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

|
There are two wxWidgets ports to Mac OS. One of them, wxMac, exists in two versions: Classic and
|
|
Carbon. The Classic version is the only one to work on Mac OS version 8. The
|
|
Carbon version may be built either as CFM or Mach-O (binary format, like ELF)
|
|
and the former may run under OS 9 while the latter only runs under OS X.
|
|
Finally, there is a new Cocoa port which can only be used under OS X. To
|
|
summarize:
|
|
|
|
\begin{itemize}
|
|
\item If you want to test for all Mac platforms, classic and OS X, you
|
|
should test both \texttt{\_\_WXMAC\_\_} and \texttt{\_\_WXCOCOA\_\_}.
|
|
\item If you want to test for any GUI Mac port under OS X, use
|
|
\texttt{\_\_WXOSX\_\_}.
|
|
\item If you want to test for any port under Mac OS X, including, for
|
|
example, wxGTK and also wxBase, use \texttt{\_\_DARWIN\_\_} (see below).
|
|
\end{itemize}
|
|
|
|
The convention is to use the \texttt{\_\_WX} prefix for these
|
|
symbols, although this has not always been followed.

also \helpref{wxCHECK\_VERSION}{wxcheckversion}}

(the symbols of this form are always defined, use \#if and not \#ifdef to test

for them)}

\twocolitem{WX\_PRECOMP}{is defined if precompiled headers (PCH) are in use. In
|
|
this case, \texttt{wx/wxprec.h} includes \texttt{wx/wx.h} which, in turn,
|
|
includes a number of wxWidgets headers thus making it unnecessary to include
|
|
them explicitly. However if this is not defined, you do need to include them
|
|
and so the usual idiom which allows to support both cases is to first include
|
|
\texttt{wx/wxprec.h} and then, inside \texttt{#ifndef WX\_PRECOMP}, individual
|

headers you need.}

defined as $0$, only wxBase is available.}

|
|
building wxBase code, either as a standalone library or as part of the

monolithic wxWidgets library, defined as $0$ when building GUI library only)}

\twocolitem{wxNO\_RTTI}{is defined if the compiler RTTI support has been switched off}

\twocolitem{wxNO\_EXCEPTIONS}{is defined if the compiler support for C++
|
|
exceptions has been switched off}
|

\twocolitem{wxNO\_THREADS}{if this macro is defined, the compilation options
|
|
don't include compiler flags needed for multithreaded code generation. This
|
|
implies that wxUSE\_THREADS is $0$ and also that other (non wx-based) threading
|
|
packages cannot be used neither.}
