XtSetLanguageProc(3Xt)XtSetLanguageProc(3Xt)NAMEXtSetLanguageProc - set the language procedure
SYNOPSIS
Widget XtSetLanguageProc(app_context, proc, client_data)
XtAppContext app_context;
XtLanguageProc proc;
XtPointer client_data;
ARGUMENTS
Specifies the application context in which the language procedure is to
be used, or NULL. Specifies the language procedure, or NULL. Speci‐
fies additional client data to be passed to the language procedure when
it is called.
DESCRIPTIONXtSetLanguageProc sets the language procedure that will be called from
XtDisplayInitialize for all subsequent Displays initialized in the
specified application context. If app_context is NULL, the specified
language procedure is registered in all application contexts created by
the calling process, including any future application contexts that may
be created. If proc is NULL a default language procedure is registered.
XtSetLanguageProc returns the previously registered language procedure.
If a language procedure has not yet been registered, the return value
is unspecified but if this return value is used in a subsequent call to
XtSetLanguageProc, it will because the default language procedure to be
registered.
The default language procedure does the following: Sets the locale
according to the environment. On ANSI C-based systems this is done by
calling setlocale (LC_ALL, language). If an error is encountered a
warning message is issued with XtWarning. Calls XSupportsLocale to
verify that the current locale is supported. If the locale is not sup‐
ported, a warning message is issued with XtWarning and the locale is
set to “C”. Calls XSetLocaleModifiers specifying the empty string.
Returns the value of the current locale. On ANSI C-based systems this
is the return value from a final call to setlocal (LC_ALL, NULL).
A client wishing to use this mechanism to establish locale can do so by
calling XtSetLanguageProc prior to XtDisplayInitialize.
