- @page page_cppconst Preprocessor symbols defined by wxWidgets
- 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 @c wxUSE_XXX variety is defined if the
- corresponding condition is @true and undefined if it isn't, so they should be
- always tested using @ifdef_ and not @if_.

- There are two wxWidgets ports to Mac OS X. One of them, wxOSX is the successor of the
- venerable wxMac, it currently exists in three versions: Carbon and Cocoa for the
- desktop and a very early iPhone port. And there is the Cocoa port named wxCocoa
- which has not been updated very actively since beginning 2008. To summarize:
- @li If you want to test for wxOSX on the desktop, use
- @c __WXOSX_MAC__.
- @li If you want to test for wxOSX on the iPhone, use
- @c __WXOSX_IPHONE__.
- @li If you want to test for any GUI Mac port under OS X, use
- @c __WXOSX_OR_COCOA__.
- @li If you want to test for any port under Mac OS X, including, for
- example, wxGTK and also wxBase, use @c __DARWIN__ (see below).
- The convention is to use the @c __WX prefix for these
- symbols, although this has not always been followed.

- @endDefList
- @section page_cppconst_featuretests Feature tests
- 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 @c wxHAS_FEATURE. Unlike
- @c wxUSE_FEATURE symbols which are defined by the library user (directly
- in @c setup.h or by running configure script) and which must be always
- defined as either 0 or 1, the @c wxHAS symbols are only defined if
- the corresponding feature is available and not defined at all otherwise.
- Currently the following symbols exist:
- @beginDefList
- @itemdef{wxHAS_ATOMIC_OPS, Defined if wxAtomicInc() and wxAtomicDec() functions
- have an efficient (CPU-specific) implementation. Notice that the functions
- themselves are always available but can be prohibitively slow to use when
- implemented in a generic way, using a critical section.}
- @itemdef{wxHAS_CONFIG_TEMPLATE_RW, Defined if the currently used compiler
- supports template Read() and Write() methods in wxConfig.}
- @itemdef{wxHAS_LARGE_FILES, Defined if wxFile supports files more than 4GB in
- size (notice that you must include @c wx/filefn.h before testing for this
- symbol).}
- @itemdef{wxHAS_LARGE_FFILES, Defined if wxFFile supports files more than 4GB in
- size (notice that you must include @c wx/filefn.h before testing for this
- symbol).}
- @itemdef{wxHAS_MULTIPLE_FILEDLG_FILTERS, Defined if wxFileDialog supports multiple ('|'-separated) filters.}
- @itemdef{wxHAS_POWER_EVENTS, Defined if wxPowerEvent are ever generated on the current platform.}
- @itemdef{wxHAS_RADIO_MENU_ITEMS,
- Defined if the current port supports radio menu items (see wxMenu::AppendRadioItem).}
- @itemdef{wxHAS_RAW_BITMAP, Defined if direct access to bitmap data using the classes in @c wx/rawbmp.h is supported.}
- @itemdef{wxHAS_RAW_KEY_CODES, Defined if raw key codes (see wxKeyEvent::GetRawKeyCode are supported.}
- @itemdef{wxHAS_REGEX_ADVANCED, Defined if advanced syntax is available in wxRegEx.}
- @itemdef{wxHAS_TASK_BAR_ICON, Defined if wxTaskBarIcon is available on the current platform.}
- @endDefList
- @section page_cppconst_msvc_setup_h Libraries selection for MSVC setup.h
- Microsoft Visual C++ users may use the special @c wx/setup.h file for this
- compiler in @c include/msvc subdirectory. This file implicitly links in all the
- wxWidgets libraries using MSVC-specific pragmas which usually is much more
- convenient than manually specifying the libraries list in all of the project
- configurations. However sometimes linking with all the libraries is not
- desirable, for example because some of them were not built and this is where
- the symbols in this section can be helpful: defining them allows to not link
- with the corresponding library. The following symbols are honoured:
- - wxNO_ADV_LIB
- - wxNO_AUI_LIB
- - wxNO_HTML_LIB
- - wxNO_MEDIA_LIB
- - wxNO_NET_LIB
- - wxNO_PROPGRID_LIB
- - wxNO_QA_LIB
- - wxNO_RICHTEXT_LIB
- - wxNO_XML_LIB
- - wxNO_REGEX_LIB
- - wxNO_EXPAT_LIB
- - wxNO_JPEG_LIB
- - wxNO_PNG_LIB
- - wxNO_TIFF_LIB
- - wxNO_ZLIB_LIB
- Notice that the base library is always included and the core is always included
- for the GUI applications (i.e. those which don't define @c wxUSE_GUI as 0).
- @section page_cppconst_miscellaneous Miscellaneous
- @beginDefList
- @itemdef{__WXWINDOWS__,
- always defined in wxWidgets applications, see also wxCHECK_VERSION}
- @itemdef{wxDEBUG_LEVEL, defined as 1 by default, may be pre-defined as 0 before
- including wxWidgets headers to disable generation of any code at all
- for the assertion macros, see @ref overview_debugging}
- @itemdef{__WXDEBUG__, defined if wxDEBUG_LEVEL is 1 or more, undefined otherwise}
- @itemdef{wxUSE_XXX,
- if defined as 1, feature XXX is active, see the
- @ref page_wxusedef (the symbols of this form are always defined,
- use @if_ and not @ifdef_ to test for them)}
- @itemdef{WX_PRECOMP,
- is defined if precompiled headers (PCH) are in use. In
- this case, @c wx/wxprec.h includes @c 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
- @c wx/wxprec.h} and then, inside @ifndef_ WX_PRECOMP, individual
- headers you need.}
- @itemdef{_UNICODE and UNICODE, both are defined if wxUSE_UNICODE is set to @c 1}
- @itemdef{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 @c 0, only wxBase is available.}
- @itemdef{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)}
- @itemdef{wxNO_RTTI, is defined if the compiler RTTI support has been switched off}
- @itemdef{wxNO_EXCEPTIONS,
- is defined if the compiler support for C++ exceptions has been switched off}
- @itemdef{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.}
- @itemdef{WXMAKINGDLL_XXX,
- used internally and defined when building the
- library @c XXX as a DLL; when a monolithic wxWidgets build is used only a
- single @c WXMAKINGDLL symbol is defined}
- @itemdef{WXUSINGDLL,
- defined when compiling code which uses wxWidgets as a DLL/shared library}
- @itemdef{WXBUILDING,
- defined when building wxWidgets itself, whether as a static or shared library}
- @itemdef{wxNO_T,
- may be predefined to prevent the library from defining _T() macro}
