  12  @page page_cppconst Preprocessor symbols defined by wxWidgets
  13
  14  These are preprocessor symbols used in the wxWidgets source, grouped
  15  by category (and sorted by alphabetical order inside each category).
  16  All of these macros except for the @c wxUSE_XXX variety is defined if the
  17  corresponding condition is @true and undefined if it isn't, so they should be
  18  always tested using @ifdef_ and not @if_.

  68  There are two wxWidgets ports to Mac OS. One of them, wxMac, exists in two versions:
  69  Classic and Carbon. The Classic version is the only one to work on Mac OS version 8.
  70  The Carbon version may be built either as CFM or Mach-O (binary format, like ELF)
  71  and the former may run under OS 9 while the latter only runs under OS X.
  72  Finally, there is a new Cocoa port which can only be used under OS X. To
  73  summarize:
  74
  75  @li If you want to test for all Mac platforms, classic and OS X, you
  76      should test both @c __WXMAC__ and @c __WXCOCOA__.
  77  @li If you want to test for any GUI Mac port under OS X, use
  78      @c __WXOSX__.
  79  @li If you want to test for any port under Mac OS X, including, for
  80      example, wxGTK and also wxBase, use @c __DARWIN__ (see below).
  81
  82  The convention is to use the @c __WX prefix for these
  83  symbols, although this has not always been followed.

 179  Some library features may not be always available even if they were selected
 180  by the user. To make it possible to check if this is the case, the library
 181  predefines the symbols in the form @c wxHAS_FEATURE. Unlike
 182  @c wxUSE_FEATURE symbols which are defined by the library user (directly
 183  in @c setup.h or by running configure script) and which must be always
 184  defined as either $0$ or $1$, the @c wxHAS symbols are only defined if
 185  the corresponding feature is available and not defined at all otherwise.
 186
 187  Currently the following symbols exist:
 188
 189  @beginDefList
 190  @itemdef{wxHAS_LARGE_FILES, Defined if wxFile supports files more than 4GB in size.}
 191  @itemdef{wxHAS_LARGE_FFILES, Defined if wxFFile supports files more than 4GB in size.}
 192  @itemdef{wxHAS_POWER_EVENTS, Defined if wxPowerEvent are ever generated on the current platform.}
 193  @itemdef{wxHAS_RADIO_MENU_ITEMS,
 194           Defined if the current port supports radio menu items (see wxMenu::AppendRadioItem).}
 195  @itemdef{wxHAS_RAW_KEY_CODES, Defined if raw key codes (see wxKeyEvent::GetRawKeyCode are supported.}
 196  @itemdef{wxHAS_REGEX_ADVANCED, Defined if advanced syntax is available in wxRegEx.}
 197  @itemdef{wxHAS_TASK_BAR_ICON, Defined if wxTaskBarIcon is available on the current platform.}

 209           if defined as $1$, feature XXX is active, see the
 210           @ref page_wxusedef (the symbols of this form are always defined,
 211           use @if_ and not @ifdef_ to test for them)}
 212  @itemdef{WX_PRECOMP,
 213           is defined if precompiled headers (PCH) are in use. In
 214           this case, @c wx/wxprec.h includes @c wx/wx.h which, in turn,
 215           includes a number of wxWidgets headers thus making it unnecessary to include
 216           them explicitly. However if this is not defined, you do need to include them
 217           and so the usual idiom which allows to support both cases is to first include
 218           @c wx/wxprec.h} and then, inside @ifndef_ WX_PRECOMP, individual
 219           headers you need.}
 220  @itemdef{_UNICODE and UNICODE, both are defined if wxUSE_UNICODE is set to @c 1}
 221  @itemdef{wxUSE_GUI,
 222           this particular feature test macro is defined to $1$
 223           when compiling or using the library with the GUI features activated,
 224           if it is defined as @c 0, only wxBase is available.}
 225  @itemdef{wxUSE_BASE,
 226           only used by wxWidgets internally (defined as $1$ when
 227           building wxBase code, either as a standalone library or as part of the
 228           monolithic wxWidgets library, defined as $0$ when building GUI library only)}
 229  @itemdef{wxNO_RTTI, is defined if the compiler RTTI support has been switched off}
 230  @itemdef{wxNO_EXCEPTIONS,
 231           is defined if the compiler support for C++ exceptions has been switched off}
 232  @itemdef{wxNO_THREADS,
 233           if this macro is defined, the compilation options
 234           don't include compiler flags needed for multithreaded code generation. This
 235           implies that wxUSE_THREADS is $0$ and also that other (non-wx-based) threading
 236           packages cannot be used neither.}
 237  @itemdef{WXMAKINGDLL_XXX,
 238           used internally and defined when building the
 239           library @c XXX as a DLL; when a monolithic wxWidgets build is used only a
 240           single @c WXMAKINGDLL symbol is defined}
