@page page_cppconst 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 @c 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:
|
|
|
|
@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_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_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).

@itemdef{WX_PRECOMP,

is defined if precompiled headers (PCH) are in use. In

this case, @c wx/wxprec.h includes @c 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
|
|
@c wx/wxprec.h} and then, inside @ifndef_ WX_PRECOMP, individual
|
|
headers you need.}

@itemdef{_UNICODE and UNICODE, both are defined if wxUSE_UNICODE is set to @c 1}

this particular feature test macro is defined to 1

packages cannot be used neither.}
