-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:
+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 all Mac platforms, classic and OS X, you
- should test both @c __WXMAC__ and @c __WXCOCOA__.
+@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__.
+ @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).

+@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
+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_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_3STATE_CHECKBOX, Defined if wxCheckBox supports wxCHK_3STATE
+ flag, i.e. is capable of showing three states and not only the usual two.
+ Currently defined for almost all ports.}
+@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_BITMAPTOGGLEBUTTON, Defined in @c wx/tglbtn.h if
+ wxBitmapToggleButton class is available in addition to wxToggleButton.}
+@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_LONG_LONG_T_DIFFERENT_FROM_LONG, Defined if compiler supports a
+ 64 bit integer type (available as @c wxLongLong_t) and this type is
+ different from long. Notice that, provided wxUSE_LONGLONG is not turned
+ off, some 64 bit type is always available to wxWidgets programs and this
+ symbol only indicates a presence of such primitive type. It is useful to
+ decide whether some function should be overloaded for both
+ <code>long</code> and <code>long long</code> types.}
+@itemdef{wxHAS_MULTIPLE_FILEDLG_FILTERS, Defined if wxFileDialog supports multiple ('|'-separated) filters.}
+@itemdef{wxHAS_IMAGES_IN_RESOURCES, Defined if <a href="http://en.wikipedia.org/wiki/Resource_(Windows)">
+ Windows resource files</a> or OS/2 resource files are available on the current platform.}
@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
+@section page_cppconst_msvc_setup_h Library Selection for MSVC
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
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_WEBVIEW_LIB
- wxNO_XML_LIB
- wxNO_REGEX_LIB
- wxNO_EXPAT_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).
+If the makefiles have been used to build the libraries from source and the @c CFG
+variable has been set to specify a different output path for that particular
+configuration of build then the @c wxCFG preprocessor symbol should be set in
+the project that uses wxWidgets to the same value as the @c CFG variable in
+order for the correct @c wx/setup.h file to automatically be included for that
+configuration.
