NAME
       XmbDrawText, XwcDrawText - draw text using multiple font sets

SYNTAX
       void XmbDrawText(display, d, gc, x, y, items, nitems)
             Display *display;
             Drawable d;
             GC gc;
             int x, y;
             XmbTextItem *items;
             int nitems;

       void XwcDrawText(display, d, gc, x, y, items, nitems)
             Display *display;
             Drawable d;
             GC gc;
             int x, y;
             XwcTextItem *items;
             int nitems;

ARGUMENTS
       d         Specifies the drawable.

       display   Specifies the connection to the X server.

       gc        Specifies the GC.

       items     Specifies an array of text items.

       nitems    Specifies the number of text items in the array.

       x
       y         Specify the x and y coordinates.

DESCRIPTION
       XmbDrawText and XwcDrawText allow complex spacing and font set shifts
       between text strings.  Each text item is processed in turn, with the
       origin of a text element advanced in the primary draw direction by
       the escapement of the previous text item.  A text item delta
       specifies an additional escapement of the text item drawing origin in
       the primary draw direction.  A font_set member other than None in an
       item causes the font set to be used for this and subsequent text
       items in the text_items list.  Leading text items with font_set
       member set to None will not be drawn.

       XmbDrawText and XwcDrawText do not perform any context-dependent
       rendering between text segments.  Clients may compute the drawing
       metrics by passing each text segment to XmbTextExtents and
       XwcTextExtents or XmbTextPerCharExtents and XwcTextPerCharExtents.
       When the XFontSet has missing charsets, each unavailable character is
       drawn with the default string returned by XCreateFontSet.  The
       behavior for an invalid codepoint is undefined.

STRUCTURES
       The XmbTextItem structure contains:
       typedef struct {
            char *chars;        /* pointer to string */
            int nchars;         /* number of characters */
            int delta;          /* pixel delta between strings */
            XFontSet font_set;  /* fonts, None means don't change */
       } XmbTextItem;
The XwcTextItem structure contains:
typedef struct {
     wchar_t *chars;     /* pointer to wide char string */
     int nchars;         /* number of wide characters */
     int delta;          /* pixel delta between strings */
     XFontSet font_set;  /* fonts, None means don't change */
} XwcTextItem;
