOURCE_LOADING_IN_MSW} set to 1 in
\tt{include/wx/msw/setup.h} so icons can be loaded dynamically. While
there, make sure \tt{wxUSE_OWNER_DRAWN} is also set to 1.
-
\item Change into the \tt{\$(WXWIN)/utils/wxPython/src} directory.
-
\item Edit makefile.vc and specify where your python installation is at.
You may also want to fiddle with the \tt{TARGETDIR} variable as described
above.
-
\item Run \tt{nmake -f makefile.vc}
-
\item If it builds successfully, congratulations! Move on to the next
step. If not then you can try mailing the wxwin-developers list for
help. Also, I will always have a pre-built win32 version of this extension module at
\urlref{http://alldunn.com/wxPython}{http://alldunn.com/wxPython}.

diagnositc or test info to standard output, so they will require the
console version of python. For example:

To run them without requiring a console, you can use the \tt{pythonw.exe}
version of Python either from the command line or from a shortcut.

yourself, you will get everything installed that you need simply by
doing \bftt{make install}. If you get Python from an RPM or other
pre-packaged source then there will probably be a separate package

\item Edit \tt{Setup.in} and ensure that the flags, directories, and toolkit
options are correct, (hopefully this will be done by \tt{configure}
soon.) See the above commentary about \tt{TARGETDIR}. There are a
few sample Setup.in.[platform] files provided.

\bftt{make install} to install the wxPython extension module.

enough to notice the similarities in the classes used.
Take a look at the following wxPython program. You can find a similar

Python and wxPython are properly installed, you should be able to run
it by issuing this command:

\item At line 2 the wxPython classes, constants, and etc. are imported
into the current module's namespace. If you prefer to reduce
namespace polution you can use "\tt{from wxPython import wx}" and
then access all the wxPython identifiers through the wx module, for
example, "\tt{wx.wxFrame}".
-
\item At line 13 the frame's sizing and moving events are connected to
methods of the class. These helper functions are intended to be like
the event table macros that wxWindows employs. But since static event

that the first arguemnt to the event helpers is always the window that
the event table entry should be added to.

to wxPython since Python can't do method overloading like C++.

\item There is an \tt{OnCloseWindow} method at line 34 but no call to
-EVT_CLOSE to attach the event to the method. Does it really get
+EVT\_CLOSE to attach the event to the method. Does it really get
called? The answer is, yes it does. This is because many of the
\em{standard} events are attached to windows that have the associated
\em{standard} method names. I have tried to follow the lead of the
C++ classes in this area to determine what is \em{standard} but since
that changes from time to time I can make no guarentees, nor will it

\item At lines 17 to 21 notice that there are no saved references to
the panel or the static text items that are created. Those of you
who know Python might be wondering what happens when Python deletes
coresponding C++ objects. Once the C++ windows and controls are
attached to their parents, the parents manage them and delete them
when necessary. For this reason, most wxPython objects do not need to

deleted. If you ever have the need to forcibly delete a window, use
the Destroy() method as shown on line 36.
-
\item Just like wxWindows in C++, wxPython apps need to create a class
derived from \tt{wxApp} (line 56) that implements a method named
\tt{OnInit}, (line 59.) This method should create the application's
main window (line 62) and use \tt{wxApp.SetTopWindow()} (line 66) to
inform wxWindows about it.
-
\item And finally, at line 72 an instance of the application class is
created. At this point wxPython finishes initializing itself, and calls
the \tt{OnInit} method to get things started. (The zero parameter here is
ignore it for now.) The call to \tt{MainLoop} at line 73 starts the event
loop which continues until the application terminates or all the top
level windows are closed.
