SYNTAX

9       Widget XtSetLanguageProc(XtAppContext app_context, XtLanguageProc proc,
10              XtPointer client_data);
11

ARGUMENTS

13       app_context
14                 Specifies the application context in which the language pro‐
15                 cedure is to be used, or NULL.
16
17       proc      Specifies the language procedure, or NULL.
18
19       client_data
20                 Specifies additional client data to be passed to the language
21                 procedure when it is called.

DESCRIPTION

24       XtSetLanguageProc sets the language procedure that will be called from
25       XtDisplayInitialize for all subsequent Displays initialized in the
26       specified application context. If app_context is NULL, the specified
27       language procedure is registered in all application contexts created by
28       the calling process, including any future application contexts that may
29       be created. If proc is NULL a default language procedure is registered.
30       XtSetLanguageProc returns the previously registered language procedure.
31       If a language procedure has not yet been registered, the return value
32       is unspecified but if this return value is used in a subsequent call to
33       XtSetLanguageProc, it will cause the default language procedure to be
34       registered.
35
36       The default language procedure does the following:
37
38       ·    Sets the locale according to the environment. On ANSI C-based sys‐
39            tems this is done by calling setlocale( LC_ALL, language ). If an
40            error is encountered a warning message is issued with XtWarning.
41
42       ·    Calls XSupportsLocale to verify that the current locale is sup‐
43            ported. If the locale is not supported, a warning message is
44            issued with XtWarning and the locale is set to ``C''.
45
46       ·    Calls XSetLocaleModifiers specifying the empty string.
47
48       ·    Returns the value of the current locale. On ANSI C-based systems
49            this is the return value from a final call to setlocale( LC_ALL,
50            NULL ).
51
52       A client wishing to use this mechanism to establish locale can do so by
53       calling XtSetLanguageProc prior to XtDisplayInitialize.
