So why would you want to use wxPython over just C++ and wxWindows?
Personally I prefer using Python for everything. I only use C++ when

then I ususally code it as an extension module and leave the majority
of the program in Python.
There are quite a few other GUI modules available for Python, some in
active use, some that havn't been updated for ages. Most are simple
wrappers around some C or C++ toolkit or another, and most are not

I added a few minor features to SWIG to control some of the code
generation. If you want to play around with this you will need to get
-a recent version of SWIG from their CVS or from a daily build. See

wxPython is organized as a Python package. This means that the
For Win32 systems I use Visual C++ 6.0, but 5.0 should work also. The
build utility currently does not support any other Win32 compilers.
+
\item At this point you may want to make an alias or symlink, script,
batch file, whatever on the PATH that invokes \tt{\$(WXWIN)/utils/wxPython/distrib/build.py} to
help simplify matters somewhat. For example, on my Win32 system I have a file named
\tt{python \%WXWIN/utils/wxPython/distrib/build.py \%1 \%2 \%3 \%4 \%5 \%6}
\item Change into the \tt{\$(WXWIN)/utils/wxPython/src} directory.
+
\item Type "\tt{build -b}" to build wxPython and "\tt{build -i}" to
install it, or "\tt{build -bi}" to do both steps at once.
a different way, take a look at the docstring in build.py. You are
able to to override many configuration options in a file named
build.local.
+
\item To build and install the add-on modules, change to the appropriate
directory under \tt{\$(WXWIN)/utils/wxPython/modules} and run the build
utility again.
+
\item Change to the \tt{\$(WXWIN)/utils/wxPython/demo} directory.
+
\item Try executing the demo program. For example:
\tt{python demo.py}
namespace pollution 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
same to dynamically build the table. The only real difference is
that the first arguemnt to the event helpers is always the window that
the event table entry should be added to.
+
\item Notice the use of \tt{wxDLG\_PNT} and \tt{wxDLG\_SZE} in lines 19
- 29 to convert from dialog units to pixels. These helpers are unique
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
called? The answer is, yes it does. This is because many 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
be fully documented. When in doubt, use an EVT\_*** function.
+
\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
have a \_\_del\_\_ method that explicitly causes the C++ object to be
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
