SYNTAX

ARGUMENTS

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

DESCRIPTION

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