6 XmStringParseText — A function that converts a character string to a
7 compound string

10 #include <Xm/Xm.h>
11 XmString XmStringParseText(
12 XtPointer text,
13 XtPointer *text_end,
14 XmStringTag tag,
15 XmTextType type,
16 XmParseTable parse_table,
17 Cardinal parse_count,
18 XtPointer call_data);

21 XmStringParseText converts characters specified in text to correspond‐
22 ing components in the returned compound string. The resulting compound
23 string consists of at least one locale or charset tag component and a
24 series of XmString text components and other components. The conversion
25 proceeds according to the parse information contained in parse_table.
26 See the Motif Programmer's Guide for more information about parsing and
27 parse tables.
28 · If type is XmCHARSET_TEXT, the associated tag is interpreted as a
30 charset name. If tag has a value of NULL, a charset component
31 whose value is the result of mapping XmFONTLIST_DEFAULT_TAG is
32 created.
33 · If type is XmMULTIBYTE_TEXT or XmWIDECHAR_TEXT, the associated
35 tag is interpreted as a language environment name. If tag has a
36 value of NULL, a locale component with a value of
37 _MOTIF_DEFAULT_LOCALE is created. If type is XmMULTIBYTE_TEXT or
38 XmWIDECHAR_TEXT, tag must be NULL or _MOTIF_DEFAULT_LOCALE.
39 XmStringParseText also scans the string for characters that have
41 matches in parse_table. Whenever a match is found, the text up to that
42 point is concatenated with the mapped component.
43 text Specifies the NULL-terminated string containing characters of
45 a type determined by type. This is updated to point to after
46 the last character scanned.
47 text_end Specifies a pointer into text. If a NULL is supplied to the
49 text_end parameter, then XmStringParseText parses text until
50 NULL is encountered, or until it reaches a point in text
51 where it is directed to stop (for example, by a parse_proc).
52 Otherwise, the value supplied to the text_end parameter is
53 the pointer into text where parsing is to stop, and the
54 returned character is the one where parsing did stop.
55 tag Specifies the tag to be used in creating the result. The
57 type of string tag created (charset or locale) depends on the
58 text type and the passed in tag value. If the tag value is
59 NULL and if type indicates that a charset string tag should
60 be created, the string tag has the value that is the result
61 of mapping XmFONTLIST_DEFAULT_TAG. If type indicates a
62 locale string tag, the string tag has the value
63 _MOTIF_DEFAULT_LOCALE.
64 type Specifies the type of text and the tag type. If a locale tag
66 should be created, type has a value of either XmMULTI‐
67 BYTE_TEXT or XmWIDECHAR_TEXT. If type has value of
68 XmCHARSET_TEXT, a charset tag will be created.
69 parse_table
71 Specifies the parse table to be used in scanning for charac‐
72 ters to be converted to other compound string components.
73 parse_count
75 Specifies the number of entries in parse_table.
76 call_data Specifies data to be passed to the parse procedures.
78
80 Returns a new compound string. The function allocates space to hold
81 the returned compound string. When the application no longer needs the
82 returned compound string, the application should call XmStringFree.
