DESCRIPTION

34       The  XmbDrawText, XwcDrawText and Xutf8DrawText functions allow complex
35       spacing and font set shifts between text strings.  Each  text  item  is
36       processed  in  turn,  with the origin of a text element advanced in the
37       primary draw direction by the escapement of the previous text item.   A
38       text  item  delta  specifies  an additional escapement of the text item
39       drawing origin in the primary draw direction.  A font_set member  other
40       than None in an item causes the font set to be used for this and subse‐
41       quent text items in the text_items list.  Leading  text  items  with  a
42       font_set member set to None will not be drawn.
43
44       XmbDrawText,  XwcDrawText and Xutf8DrawText do not perform any context-
45       dependent rendering between text segments.   Clients  may  compute  the
46       drawing metrics by passing each text segment to XmbTextExtents, XwcTex‐
47       tExtents, Xutf8TextExtents or XmbTextPerCharExtents,  XwcTextPerCharEx‐
48       tents.    Xutf8TextPerCharExtents.    When  the  XFontSet  has  missing
49       charsets, each unavailable character is drawn with the  default  string
50       returned  by  XCreateFontSet.  The behavior for an invalid codepoint is
51       undefined.
52
53       The function Xutf8DrawText is an extension introduced  by  The  XFree86
54       Project,  Inc.,  in  their 4.0.2 release.  Its presence is indicated by
55       the macro X_HAVE_UTF8_STRING.

STRUCTURES

58       The XmbTextItem structure contains:
59       typedef struct {
60               char *chars;    /* pointer to string */
61               int nchars;     /* number of bytes */
62               int delta;      /* pixel delta between strings */
63               XFontSet font_set;      /* fonts, None means don't change */
64       } XmbTextItem;
65       The XwcTextItem structure contains:
66       typedef struct {
67               wchar_t *chars; /* pointer to wide char string */
68               int nchars;     /* number of wide characters */
69               int delta;      /* pixel delta between strings */
70               XFontSet font_set;      /* fonts, None means don't change */
71       } XwcTextItem;
