15 #define _WX_PLATFORM_H_
19 Codewarrior doesn't define any Windows symbols until some headers
28 __WXMAC_CLASSIC__ means ppc non-carbon builds, __WXMAC_CARBON__ means
29 carbon API available (mach or cfm builds) , __WXMAC_OSX__ means mach-o
30 builds, running under 10.2 + only
34 #define __WXMAC_OSX__ 1
35 #define __WXMAC_CARBON__ 1
36 #define __WXMAC_CLASSIC__ 0

53 first define Windows symbols if they're not defined on the command line: we
54 can autodetect everything we need if _WIN32 is defined
56 #if defined(__CYGWIN32__) && !defined(__WXMOTIF__) && !defined(__WXGTK__) \
57 && !defined(__WXX11__)
58 /* for Cygwin, default to wxMSW unless otherwise specified */
75 a lot of code (mistakenly) uses #ifdef _WIN32 to either test for
76 Windows or to test for !__WIN16__, so we must define _WIN32 for
77 Win64 as well to ensure that the existing code continues to work.
84 # endif /* !__WIN64__ */
87 #if (defined(_WIN32) || defined(WIN32) || defined(__NT__) || defined(__WXWINCE__)) \
88 && !defined(__WXMOTIF__) && !defined(__WXGTK__) && !defined(__WXX11__)
98 The library user may override the default setting of WINVER by defining
99 it in his own makefile or project file -- if it is defined, we don't
102 It makes sense to define WINVER as:
103 - either some lowish value (e.g. 0x0302) to not even compile in the
104 features not available in Windows version lower than some given
106 - or to a higher value than the one used by default for the given
107 compiler if you updated its headers to newer version of Platform
108 SDK, e.g. VC6 ships with 0x0400 headers by default but may also
109 work with 0x0500 headers and beyond
112 # if defined(_MSC_VER) && _MSC_VER < 1300
114 VC6 defines some stuff in its default headers which is normally
115 only present if WINVER >= 0x0500 (FLASHW_XXX constants) which
116 means that our usual tests not involving WINVER sometimes fail
117 with it, hence explicitly define a lower WINVER value for it.
119 # define WINVER 0x0400
122 see MSDN for the description of possible WINVER values, this one
123 is the highest one defined right now (Windows Server 2003) and
124 we use it unless it was explicitly overridden by the user to
125 disable recent features support as we check for all of the
126 features we use which could be not available on earlier Windows
127 systems during run-time anyhow, so there is almost no
128 disadvantage in using it.

187 the library compilation options
189 #include "wx/setup.h"
191 /* check the consistency of the settings in setup.h */
192 #include "wx/chkconf.h"
195 adjust the Unicode setting: wxUSE_UNICODE should be defined as 0 or 1
196 and is used by wxWidgets, _UNICODE and/or UNICODE may be defined or used by
197 the system headers so bring these settings in sync
200 /* set wxUSE_UNICODE to 1 if UNICODE or _UNICODE is defined */

218 #endif /* wxUSE_UNICODE */
220 #if defined( __MWERKS__ ) && !defined(__INTEL__)
221 // otherwise MSL headers bring in WIN32 dependant APIs
225 some compilers don't support iostream.h any longer, while some of theme
226 are not updated with <iostream> yet, so override the users setting here

241 old C++ headers (like <iostream.h>) declare classes in the global namespace
242 while the new, standard ones (like <iostream>) do it in std:: namespace
244 using this macro allows constuctions like "wxSTD iostream" to work in
254 OS: first of all, test for MS-DOS platform. We must do this before testing
255 for Unix, because DJGPP compiler defines __unix__ under MS-DOS
