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_. | |

71 | There are two wxWidgets ports to Mac OS X. One of them, wxOSX is the successor of the | |
72 | venerable wxMac, it currently exists in three versions: Carbon and Cocoa for the | |
73 | desktop and a very early iPhone port. And there is the Cocoa port named wxCocoa | |
74 | which has not been updated very actively since beginning 2008. To summarize: | |
75 | ||
76 | @li If you want to test for wxOSX on the desktop, use | |
77 | @c __WXOSX_MAC__. | |
78 | @li If you want to test for wxOSX on the iPhone, use | |
79 | @c __WXOSX_IPHONE__. | |
80 | @li If you want to test for any GUI Mac port under OS X, use | |
81 | @c __WXOSX_OR_COCOA__. | |
82 | @li If you want to test for any port under Mac OS X, including, for | |
83 | example, wxGTK and also wxBase, use @c __DARWIN__ (see below). | |
84 | ||
85 | The convention is to use the @c __WX prefix for these | |
86 | symbols, although this has not always been followed. | |

182 | @section page_cppconst_featuretests Feature tests | |
183 | ||
184 | Some library features may not be always available even if they were selected | |
185 | by the user. To make it possible to check if this is the case, the library | |
186 | predefines the symbols in the form @c wxHAS_FEATURE. Unlike | |
187 | @c wxUSE_FEATURE symbols which are defined by the library user (directly | |
188 | in @c setup.h or by running configure script) and which must be always | |
189 | defined as either 0 or 1, the @c wxHAS symbols are only defined if | |
190 | the corresponding feature is available and not defined at all otherwise. | |
191 | ||
192 | Currently the following symbols exist: | |
193 | ||
194 | @beginDefList | |
195 | @itemdef{wxHAS_ATOMIC_OPS, Defined if wxAtomicInc() and wxAtomicDec() functions | |
196 | have an efficient (CPU-specific) implementation. Notice that the functions | |
197 | themselves are always available but can be prohibitively slow to use when | |
198 | implemented in a generic way, using a critical section.} | |
199 | @itemdef{wxHAS_CONFIG_TEMPLATE_RW, Defined if the currently used compiler | |
200 | supports template Read() and Write() methods in wxConfig.} | |
201 | @itemdef{wxHAS_LARGE_FILES, Defined if wxFile supports files more than 4GB in | |
202 | size (notice that you must include @c wx/filefn.h before testing for this | |
203 | symbol).} | |
204 | @itemdef{wxHAS_LARGE_FFILES, Defined if wxFFile supports files more than 4GB in | |
205 | size (notice that you must include @c wx/filefn.h before testing for this | |
206 | symbol).} | |
207 | @itemdef{wxHAS_MULTIPLE_FILEDLG_FILTERS, Defined if wxFileDialog supports multiple ('|'-separated) filters.} | |
208 | @itemdef{wxHAS_POWER_EVENTS, Defined if wxPowerEvent are ever generated on the current platform.} | |
209 | @itemdef{wxHAS_RADIO_MENU_ITEMS, | |
210 | Defined if the current port supports radio menu items (see wxMenu::AppendRadioItem).} | |
211 | @itemdef{wxHAS_RAW_BITMAP, Defined if direct access to bitmap data using the classes in @c wx/rawbmp.h is supported.} | |
212 | @itemdef{wxHAS_RAW_KEY_CODES, Defined if raw key codes (see wxKeyEvent::GetRawKeyCode are supported.} | |
213 | @itemdef{wxHAS_REGEX_ADVANCED, Defined if advanced syntax is available in wxRegEx.} | |
214 | @itemdef{wxHAS_TASK_BAR_ICON, Defined if wxTaskBarIcon is available on the current platform.} | |

219 | @section page_cppconst_msvc_setup_h Libraries selection for MSVC setup.h | |
220 | ||
221 | Microsoft Visual C++ users may use the special @c wx/setup.h file for this | |
222 | compiler in @c include/msvc subdirectory. This file implicitly links in all the | |
223 | wxWidgets libraries using MSVC-specific pragmas which usually is much more | |
224 | convenient than manually specifying the libraries list in all of the project | |
225 | configurations. However sometimes linking with all the libraries is not | |
226 | desirable, for example because some of them were not built and this is where | |
227 | the symbols in this section can be helpful: defining them allows to not link | |
228 | with the corresponding library. The following symbols are honoured: | |
229 | - wxNO_ADV_LIB | |
230 | - wxNO_AUI_LIB | |
231 | - wxNO_HTML_LIB | |
232 | - wxNO_MEDIA_LIB | |
233 | - wxNO_NET_LIB | |
234 | - wxNO_PROPGRID_LIB | |
235 | - wxNO_QA_LIB | |
236 | - wxNO_RICHTEXT_LIB | |
237 | - wxNO_XML_LIB | |
238 | - wxNO_REGEX_LIB | |
239 | - wxNO_EXPAT_LIB | |
240 | - wxNO_JPEG_LIB | |
241 | - wxNO_PNG_LIB | |
242 | - wxNO_TIFF_LIB | |
243 | - wxNO_ZLIB_LIB | |
244 | ||
245 | Notice that the base library is always included and the core is always included | |
246 | for the GUI applications (i.e. those which don't define @c wxUSE_GUI as 0). | |

262 | @itemdef{WX_PRECOMP, | |
263 | is defined if precompiled headers (PCH) are in use. In | |
264 | this case, @c wx/wxprec.h includes @c wx/wx.h which, in turn, | |
265 | includes a number of wxWidgets headers thus making it unnecessary to include | |
266 | them explicitly. However if this is not defined, you do need to include them | |
267 | and so the usual idiom which allows to support both cases is to first include | |
268 | @c wx/wxprec.h} and then, inside @ifndef_ WX_PRECOMP, individual | |
269 | headers you need.} | |

282 | @itemdef{wxNO_THREADS, | |
283 | if this macro is defined, the compilation options | |
284 | don't include compiler flags needed for multithreaded code generation. This | |
