@class wxXLocale
|
|
|
|
This class represents a locale object used by so-called xlocale API.
|
|
|
|
Unlike wxLocale it doesn't provide any non-trivial operations but simply
|
|
provides a portable wrapper for POSIX @c locale_t type.
|
|
|
|
It exists solely to be provided as an argument to various @c wxFoo_l() functions
|
|
which are the extensions of the standard locale-dependent functions (hence the
|
|
name xlocale). These functions do exactly the same thing as the corresponding
|
|
standard @c foo() except that instead of using the global program locale
|
|
they use the provided wxXLocale object.
|
|
|
|
See @ref group_funcmacro_locale for a list of wxXLocale-enabled functions.
|
|
|
|
Conversely, if a program wanted to output the number in French locale, even if
|
|
the current locale is different, it could use wxXLocale(wxLANGUAGE_FRENCH).
|
|
|
|
|
|
@section xlocale_avail Availability
|
|
|
|
This class is fully implemented only under the platforms where xlocale POSIX
|
|
API or equivalent is available. Currently the xlocale API is available under
|
|
most of the recent Unix systems (including Linux, various BSD and OS X) and
|
|
Microsoft Visual C++ standard library provides a similar API starting from
|
|
version 8 (Visual Studio 2005).
|
|
|
|
If neither POSIX API nor Microsoft proprietary equivalent are available, this
|
|
class is still available but works in degraded mode: the only supported locale
|
|
is the C one and attempts to create wxXLocale object for any other locale will
|
|
fail. You can use the preprocessor macro @c wxHAS_XLOCALE_SUPPORT to test if
|
|
full xlocale API is available or only skeleton C locale support is present.
|
|
|
|
Notice that wxXLocale is new in wxWidgets 2.9.0 and is not compiled in if
|
|
@c wxUSE_XLOCALE was set to 0 during the library compilation.
