 | |
| 
 | |
| 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:
 | |
| 
 | |
| @li If you want to test for all Mac platforms, classic and OS X, you
 | |
|     should test both @c __WXMAC__ and @c __WXCOCOA__.
 | |
| @li If you want to test for any GUI Mac port under OS X, use
 | |
|     @c __WXOSX__.
 | |
| @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.

| @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.}
 | |
| @itemdef{wxHAS_LARGE_FFILES, Defined if wxFFile supports files more than 4GB in size.}
 | |
| @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.}

 | |
| 
 | |
| 
 | |
| @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).
