   1 \section{Preprocesser symbols defined by wxWidgets}\label{cppconst}
   2
   3 Here is the list of preprocessor symbols used in the wxWidgets source grouped
   4 by category (and sorted by alphabetical order inside each category). All of
   5 these macros except for \texttt{wxUSE\_XXX} variety is defined if the
   6 corresponding condition is true and undefined if it isn't, so they should be
   7 always tested usin \texttt{#ifdef} and not \texttt{#if}.

  46 Mac situation is a bit confusing so a few extra words to explain it: there are
  47 2 wx ports to Mac OS. One of them, wxMac, exists in 2 versions: Classic and
  48 Carbon. The Classic version is the only one to work on Mac OS version 8. The
  49 Carbon version may be built either as CFM or Mach-O (binary format, like ELF)
  50 and the former may run under OS 9 while the latter only runs under OS X.
  51 Finally, there is a new Cocoa port which can only be used under OS X. To
  52 summarize:
  53 \begin{itemize}
  54     \item If you want to test for all Mac platforms, classic and OS X, you
  55         should test both \texttt{\_\_WXMAC\_\_} and \texttt{\_\_WXCOCOA\_\_}
  56     \item If you want to test for any GUI Mac port under OS X, use
  57         \texttt{\_\_WXOSX\_\_}
  58     \item If you want to test for any port under Mac OS X, including, for
  59         example, wxGTK and also wxBase, use \texttt{\_\_DARWIN\_\_} (see below)
  60 \end{itemize}
  61
  62
  63 Note to implementors: although some of the symbols above don't start with
  64 \texttt{\_\_WX} prefix, they really should always use it, so please do start
  65 any new symbols with it.
