wxPython is organized as a Python package. This means that the
directory containing the results of the build process should be a
-subdirectory of a directory on the \tt{PYTHONPATH}. (And preferably should
+subdirectory of a directory on the {\tt PYTHONPATH}. (And preferably should
be named wxPython.) You can control where the build process will dump
-wxPython by setting the \tt{TARGETDIR} variable for the build utility (see
+wxPython by setting the {\tt TARGETDIR} variable for the build utility (see
below).

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
+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{build}.bat in a directory on the PATH that contains:

The build.py script actually generates a Makefile based on what it
finds on your system and information found in the build.cfg file.

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 Try executing the demo program. For example:
-\tt{python demo.py}

To run it without requiring a console on Win32, you can use the
-\tt{pythonw.exe} version of Python either from the command line or from a
+{\tt pythonw.exe} version of Python either from the command line or from a
shortcut.

enough to notice the similarities in the classes used.
Take a look at the following wxPython program. You can find a similar
-program in the \tt{wxPython/demo} directory, named \tt{DialogUnits.py}. If your
+program in the {\tt wxPython/demo} directory, named {\tt DialogUnits.py}. If your
Python and wxPython are properly installed, you should be able to run
it by issuing this command:
\begin{indented}{1cm}
- \bftt{python DialogUnits.py}
+ {\bf\tt python DialogUnits.py}
\end{indented}

\item At line 2 the wxPython classes, constants, and etc. are imported
into the current module's namespace. If you prefer to reduce
-namespace pollution you can use "\tt{from wxPython import wx}" and
+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}".
+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
+\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
-\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
+{\em standard} events are attached to windows that have the associated

+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
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

loop which continues until the application terminates or all the top
level windows are closed.
