Voici les symboles du préprocesseur utilisés dans les sources wxWidgets, groupés par catégorie (et triés alphabétiquement dans chaque catégorie). Toutes ces macros excepté pour celles du type wxUSE_XXX sont définies si la condition correspondante est vraie, et non-définiers sice n'est pas le cas, elles doivent donc toujours être testées en utilisant ifded et non if.

Il y a deux ports wxWidgets pour Mac OS. L'un d'eux, wxMac, existe en deux versions : Classic et Carbon. La version Classic est la seule à fonctionner sur Mac OS version 8. La version Carbon peut être construite soit comme CFM ou Mach-O (format binaire, comme ELF) Carbon version may be built either as CFM or Mach-O (binary format, like ELF) et l'ancienne peut fonctionner sous OS 9, alors que la dernière ne peut fonctionner que sous OS X. Finnalement, il y a un nouveau port Cocoa qui ne peut également être utilisé que sous OS X. Pour résumer :
The convention is to use the __WX prefix for these symbols, although this has not always been followed.

| WIN32_PLATFORM_WFSP | Microsoft-powered smartphone |
| __BORLANDC__ | Borland C++. The value of the macro corresponds to the compiler version: 500 is 5.0. |

| __XLC__ | AIX compiler |
| __WATCOMC__ | Watcom C++. The value of this macro corresponds to the compiler version, 1100 is 11.0 and 1200 is OpenWatcom. |

Some library features may not be always available even if they were selected by the user. To make it possible to check if this is the case, the library predefines the symbols in the form wxHAS_FEATURE. Unlike wxUSE_FEATURE symbols which are defined by the library user (directly in setup.h or by running configure script) and which must be always defined as either 0 or 1, the wxHAS symbols are only defined if the corresponding feature is available and not defined at all otherwise.
Currently the following symbols exist:
| wxHAS_LARGE_FILES | Defined if wxFile supports files more than 4GB in size. |
| wxHAS_LARGE_FFILES | Defined if wxFFile supports files more than 4GB in size. |
| wxHAS_POWER_EVENTS | Defined if wxPowerEvent are ever generated on the current platform. |
| wxHAS_RADIO_MENU_ITEMS | Defined if the current port supports radio menu items. |
| wxHAS_RAW_KEY_CODES | Defined if raw key codes are supported. |
| wxHAS_REGEX_ADVANCED | Defined if advanced syntax is available in wxRegEx. |
| wxHAS_TASK_BAR_ICON | Defined if wxTaskBarIcon is available on the current platform. |
| __WXWINDOWS__ | always defined in wxWidgets applications, see also wxCHECK_VERSION |
| __WXDEBUG__ | defined in debug mode, undefined in release mode |
| wxUSE_XXX | if defined as 1, feature XXX is active (the symbols of this form are always defined, use #if and not #ifdef to test for them) |
| WX_PRECOMP | is defined if precompiled headers (PCH) are in use. In this case, wx/wxprec.h includes 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 wx/wxprec.h and then, inside ifndef WX_PRECOMP, individual headers you need. |
| _UNICODE and UNICODE | both are defined if wxUSE_UNICODE is set to 1 |
| wxUSE_GUI | this particular feature test macro is defined to 1 when compiling or using the library with the GUI features activated, if it is defined as 0, only wxBase is available. |
| wxUSE_BASE | only used by wxWidgets internally (defined as 1 when building wxBase code, either as a standalone library or as part of the monolithic wxWidgets library, defined as 0 when building GUI library only) |
| wxNO_RTTI | is defined if the compiler RTTI support has been switched off |
| wxNO_EXCEPTIONS | is defined if the compiler support for C++ exceptions has been switched off |
| 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. |
