\section{Preprocesser symbols defined by wxWindows}\label{cppconst}

Here is the list of preprocessor symbols used in the wxWindows source grouped
by category (and sorted by alphabetical order inside each category).

\subsection{GUI system}

\begin{twocollist}\itemsep=0pt
\twocolitem{\_\_WINDOWS\_\_}{any Windows, yom may also use \_\_WXMSW\_\_}
\twocolitem{\_\_WIN16\_\_}{Win16 API}
\twocolitem{\_\_WIN32\_\_}{Win32 API}
\twocolitem{\_\_WIN95\_\_}{Windows 95 or NT 4.0 and above system (not NT 3.5x)}
\twocolitem{\_\_WXGTK\_\_}{GTK}
\twocolitem{\_\_WXGTK12\_\_}{GTK 1.2 or higher}
\twocolitem{\_\_WXGTK20\_\_}{GTK 2.0 or higher}
\twocolitem{\_\_WXMOTIF\_\_}{Motif}
\twocolitem{\_\_WXMAC\_\_}{Mac OS whether Classic (Mac OS 8/9 TARGET\_CARBON == 0) or Carbon (including Mac OS X TARGET\_CARBON == 1)}
\twocolitem{\_\_WXMGL\_\_}{SciTech Soft MGL (\_\_WXUNIVERSAL\_\_ will be also
defined)}
\twocolitem{\_\_WXMSW\_\_}{Any Windows}
\twocolitem{\_\_WXOS2\_\_}{Identical to \_\_WXPM\_\_}
\twocolitem{\_\_WXPM\_\_}{OS/2 native Presentation Manager}
\twocolitem{\_\_WXSTUBS\_\_}{Stubbed version ('template' wxWin implementation)}
\twocolitem{\_\_WXXT\_\_}{Xt; mutually exclusive with WX\_MOTIF, not
implemented in wxWindows 2.x}
\twocolitem{\_\_WXX11\_\_}{wxX11 (\_\_WXUNIVERSAL\_\_ will be also defined)}
\twocolitem{\_\_WXWINE\_\_}{WINE (i.e. Win32 on Unix)}
\twocolitem{\_\_WXUNIVERSAL\_\_}{wxUniversal port, always defined in addition
to one of the symbols above so this should be tested first.}
\twocolitem{\_\_X\_\_}{any X11-based GUI toolkit except GTK+}
\end{twocollist}

In fact, they should better all start with \_\_WX instead of \_\_ only. The
only GUIs implemented for 2.0 are \_\_WXGTK\_\_, \_\_WXMSW\_\_ and
\_\_WXMOTIF\_\_ yet. Any new ones, please start the define with \_\_WX.

\subsection{Operating systems}

\begin{twocollist}\itemsep=0pt

\twocolitem{\_\_AIX\_\_}{AIX}
\twocolitem{\_\_BSD\_\_}{Any *BSD system}
\twocolitem{\_\_CYGWIN\_\_}{Cygwin: Unix on Win32}
\twocolitem{\_\_DARWIN\_\_}{Mac OS X using the BSD Unix C library (as opposed to using the Metrowerks MSL C/C++ library)}
\twocolitem{\_\_DATA\_GENERAL\_\_}{DG-UX}
\twocolitem{\_\_DOS\_GENERAL\_\_}{DOS (used with wxMGL only)}
\twocolitem{\_\_FREEBSD\_\_}{FreeBSD}
\twocolitem{\_\_HPUX\_\_}{HP-UX (Unix)}

\twocolitem{\_\_VMS\_\_}{VMS}
\twocolitem{\_\_WINDOWS\_\_}{any Windows}
\end{twocollist}

\subsection{Hardware architectures}

Note that not all of these symbols are always defined, it depends on the
compiler used.

\end{twocollist}

\subsection{Compilers}

\begin{twocollist}\itemsep=0pt
