   
preprocessor symbols defined by wxwidgets
these are preprocessor symbols used in the wxwidgets source, grouped
by category (and sorted by alphabetical order inside each category). all of
these macros except for the wxuse_xxx variety is defined if the
corresponding condition is true and undefined if it isn't, so they should be
always tested using ifdef and not if.

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:
- if you want to test for all mac platforms, classic and os x, you
should test both __wxmac__ and __wxcocoa__.
- if you want to test for any gui mac port under os x, use
__wxosx__.
- if you want to test for any port under mac os x, including, for
example, wxgtk and also wxbase, use __darwin__ (see below).
the convention is to use the __wx prefix for these
symbols, although this has not always been followed.

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 wxhas_feature. unlike
wxuse_feature symbols which are defined by the library user (directly
in setup.h or by running configure script) and which must be always
defined as either 0 or 1, the wxhas symbols are only defined if
the corresponding feature is available and not defined at all otherwise.
currently the following symbols exist:
|
wxhas_large_files
|
defined if wxfile supports
files more than 4gb in size.
|
|
wxhas_large_ffiles
|
defined if wxffile
supports files more than 4gb in size.
|
|
wxhas_power_events
|
defined if
wxpowerevent are ever generated on the current platform.
|
|
wxhas_radio_menu_items
|
defined if the current port supports
radio menu items.
|
|
wxhas_raw_key_codes
|
defined if
raw key codes are supported.
|
|
wxhas_regex_advanced
|
defined if advanced syntax is available in
wxregex.
|
|
wxhas_task_bar_icon
|
defined if
wxtaskbaricon is available on the current platform.
|
miscellaneous
|
__wxwindows__
|
always defined in wxwidgets applications, see
also wxcheck_version
|
|
__wxdebug__
|
defined in debug mode, undefined in release mode
|
|
wxuse_xxx
|
if defined as 1, feature xxx is active
(the symbols of this form are always defined, use #if and not #ifdef to test
for them)
|
|
wx_precomp
|
is defined if precompiled headers (pch) are in use. in
this case, wx/wxprec.h includes wx/wx.h which, in turn,
includes a number of wxwidgets headers thus making it unnecessary to include
them explicitly. however if this is not defined, you do need to include them
and so the usual idiom which allows to support both cases is to first include
wx/wxprec.h and then, inside ifndef wx_precomp, individual
headers you need.
|
|
_unicode and unicode
|
both are defined if wxuse_unicode is set to 1
|
|
wxuse_gui
|
this particular feature test macro is defined to 1
when compiling or using the library with the gui features activated, if it is
defined as 0, only wxbase is available.
|
|
wxuse_base
|
only used by wxwidgets internally (defined as 1 when
building wxbase code, either as a standalone library or as part of the
monolithic wxwidgets library, defined as 0 when building gui library only)
|
|
wxno_rtti
|
is defined if the compiler rtti support has been switched off
|
|
wxno_exceptions
|
is defined if the compiler support for c++
exceptions has been switched off
|
|
wxno_threads
|
if this macro is defined, the compilation options
don't include compiler flags needed for multithreaded code generation. this
implies that wxuse_threads is 0 and also that other (non-wx-based) threading
packages cannot be used neither.
