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
these objects when they go out of scope. Do they disappear from the GUI?  They
don't. Remember that in wxPython the Python objects are just shadows of the
corresponding 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
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 wxWidgets 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 wxWidgets 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
a flag for functionality that isn't quite implemented yet. Just
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.

\subsection{wxWidgets classes implemented in wxPython}\label{wxpclasses}

The following classes are supported in wxPython. Most provide nearly
full implementations of the public interfaces specified in the C++
documentation, others are less so. They will all be brought as close
as possible to the C++ spec over time.

\subsection{Where to go for help}\label{wxphelp}

Since wxPython is a blending of multiple technologies, help comes from
multiple sources. See
\urlref{http://wxpython.org/}{http://wxpython.org/} for details on
various sources of help, but probably the best source is the
wxPython-users mail list. You can view the archive or subscribe by
going to

\urlref{http://lists.wxwindows.org/mailman/listinfo/wxpython-users}{http://lists.wxwindows.org/mailman/listinfo/wxpython-users}

Or you can send mail directly to the list using this address:
